This study investigated the efficiency of intrahaemocoelic injection of sublethal concentration (LC20 = 5.7×103 cells/ml) of Salmonella typhimurium in the induction of immune response in 5th larval instar of Spodoptera littoralis. The role of antimicrobial peptides (AMPs) induced in the larval hemolymph was examined as natural antibiotics against different Gram-negative (G-ve) or Gram-positive (G+ve) bacteria. Where the larval plasma injected with Salmonella showed a significant antimicrobial activity against different strains of pathogenic bacteria (Staphylococcus aureus, Salmonella typhimurium, Escherichia coli and Enterococcus faecalis). The biochemical characterization of the immune hemolymph indicated drastic changes in both the total protein content and the protein banding patterns following bacterial injection. The total hemolymph proteins (THPs)decreased significantly 48 h post-Salmonella-injection. The hemolymph proteins profile was also qualitatively changed through the induction of new proteins and the disappearance of others simultaneously, which may be attributed to their participation in the immune reactions. The appearance of six new synthesized protein bands that were found to be specific for Salmonella injection, with a characteristic band of MW ~22 KDa predicting that this protein band may be Attacin-like AMP.

Seasonal abundance of thrips Frankliniella occidentalis (pergaade) and the relation between its population activity and weather factors were studied during 2017 and 2018 seasons on the Rose plants at. At El-Orman Garden, Giza Governorates Data of 2017 season indicated that the thrips population have two activity periods; the first which has the highest number occurred in mid-April while the 2nd one occurred in half of December. On the other hand, 2018 season data indicated that F. occidentalis population also have two activity periods; the first one with the highest number occurred in the first of May while the other occurred in half of December too. Statistical analysis shows that the simple correlation and simple regression between thrips population and each of the maximum, minimum temperature and relative humidity with were insignificant at El-Orman Garden, Giza Governorate. In 2017 season, generally the infestation whis Thrips, F. occidentalis was relatively higher than 2018 season. Infestation with thrips reduced chemical components; oil, protein and vitamins in flowers of rose plants.

This study was carried out to study the effect of treated Duranta seedlings Duranta sp. fam: Araliaceae by different concentrations of Triacontanol hormone (TRIA) on the infestation by Duranta aphid, Aphis durantae Theobald (Homoptera: Aphididae) and Tetranychus urticae Koch (Fam: Tetranychidae) under glasshouses conditions. This study was carried out at two locations (Governorates), El-Orman Garden (Giza Governorate) and International Garden (Alexandria Governorate) throughout 2018 season. Three treatments (concentrations) of Triacontanol hormone were done in both the two locations, small concentration (25ppm), medium concentration (45ppm) and high concentration (65ppm), beside fourth treatment which did not treat with any hormone (control). Duranta plants which treated with a small concentration of (TRIA) (25ppm) were lower infestation by both A. durantae and T. urticae comparing to control. Duranta plants which treated with a medium concentration of (TRIA) (45ppm) were had no significant effect on the infestation by the two pests compared to control. On the other hand, duranta plants which treated with a high concentration of (TRIA) (65ppm) were higher infestation by both the two pests comparing to control. From obtained results we can recommend using Triacontanol hormone (TRIA) on the Integrated Pest Management (I.P.M) programs by doses showed at this study.

