There are several types of spider mites, some which specialized to feed on certain crops, and they a major nuisance in agriculture. Predatory insects such as golden-eyes, semi-hardwings, cockroaches, predatory can successfully reduce the number mites. The type crop particular mite species have an impact how successful these predators are. Spider mites frequently encountered agricultural pest, t...

A bacterial isolate from soil, designated as TB-2125 had a unique pattern of multiple resistance to aminoglycoside antibiotics (AG) and produced new nucleoside antibiotics. Taxonomic properties of this strain fell into those of Bacillus circulans, providing unique characteristics such as strict susceptibility to acidic pH, motility of colony as well as multiple AG-resistance. Two new antibiotic...

as the host plants based on their physical and chemical characteristics can affect virulence of microbial control agents on the target pest and its natural enemies, therefore in the current study, the virulence of beauveria bassiana tv isolate at concentration 107 conidia/ml was evaluated against t. urticae female adults, on three different host plants; tomato, cucumber and strawberry. spray to...

C1A plant cysteine proteases are synthesized as pre-pro-enzymes that need to be processed to become active by the pro-peptide claves off from its cognate enzyme. These pro-sequences play multifunctional roles including the capacity to specifically inhibit their own as well as other C1A protease activities from diverse origin. In this study, it is analysed the potential role of C1A pro-regions f...

The experiment was conducted to study the effectiveness of four commonly used chemicals viz., deltamethrin, cypermethrin, malathion and sulphur against two-spotted spider mite (TSSM), Tetranychus urticae Koch on potted bean plants and on excised leaf discs. Mite population remained significantly lower in all treated plots except malathion treatment. The population of T. urticae differed signifi...
