The efficiency of chitin synthesis inhibitor (Lufenuron), ethanolic and acetonic extracts of rice bran (Oryza sativa) were evaluated against Musca domestica eggs by direct application using topical, dipping technique and by treating vitellogenic females by both compounds.
Treatment of females with different concentrations of both compounds significantly reduce egg hatchability and the effect is dose dependent. The inhibition of egg hatching increased with increase in concentration of the compound.
Direct application of both compounds to newly laid eggs (0-15 min) of Musca domestica proved to be more effective in reducing egg hatchability especially when using dipping technique. Percentage total inhibition reached 93.04±0.57 at 3 ppm for Lufenuron and 100% total inhibition at 200 ppm of acetonic extract of rice bran (Oryza sativa). This data confirm the efficiency of growth regulator derived from Oryza sativa straw and chitin synthesis inhibitor (Lufenuron). The results indicated that the acetonic extract of rice bran is significantly effective in preventing hatching than that of ethanolic extract. This is explained that the less polar the extract (acetonic) of rice bran, the more its effectiveness against eggs.

Methanolic extracts of leaves and seeds from, Tribulus terrestris(Zygophyllaceae) was tested against 3rd instar larvae and adults of mosquito, Anopheles arabiensisunder laboratory condition. The seeds extract showed high insecticidal activity at all concentrations compared to the leaves extract and the Lc50 was 36.5 and 123.1ppm for seeds and leaves extract, respectively. All extracts exhibited remarkable effects on the fecundity, fertility and sterility index of adult females resulted from treated larvae, but the seeds extract was more effective than leaves extract. The repellent action of the present plant extracts varied depending on the plant parts and the dose of extract. The seeds extract was more effective in exhibiting the repellent action (100%) against the mosquito tested as compared with the leaves extract (79.5%) at the dose 1.0 and 2.0mg/cm2, respectively. The seeds extract showed the same repellency percent (100%) of commercial formulation, N. N. diethyl toulamide (DEET) but at the lower dose (1.0mg/cm2).The extracts in this study showed strong larvicidal, pupicidal, adulticidal, ovicidal, repellency and biting deterrence and these extracts may be used for further integrated mosquito management programs.

Male Drosophila melanogaster, like males of many other animal species, maleage and temperature affected the sperm number. Here we use Drosophilamelanogaster males of different ages and decreasing temperature on the spermnumber, to investigate the role of aging and temperature affected to sperm transferredto female during mating. The male ages were used to show that while maximizesperm number in young (2-3 days)and middle age (27-28 days) was contributed butmean value of sperm number between fifty replicate was different and also the resultsof one way ANOVA were significant between three age classes. Sperms after matingsoon counted from female reproductive system, the results are shown, mean value ofsperms when males exposed to cold temperature (15°c) in young and middle aged,sperm number was around 4000, and old male aged (952-53 days) around 2000, theseresults demonstrate that viability of sperm produce in males after 27- 28 days, will bereduced more than young to middle aged.

There are many factors that influence the success of silk production. Bacterialflacherrie considered the most important factor. Antibiotics showed promising resultsfor controlling of silkworm diseases and to improve the production of silk andharvesting superior crop. The effect of antibiotic (Gentamicin) upon the infection withbacterial flacherrie was discussed. Gentamicin as a cheap antibiotic in Egypt can beused easily by trainees and farmers. It was found that Gentamicin significantlyincreases the effective rate of rearing (ERR %) and larval weight (97.333% and2.631gm, respectively). Single female and male cocoon weights (1.400 gm and 1.068gm, respectively) and male cocoon shell ratio (22.708%) were significantly increasedunder the effect of antibiotic treatment comparing with control. Polymorphism amongthe tested haemolymphal samples were investigated using SDS-PAGEelectrophoresis. A variation was detected in the protein banding pattern withconsiderable polymorphism (88.2 %), with the appearance of 2 monomorphic bands,12 polymorphic and 3 unique bands.