The present study designed to investigate the effect of three entomopathogenic fungi (EPF), Beauveria bassiana (Biovar), Trichoderma album (Biozed) and Metarhizium anisopliae (Bioranza) on greater wax moth Galleria mellonella larvae. The results revealed that the LC25 values of T. album, M. anisopliae and B. bassiana against G. mellonella larvae were 14.08, 44.20 and 57.82 ppm, respectively. The LC50 were 104.03, 252.55 and 389.05 ppm, respectively for the same biocides. T. album was the most toxic biocide for controlling G. mellonella larvae, While B. bassiana was the least toxic one. The slope of the tested compounds was 0.78, 0.89 and 0.81 for T. album, M. anisopliae and B. bassiana, respectively. The toxicity index of the tested compounds was 24.35 & 26.74 & 31.85 and 41.18, respectively. On the other hand, the relative potency of the three tested compounds at LC25 and LC50 were 1.31 & 1.54 and 4.11 & 3.74 fold for both M. anisopliae and T. album compared to 1.00 fold in case of B. bassiana. The results showed that the cumulative mortality percentages of G. mellonella larvae treated with the three products can be arranged according to the most efficient compounds 47.61, 41.52 and 39.67%, respectively for T. album, M. anisopliae and B. bassiana compared to control. Also, the results indicated that three tested biocides have a significant effect on some biological aspects of G. mellonella larvae. B. bassiana was the most effective biocide on larval and pupal duration, pupal mortality, pupal weight and sex ratio percentages. While, treatment with M. anisopliae reduced male longevity, and the malformation percentages recorded as 27.35% compared to control. But, T. album had the most toxic effect on accumulative larval mortality, pupation percentages, pupal duration and significantly decreased the female sex ratio than control. The three tested biocides had an effect on some biochemical parameters of G. mellonella larvae. The activity of amylase enzyme had a significantly decreased effect after five periods of treatment compared to control. A significant increase in relative activity in protease enzyme was recorded after treatment with the three EPF. A fluctuation in the enzyme activity of transaminase enzymes, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) was estimated. There was also a significant reduction in total protein content. Results cleared that, significantly increased gradually in total lipid up to ten days after treatments. The results indicated that the tested bio-products can be used in honey bee colonies as a strategy to control G. mellonella larvae as one of the components of biological control programs.

The greater wax moth, Galleria mellonella is an important pest of wax combs of the honey bee in the world. The current investigation aimed to assess the effects of Apitoxin on the most important adult life parameters and reproduction of this pest. The freshly ecdysed 3rd instar larvae were treated with a series of Apitoxin concentrations (4000, 2000, 1000, 500, 250, 125 ppm) via the artificial diet. The present results can be summarized as follows. The adult emergence was slightly blocked only at the higher three concentration levels. Apitoxin failed to affect both adult survival and morphogenesis. The total longevity was significantly shortened, in a dose-dependent course. The ovarian maturation (pre-oviposition) period was prolonged, except the highest one at which this period was slightly shortened, as an odd datum. The reproductive life-time (oviposition period) was remarkably shortened, in no certain trend. Also, the post-oviposition period was considerably shortened. Apitoxin exerted a diverse action on the reproductive efficiency of adult females since the oviposition rate was enhanced or inhibited, depending on the concentration, but in no certain trend. Both fecundity and fertility had been significantly reduced, in a dose-dependent course. The incubation period was considerably prolonged in a dose-dependent manner.

Fig tree borer, Trichoferus griseus (Fabricius) (Coleoptera: Cerambycidae), is one of the very dangerous pests of fig trees at the Egyptian Northwestern coast. The prevailing environmental conditions at this coastal area (low precipitation, rainfed agriculture, soil salinity and hot summer season) support the population buildup of this pest to induce inestimable infestation. The current study aims to quantify the severity of the infestation of fig tree borer under the different soil moisture contents (moist and non-moist sites) and to estimate the influence of fig trees watering practice on the survival of Trichoferus larvae. Significant variation has been detected by comparing the mean infestation incidence between both sites on the monthly and annual levels. Under the annual watering practice, barely fluctuation in the counted numbers of exit holes was recorded through the study period, which, in turn, reflected on the corrected infestation percentages that recorded a noticeable reduction (2.04%) in 2018 year compared with the previous years. Rising moisture content in the internal fig tissues may hinder the colonization capability of Trichoferus larvae. The continuity of annual watering practice could affect Trichoferus infestation, especially when engaged in the integrated program dedicated to combating this pest..
