Abdel
Amer
This is the last paper on the revision of Noctuidae in Egypt, we revised 11 subfamilies (from total 16 subfamilies). In this study, we are exposed to revise the last five subfamilies which are Bryophilinae, Condicinae, Cuculliinae, Eriopinae, and Eustrotiinae. These subfamilies contain 40 species under 10 genera. Subfamily Eustrotiinae Grote, 1882 is the largest subfamily (in this study) with 11 species and 3 genera, followed by Subfamily Bryophilinae Guenée, 1852 with 11 species under one genera while Subfamily Eriopinae Herrich-Schäffer, [1851] is the smallest subfamily containing two species under one genus. We added three Annexes, one for the recent situation of Family Noctuidae; 2nd a list of noctuid types in Egypt and the 3rd is the complete recent list of family Noctuidae in Egypt.

Bioactivity of Plant Essential Oil against Potato Tuber Moth,Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae).
R.
Morey

Khandagle
Phthorimaea operculella (Potato tuber moth) is a destructive pest of stored potatoes and potato crops, primarily in subtropical areas of the globe. It is a pest of the field as well as storage, the larvae damage the crop through the foliage, stem, and tubers too. The manifestation of potato tuber moth primes to high economic damages in production worldwide. Post-harvest protection of the potato tubers becomes important and is challenging. A treatment with chemical agents is a possible strategy but cannot be recommended for food items hence alternative methods become important in control of these moths. The present study deals with the assessment of plant oils of Cinnamomum verum, Cupressuss sempervirens and Cymbopogon nardus. These plant oils were used to evaluate the larvicidal, adulticidal, Insect growth regulatory, repellency and oviposition deterrence activities against potato tuber moth. Results of the present work indicated that all the test oils show some promise as pest control agents against P. operculella. Oil of C. verum has exhibited promising toxic action (larvicidal LC50 = 110.10 μg/cm2, adulticidal LC50 = 49.78 μg/cm2). The oil of C. nardus caused promising IGR activity (delay in development = 16.2 days) All three plant oils have shown multifarious activity and can be a part of an eco-friendly and user-friendly method of control.

This work aimed to evaluate the efficacy of modified atmosphere (MA) enriched with Argon gas as an alternative measure for controllingfour stored dates pests, two from order: Lepidoptera, Ephestia cautella (Walker) & Plodia interpunctella (Hübner) and two from order Coleoptera; Oryzaephilus surinamensis Linnaeus & Stegobium paniceum (L.) and its effect on some enzymes activity of tested insects. Argon gas concentrations of (60, 80 and 100 %) had been tested against the four mentioned insects at different exposure times ranged from 3 to 144 hrs. The results revealed that Lepidopterous were more sensitive to Argon gas than Coleopterous. Also, data indicated that not all tested insects have the same sensitivity to Argon gas. Obtained results indicated that the reduction % of adult emergence increased by increasing exposure duration and or concentration. At the concentration of 100 % Argon, data reported that the larvae of E. cautella were the most susceptible and reached a 100% reduction after 12 hrs. While the adults of O. surinamensis was the most tolerant insect stage to Argon gas where reached 74.60 % reduction after 72 hrs. Exposure of P. interpunctella and O. surinamensis to LT 50 of Argon increased the activity of two defensive enzymes within tested insects, Acid phosphatase, &Carboxlesterases. and decreased the activity of LDH enzyme.

The impact of temperature and some life table parameters of Rhopalosiphum padi (Linnaeus, 1758), were investigated at 18, 20, 22 and 24°C constant temperatures. The development durations decreased as the temperature increased, recorded 8.36, 7.65, 6.8 and 5.19 days at 18, 20, 22 and 24°C, respectively. The temperature threshold for the development of first, second, third and fourth instars and overall nymphal stage were 4.53, 7.96, 10.02, 9.67 and 8.25°C, respectively. The thermal units required for each nymphal instar; first, second, third and fourth and overall nymphal stages were 27.78, 21.28, 16.39, 22.22 and 83.33 day-degrees, respectively. The average adult fecundity was as high as 91.74 and 73.25 offspring at 20 and 22°C, but dropped to 47.66 and 63.45 offspring at 18 and 24°C. However, the average (mx) values per female/day were 2.24, 2.12, 1.93 and 1.01 offspring at 20, 24, 22 and 18°C, respectively. The highest net reproduction rates (R0) were 61.46 and 54.42 at 20 and 22°C, and mean generation time (T) and population doubling time (DT) diminished as temperature increased. The intrinsic rate of increase (rm= 0.3 and 0.25) and the finite rate of increase (λ= 1.36 and 1.29 nymphs/female/day) were greatest at 24 and 22°C, respectively. The results indicated clearly that temperatures from 20 to 24°C were in the favourable range for survival and reproduction of this serious pest.

