A. MAbdallahDepartment of Pesticide chemistry and Technology, Faculty of Agriculture, Alexandria UniversityJournal Article20200229The entomopathogenic fungi (EPF) have received considerable attention for their potential use in biological control of insect pests. In this study, twenty four native strains were isolated from Alexandria governorate. This isolates were identified as 21 <em>Beauveria bassiana</em> (Ascomycota: Hypocreales) isolates and three isolates of <em>Metarhizium anisopliae</em> (Ascomycota: Hypocreales). Isolates were preliminary evaluated at 1x108 conidia ml-1 under laboratory conditions against 3<sup>rd</sup> instar larvae of <em>Spodoptera littoralis</em> and 4<sup>th</sup> instar of G. mellonella larvae. In addition, concentration-mortality relationship was conducted for selected three native <em>B. bassiana</em> isolates compared with two exotic isolates <em>B. bassiana</em> (Bio-power) and <em>M. anisopliae</em> (Bio-magic). The result revealed that the larvae of <em>G. mellonella</em> were more sensitive than <em>Spodoptera littoralis</em> to all EPF isolates with LT<sub>50</sub> range (6.28– 11.21days) and (7.81–13.28 days) respectively. The results indicated a significance difference (α = 0.05) for 13 native EPF isolates in their speed of kill (LT50) toward G. mellonella than S. littoralis. In addition, the concentration–mortality relationship assay showed that larvae mortality increase in a linear relationship with conidia concentration and the Bb-Mo12 a native isolate causing higher mortality percentage in both tested larvae, while Bio-power caused the lower mortality percentage in both larvae at higher tested concentration. The result show that Bb-Mo12 isolate have a lower LC<sub>50</sub> 1.3X10<sup>6</sup> and 1.1X10<sup>7</sup> conidia ml-1 toward G. mellonella and S. littoralis larvae respectively. from these results, we could conclude that there are a variation between native EPF isolates in their virulence toward insect pest and some isolates have a promising potential for use as biocontrol agents in the field of insect control.

A.El SharkawyPlant Protection Research Institute, ARC, Dokki EgyptJournal Article20200229 Studies on the toxicity of some new insecticides against <em>Pectinophora gossypiella</em> (Saunders) and <em>Earias insulana</em> (Boisd.) eggs were carried out under laboratory conditions. Field Recommended concentrations (FRCs) of three insecticides <em>viz., </em>Trebon (Etofenprox 30% EC), Cygron (Alpha-Cypermethrin 7% + Flufenoxuron 3% EC), and Raner (Methoxyfenozide 24 SC %) were tested against both eggs of PBW & SBW. Also, persistent toxicity of the tested insecticides was determined against the most susceptible life stage (adult) of three wasps of egg Parasitoid <em>Trichogramma </em>spp., <em>Trichogramma evanescens</em>, <em>Trichogrammatoidea bactrae </em>and <em>Trichogramma brassicae</em>. Results regarding the harmful effects of the insecticides on eggs hatchability of PBW revealed that Trebon caused the highest percentage of mortality (95.52%) followed by Cygron treatment (93.39%), while Raner caused the less percentage of egg mortality (22.35%). There were insignificant differences between mortality percentages caused by insecticides (Trebon& Cygron) and which obtained by <em>Trichogramma evanescens</em> (90.61%). In case of SBW, Trebon caused the highest percentage of mortality (78.7%) followed by Cygron (67.5%) and Raner was the least effective (32.82%) whereas , eggs mortality caused by <em>Trichogramma spp. </em>ranged between(65.72 - 75.1%) with no differences than those caused by Trebon& Cygron as in case of PBW. On the other hand, Trebon and Cygron showed a strong impact on the tested parasitoids, in contrast Raner was the least one on the tested parasitoids.Regardless of used insecticides, <em>T. evanescens</em> achieved the highest percentage of parasitism (46.53%) compared to 28.82& 20.3l% for <em>T. bactrae</em> and <em>T. brassicae</em>, respectively, whereas, percentage of adult emergence did not differ significantly between the three species of <em>Trichogramma</em>.
On the basis of this study, it could be concluded that Trebon and Cygron proved highly toxic to the tested pests and showed a strong impact on the tested parasitoids and could not therefore be used in combination with<em> Trichogramma </em>releases, whereas, Raner, is considerably mildly toxic for the pests and less harm for the bio-control agents.

Results showed significant differences between different plant species/cultivars and population density of these insects and also with their associated predators. Photosynthetic pigments (Chlorophyll a, Chlorophyll b and Carotenoids) analysis showed negative relationship with sap sucking insects infestation. Also different leaf biochemical components such as total phenol, total soluble sugars and total free amino acids revealed negative relationship with sap sucking insects infestation, while total flavonoids analysis showed insignificant differences. These results could be concluded the importance of cultivar selection in any integrated pest management program as well as the effective role of different plant biochemical components on plant resistance against insect pests

Field Recommended concentrations (FRCs) of three insecticides <em>viz.,</em> trebon 30% EC (Etofenprox), cygron 10% EC (Alpha-Cypermethrin- Flufenoxuron), and raner 24 SC % (Methoxyfenozide). The treated trichogrammatids were<em>, Trichogramma evanescens, Trichogramma bactrae </em> and <em>Trichogramma brassicae, </em>and the concerned immature stages at the time of treatment were prepupae, freshly formed pupae and mature pupae (3, 5 and 7-days after parasitism).

Regardless of the parasitoid species and the treated ages trebon had a severely impact on <em>Trichogramma</em> emergence (48.02%), raner was the least harmful (58.56%) whereas; cygron caused a moderate effect (54.58%). The 3 days age was the less influenced age, as it gave the highest percentage of emergence where, total average was 60.31%) after exposing to insecticides. Regardless the insecticide used, the percentage of adults' emergence was significantly differed by the age of immature stages for each <em>Trichogramma</em> specie, for example, In case of <em>T. bactrae</em> and <em>T. brassicae</em>, the 3 days age gave the higher percentage of emergence which being 56.8& 63.97%, respectively, whereas, 7 days age gave the less percentage of emergence which retched 49.2& 45.03%, respectively, and 5 days age gave the midst percentage which being 51.17& 53.13%.
In contrast of the percentage of emergence, exposing any <em>Trichogramma</em> species at 7 days age (mature pupae) to insecticides had the harmless effect on the percentage of females compared to the other two ages.
