Gamma radiation and heat treatments are considered promising techniques for disinfestation treatments against stored product pests. This study aimed to evaluate the effects of thermal treatment with 40, 50, 70 and 90°C and different doses of gamma radiation from 40 to 350 Gy on Sitotroga cerealella stages. The result demonstrated that the LD50 of gamma-irradiation was 57.7, 61.9 and 74.0 Gy in irradiated eggs, pupae, and larvae, respectively. Concomitantly, the complete mortality (100 %) of heat treatment was recorded at 40°C, while the 90°C caused 100 % mortality to larva and egg stages. The results indicated that the egg stage is highly sensitive to irradiation doses than larvae and pupal stages, while the pupal stage is highly sensitive to the heat treatments than eggs and larval stages. Consequently, treatment with low doses 80 Gy and low heat condition 40°C was more effective than the other combination treatments. The results suggested that 80 Gy & 40°C was an effective treatment to prevent the reproduction of S. cerealella and could use for managing this pest with was the environment.

A total of 26 fungal strains were isolated from aphids and tomato leaf miner as indigenous species and from red palm weevil and peach fruit fly as an invasive insect. Fungal strains tested for their abilities to attack both bean and wheat aphids. The mortality of aphids due to thesefungi was estimated. Results showed that eight entomopathogenic fungi Scopulariopsis brevicaulis, Verticillium sp., Fusarium chlamydosporum, Fusarium proliferatum, Fusarium semitectum, Pochonia chlamydosporia var. catenulata, Fusarium solaniand Fusarium verticillioides exhibited high virulence 60-100%. However, Scopulariopsis brevicaulis, Verticillium sp., Fusarium chlamydosporum and Fusarium solani proved to be the most virulent species against the target aphids inducing 90%-100% mortality.

The present study was carried out to record the population density of two aphids' species (the cotton aphid Aphis gossypii on pear trees and the mealy plum aphid Hyalopterus pruni on plum ones) and the green lacewing predator Chrysoperla carnea, which occurred in a mixed orchard containing both trees, during season 2019, in Qalubia Governorate. The obtained data showed that the occurrence of aphids' species on pear and plum trees covered the whole four months of study (March-June, 2019). Aphids' populations were the highest in their numbers, during the two months April and May 2019, on both the two trees species. The results indicated also that, the existence periods of aphids' individuals on both pear and plum trees were the same as those recorded in case of the predator C. carnea. A field experiment was performed by putting pheromone traps on plum trees (during the fruiting season from the second half of May to the first half of July, 2019). Highest total number of the peach fruit fly Bactrocera zonata males was recorded in pheromone traps during the first half of June, 2019 (when using one or two pheromone capsules on the same glued sheets, on the same plum tree). Generally, the lacewing predator C. carnea can be massed reared in the laboratory and released for controlling aphids on pear and plum trees and/or other fruit trees that are subjected to attack by the two aphids' species. Besides, the pheromone traps can be used against the peach fruit fly B. zonata on plum trees and/or fruit trees that suffer from pest attack. The uses of either C. carnea and/or pheromone traps can be applied with other available safe control methods, in the frame of Integrated Pest Management (I.P.M.) programs, for protecting man heath and the surrounding environment from pollution.

This study was evaluated the toxicity of three insecticides contains two effective substances, chlorpyrifos & lufenuron (Tempo XL), lufenuron & emamectin benzoate (Heater) and thiamethoxam & chlorantraniliprole (Folliam Felixi) against the 2nd and 4th larval instars of S. littoralis under semi-field condition in tomato field Ismailia Governorate during 2018 & 2019 seasons and assessing their biochemical effect against treated larvae. In laboratory results indicated that Heater had the highest efficacy against 2nd and 4th larval instars, with LC50 of 0.041 and 0.135 ppm for 2nd and 4th larval instars, respectively, followed by Folliam Felixi with LC50 of 0.076 and 0.233 ppm and finally Tempo XL with LC50 of 0.097 and 0.411 ppm for 2nd and 4th larval instars, respectively. Under the semi-field condition observed that the initial effect during 2018 & 2019 seasons, Heater proved to be the most effective and had the highest corrected larval mortality, while the general mean of residual activity was more than 90% in all treatments. In biochemical studies, alpha and beta esterases were the highest activities in S. littoralis larvae treated with tested compounds compared to untreated. The highest enzyme activity of acetyl- cholinesterase, acid and alkaline phosphatase was observed in Tempo XL, while in the case of Heater and Folliam Felixi there was no significant difference between them. The results also showed that with all treatments there was a significant decrease in the total protein.

A Field experiment was done at Plant Protection Research Institute Experimental Station, Qaha district, Qalubeiah governorate during 2018 & 2019 two cotton seasons. Thirteen compounds related to different groups were used; three of them were exposed to gamma radiation doses of 400 & 700 Gy for potentiating purpose. The treatments were Bacillus thuringiensis (Kurstaki), Beauvaria bassiana (Balsamo), B. thuringiensis +B. bassiana, B. bassiana+400 Gy, B. bassiana+700 Gy, azadirachtin, azadirachtin+400 Gy, azadirachtin+700 Gy, fertacho, fertacho+400 Gy, fertacho+700 Gy, profenofos and profenofos+amadene. The treatments aforementioned were evaluated against three pests of cotton bolls that were pink bollworm, Pectinophora gossypiella (Saund); spiny bollworm, Earias insulana (Boisd.) and Cottonseed bug, Oxycarenus hyalinipennis (Costa) population and infestation reduction percentages. Profenofos+Amadene was considered the best treatments caused reduction percentages in population and infestations against three pests used, followed by profenofos as well as fertacho+ 700 Gy nearly, azadirachtin +700 Gy, fertacho + 400 Gy, azadirachtin + 400 Gy, fertacho, azadirachtin, B. bassiana+700 Gy, B. bassiana + 400 Gy, B. thuringiensis +B. bassiana, B. thuringiensis and B. bassiana. In addition, the compounds used enhance the most cotton crop parameters acts in seed numbers, lint and seed weights during the two cotton seasons 2018 & 2019. So, gamma radiation can potentiate the three compounds of B. bassiana, azadirachtin and fertacho to become the most effective compounds on aforementioned three pests and cotton crop parameters compared with the same compounds without exposing to gamma radiation.