Waheeb,
H.
Although Egyptian cotton leafworm Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) is native in Africa, it is distributed throughout the world. It is a serious polyphagous insect damaging more than 90 host plants of economic importance. The objective of the current study was to evaluate the disruptive impact of Nerolidol, a Sesquiterpene compound, on the most important parameters of adult performance and reproductive potential of this insect. The newly moulted larvae of 5th (penultimate) or 6th (last) instar larvae fed castor bean leaves previously treated with 7 concentrations of Nerolidol(400, 200, 100, 50, 25, 12.5& 6.25 ppm) for 24 hr. The most important results could be summarized as follows. Nerolidol exhibited an adulticidal activity only at the higher concentrations. Nerolidol exerted an anti-morphogenic activity against adult moths since some malformed adults were produced at the higher concentrations. Regardless the treated larval instar, Nerolidol induced the successfully emerged adults to live remarkably shortened total longevity and oviposition period, but the pre-oviposition period was generally prolonged. Nerolidol exhibited an inhibitory effect on the oviposition efficiency since the oviposition rate was deleteriously regressed, in a dose-dependent course. Nerolidol caused a disturbance of the reproductive capacity since fecundity and fertility were dramatically prohibited. After larval treatment with Nerolidol, the successfully mated adult females laid eggs with a significantly prolonged incubation period, especially at the higher concentration levels.

This study was carried out to study the effect of infested carnation plants (Dianthus caryophyllus L.) by Carnation Thrips, Haplothrips cottei (Vuillet) (Thysanoptera: Thripidae) andBemisia tabaci (Gennadius) on the quantity of annual production of carnation flowers under glasshouse conditions at three locations (governorates), International Garden (Cairo Governorate), El-Orman Garden, (Giza Governorate) and International Garden (Alexandria Governorate) during successive season 2018, 2019. Therefore, this study was divided into three parts, the first part studied population fluctuation of H. cottei andB. tabacion the carnation plants during successive season. The second part studied the effect of infested carnation plants by the two insects on the quantity of annual production of carnation flowers at the three locations. And the third part studied the effect of insect infestation by the two insects on the internal components of carnation plants. Results obtained showed that the infestation by H. cottei reduced the quantity of annual production of carnation flowers after picking more the infestation byB. tabaci compared to control (which non infested by the same insects). Also, results showed that the infestation by H. cottei reduced total sugar and total protein as the infested carnation flowers more than the infestation byB. tabacicompared to control.

Radiation technology is widely used to produce changes in biosystems. The goal of this work is to determine the variation induced in male parents and F1 Ceratitiis capitata when gamma-irradiated as pupae using substerilising doses (50 and 70 Gy and sterilising dose 90 Gy. Biological studies showed that the percent adult emergence of irradiated pupae decreased as the dose increased and also the percent egg hatchability decreased as the dose increased, also percent pupation and percent emergence of F1 decreased as the dose increased. Comparing DNA (using RAPD-PCR) of untreated adults, adults irradiated with sterilising dose of 90 Gy and parents irradiated with substerile dose (50 and 70 Gy) and their resultant F1. The results revealed that some extra bands appeared and others disappeared, as a result of irradiation. The appearance of extra bands may be due to the repair mechanism of the irradiation damaged DNA. The banding patterns obtained and the dendrograms drawn on the basis of presence and absence of bands revealed that irradiation of parents with 50 and 70 Gy and their F1 are different from the unirradiated pupae It was concluded that the sterile male technique could be used as a benefit tool in controlling Ceratitiis capitata.

