Winter and spring greenhouse skirt membrane and the entrance of the two 60 mesh insect nets, can prevent the opening of the membrane when the tobacco powder into the ventilation, reduce the shed and the following year exposed. Third, in the greenhouse with dichlorvos smoke agent, steamed seedbeds, after the 60 mesh insect nets cover nursery. One week before transplanting, 10% imidacloprid was used to irrigate the roots 1000 times. Where conditions permit, nursery sheds and production sheds are separated. Fourth, when there are adults starting to occur in the shed, 20cm30cm yellow plates are trapped to kill the adults. Use waste fiberboard or cardboard to cut into 20cm30cm long strips, coat with yellow paint, and apply a layer of No. 10 motor oil, use 20-40 pieces per acre, hung in rows or between strains.
