摘要

The production of coconut in Bangladesh is severely threatened by the invasive rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae). An experiment on potted coconut plants (12 to 18 months old) was conducted to evaluate widely practiced control options against RSW. The treatments imposed were yellow sticky trap, release of predatory ladybird beetle, Coccinella septempunctata (Coleoptera: Coccinellidae) and foliar spraying of biopesticides (neem oil) and synthetic insecticides (buprofezin, abamectin, pymetrozine, imidacloprid). Post treatment counts were taken on number of eggs, nymphs and adults per plant at 7 days after treatment application. Among the treatments, pymetrozine 50 WG showed highest mortality of RSW population followed by imidacloprid 20 SL treatment. The buprofezin 40 SC and neem oil 3% had less ovicidal impacts but causes significant death of RSW nymphs and adults. In contrast, the yellow sticky trap had less effect on reducing RSW population (lowest mortality) followed by abamectin 1.8 EC. Spraying of pymetrozine 50 WG was the most effective control measure to reduce number of eggs, nymphs and adults of RSW followed by application of imidacloprid 20 SL and buprofezin 40 SC.