Four native isolates of entomopathogenic fungi (EPF) Beauveria bassiana (B1and B2), Metarhizium anisopliae (M1 and M2 ) were isolated and evaluated against wheat aphid, Schizaphis graminum (Rondani). Three concentrations of spores suspension from each of the four fungal isolates (1×106, 1×107 and 1×108conidia) were used against adult aphid (one day old). The results showed that (B1) was the most effective according to LC50. Whereas, when testing the toxicity of crude metabolites of fungal isolates in four concentrations for each isolate, it was found that the highest effective toxin was (M1) followed by (B1), (M2) and (B2). Scanning electron microscope photographs (SEM) showed the mode of action of entomopathogenic fungi and its ability to colonize and how it infects aphid.

Occurrence of Ootheca of Mantids and Their Natural Enemies in Citrus Orchards in Sohag, Egypt
Hosam,
El-Gepaly
The giant African mantis, Sphodromantis viridis Forsskål, 1775 (Mantodea: Mantidae) was the most observed species of praying mantis in citrus orchards at Sohag Governorate, Egypt during 2017 and 2018 years. Besides, the Egyptian praying mantis, Miomantis paykulii (Stal, 1871) and the European mantis, Mantis religiosa, were observed in rare numbers. About 530 and 575 oothecae of mantis were collected in 2017 and 2018 respectively from about 46 hectares of citrus. The incubation of these oothecae resulted in complex fauna consisting of four hymenopteran parasitoids, Podagrion sp. (Torymidae: Hymenoptera), formicidae & Eupelmidae (Hymenoptera) and other hymenopteran specie, also four spider predators and Scolothrips sp. were found. Among the collected oothecae, totals of 28 and 25 oothecae hatched to mantis nymphs producing totals of 1536 and 1318 nymph/year for 2017 and 2018 years respectively. Podagrion sp. was the most common parasitic specie and the highest mean number of parasitoids/ootheca was in November with an average of 88 and 116 parasitoid/ootheca for 2107 and 2018 years respectively. Spiders were the most frequent among the oothecae fauna, as the spiders have emerged from the oothecae in the juvenile phase or adult. Incomplete parasitism was calculated after dissection of oothecae, the highest parasitism rate of oothecae was in May and March for 2017 and 2018 years, while the lowest rate was recorded in September for both years.

In the present study two different cell cultures, derived from human skin melanocyte (HFB4) and Human Lung Fibroblast (ATCC) (WI-38) were used to examine. Three insects from two orders; Lepidoptera: Ephestia kueniella and Coleoptera: Trogoderma granarium & Tribolium castaneum were reared to study. Lung cells were the most sensitive than melanocyte. T. castaneum was recorded the most cytotoxicity than other insects in general. T. castaneum was the higher toxic in melano cells while T. granarium was the higher toxic in lung cells. However, morphological changes in treated cells were observed compared to non treated cells. Our results indicate that grains and its products infested with stored grain insects caused toxic and death to cells which it exposure.

Effectiveness of Ozone Gas Against the Potato Tuber Moth (Phthorimaea Operculella) Infested Stored Potato Tubers
Nasr,
H.
The effect of ozone against immature stages of the potato tuber moth (PTM) Phthorimaea operculella was investigated. The immatures (Eggs, the newly hatched larvae, 12days old larvae, and pupae) were exposed to ozone concentrations using two procedures. Thirty of isolated stages (first procedure of exposure) and 5 of infested potato tubers contain a separate stage of PTM (the second one) were exposed toozone concentrations 50, 100, 200, 400, 600, 800 and 1000 ppm in a combination of different exposure times 2, 4, 6 and 8 hours. All results indicated that mortality percent of all insect stages increased by increasing the concentration and exposure time. The effect of ozone concentrations was higher on the isolated numbers of immature stages in the first procedure of exposure than that within potato tubers in the second one. The newly hatched larvae in both procedures were the most sensitive stage to ozone, it completely killed when exposed for 8hrs at 50 and 200 ppm in the first procedure and second procedure, respectively. While the elder larval stage was the least sensitive one. At the highest concentration and the longest exposure time (8hrs), larval mortality was 82.2 and 68.5 % in the two procedures, respectively. Also, sprouting of potato seeds was enhanced when treated with ozone concentrations compared with untreated seeds.