An experiment was conducted under laboratory condition to evaluate theinsecticidal activity of three newly compounds extracted from wastes from naturalorigin, Cyano acetyl urea (CAU), Benzimidazolyl acetyl urea (BAU) from urea andCyano acetyl hydrolyzate (CAH) from rice straw, on cotton leaf worm (Spodopteralittoralis) through exposure of fourth instar larvae to castor bean leaves whichimmersed in different concentrations from tested compounds. In addition, themorphogenic abnormalities were recorded.The other objective of this study is to evaluate the potential of the randomamplified polymorphic DNA (RAPD) assay for the detection of geneticpolymorphism between control and treated S. littoralis larvae, which have beenexposed to the tested compounds at both LC25 and LC70. Five primers namely: OP-01,OP-02, OP-03, OP-04, and OP-05 were used in this study.The present findings clear that, LC25 estimates of fourth instar larvae rangedfrom 0.092 to 0.154 % of (CAU), 0.191 to 0.225 % of (BAU) and 0.009 to 0.021 %of (CAH) while, LC70 estimates of fourth instar larvae ranged from 1.289 to 2.009 %of (CAU), 1.445 to 2.159 % of (BAU) and 0.339 to 0.627 % of (CAH).In addition, five primers OP-01, OP-02, OP-03, OP-04, and OP-05 generated amaximum of 26, 24, 20, 13 and 23 bands, respectively. RAPD profiles generated bythese primers revealed differences between control and treated samples with visiblechanges in number and size of amplified DNA fragments. Polymorphism ranged from44.4 to 100% as screened by the five primers among all samples. Taking all datatogether, higher polymorphism was recorded at LC70 (77.8, 84.4, and 86.4%)comparing corresponding values at LC25 (69.6, 80.3, and 79.4%) for larvae treatedwith CAU, BAU and CAH, respectively. Based on LC70, the highest polymorphism(86.4%) was observed in those treated with CAH comparing those either treated withCAU (77.8%) or with BAU (84.4%). Definitely, RAPD data confirmed thesusceptibility test as well as the morphological study, and suggest that DNA damageand the possible occurred mutations may appear to be the main factor influencing theevident polymorphism between control and treated larvae.

Within the region of East and Central Africa, the aposematic butterfly D.chrysippus is characterized by unusual ecology, due to the co-occurrence ofpolymorphism, mimicry and sex ratio distortion. In this paper, we describe a surveyconducted for D. chrysippus at Khartoum, based upon morphological and molecularinvestigations. The goal of the study was to determine whether Sudan is a part of thepresumed hybrid zone of D. chrysippus in Africa, where the butterfly shows theunusual ecology. D. chrysippus was found to display considerable colour patternpolymorphism. Only one mimetic form, the batesian mimic, female Hypolimnasmisippus was recorded. The population sex ratio of D. chrysippus did not showsignificant deviation from the 1:1 ratio. Molecular tests for the male-killing bacteriaSpiroplasma yielded negative results. The study concluded that central Sudan belongsto the hybrid zone but lacks its characteristic ecology.

Protein, isozymes and RAPD-PCR were conducted to assess the biochemicaland molecular characterization for three subspecies of honey bee worker, Apismellifera L. Low polymorphism percentages were recorded in different proteinpatterns ranging from 18 to 42%. Eighteen, five and four unique bands distinguishedthe Egyptian, the Italian and the Carniolan subspecies, respectively. The isozymesystems recorded low polymorphism percentages, except peroxidase (67%). Highlevels of polymorphism were observed in RAPD-PCR profiles. 28 unique bands wereidentified out of 39 polymorphic ones; fourteen in the Egyptian subspecies, six in theItalian subspecies and eight in the Carniolan subspecies. These unique bands wereconsidered as molecular markers for these subspecies. The dendrogram separated theEgyptian subspecies from the other two subspecies with a highly genetic distance of0.25. The Italian and Carniolan subspecies were grouped into one main cluster with agenetic distance of 0.01 between them.

Microwave radiation in conjecture with two types of cold storage were used tocontrol adults of red flour beetle, Tribolium castaneum (Herbst) (Coleoptera:Tenebrionidae) and lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera:Bostrichidae). The mortality rate of the insects at 200 W microwave power level,different exposure times (0, 2, 4, 6 and 8 min), for 48 h pre and post cold storageperiod was determined. A direct relationship between mortality rates and exposuretimes was detected. Susceptibility of the insects in implementation radiation priori orpost cold storage execution was significantly different. Apparently, when the insectswere exposed to microwave radiation prior to cold storage, the mortality rates wereincreased. In comparison, the adults of wheat flour beetle were more tolerant than thecorresponding adults of the lesser grain borer. Wheat germination rate was diminishedby post cold storage microwave radiation procedure. The plumule length did notreduce after exposure to microwave energy and cold storage. Together, data suggestconcurrent application of microwave radiation followed by cold storage could be apotential measure for control wheat stored-product beetles.

The biological and biochemical effects chloropyrifos, camphor extract andtheir combination were studied against the 4th instars of Spodoptera littoralis undersemi-field conditions. The results indicated that the LC50 for chloropyrifos was 0.08ppm and 13.3 x 103 ppm for the camphor extract. The estimated Co-toxicity factorwas 13.2 So, there is an additive effect between camphor oil and chloropyrifos againstS. littoralis.Oil extract of camphor prolonged larval and pupal duration also the same effecthappened when using mixture of camphor extract and chloropyrifos. Thisprolongation was accompanied with a reduction in pupal weight of the treated larvae.While when using chloropyrifos only the larval and pupal duration were shortenedAlso % of pupation and % of adult emergence were more decrease in plant extractand insecticide mixture than each compound alone.Biochemical studies showed that, total protein content of larval instarsdecreased by 31, 26 and 13.5 % for camphor extract, chloropyrifos and itscombination, respectively. Also, the activity of acid phosphatase, α-esterase wassignificantly decreased. Where the alkaline phosphatase, activity increased Whencompared with control.

