This study was carried out to study effect of infested Carnation flowers (<em>Dianthus</em> <em>caryophyllus</em> L.) by Carnation thrips, <em>Haplothrips cottei</em> (Vuillet) (Thysanoptera: Thripidae) and<em>Tetranychus urticae </em>Koch (Acari: Tetranychidae) on the vase life period of Carnation flowers under glasshouse conditions at two locations (governorates), International Garden (Cairo Governorate) and El-Orman Garden, (Giza Governorate) during successive seasons 2018. This is because the vase life period is very important parameter in cut flowers. And there are many factors affected on the vase life period. Therefore this study divided into two parts, first part studied effect of infested Carnation flowers by <em>H. cottei</em> and<em>T. urticae </em>on the vase life period of Carnation flowers after picking. Second part studied effect of infested Carnation flowers by the same pests on the internal components of these flowers which correlated with vase life period such as total sugar and total protein. Results obtained showed that the infestation by <em>H. cottei</em> reduced the vase life period of carnation flowers after picking more the infestation by<em>T. urticae</em> compared to control (which non infested by the same pests). Also results showed that the infestation by<em> H. cottei</em> reduced total suger and total protein at the infested Carnation flowers more than the infestation by<em>T. urticae </em>compared to control. Lastly, results obtained showed that the infestation by <em>H. cottei</em> and<em>T. urticae </em>changed the number and arrange of the protein banding patterns (amino acids) of infested Carnation flowers petals compared to control.

Various type of sticky traps is frequently used for monitoring the sucking pests like jassid, aphid, whitefly, and thrips. Light traps and pheromones traps are species specific and commonly used for capturing the moths such as <em>Spodoptera litura, Helicoverpa armigera </em>and<em> Leucinodes orbonalis. </em>The sucking and chewing are very destructive pests of various crops such as cotton, cabbage, brinjal, okra, tomato and onion all over the world, Insect pests are controlled by various methods but insecticides are commonly used method to control these pests. A filed experiment was conducted to determine the attraction of insect pests to different sticky traps like red, blue, yellow, orange, pale yellow-green and white while light and pheromone traps also installed to capture the <em>Spodoptera litura, Helicoverpa armigera </em>and<em> Leucinodes orbonalis</em> moths during 2019. The study showed that that yellow sticky traps were the most effective for monitoring and managing thrips and whiteflies in cotton crops. In brinjal crop, the highest adult population of thrips, whitefly, jassid, and aphid was 139, 13, 29 and 13 per card, respectively were recorded on green traps. Light traps and pheromone traps were proved effective control against chewing insect pests especially <em>Spodoptera litura</em> followed by <em>Helicoverpa armigera </em>and <em>Leucinodes orbonalis.</em> The current study concluded that eco-friendly and natural approaches such as use of traps are helpful in pest management on agricultural crops.

Sucking insects are the most serious insect pests in wheat crops; the harmful effect of aphid in wheat plants is due to sucking of plant sap, honeydew excretion and causing many diseases by transport of plant viruses. The experiment was carried out at Sakha Agric. Res. Station farm during 2017-2018 on wheat Giza 171 growing season. The insecticide used is Imidacloprid (Nofedor 600 FS.) The present study was designed to evaluate comparative efficacy of imidacloprid as seed dressing formulation against sucking insects (<em>Schizaphis graminum</em>, <em>Nezara viridula</em>, <em>Empoasca spp.</em>) as well as their predators; <em>Chrysoperla carena, Labidura riparia, Scymunus spp</em>. and true spiders in two types of wheat sowing (Drill and Broadcast) in the wheat crop field. The results according to analysis of variance showed that there was a significant variation among the insect’s reduction in all-season periods as a result of treatment of the wheat seeds before sowing with imidacloprid in the Broadcast and drill sowing. Whereas there is no significant effect of the treatment when comparing <em>S. graminum </em>in different sowing methods, also there was a non-significant effect of the treatment on <em>S. graminum </em>in broadcast method versus <em>N. viridula</em>, <em>Empoasca spp</em>. and predators. While, the number of seeds/spikes, Weight of 100 seeds (gm) and the Germination increasing % in Broadcast sowing were more than that in Drill sowing by 1.31,1.11 and 1.11 respectively. Thus, it could be concluded that the broadcast sowing is suitable economically for farmers than drill sowing methods when using imidacloprid as seed dressing before cultivation for sucking insect control as well as its predators.