Many aphidsˈ species are considered as the most serious insectsˈ pests that attack the wheat plants in Egypt, from planting date up to the harvesting time of the crop. Therefore, the present field study was carried out to estimate the population density of the wheat aphidsˈ species, the related parasitoids (either the primary or the secondary ones) and also the common predators of familyCoccinellidae, which occurred on the wheat plants, during the two successive seasons 2017/2018 and 2018/2019, in Qalubia Governorate. The natural positive and negative relationships that were existed between the wheat aphidsˈ species and these common natural enemies were also studied. However, it is necessary for effective successful biological control programs to study the natural enemies’ activity, to evaluate the impact degree on the pests’ populations, and also to detect the need for any additional control measures to be applied. So, the obtained results revealed that the occurrence periods of the aphids’ species on the wheat plants were extended during the whole period of the wheat plantation (i.e., from the period extended from December to April), of the two studied seasons, 2017/2018 and 2018/2019. The total numbers of the wingless individuals were higher than those of the winged adults on the wheat plants. In addition, the total number of the aphids’ population in the second season (2018/2019) was higher as compared with that recorded in the first one (2017/2018) of the study. Theaphidsˈ parasitoids immediately appeared in the wheat fields after the beginning of the aphidsˈ infestation, where the percentages of the aphidsˈ species parasitism were relatively lower in the two growing studied seasons. The primary parasitoid Aphidius colemani Viereck was the predominant parasitoid species recorded attacking the aphidsˈ species in the wheat fields, in comparison with the other recorded primary parasitoids. Where, the recorded primary parasitoids (Hymenoptera: Aphidiidae) were arranged according to the mean percentages of their occurrence to each others for the two seasons of the study as follows: A. colemani (52.03% (0.00-56.66%)) > Ephedrus sp. (mostly E. persicae Froggatt) (33.94% (0.00-54.55%)) > Lysiphlebus sp. (10.41% (0.00-18.18%)) >Diaeretiella rapae Mclntosh (3.62% (0.00-14.28%)). As for the secondary parasitoidsˈ species, their total numbers were higher in the first season (2017/2018) in comparing with the second one (2018/2019) and they were also higher in their total numbers than those of the primary one, in the two investigated seasons. The mean percentages of the occurrence of the secondary parasitoids (the hyperparasitoids) species to each other for the two seasons of the study were; Dendrocerus spp. (Megaspilidae) (65.60%) > pteromalids spp. (Pteromalidae) (34.40%) and the period of their occurrence extended from January to April, in 2017/2018 and 2018/2019 seasons. Moreover, the obtained results revealed that the mean total numbers of adults of the two common recorded predatoryˈ species of family Coccinellidae, of the two seasons, were; Coccinella undecimpunctata L. (162.50(0-103 adults)) > Hippoddamia convergens Geur. (98.00 (0-87 adults)). The period of predatoryˈ species occurrence extended from January to April, in the two seasons (i.e., the period of the occurrence the covered the four months of the wheat plantation). As a result, the natural sequence role of the two biocontrol agents; the primary parasitoidsˈ species and the two major ladybirds’ predators (C. undecimpunctata and H. convergens), must be continuously encouraged and developed) in the wheat fields by maintaining the suitable safe conditions to do such important natural role. Also, in the view of the natural occurrence of the previous biocontrol agents, they can be massed reared in the laboratory and released for controlling the aphidsˈ species on the wheat plants or the other related plants that are subjected to the aphidsˈ attack. They can be applied side by side with the other available safe control methods, in the frame of Integrated Pest Management (I.P.M.) programs, for protecting man heath and the surrounding environment from pollution.

Insects include almost 60% of the described eukaryotic animals worldwide. However, the morphological measurements and assessment of the effects of isolation and habitat still lack many insect groups. The current study aimed to compare the morphometric measurements of dissimilar populations of darkling beetles “Pimelia nilotica” in Egypt. A variable comparison of morphometric variations was taken by a threaded micrometer for six different eco-geographical regions from Egypt fall under the Western Mediterranean Coastal Desert, Western Desert Oases, El-Faiyum Depression, the Eastern Desert, Nile Delta, and South Sinai. Twenty-one morphometric measurements were taken in the currents study. Traits best reminiscent of the excellence of populations were distinguished by cluster analysis, and also by the principal component analysis. The primary and second discriminants scores (score 1 and score 2) recorded 76.4% and 23.8%, respectively, of the full variation in samples. Multiple discriminant analysis disclosed clear morphometric differences between Western Desert, Eastern Desert, El-Faiyum Depression, and South Sinai populations. Traits clarifying the maximum of the changeability among populations were those associated with the morphological estimations.

