STUDY ON THE BIONOMICS AND CONTROL OF Chondracris rosea rosea

Chondracris rosea rosea (De Geer) has one generation a year and overwinters as egg in the coastal areas of Fujing province. The peak ?period of its harm is from july to August. The control experiments in field show that 1000 times of 45% Rogor Tamaron oil or 1% 1605 pow-der is more than 95% for its contrl effect before three stage of the nymph of locust.