The present experiments were carried out at the plant protection researchstation, Kaha, Qalubia Governorate, Egypt to study the efficiency of the bioagentBacillus thuringensis var. Kurstaki against the 2nd instar larvae of the lesser cottonleafworm, Spodoptera exigua (Hb). Results revealed that the 2nd instar larvae weremore susceptible to B. thuringiensis towards 4th instar larvae. Accumulative mortalitypercentage of the 2nd instar larvae of S. exigua treated with the differentconcentrations of B. thuringeinsis kurstaki, increased gradually with increasing thetime elapsed after treatment. There was a stronger larvicidal effect on the 2nd instarlarvae giving 2.889x106 and 6.267x1013spore/ml for LC50 and LC90 respectively. Themean larval duration for both LC50 and LC90 of B. thuringeinsis var. kurstaki waselongated compared to the control treatment. Pupal duration was insignificantlyaffected when 2nd instar larvae of S. exigua were pretreated with LC50 and LC90 of B.thuringeinsis kurstaki. The percentage of pupation was significantly decreased than incase of the control for both treatments, respectively. On the other hand, thepercentage of pupae that succeeded in surviving and reaching the adult stagedecreased in case of treated larvae than in case of the control for both treatments.

The present study was recorded the penetration rate, the migration% and thedistance covered by the species [(Steinernema riobrave, Steinernema sp. (S3),Steinernema rarum, Heterorhabditids sp. (Hp2), Heterorhabditids sp. (Hp4) andHeterorhabditids indica)]. In addition, the relation between these activities and thelipid contents of each species were revealed. The authors found that, there areconsiderable variations in migration rate between entomopathogenic nematodesspecies and the migration is not affected by the original amount of lipid content in thespecies. Species that have high lipid contents don’t show high migration rate but theinfectivity was affected by the amount of lipid contents where the species contain highlipid contents recorded high penetration rate of Galleria mellonella.

The field experiment was conducted during summer and winter seasons toevaluate seven varieties of beans (Phaseolus vulgaris L.) for their relativesusceptibility against some sap sucking pests Tetranychus urticae Koch, Bemisiatabaci (Gennadieu), Aphis craccivora Koch, Thrips tabaci Lindquist and leaf miner,Liriomyza trifolii (Burgess). The tested bean varieties were: Medina (V1), R9251 (V2),Teresa (V3), Luvalde (V4), Al-Hanna (V5), Alexandria (V6) and Excalibur (V7). Noneof the varieties escaped the infestation of all these pests. Generally the population ofT. urticae and T. tabaci were higher in summer than in winter, while population of B.tabaci and L. trifolii were higher in winter. Relative susceptibility of bean plantschanged according to plantation season as, V6, V6, V5, V6 and V3 hosted the lessnumber of T. urticae, B. tabaci, A. craccivora, T. tabaci and L. trifolii in winterseason, respectively. While in summer plantation, V5, V1, V4, V1 and V7 hosted theless number of the same pests, respectively.

In this study, the activity of invertase, glucose oxidase and diastase enzymes inhypopharengeal gland were determined for Egyptian and Carniolan honeybees. Threecolonies were chosen randomly from the population of each race for assaying theenzymes activity on three ages of worker bees: Newly emerged, 10-15 day old andforagers. The results show that the hypopharengeal gland expressed the three enzymesin different quantities in the three ages except invertase which could not be detected innewly emereged bees of Carniolan race. Generally, diastase is significantly moresecreted than invertase and glucose oxidase, and the secretion of newly emerged beesis significantly less pronounced than in nurse and foraging age. The significantdifferences between the two races were obviously expressed in foragers for invertaseand diastase enzyme, and in nurse bees for glucose oxidase in favor of Carniolan race,whereas the difference was significantly higher in newly emerged bees for Diastaseand invertase in Egyptian bees. This result establishes different views of the secretiontrend of the three enzymes in the two honeybee races, which may considered as racespecificcharacteristic.

