governorate. The selected area was split into 7 plots and the control plot. Two spraying machines were used Pneumatic motor sprayer (Cifarilli) (20 L./Fed.) and Hand-held Hydraulic sprayer (Matabi) (56 L./fed.) for application enhancement. Seven compounds related to different insecticide groups were used; one of them (B. thuringiensis) was exposed to gamma radiation doses of 160, 320 & 640 Gy (gray) =for potentiating purpose. The treatments were Bacillus thuringiensis (Kurstaki), B. thuringiensis +160 Gy, B. thuringiensis +320 Gy, B. thuringiensis +640 Gy, azadirachtin, B. thuringiensis +azadirachtin and diflubenzuron. The treatments mentioned 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. B. thuringiensis +640 Gy and diflubenzuron were considered the best treatments that caused reduction percentages in population and infestations against three pests used, followed by B. thuringiensis +320 Gy, B. thuringiensis +160 Gy and B. thuringiensis + azadirachtin, azadirachtin and then B. thuringiensis. In addition, the compounds used to enhance the most cotton crop parameters acts in seed numbers, lint and seed weights during the two cotton seasons 2018 & 2019. So, gamma radiation (160, 320 & 640 Gy) could potentiate B. thuringiensis to become the most effective compound on mentioned three pests and cotton crop parameters compared with the same compounds without exposing to gamma radiation; also, knapsack motor sprayer contribute to success the pest control comparing with Hand-held Hydraulic sprayer (Matabi) (56 L./fed.) that was the least efficient according to homogeneity of droplet spectrum. It could be recommended to use these Bio-Insecticides with Low Volume spraying equipment with not less than (20 L/Fed.). A satisfactory coverage was obtained on cotton plants. The spectrum of droplets ranging between 122-185 m (VMD). With a sufficient number ranging from 33-253 N/cm². The rate of performance of Pneumatic motor sprayer (Cifarilli) (20 L./Fed.) was 12 Fed./day. It was the best equipment, but the lowest rate of performance was Hand-held Hydraulic sprayer (Matabi) (56 L./fed.) since it could spray only 3.45 Fed./day. Data showed that bio-insecticides may be recommended in integrated pest management because of their safety on animals, man and environment. Also, Low Volume spraying reducing the time lost in the process filling the machines with the spray solution and saving the lost spray on the ground.

The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net Provided for non-commercial research and education use.Not for reproduction, distribution or commercial use. ABSTRACT Article HistoryField experiments were carried out of about 14 karats planted with (Giza 86) cotton variety during seasons 2018 and 2019 on 15 th July and 1 st , 15 th August in a field located at Qaha Research Station, Plant Protection Research Institute, Qalyoubia governorate. The selected area was split into 6 plots and the control plot. Two alternative products include Chlorpyriphos (OP's), and Chlorflurzoran (IGR's) were sprayed by using Rotary Matabi sprayer (18 L./fed.) on cotton field highly infested with cotton Spiny bollworm, Earias insulana larvae. All tested Insecticides revealed a significant negative influence on Earias insulana larvae. The most effective on reduction percentages of bolls infestation was Chlorpyriphos with NU-FILM -17 SPREADER ® 1% ,5% followed by Chlorflurzoran with NU-FILM -17 SPREADER ® 1% ,5% with Rotary Matabi sprayer (18 L./fed.). It could be recommended to use these Insecticides with Low Volume spraying equipment with not less than (18L/Fed.). A satisfactory coverage was obtained on cotton plants. The spectrum of droplets ranging between 120-170 m (VMD). With sufficient number ranging from 13-265 N/cm². The rate of performance of Rotary Matabi sprayer (18 L./fed.). was 2.4 Fed./day. The results indicated that there was no significant difference between using NU-FILM -17 SPREADER ® 1% or 5% in reduction percentages of bolls infestation. Using both Chlorpyriphos and Chlorflurzoran with NU-FILM -17 SPREADER ® 1% could be recommended in controlling Spiny bollworm, Earias insulana larvae because it increased droplets numbers 54%, decreased droplet sizes 17 % and minimized lost spray on ground 44% which made good spray quality, homogeneity and spray coverage. Also, Low Volume spraying reducing the time lost in the process filling the machines with the spray solution and saving the lost spray on the ground certainly in small plantation around villages.

Background The Earias spp. are devastating pests which reduce cotton yield up to 40% as seed cotton. Efficacy of Metarhizium anisopliae and Beauveria bassiana as bio-insecticides were investigated against the spiny bollworm, Earias insulana Boisduval (Lepidoptera: Noctuidae), under field conditions in Egypt throughout two successive seasons 2018 and 2019. Results Results showed E. insulana population reduction during both seasons after bio-insecticidal applications. M. anisopliae strains (S1, S2) treatments showed significant reductions in the mean numbers of infested bolls with E. insulana after 14 days from the 1st spray. Reduction percentages of E. insulana infestation reached to 77.74 and 76.51% respectively, after application of M. anisopliae strains (S1, S2) treatments; then, the infestation reduction percentages increased to 88.48 and 85.41% after the 2nd spray by the same fungal strains; then, the infestation reduction percentages increased to 90.16 and 90.84% after 3rd spray of the same fungal strains in season 2018. In 2019 season, the infestation reduction percentages of E. insulana was 85.48 and 80.75%, after the 1st spray of M. anisopliae strains (S1, S2), respectively, which increased to 92.40 and 89.87%, after 14 days from the 2nd spray by the two fungal strains respectively, and then increased to 94.12 and 93.73%, after 14 days from the 3rd spray of M. anisopliae (S1 and S2) respectively. In season 2018, the infestation reduction percentage of E. insulana by B. bassiana strains (S1, S2) recorded 73.09 and 71.89%, respectively and 81.04 and 82.89% respectively, in season 2019, after 14 days of the 1st spray. While after the 2nd spray of the two tested B. bassiana strains, the infestation reduction percentage of E. insulana was 85.41 and 85.41% respectively, in season 2018, whereas it was 89.16 and 89.16% respectively, in season 2019. Then after 14 days of the 3rd spray by the same fungus strains, the reduction percentage of E. insulana increased to 86.56 and 85.35%, respectively, in season 2018, and 90.83 and 90.83% in season 2019. Conclusions Tested strains of B. bassiana and M. anisopliae fungi proved their potential for decreasing E. insulana infestation percentages through 2–3 spray treatments under field conditions.