Topical application of a single dose (10µl/tick or egg batch) of different concentrations of abamectin (an avermectin) has lethal and biological effects on the engorged mated adult female, immatures and egg of <em>Argas (Persicargas) arboreus</em> that induced 100% mortality at 25,15 and 10 ppm, respectively. Abamectin treatment at lower concentrations of 1-10 ppm interfered with the female reproduction, nymphal and egg development.<br /> Abamectin topical (3-10 ppm) application on mated engorged adult female <em>A. (P.) arboreus</em> at different intervals of its reproductive cycle reduced fecundity and fertility of the female, prolonged its preoviposition, oviposition and the egg incubation periods. The effects were most prominent during vitellogenesis and the least at the start of oviposition.<br /> Abamectin treatment of the newly moulted fed 2<sup>nd</sup> nymphal instar, delayed its moulting and of the resulted 3<sup>rd</sup> instar and reduced adult emergence. The treatment caused paralysis and various deformities (15.6-28.6%) as missing legs at the coxal level, changes in colour and failure to moult or to detach the old exuvia in the resulted 3<sup>rd</sup> nymphal instar.<br /> Egg batch treatment by dipping the freshly deposited eggs for 20 seconds in an aqueous solution of 1-5 ppm abamectin was more effective in reducing normal hatching, increasing unhatching and total inhibition of egg development than topical treatment. However, both methods of treatment similarly prolonged the egg incubation periods and caused abnormal hatching, malformations, and anomalies in the eggs and embryos

The population dynamics and distribution of <em>Chrysoperla carnea</em> and <em>Coccinella septempunctata</em> collected monthly from eight alfalfa (<em>Medicago sativa </em>L.) fields in two oases of Western Desert, Egypt was studied during two successive years. <em>Chrysoperla carnea</em> was collected by a net and represented 5652 individuals including 3021 and 2631 from Farafra and Baharyia Oases respectively. In Farafra Oasis in Shimenara location was richer than the other site and recorded 35.91% of collected individuals and the Grad was found to be a poor location and represented by 13.7 %. Baharyia Oasis site Kasaa 3 was high in richness and contained 32.12% of collected individuals, Al-Gafara location was the poor location and represented 14.63 %. The fluctuation of <em>C. carnea</em> was amplified in autumn, spring and sharply declined during winter and summer. A total number of 3672<em> C. </em><em>septempunctata</em> was collected, including 1986 from Farafra Oasis and 1686 from Baharyia Oasis and represented by 54.1% and 45.9%, respectively. The insect population showed a clear variation in number in both the locations, we found that the count increased in the second year representing 64% of the total insects collected. At the same time, in the first year Farafra Oasis was richer while Bahariya Oasis increased slightly in the second year. The increase of<em>C. septempunctata</em>in autumn was repeated in spring and sharply decreased during winter and summer months. The maximum numbers were collected in the months of February, March, and April and the highest count of both the years (2013 and 2014) was in March.

An experiment was carried out to evaluate the effect of using different host plants Castor bean<strong>, </strong>Clover, Cabbage, Broad bean, Sugar beet, and Cotton as foods for Spodoptera<em> littoralis</em> (Boisd.) larvae on certain biological aspects of the insect. The study was achieved under laboratory conditions of (25 ± 1°C) and 75 ± 5 % R.H. for obtained results and statistical analysis cleared that the developmental stages, fecundity, and life parameters were affected by the different hosts whereas the shortest larval duration (18 ± 0 days) was recorded for larvae fed on clover and the longer (25.2 ± 0.37 days) resulted when larvae were offered sugar beet. The pupation percentages on sugar beet leaves were lowest (58.4 ± 2.38 %) and highest pupation percentages were (78.4 ± 1.08 %) when larvae fed on clover leaves. Moreover, adult emergence Percentage was (98 ± 0.45 %) in both clover and broad bean (95.58 ± 0.61 %) on sugar beet. The moths produced from larvae fed on broad bean laid the highest number of eggs (1915 and 1847 eggs per female) in both generations, respectively and the least numbers of eggs deposited were (1081 and 994 eggs/female) on cabbagein the two generations, respectively.