Amro
Taha
This study was conducted with the aim of assessing the quality of some African honey types and ruling on their suitability for export. Numbers of 22 honey samples were analyzed from five African countries, namely Egypt, Libya, Algeria, Cameroon, and Zimbabwe. Results showed that the total sugar content of honey samples varies between (51.59 %, sample 10), and (75.27 %, sample 19). Honey samples from Zimbabwe had significantly the highest value of fructose (39.33±0.19 %) followed by Libyan honey (38.91±0.52 %). On the other hand, sample (1) from Egypt gave the least value of fructose sugar content represented (26.73±0.42 %). All the honey samples from Algeria, Cameroon, and Zimbabwe did not exceed the standard limit of sucrose content (5 %) indicates that the bees were not artificially fed with sugar. Samples (17 and 18) from Zimbabwe were significantly the inferior of sucrose sugar content with averages (0.58±0.04 % and 0.58±0.01 %), respectively. In addition, sample (9) from Algeria was significantly superior of all honey samples in diastase number giving (35.2±0.46 µ/g). It is clear that two honey samples from each Algeria, Cameroon, and Zimbabwe were in an acceptable range of diastase number represented (35.2, 18.2 µ/g), (26.8, 17.52 µ/g) and (14.0, 13.9 µ/g), respectively. On the other hand, diastase number DN of all honey samples from Egypt and Libya was below the proposed standard limit. Libyan honey samples had significantly the highest HMF content ranged from (418.9±5.77 to 684.0±2.30 mg/kg). On the contrary, Algerian honey samples had the least significantly HMF content of all tested samples with range (5.10±0.57 to 19.9±0.26 mg/kg). For proline amino acid, all the honey samples from Cameroon, Libya, and Algeria contain higher proline content than the standard limit. The mean flavonoid content of the African honey samples was ranged from (0.02± 0.005 g/100g, sample 1) to (0.31±0.005 g/100g, samples 4 and 16), respectively. The results suggested that measuring flavonoids levels and proline amino acid could be used to study honey’s floral and geographical origins.

Peach fruit fly, Bactrocera zonata (Fam: Tephritidae, or: Diptera), is a quarantine insect-pest that infests various commercial fruit and vegetable crops in Egypt. Almost all the monitoring and control strategies of this flydepend on the use of the para-pheromone methyl eugenol (ME) as a sex attractant of male flies. Therefore, the current study aimed to investigate the potential use of the essential oil of berries of cubeb pepper (tailed pepper) (CEO), Piper cubeba (Fam: Piperaceae) as an attractant for B.zonata flies. CEO was extracted using the hydro-distillation scavenging apparatus from cubeb berries and chemically analyzed by GC-MS. The CEO was assayed in the attraction of B. zonata flies compared with the recommended dose of para-pheromone ME. Results showed that ME and the CEOat the different concentrations had attracted male flies and no females. Remarkably, there were no significant differences between ME and crude CEO in attracting the male flies. The GC-MS results revealed about 29 major constituents of CEO; the eugenol was the major constituent (45.88%)of the CEO, followed by 3-methyl-pentane (15.36%), methyl-cyclopentane (9.198%), and methyl eugenol (6.093%). These findings explaine the effective role of CEO as a male attractant of B. zonata and it could be used as an alternative to the ME, which would conserve a huge amount of money spent on buying the chemical ME.