The present work was conducted to evaluate controlling the subterranean sandtermite, Psammotermes hybostoma using some unordinary natural oils and others inthe laboratory and field as indoor and outdoor investigations, respectively. The resultswere analyzed statistically by T-test.Ten kinds of oils [Caraway, Onions, Garlic, Clove, Peppermint, Basil,Eucalyptus (Camphor), Sesame, Tar and Fenugreek] and three other substances[Neem seeds extraction, gum bees powder (Propolis) and aluminum sulphate powder(Alum)] were used. These materials have been observed under laboratory conditions,and field conditions at two regions namely; El-Konooz region and the farm land ofSouth Valley University during the period from January to December 2011, and inthree infected buildings at El-Konooz region during the period from February till June2012 in Qena city.Laboratory results showed that, the highest mortality rate was recorded by usingcaraway oil (100 workers per hour). In contrast, the lowest mortality rate wasobserved when propolis and neem seeds extraction used (0.26 workers per hour)equally.On the other hand, the outdoor field results agreed with the laboratoryinvestigations. Thus, the highest ratio of sand termite individuals, caught incorrugated cardboard traps allover one complete year, was in the traps treated withpropolis (95.6 %). In contrast, the lowest was (0.24 %) with clove oil. The ratio was(0.0 %) in the presence of the following oils (caraway, basil, camphor, garlic,peppermint and tar) at El-Konooz region.Moreover, field results of the farm land of South Valley University showed thatthe highest ratio of sand termites individuals was in the traps treated with propolis(92.7 %). Inversely, the ratio was (0.0 %) in the cases of the following oils (caraway,basil and garlic).On the other hand, statistical analysis on the feild results showed highlysignificant differences between the mean numbers of the individuals caught in trapstreated with all oils and their control. Whereas, no significant differences wererecorded in the case of propolis and neem seeds extraction and their control.In relation to the results on infected buildings, the total numbers of individualsobtained from corrugated cardboard pieces were zero in the doors and windowsframes that treated with the following oils (caraway, basil and camphor), despitecontinuing injury in the control case (2070 and 1424 individuals from doors andwindows frames, respectively).Thus, it is recommended using the most effective repellent oils (caraway, basil,camphor, garlic, peppermint, tar and clove) in subterranean termite control insidebuildings by spraying infected timber or injection in the ground or by traps in the soilinstead of chemical pesticides with harmful impact on the environment and health.

The female age including, 2-3 days aged old (young aged), 17-18 days agedold (middle aged) and 31-32 days aged (old aged) mated with virgin male (5-6 daysaged old). The results by SPSS software analayzed that in almost all of experimentalyoung aged old had significantly level than middle and old age. Fecundity elements,in young age was greater than middle and old age, also the female ovariole elementswhen mated with male young age was more than middle and old age. This variabilitysuggests that female age effected on the male reproductive performance and femalefitness traits. Therefore, the female age specific possibility occurrence on reproductiveaccess as follows by: young > middle >old aged.

Predaceous mites play an important role in the biological control ofphytophagous mites and insect pests such as thrips and whitefly. Biologicalparameters of Amblyseius fallacies Garman were tested under two degree oftemperature 20 and 30°C and R.H.70±5% feeding on Thrips tabaci at Fac. Agric.,Fayoum Univ., Egypt from March till June. The results indicated that the mean ofimmature periods at 20°C for eggs, larvae, protonymphs and deutonymphs, reached(2.64, 1.14, 1.86 and 2.79 days) and (2.46, 1.07, 1.93 and 3.21 days) for females andmales, respectively. At 30°C the mean of these periods for female reached (2.64,1.00, 1.64 and 3.21 days), while for males reached (2.50, 1.07, 1.29 and 3.43 days),respectively. The adult longevity period averaged at 20°C were 10.29 & 9.29 days,while at 30°C averaged were 8.14 & 6.86 days for female and males, respectively.Through the oviposition period which averaged between 6.43 and 4.71 days the meanof eggs deposited per female reached to 8.86 and 9.29 eggs at 20°C and 30°C,respectively. The total mean of food consumption for immature stages ( protonymphsand deutonymphs) reached to 3.00 and 2.43 preys at 20°C, while reached to 3.43 and2.71 preys at 30°C for females and males, respectively. The adult stage consumedfrom 19.89 to 9.14 preys at 20°C and 23.58 to 10.57 preys at 30°C for females andmales, respectively.

In a field survey, 16 eriophyoid mite species were collected from eight speciesof fruit trees, among which two species were found to be new record to Egypt. Theywere Tegolophus guavae (Boczek, 1960) on Psidium guajava L. (Myrtaceae) whichcauses rust on leaves, and Aceria ziziphi Mohanasundaram, 1990, vagrant withoutdamage on Ziziphus spina-christi Willd (Rhamnaceae). These species wereredescribed and illustrated from local material. A total of 65 eriophyoid mite speciesin superfamily Eriophyoidea has been recorded in Egypt due to literature. Thesespecies belong to three families, seven sub families, seven tribes and 27 genera. A listof these species has been constructed and presented herein.
