( Elsevier Ltd. , 2013 , Article)The present study reports investigations on the insecticidal activity of the entomopathogenic bacterium Photorhabdus temperata K122 against the Mediterranean flour moth Ephestia kuehniella. Cultured in the optimized medium, ... -
Study of the Bacillus thuringiensis Vip3Aa16 histopathological effects and determination of its putative binding proteins in the midgut of Spodoptera littoralis
( Elsevier Inc. , 2011 , Article)The bacterium Bacillus thuringiensis produces, at the vegetative stage of its growth, Vip3A proteins with activity against a broad spectrum of lepidopteran insects. The Egyptian cotton leaf worm (Spodoptera littoralis) is ... -
Susceptibility of Agrotis segetum (noctuidae) to Bacillus thuringiensis and analysis of midgut proteinases
( Taylor & Francis , 2015 , Article)Seventy-eight Bacillus thuringiensis isolates were selected for a screening against the Lepidoptera species Agrotis segetum to search the higher insecticidal activity. In a preliminary bioassay, the spore-crystal mixture ... -
Vegetative insecticidal protein of Bacillus thuringiensis BLB459 and its efficiency against Lepidoptera
( Elsevier Ltd , 2017 , Article)Bacillus thuringiensis strain BLB459 supernatant showed a promising activity against Lepidopteran pests with extremely damages in the larvae midgut. Investigations of the genes that encode secreted toxin demonstrated that ...
