The effect of imidacloprid on fecundity in twospotted spider mites, Tetranychus urticae Koch, was investigated in laboratory experiments using individual females on bean leaf discs. Mites were directly exposed to spray formulations of imidacloprid or fed on discs cut from a systemically treated bean plant. Imidacloprid-treated T. urticae produced 10-26% more eggs during the first 12 d of adult ...

Tetranychus macfarlanei is a potential threat to various economically important crops. Chemical control widely used this spider mite, but the exclusive reliance on chemical acaricides now being questioned, and entomopathogens are emerging as promising alternative. The efficacy of largely depends abiotic factors like temperature, humidity, rainfall etc. experiments were conducted determine effec...

The issue of entomopathogenic fungi’s prodigious rate reproduction plagues both academic research and clinical practice. Several production technologies preparations based on them are currently available. These medications appear to be liquid, powdery, dry, grainy. selection nutritional medium substrates, as well the identification ideal breeding conditions, crucial steps in manufacturing pesti...

Adult female twospotted spider mites, Tetranychus urticae Koch, reared on lima bean plants were moved to cucumber, maize, or new lima bean plants (the latter being a control) and evaluated after 24 h or 7 d for changes in susceptibility to three pesticides and in levels of related detoxification enzymes. The largest and most consistent changes were observed in mites feeding on cucumber. Suscept...

Inducible anti-herbivore defenses in plants are predominantly regulated by jasmonic acid (JA). On tomato plants, most genotypes of the herbivorous generalist spider mite Tetranychus urticae induce JA defenses and perform poorly on it, whereas the Solanaceae specialist Tetranychus evansi, who suppresses JA defenses, performs well on it. We asked to which extent these spider mites and the predato...
