The comparison of attractiveness was done between materials in the same group and between the most attractive materials of each group. Results showed that fresh coriander leaves, dill leaves, and zucchini fruit were the most attractive materials of the green vegetables group to both sexes and a combination of coriander leaves and zucchini fruit increased the number of attracted male and female cockroaches. In case of plant seeds, roasted peanut was the most attractive to males and females, whereas peanut butter was the most attractive from oily materials. A mixture composed of equal amounts of roasted peanut, coriander oil, fresh coriander leaves, and zucchini fruit attracted more cockroaches than peanut butter. Addition of cockroach’s feces to the mixture increased its attractiveness against cockroaches.https://eajbsa.journals.ekb.eg/article_12150_2b10fe37e78bea4e1f06f539d852de99.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

IGRs and compounds from natural origin considered environmentally safe and less hazardous to non-target biota. So, the current study aimed to evaluate the insecticidal activity of the match (lufenuron) and rice bran (<em>Oriza sative</em>) extract and their effect on fraction protein and acid phosphatase (ACP) pattern of haemolymph of treated <em>Schistocerca gregaria</em>. The present findings cleared that, LC<sub>50</sub>s estimate for one-day old of 5<sup>th</sup> nymphs of <em>S. gregaria</em> were 35.66 and 541.71 ppm for lufenuron and<em> O. sativa</em> bran extract, respectively. As to fraction protein pattern, a maximum number of 65 bands were detected, at molecular weight ranged from 6.73 to158.31and 18 unique bands were scored. The epigenetic distance accounted for 1 for lufenuron and 0.76 for <em>Oriza sativa</em> bran extract, 20 days post-treatment. In addition, seven acid phosphatase bands were recognized in treated and untreated 12 samples, with Rf values ranged between 0.02 and 0.86. Three unique bands were scored. In conclusion, the treated nymph with the lethal concentration LC<sub>50 </sub>of the tested compounds (lufenuron and<em> O. sativa</em> bran extract) showed a significant change in protein fraction and acid phosphatase patterns of haemolymph, which was clearly reflected in high epigenetic differences between control and treated <em>S. gregaria</em> samples.https://eajbsa.journals.ekb.eg/article_12167_b5d94d3c2ac254385b901d8cbd0364d2.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

Results revealed significant<br />reduction in the total proteins of the treated larvae compared to the control<br />larvae. The<br />biochemical studies using (SDS-PAGE) revealed that there was a reduction in the<br />number of protein bands due to the treatment with either of the two fungi. The obtained results indicated that the application<br />of entomofungi as larvicidal agents against mosquito larvae caused significant<br />changes in the total protein profile of <em>Cx. </em><em>pipiens </em>larvae suggesting that<br />toxins secreted by these pathogens caused damage to the larval proteins which<br />finally leads to larval death. The<br />conclusion is that the fungal pathogens are important as natural biological<br />control agents of many<br />insect and other arthropods and frequently cause epizootics that significantly<br />reduce host population. This study recommends the use of <em>B</em>.<em>bassiana<br /></em>and <em>M</em>.<em>anisopliae</em> as biological control agents to the control of <em>Cx.<br />pipiens </em>larvae in order tosuppress this medical vector for public<br />health.https://eajbsa.journals.ekb.eg/article_12169_ba8402a82b77a09edbe16e9febcc7256.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

Results indicated that<br />the percent of infestation<br />with <em>B. zonata</em> in early mango varieties “Hendy & Founs” and moderate mango varieties “Zebdia & Awyesy” was high, while it was low in late mango varieties “Fagrklan & Kent” during the two successive seasons. Total numbers of natural fallen fruits in early<br />mango varieties “Hendy & Founs” were more than the other varieties (moderate and late mature varieties) during the two<br />successive seasons (2014 & 2015). Also, the average numbers of infested fallen fruits in early<br />mango varieties “Hendy & Founs” were more than that of the other varieties (moderate and late mature varieties) during the two<br />successive seasons (2014 & 2015). The percentage of infestation descendingly<br />arranged according to<br />different reasons such as susceptibility of variety to infestation as follows: early mature, moderate mature and late mature varieties during the two successive<br />seasons, respectively. The percentages of infestation with <em>B. zonata</em> were (95.8 & 93.0), (90.3<br />& 88.1) and (85.6 &76%).While, thatrecorded<br />by<em>C. capitata</em> were (4.2 & 7.0), (9.7 & 11.9) and (14.4<br />& 23.2%) for the<br />three tested varieties (early, moderate<br />and late varieties) during the two successive seasons, respectively. Statistical analysis showed significant and high significant differences between the percentages of infestation by <em>B. zonata</em> and <em>C. capitata</em> of the three tested varieties (early, moderate and late varieties) during the two successive<br />seasons. The weather factors (max. and min. temperatures as well as relative<br />humidity) affected % infestation of fallen fruits of mango trees<br />with <em>B. zonata</em> and <em>C.<br />capitata </em>during the two successive seasons (2014 & 2015). During first season,<br />fruit infestation was positively significant with min. temp. and relative humidity for early and moderate varieties. While, during the second season, infestation<br />of early varieties was positively significant for max. temp. But, it was significantly<br />negative for relative humidity.

Two applications were implemented at interval of 15-days between each. The potency of the tested control methods was recorded at 3, 5, 10 and 15-days from each application as reduction percentages in the larval infestation caused by tomato leaf miner, <em>Tuta absoluta</em> larvae on tomato vegetable plants. Nowadays, finding a safe control program is the objective of all researchers. The goal of this work is to investigate the effect of gamma radiation on the entomopathogenic nematodes,<em> Steinernema carpocapsae</em> BA2, the egg parasitoid, <em>Trichogramma evanescens</em> in comparable with the insecticidal applications for controlling the pest infesting tomato fruits under field conditions. Results showed that 2 Gy irradiated <em>S. carpocapsae </em>BA2 was substantially more effective in controlling the insect larvae compared with normal nematodes. Based on the general mean reduction in infestation rates caused by the larvae of the pest as mean average of two successive applications, the efficiency of these agents could be decendingly arranged in order as follows: irradiated nematode at rate of 80IJ's+2Gy /ml, irradiated nematode at rate of 40 IJ's+2Gy/ml, normal nematode at rate of 80 IJ's /ml, , The insecticide proclaim, irradiated nematode at rate of 20 IJ's+2Gy/ml, normal nematode at rate of 40IJ's/ml,the insecticide, match, irradiated nematode at rate of 10IJ's+2Gy/ml, the egg parasitoid, <em>T. evanescens</em>, normal nematodes at rates of 20 IJ's/ml, 10IJ's/ml and the insecticide, chlorfan.