The biological aspects and life table parameters of the spider mite, <em>Tetranychus urticae </em>Koch were studied under laboratory conditions on two kinds of host plants, tomato leaves and cucumber leaves. The study showed that the incubation period, the total immature stages, life cycle and generation of <em>T. urticae </em>on tomato leaves were higher than them on cucumber leaves. The life cycle was 13.58 and 9.52 days on tomato leaves and cucumber leaves, respectively. The generation period was 15.91 and 11.19 days on tomato leaves and cucumber leaves, respectively. On the other hand, longevity and life span of <em>T. urticae </em>were higher on cucumber than on tomato. Longevity was 15.33 and 19.97 days on tomato leaves and cucumber leaves, respectively. The life span was 28.91 and 29.49 days on tomato leaves and cucumber leaves, respectively. Also, the daily main number of laid eggs was higher on cucumber, 5.36, than on tomato, 4.71. Also, the results demonstrated that the population of <em>T. urticae</em> had the ability to multiply about 1.91 and 2.53 on tomato and cucumber leaves, respectively.

The armyworm, <em>Spodoptera litura</em> Fab. (Lepidoptera: Noctuidae) is an economically important insect pest of vegetables, ornamentals and other agricultural crops. Synthetic insecticides have remained primary means for the management of <em>S. litura </em>than any other management tool. We tested the effectiveness of some insecticides against different larval instars of <em>S. litura</em> in laboratory as well as in field on the prevailing instars in two fodder crops lucern/alfalfa,<em> Medicago sativa </em>L. and jantar/sesbania,<em> Sesbania sesban</em> L. In the laboratory, emamectin benzoate provided the most control 69-91% followed by lufenuron 70-85% of all larval instars after 48 hours of application. In the lucern field, emamectin benzoate reduced the larval population of <em>S. litura</em> up to 79.32% and with the application of lufenuron 73.55% reduction occurred. Similarly, in jantar crop, lufenuron and emamectin benzoate proved to be more toxic against <em>S. litura</em> population. The abundance of ladybird beetle, <em>Coccinella septempunctata</em> L. (Coleoptera; Coccinellidae), honeybee, <em>Apis mellifera</em> L. (Hymenoptera; Apidae) and green lacewing, <em>Chrysoperla carnea </em>Stephen (Neuroptera; Chrysopidae) were found higher in emamectin and lufenuron treated plots compared to methoxyfenozide and chlorpyrifos. These results indicate that new chemistry insecticides; emamectin benzoate and lufenuron have a potential for the management of <em>S. litura</em> and are relatively safer for beneficial insects as compared to conventional insecticides, methoxyfenozide, and chlorpyrifos.

A survey of spider community composition and diversity associated with quinoa plants was carried out at Fayoum governorate, Ibshway region, Aboksa village from September to April during two winter seasons, 2016/2017 and 2017-2018. Pitfall traps were used. Numbers of collected spiders were pooled and analyzed for species diversity using Shannon-Wiener Index, evenness, Simpson Index and Sørensen Quotient of Similarity. A total of 399 spiders grouped in 11 families belonging to 21 genera and more than 22 species. First season received 124 individuals belonged to 20 genera, 20 species of 8 families, while second season received 275 individuals belonged to 21 genera, 21 species of 10 families. Four families contained 92.5% of the total collected spiders; they are Lycosidae, Linyphiidae, Theridiidae and Gnaphosidae. Lycosidae was the most abundant family (55.99%) followed by Linyphiidae (25.81%). The other remaining families represented 18.75% of the total catch. Guild structure analysis revealed seven feeding guilds namely, stalker, ground runner, ambusher, space weaver, wandering sheet spiders, sensing and space web. Guild structure varied, in the first season, Wandering sheet and ground running representing 12.53 and 12.78 % of the total spiders while the second season, wandering sheet and ground running representing 12.28 and 48.12% of the total spiders and had the highest species richness.

