Assessment of losses in honey yield due to the chalkbrood disease, with reference to the determination of its economic injury levels in Egypt.
In Egypt, the chalk brood (CHB) disease caused by the fungus, Ascosphaera apis Maassen started again infesting the honeybee, Apis melifera L (Hymenoptera: Apidae) colonies after a cessation pause ofExpand
Integrated crop management of the lesser date moth Batrachedra amydraula Meyr. (Lepidoptera: Cosmopteridae) infesting some date-palm varieties in Egypt.
Evaluated agricultural practices on the incidence of the lesser date-moth, Batrachedra amydraula Meyr, in El-Beheira Governorate, Egypt revealed that tolerance of Sammany to the infestation was due to relatively higher wax content than that of either Hayany or Halawy, causing a considerable reduction in its infestation.

In vivo toxicity of ring-substituted dibenzoylhydrazines against larval stages of the beet armyworm, Spodoptera exigua, and their action on in vitro cultured imaginal discs found that both nonsteroidal ecdysone agonists induced premature and lethal molting, and caused the same effect as 20-hydroxyecdysone in vitro.

Joint action of quercetin with four insecticides on the cotton leaf-worm larvae, Spodoptera littoralis Boisd. (Lep. : Noctuidae) in Egypt.
The present results proved the synergistic effect of quercetin when combined with four insecticides, namely, profenofos (organophosphates), deltamethrin (pyrethroid), and tebufenozide et hexaflumuron as insect growth regulators against the studied insect-pest. Expand
A novel approach for the management of the chalkbrood disease infesting honeybee Apis mellifera L. (Hymenoptera: Apidae) colonies in Egypt.
Thymol substance at the rate of 2% showed also a great success in managing the CHB disease, as it is the cheapest material and proved to increase the brood nest as well, and thymol has other uses in the field of apiculture. Expand
Biological performance of quercetin on the cotton leaf-worm larvae, Spodoptera littoralis Boisd. (Lep., Noctuidae) and prevailing natural enemies in the Egyptian cotton fields.
New approaches for the management of the cotton leafworm Spodoptera littoralis Boisd are developed within an IPM program, that include synthetic insecticides rationalization, and maximiziation the role of the biological control agents. Expand
Efficacy of some plant oils alone and/or combined with different insecticides on the cotton leaf-worm Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) in Egypt.
The comparative toxic efficiency of the tested insecticides proved that Permethrin was the most effective one, giving LC50 values of 2.92 and 1.53 ppm after 72 and 96 h post treatment, indicating an efficient continuous persistence of nervous toxicity. Expand
