Abstract : To test the efficacy of some chemical insecticides for the control of mango leafhoppers (Idioscopus spp.), field trials were done during the mango season 2003 at the mango orchards of Lac Research Station and Horticulture Centre, Kallyanpur, Chapai Nawabgonj, Bangladesh. Twelve insecticides, namely Asataf (acephate) 75 SP, Sicorin (cypermethrin) 10 EC, Sinothrin (cypermethrin) 10 EC, Cyperin (cypermethrin) 10 EC, Reeva (lamda-cyhalothrin) 2.5 EC, Cypercid (cypermethrin) 10 EC, Accord (cypermethrin) 10 EC, Delcis (deltamethrin) 2.5 EC, Sevin (carbaryl) 85 SP, Fencid (fenvalerate) 20 EC, Cypermer (cypermethrin) 10 EC and Fighter (lamda-cyhalothrin) 2.5 EC were evaluated at predetermined doses. Two sprayings, the first within 10 days of flowering and the second after one month of the first application were done. Considering the percent reduction (more than 80%) of the nymphal population over the pretreatment population of the mango leafhoppers and percent increased fruit retention over the untreated control, Accord 10 EC, Sinothrin 10 EC, Cypermer 10 EC, Fighter 2.5 EC, Sicorin 10 EC, Cyperin 10 EC, Cypercid 10 EC at the rate of 1 ml/litre of water; Asataf 75 SP at the rate of 5g/litre of water, Sevin 85 SP at the rate of 2 g/litre of water, Fencid 20 EC at the rate of 0.5 ml/litre of water and Delcis 2.5 EC at the rate of 0.5 ml/litre of water were the best among the tested insecticides for the effective control of mango leafhoppers.
