The wild plant F. bruguieri extracts caused some alterations in the lactate dehydrogenase activity in haemolymph and fat body of the last instar nymphs and newly emerged adults of the desert locust S. gregaria. Each of two concentration levels of methanolic (7.5 and 3.7%), petroleum ether (30.0 and 15.0%) or n-butanolic extract (30.0 and 15.0%) was applied against the penultimate instar nymphs through the fresh clover leaves, Medicago sativa, as a food.
Unexceptionally, all F. bruguieri extracts induced the LDH activity in the haemolymph along the nymphal instar, irrespective of the solvent or concentration level. The strongest inducing effect was exhibited in the mid-aged nymphs (62601.3±467.4 U/L in comparison with 53696.8±467.4 U/L of control congeners) after treatment with the higher concentration level of methanolic extract. On the contrary, the LDH activity was significantly prohibited in the newly emerged adults. The most drastically inhibited enzyme activity was determined (57744.3±467.4 U/L, compared to 62871.2±934.7 U/L of control congeners) after nymphal treatment with higher concentration level of n-butanolic extract.
With regard to the fat body, all F. bruguieri extracts prohibited LDH activity along the nymphs instar, irrespective of the concentration level. The most dramatically reduced activity was expressed in (9166.4±119.0 U/L vs. 22839.5±289.1 U/L of control congeners) after treatment with the lower concentration level of n-butanolic extract. In contrast, the plant extracts pronouncedly enhanced the enzyme activity in the fat body of adults, regardless to the extract. The most stimulatory effect was exhibited after treatment of the nymphs with the lower concentration level of n-butanolic extract.

Four bioinsecticides and a carbamate insecticide were bioassayed against the cotton leaf worm, Spodoptera littoralis, larvae by separate and/or successive applications. The obtained results reveal that Protecto was the most potent bioinsecticide compared with Viruset, Profect, and Bioranza. The obtained data also prove that the chemical insecticide, Kuik, was very toxic to the tested larvae. Successive applications with the bioinsecticides at different concentrations (LC25, LC50, and LC90) then LC25 of Kuik showed very promising results manifested by an outstanding increase in second and fourth larval instar mortality. Treatment of 2nd and 4th instar larvae with Protecto, Viruset, and Profect prolonged larval duration while treatment with Bioranza reduced larval duration. It was also observed that egg number and hatchability were affected by bioinsecticidal treatment.

The adult female and male of the phytoesiid mite, Euseius plumerii Abo-Shanf & Romeih sp. n. were collected from leaves of both White Frangipani (Plumeria alba) and Rose (Rosa hybrida cv. Huddly) at Giza Governorate, Egypt, then identified and described. Furthermore, the description of immature stages was also presented. The life history of this new species were documented on the two spotted-spider mite, Tetranychus urticae Koch movable stages which infested leaves of rose at three temperature degrees (20, 25 and 30±2 ºC) and relative humidity of 70±5%. The results proved that, 30ºC was the most suitable temperature degree which accelerated the life cycle, gave highly egg production and greatly prey consumption.

The present study was undertaken to understand the protease mediated resistance mechanism of Cry1C and Vip3A in S. litura. Proteases play an important role for convertion of protoxins to active toxin. Hence laboratory selection of Spodoptera litura (Fab.) with Cry1C and Vip3A was done for eight generations to develop resistance, which developed 30.32 and 285.47 fold resistance respectively. Fourth instar larvae from nine generation of S. litura were dissected in an ice-cold 20 mM Tris-HCl buffer (pH7). Major midgut proteases viz, azocaseinolytic, tryptic and chymotryptic were quantified by using azocasein, trypsin and chymotrypsin as substrate. Results revealed that lowest azocaseinolytic activity 0.896 U/gut was observed in Cry1C resistant strain of S. litura which was 2.57 fold less than susceptible. Similarly, Vip3A resistant strain recorded 1.08 U/gut azocaseinolytic activities, which was 2.13 fold less than susceptible strain of S. litura. There was 2.26 and 3.35 fold decrease in activity respectively in Cry1C resistant and Vip3A resistant S. litura over susceptible strains. Chymotryptic activity in midgut of susceptible stain of S. litura was 1.13 U/gut, whereas in Cry1C resistant strain it was 0.512 U/gut which was 2.20 fold less over susceptible strain. Similarly, in Vip3A resistant strain, lower chymotryptic activity was recorded as compared to susceptible, which was 1.66 fold less than susceptible strain. Maximum five protease isoforms were identified in the electrophoretic profile of susceptible S. litura. Remarkable variation was observed between susceptible and resistant S. litura for protease isoform. The Cry1C resistant S. litura homogenate showed three bands viz., Pro3, Pro4 and Pro5 while only two bands viz., Pro3 and Pro5 in Vip3A resistant homogenate of S. litura whereas five bands were observed in susceptible strain of S. litura.

