EVALUATION OF INSECTICIDES AGAINST COTTON APHID, 2005

Efficacy of different insecticides against aphid on brassica juncea

A field experiment was conducted to find out and compare the efficacy of Pyriproxyfen, Nitenpyram, Carbosulfan and Chlorpyrifos against aphid on Brassica juncea variety (Bahawalpur Raya) during Rabi 2016-17 at Regional Agricultural Research Institute, Bahawalpur, Pakistan. After 72 hours of treatment carbosulfan, nitenpyram and pyriproxyfen showed statistically similar results. Aphid population...

The joint action of destruxins and botanical insecticides (rotenone, azadirachtin and paeonolum) against the cotton aphid, Aphis gossypii Glover.

The joint action of destruxins and three botanical insecticides, rotenone (Rot), azadirachtin (Aza) and paeonolum (Pae) against the cotton aphid, Aphis gossypii, was bioassayed. In laboratory experiment, several synergistic groups of destruxins with botanical insecticides were found by means of Sun's Co-toxicity Coefficients (CTC) and Finney's Synergistic Coefficient (SC). The best synergistic ...

Arthropod MAnAgeMent evaluation of toxicity of Selected Insecticides against thrips on Cotton in Laboratory Bioassays

Adult vial technique (AVt) and spray table bioassays were conducted to evaluate toxicity of selected insecticides against immature and adult thrips, Frankliniella spp. (thysanoptera: thripidae). In AVt, technical insecticides comprised of organophosphates (dicrotophos and methamidophos), spinosyn (spinosad) and neonicotinoids (thiamethoxam and imidacloprid) were used. the LC50 values for contac...

Evaluation of soil-applied systemic insecticides against cabbage aphid,brevicoryne brassicae and resultant survival of the primary parasitoid diaeretiella rapae on cabbage

Molecular screening of insecticides with sigma glutathione S-transferases (GST) in cotton aphid Aphis gossypii using docking

Glutathione S-transferases (GSTs) are one of the major families of detoxifying enzymes that detoxifies different chemical compounds including insecticides in different insect species. Among the GST subclasses, sigma GSTs are found to be the most abundant and conserved among different insect orders. These GSTs are found to play an important role in lipid peroxidation as well as detoxification. C...