This work was carried out at the apiary of Bee Research Department, Quanter branch, Qaluobia governorate during the period from December 2016 to April 2017 to evaluate the effect of feeding honeybee colonies with ten diets as pollen substitutes on diets consumption rates, brood rearing, pollen and honey storage activities. Six Proteinaceous materials were used as follows; defatted soybean flour, chickpea flour, maize flour, pea flour, wheat germ and dried brewer's yeast, were mixed with sugar powder, bee honey and water in different proportions forming ten diets taking letters from A to J. The obtained results revealed that colonies were fed on Diet H (chickpea flour + wheat germ + dried brewer's yeast) produced the highest average of biological activities, which were 105.54 g, 363.75 inch², 134.83 inch² and 404.08 inch²/colony for diet consumption, sealed workers brood area, stored pollen area and stored honey area, respectively. On the contrary, the colonies fed on Diet C (pea flour + defatted soybean flour + dried brewer's yeast) produced the lowest average of biological activities, which were 77.0 g., 235.1 inch², 75.43 inch² and 258.39 inch²/colony for diet consumption, sealed workers brood area, stored pollen area and stored honey area, respectively. There were a direct relationship between diets consumption and each of brood rearing, pollen and honey storage activities during winter season compared with control colonies, which showed a noticeable decrease in all of these biological activities.

Soybeans stand out among the main crops of world economic interest, Brazil being one of the main producing and exporting countries. Thus, this work aimed to evaluate the efficiency of insecticides used alone and with the addition of adjuvant formulas based on orange oil and nanoparticulated sulfur (Oro Solve<sup>®</sup>) in the control of the neotropical brown stink bug in soybean. The experiment was carried out at the Experimental Farm of the State University of Maringá – UEM, located in the city of Umuarama – PR. Samples were collected and periodically evaluated at predetermined intervals: an analysis prior to application and analysis was performed at 1, 3, 5 and 10 days after application. On the 10th day after the beginning of the experiment, a new application was performed, with subsequent evaluations 1 and 3 days after reapplication. In the evaluations, the number of stink bugs found per sampling and the efficiency of control in each treatment was noted. It was evaluated by manual harvesting of 1.0 meters in three lines of the useful area of each plot, with a posterior trail, using a stationary trail. After weighment, the grains or values were transformed to kg.ha<sup>-1</sup>, using the correction of recovery for the water content of 13%. Neotropical brown stink bug occurrence data, insecticide and mixtures evaluation, as well as soybean yield, were subjected to analysis of variance by the F test, and the means compared by the Duncan and Tukey test (P≤0.05), respectively. The insecticides based on acephate (Perito<sup>®</sup>), imidacloprid + bifenthrin (Galil<sup>®</sup>) and bifenthrin + carbosulfan (Talisman<sup>®</sup>) in addition to Oro Solve<sup>®</sup> were found to show greater bedbug control efficiency. There was a greater extension of the effective control period in the treatments that had adjuvant addition. The application to the tests that were sprayed with insecticides in addition to Oro Solve<sup>®</sup>, and the insecticides used alone were used, but they all differed from the control and the percentage increase was always higher in the tests containing the mixture with Oro Solve<sup>®</sup>.