The family Tabanidae is one of the important families of superfamily Tabanoidea, having medical and veterinary importance. In Egypt, there is no strict cladistic approach on tabanid flies phylogeny yet. The 20 available Egyptian tabanids under 2 subfamilies are analyzed cladistically. Cladistic analysis is based on 91 morphological characters depending on Single linkage, UPGMA, Complete linkage clustering methods (Cophenetic correlation value). This produces a well-resolved and firmly supported phylogenetic hypothesis on the generic relationships. Based on our phylogenetic results, the revised classification of examined taxa is consistent with the conventional classification.

A survey for Dipterous flies was conducted in 3 private sheep's' farms and 3 governmental slaughter houses at Abu Arish, Alquayiyah, (Eastern Jazan); Duhaygah and Mihliyah (Northern Jazan); Mizhirah and Industrial City (Southern Jazan). Each locality was visited weekly to collect the flies using aerial sweeping net. A total of 5312 specimens consisting of 12 species, 1 subspecies within 8 genera, belonging to 7 families: Calliphoridae, Sarcophagidae, Muscidae, Ceratopogonidae, Utilidae, Sphaeroceridae, and Chloropidae were recorded. Among the total flies collected in all localities Coproica vegans (Haliday) was the most abundant species followed by Anatricus erianceus Loew and they represented 72.74% and 21.71% of the total collection, respectively. On the other hand, Culicoides imicola Kieffer, Sarcophaga ruficornis (Fabricius) and Musca lucidula (Loew) were recorded in few numbers and they represented 0.09%- 0.1% of the total collection. Physiphora alceae (Preyssler) and Musca sorbens Wiedemann were recorded only from slaughter houses. In addtion, Sarcophaga dux Thompson is recorded for the first time from Jazan during the present investigation. For accurate location of sampling sites, details of the selected area such as longitude, latitude and altitude were computed using the global positioning system (GPS).

In this study, a mathematical model is made to estimate the median lethal concentration or dose (LC50 or LD50). The model is based on the data of different insecticide groups, where each one is represented by the effect of three insecticides over different orders of insects by using different application technique. The trend of change of the LC50 or LD50 is observed among the insect life cycle for each group of insecticides. It is shown that for an insecticide group, there is a clear trend for the change of the LC50 (or LD50) when going from an age stage to another. That trend is simulated for each group to predict the LC50 or LD50 at an age stage by knowing it at another stage and method of treatment used.

The present work is aimed to study diversity of odonatous adults and naiads species encountered in the River Nile current throughout Upper Egypt. This study has been curried out in five stations for two sequence years. The odonatous diversity was investigated by monitoring numerical, locality abundance, and periodical abundance diversity.
The numerical diversity showed eight odonatous species. Moreover, the adults (54.75% of the total catches) dominated the naiads (45.25%) as well as Lestidae and Lestes viridis on the levels of the families and species.
Regarding locality diversity, the highest abundance of adults and nymphs were recorded in two different sites (El-Mashtal and BananaIsland stations, respectively). Conversely, the lowest populations were recorded in Menshaa station.
On the other hand, the periodical abundance diversity indicated to importance of the two seasons, winter and summer during which the highest seasonal abundance for the naiads and the adults, respectively, in the most studied stations. In contrast, the minimum abundances of the naiads and adults were recorded during spring and winter, respectively. Thus, it could be seen seasonal abundant interference for both nymphs and adults, particularly, during spring. This result may be due to the long ages of the nymphs.
The variation of the seasonal abundance exceptive stations may not affect on the importance of winter and spring as the periods of the highest and lowest seasonal abundances because perhaps these stations, especially stations Ma, underwent some of the human activities of the commercial ports.

