【Abstract】 The entomopathogenic nematode, Steinernema carpocapsae (strain Agriotos) was evaluated for its potential to control the vegetable beetle, Colaphellus bowringi Baly, in the soil. The mortality of 3rd and 4th instar larvae was about 90 per cent under the constant temperature of 25℃ and 75%～80% under the natural temperature after nematodes were applied. The parasite rate of nematodes to the 1st～2nd instar larvae and pupae was 50% to 70%, but the adults of the beetle were not infected by the nematodes.更多还原
