Abstract
Effect of foaming application of insecticides on insect pests of cabbage and eggplant was investigated in a field in Osaka Prefecture. With the foaming application of acetamiprid, the densities of green peach aphid, Myzus persicae (Sulzer), turnip aphid, Lipaphis erysimi (Kaltenbach) and common white, Pieris rapae crucivora Boisduval larvae on cabbage were effectively reduced, and the effect was equal with the spraying application of the insecticide. With the foaming application of cypermethrin, the density of P. rapae crucivora larvae on cabbage was effectively reduced, but the effect was lower than the spraying application of the insecticide. With the foaming application of acetamiprid, the density of cotton aphid, Aphis gossypii Glover on eggplant was effectively reduced, and the effect was equal with the spraying application of the insecticide. The results suggest that the foaming application of insecticide shows good control against insect pests on vegetables.