Red pumpkin beetle (RPB) is one of the most notorious insect pest and a serious threat to all cucurbits. Five cultivars of cucurbits, Cucumis sativus L., Momordica charantia L., Luffa acutangula L., Cucurbita pepo L. and Citrullus lanatus (Thunb.) were tested for feeding preferences of RPB for two years. All the cultivars of cucurbits were highly infested in their foliage and flowers resulting in a decline of yield. High RPB infestation was recorded in 2015 compared to 2014. The average population per ten leaves was high in pumpkin and cucumber but low in bitter gourd. Overall data showed that pumpkin was highly preferred cultivar followed by cucumber, watermelon, ridge gourd and bitter gourd. In no choice test, the highest reduction in the leaf area was recorded in pumpkin followed by ridge gourd, cucumber, bitter gourd and water melon. Therefore, appropriate control measure may be taken into consideration as per susceptibility of the host to reduce RPB infestation. Our studies have shown that bitter gourd was the least preferred cultivar, thus, planting bitter gourd as companion crop as borders or in mix cultivation could safeguard other cucurbits.

Biological characteristics of the predator Chrysoperla carnea, aphid lion were studied in the laboratory at a temperature of. 25±1°C, 70±5% relative humidity, and 16:8 h of daily light / dark periods. two different preys were tested as hosts for C. carnea larvae. The predator larvae were fed on newly emerged larvae of pink bollworm, Pectinophera gossypiella,and adult members of Aphis craccivora, Cowpea aphid (2-3 days old), The results showed that the duration of larval and pupal period of predator was observed differences which recorded 8.46± 0.82 and 6.92± 0.86 days, respectively, when the predator larvae fed on PBW larvae, while recorded 8.25± 0.96 and 6± 0.15 days, respectively, when the predator larvae fed on adult aphids. The larval survival percentage was 88.1% and 90.2% respectively, while the emergence of the adult was 87.4% and 94.7% respectively, Data showed the incubation period of eggs was similar in two treatments, the duration of C. carnea females had higher than the duration of males. The percent of egg hatchability recorded a higher value 95.87% when the predator larvae fed on adult aphids and recorded 91.51% when its fed on PBW larvae.

Abdelhalim,
Khalil
Faba bean is an important position between leguminous food crops in Egypt. A piercing-sucking pest associated with broad bean plants causes serious damage, directly by sucking plant juices or indirectly as the aphid insects are vectors to plant diseases. A field experiment was conducted at Wadi Elmalak, Ismailia Governorate, Egypt in winter growing seasons 2018/2019 and 2019/2020. To evaluate the population fluctuation of some piercing-sucking pests and the common natural enemies and relation to weather factors on broad bean plants. Results indicated that the important piercing-sucking pests, pea aphid, Acyrthosiphon pisum (Harris) were the most dominant, followed by Aphis craccivora Koch, while green peach aphid, Myzus persicae (Sulzer), Thrips tabaci Lind. and Jassid, Empoasca discipiens Poali were found in low densities throughout the two seasons. The eleven spotted lady beetle, Coccinella undecimpunctata L., green lacewing, Chrysoperla carnea (Stephens), and seven-spotted lady beetle, Coccinella septempunctata L. are the most important predators which associated with the sucking insect pests on faba bean. The population fluctuation of piercing-sucking pests and associated predators were higher in the first season than in the second season. The pea aphid, A. pisum started with attacks broad bean in the second week of November and reached it has two peaks early January and in mid-May in the two successive years. The relationship between both of the population of piercing-sucking pests and associated predators and weather factors were studied. The loss in seed yield in the two successive seasons was evaluated all together being (330.0 kg. /fed). The avoidable losses in seeds yield were (19.18% per fed.) during two seasons

The present study was conducted out to investigate the effect of foliar application of five pea cultivars (Entesar 1, Goara, Line 1, Line 11 and Line 14) with salicylic acid (SA) on infestation by Aphis craccivora (Koch.), Thrips tabaci Lindeman and Liriomyza trifolii Burg. during 2018/2019 and 2019/2020 winter seasons at Sohag Governorate. Also, the effect of SA application on the growth, yield, and some yield components of pea was included. Data revealed that the foliar application with SA at 200ppm and 100ppm reduced A. craccivora, T. tabaci, and L. trifolii (mines) infestations by about 50% and 30%, respectively, compared with control in both seasons. Also, plant height, the number of pods/ plant, weight, total green pods yield/ plant, and total yield/ Feddan were increased by the two SA treatments comparing to control in both seasons. The five pea cultivars varied significantly in their susceptibility to the three studied pests and in horticultural characters in both seasons. The interaction between pea varieties and SA treatments was discussed.
