Meanwhile, B. bassiana is highly susceptible to the damaging effects of solar radiation (specially UV) which in turn reducing its insecticidal efficacy. This report presents initial results from laboratory studies aimed at assessing the potential of oil formulations to enhance efficacy of B. bassiana against aphid pests. Four oil formulations are used under investigation in this study; orange, star, sunflower, and soybean oil. Aphid population reduction % were determined 3, 5, 7, and 10 days after treatment using Abbott’s formula. The results revealed that oil formulations have significantly enhanced the aphicidal efficacy of B. bassiana by about 1.6 folds compared to aqueous preparations. This improvement may be contributed to the increased adhesion of the fungus on the insect’s cuticle and homogenous distribution of fungal spores on the leaf surface as well as providing a protecting layer against UV-light. In conclusion, oil formulations (horticulture /mineral oils) are one of the most promising technologies for enhancing efficacy of the entomopathogenic B. bassiana against aphids. mixing orange oil with B. bassiana has exerted a considerable mortality percentage against A. craccivora.}, keywords = {Beauveria bassiana,Mycoinsecticide,Aphis craccivora,Orange oil,star oil,sunflower oil,soybean oil}, url = {https://eajbsa.journals.ekb.eg/article_12481.html}, eprint = {https://eajbsa.journals.ekb.eg/article_12481_2d34e7f8da2378251f2573a8c78e5d52.pdf} } @article { author = {Abd El-Karim, Hamdi and Rahil, Ashraf and Rizk, Marguerite}, title = {Effects of Organic and Conventional Plantation of Chamomile On the Occurrence of Some Sucking Insect Pests and Their Natural Enemies In Fayoum Governorate, Egypt}, journal = {Egyptian Academic Journal of Biological Sciences.

This research aims to study the efficacy of Kaolin (clay mineral) foliar application on the development of whitefly Bemisia tabaci (Genndius) (Hemiptera: Aleyrodidae) population on tomato plants. Two field experiments were performed at Qalubiya governorate, Egypt through three successive seasons (2014, 2015 and 2016). The first experiment was carried out in 2014 to evaluate the reduction effect of two Kaolin concentrations (2.5% and 5% W/V)) compared with two recommended pesticides; Acetamiprid (Mospilan SP 20) and Orange oil (Prev-AM) on B. tabaci. The results revealed that the initial effect of Acetamiprid and kaolin 5% were superior in activity with 91.6% and 90.1% reduction in whitefly adults population. Similar efficacy for Acetamiprid and 5% Kaolin were found on nymphs (89% and 85.7% respectively). The second experiment was conducted to study the impact of repeated foliar applications of Kaolin; 2.5% and 5% (W/V), compared with the two insecticides; Acetamiprid (Mospilan SP 20) and Orange oil (Prev-AM), on population fluctuation of whitefly stages (adults and nymphs) during summer plantation of 2015 and 2016 seasons. For both studied seasons no significant differences were found between the main numbers of whitefly adults recorded on plants treated with either Acetamiprid (3.5 and 4.1 adult/leaf) or Kaolin 5% (4.6 and 5.0 adult/leaf).  Moreover, no significant differences were found between orange oil treatment (9.4 and 10.0 adult / leaf) and Kaolin 2.5% treatment (8.9 and 9.5 adult/leaf). Similar trends were obtained with whitefly nymphs where, Kaolin 5% and Acetamiprid had the same reduction effect. In conclusion, the use of Kaolin foliar application can be considered in a program of agricultural management since it can control a high percentage of whitefly; Kaolin particles act as a barrier repelling infestations.}, keywords = {Tomato whitefly,Bemisia tabaci,Kaolin foliar application,Non chemical pest control,Physical pest control}, url = {https://eajbsa.journals.ekb.eg/article_12486.html}, eprint = {https://eajbsa.journals.ekb.eg/article_12486_501898de0c05acbce5dd522ab603fb0c.pdf} } @article { author = {El Sattar, Sanaa and Doha, Said and El Hossary, Shabaan and El Sawaf, Bahira}, title = {A Simplified Identification key of Egyptian Sandfly Species}, journal = {Egyptian Academic Journal of Biological Sciences.

The karyotype of the holocentric chromosomes at meiotic metaphaseI for the non-irradiated and the irradiated adult males were examined by lightmicroscope. Fourteen chromosomes were observed at the meiotic metaphase I ofthe non-irradiated spermatogonial cells. The typical diploid number of the 14chromosomes was (12A + XY).
