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...
متن کاملBollgard cotton and resistance of tobacco budworm (Lepidoptera: Noctuidae) to conventional insecticides in southern Tamaulipas, Mexico.
Insecticide susceptibility in tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), was determined for 8 yr (1991-2001) with larvae sampled from cotton in southern Tamaulipas, Mexico. Before 1996, when Bollgard cotton expressing the Cry1A(c) delta-endotoxin was introduced into the region, two important patterns were documented. The first was economically significant increases in r...
متن کاملField Persistence of Some Novel Insecticides Residues on Cotton Plants and Their Latent Effects against Spodoptera littoralis (Boisduval)
New insecticides that exhibited high compatibility with environment components are very promising substitutes for control of the economic insects. Simi-field experiments were conducted on profenofos and four novel insecticides viz., spinosad, emamectin-benzoate, pyridalyl and indoxacarb to investigate their efficiency and the field persistence of their residues against 4 instar larvae of the co...
متن کاملEfficacy of Some Insecticides Against Whitefly (Bemisia tabaci Genn.) Infesting Cotton under Field Conditions
Seven insecticides, viz. Megamos 20SL, Actara 25WG, Polo 500SC, Sitara 25WP, Nighaban 20EC, Thiodan 35EC and Confidor 200SL were evaluated at their field recommended doses for their efficacy against whitefly (Bemisia tabaci Genn.) on cotton, at the farmer’s field in Dera Ghazi Khan during 2007. The insecticides were applied at ETL’s of whitefly. All the test insecticides caused significant mort...