The current work was carried out to evaluate the biological effects of five insect growth regulators; applaud (buprofezin), consult (hexaflumuron) and match (lufenuron) as chitin synthesis inhibitors (CSIs), mimic (tebufenozide) as ecdysone agonist (EA) and admiral (pyriproxyfen) as juvenile hormone analogue (JHA) against the housefly M. domestica. The IGRs were applied by feeding the 1st instar larvae on diets mixed with the selected IGRs at different concentrations (10, 100, 1000 and 2000 ppm).
The results demonstrated that mimic and admiral were the most effective compounds and induced 100 % larval mortalities at 2000 ppm. Mimic was the most toxic compound and its toxicity index was 100.The tested IGRs induced a significant prolongation in the larval and pupal duration.The percent pupation was highly decreased compared to the control. All the tested IGRs induced a reduction in the pupal weight as well as a reduction in the adult emergence, which was completely inhibited at 1000, and 2000 ppm. All the tested IGRs caused a significant decrease on the longevity of both sexes as compared to the control. The fecundity and fertility greatly decreased and the sterility increased with the all tested IGRs. Admiral was more effective than the others.

Ceroplastes cirripediformis Comstock is collected for the first time from Egypt; it is a serious soft scale pest on guava trees, with a high occurrence reached to 371 individuals/ leaf in the highest generation at mid November 2006 at Qaliobiya governorate. A key with figures and illustrations was constructed to differentiate Ceroplastes Egyptian species. Moreover the seasonal fluctuation of different stages of this newly recorded species is included, where the pest total population and nymphal stage had two annual peaks per year. Also the pest had two annual generations per year on mid February and November. The associated parasite, Tetrastichus ceroplastae (Girault) is collected and identified. The relationship between this pest and its parasitic & climatic factors is studied to help in the integrated pest control management.

The treatment of penultimate and last nymphal instar of Schistocerca gregaria with Fagonia bruguieri resulted in a partial blocking of the adult emergence in proportion to the concentration level, irrespective of the type of the extract. A dose-dependent suppression of adult survival potential was determined after treatment of penultimate instar nymphs. Similar dose-dependent mortality of the emerged adults was recorded after treatment of last nymphal instar with the methanolic and n-butanolic extracts.
With regard to the adult morphogenesis after treatment of penultimate instar nymphs with different F. bruguieri extracts, the most deranging effect was exhibited by methanolic extract. After treatment of last nymphal instar, the adult morphogenesis was considerably affected by both the methanolic extract and n-butanolic extract, parallel to the concentration.
Irrespective of the time of nymphal treatment, sexual maturity of S. gregaria adults was hastened by both the methanolic extract and petroleum ether extract of F. bruguieri, especially at the higher two concentration levels. In contrast, n-butanolic extract exhibited a delaying effect on sexual maturity, especially at the higher two concentration levels.
Significantly shortened longevity was recorded after treatment of penultimate instar nymphs with methanolic and petroleum ether extracts but prolonged longevity was observed after treatment with n-butanolic extract. Treatment of the last nymphal instar with n-butanolic extract, especially at the higher two concentration levels resulted in accelerated adult aging (as indicated by remarkably shortened longevity).
A solitarization tendency of the gregarious adults was activated after nymphal treatment with the n-butanolic extract because some adults appeared with greenish color of both the external morphology and haemolymph.

All numbers of eggs produced by individual Yemeni females of Callosobruchus maculates (F) on various numbers of cowpeas were calculated. Yemeni females laid around 29, 62 or 29, 66 when supplied with one cowpea, but when provided with more than one and the egg production increased 31,7. Very rare two adults emerged from a single cowpea regardless the number of eggs laid on the cowpea. The daily quantity of eggs produced declined when females provided daily with new cowpeas and removed the old ones, which had access to the females. Developmental durations varied between individuals and the lowest and highest in developmental duration were observed.
