Abstract
The effects of granular insecticides to the vegetable leafminer, Liriomyza sativae Blanchard, the serpentine leafminer, L. trifolii (Burgess), and the tomato leafminer, L. bryoniae (Kaltenbach), on kidney bean leaves were evaluated at 20°C under a 15L9D photoregime. Among 8 insecticides tested on second instar larvae, cartap and thiamethoxiam were highly toxic on the three Liriomyza species. None of the granular insecticides suppressed the number of oviposition and feeding punctures enough in any of the three Liriomyza species. Cartap, clothianidin, dinotefuran, nitenpyram, and thiamethoxiam were more toxic on the three Liriomyza species eggs.