In Egypt, The Nabq trees (Z<em>iziphus spina</em>-<em>christi</em> (L.)), (Family: Rhamnaceae) are considered as an important host plant having high medical economic value. These trees are attacked by many insect pests, where they seemed to be the sole recorded host plant of the monophagous fruit fly species; the <em>Zizyphus</em> fruit fly <em>Carpomyia incompleta</em> Becker (Diptera: Tephritidae) from the viable literatures A field study was performed to survey the population dynamics of the pest in the three different districts (Shandaweel, Gohena, and Balasfora) in Sohag Governorate, during two periods at the beginning of the fruit maturation from March to June (in the first period) and from September to November (in the second period), in the two successive season 2016 and 2017. The obtained results indicated that the Z<em>iziphus </em>fruit fly was found to be parasitized by the common parasitoid<em> Psyttalia </em>(<em>Opius</em>)<em> concolor</em> Sźepl. (Hymenoptera: Braconidae). However, the general sex ratios obtained between (the pest and the commonly recorded parasitoid), clearly indicated these ratios were greatly towards females than males in the case of both the pest and the parasitoid. Where the occurrence of the parasitoid was related was that of its insect host during two periods of the beginning of the fruit maturation. Magnifying this natural role of the parasitoid <em>P. concolor</em> becomes necessary in order to encourage this beneficial agent to do its role and decrease the degree of infestation by the <em>Zizphus</em> trees or other fruit trees that may be subjected to the <em>Zizphus</em> fruit fly attack to an acceptable level. Moreover, this parasitoid could be laboratory mass-reared and released against the pest on the <em>Zizphus</em> trees or other fruit trees that are subjected to attack by the other common fruit flies and must be taken into consideration when applying I.P.M. programs (including the use of the biological control techniques). So, the Z<em>iziphus </em>trees are considered as a suitable host plant acting as a natural resource or reservoir for the parasitoid <em>P. concolor </em>that attacks the Z<em>iziphus</em>fruit fly.

The present work was conducted to study the population dynamics of citrus leafminer (CLM) and its associated parasitoids on mandarin trees during two successive years of 2013-14 & 2014-15 all in relation to climatic factors [temperature and relative humidity (R. H.)]. The citrus leafminer larval population had 6 peaks of abundance on mandarin trees in each studied year. The higher population peaks of the pest were noticed during two main periods. The first period was in late May and the second period observed in late August and the middle of September. Generally, springtime is considered the most abundant season for <em>Phyllocnistis citrella</em> infestation followed by either summer or autumn seasons. In winter, there is a complete absence of CLM infestation. There is a positive relationship between CLM population abundance and both temperature and R.H.%. The associated parasitoids <em>Semielacher petiolatus</em> (Girault) and <em>Cirrospilus ingenuus</em> (Gahan) had five peaks of abundance during each studied year. The highest parasitism was 42.5% at the beginning of August in 2013-14 and 19.2% in the middle of September in 2014-15. The effect of a combination of parasitoids and climatic factors on CLM population was presented as explained variance (E.V.) which was 36.9 % in the first and 34.7% in the second studied year.

Quality of mulberry varieties is affected the cocoon production. Selection of the best variety for rearing is primary key for successful rearing. Five mulberry varieties were investigated intend <em>Morus alba</em> Linn. Var. Kokuso-27(M<sub>1</sub>), <em>Morus alba</em> Linn. Var. Kaeryang- Bbong (M<sub>2</sub>), <em>Morus alba</em> Linn. Var. Canava-2 (M<sub>3</sub>), <em>Morus alba</em> Linn. Var. Ardnyl (M<sub>4</sub>) and <em>Morus alba</em> Linn. Var. Suisfen (M<sub>5</sub>). Characters of larval weight during third, fourth and fifth instars, growth rate, consumed food, approximate weight of food digested (AD), approximate digestibility (AD%), efficiency of conversion of ingested food to body substance (ECI), efficiency of conversion of food digested to body matter (ECD) of fourth and fifth instars, consumed food and fresh cocoon yield per 1000 larvae and leaf /cocoon ratio were investigated for all varieties under study. The results revealed that M<sub>1</sub> and M<sub>5</sub> have better mean values for larval weight during third, fourth and fifth instars, growth rate, consumed food, efficiency of conversion of ingested food to body substance (ECI) and efficiency of conversion of food digested to body matter (ECD) of fourth and fifth instars. As well as, varieties of M<sub>1</sub> and M<sub>5</sub> were best for approximate weight of food digested (AD), approximate digestibility (AD%) for fourth and fifth instars, leaf/cocoon ratio because of it earned the lowest average.
