文摘The outbreak of Cryptotympana atrata happened in a certain airport,Zhejiang Province in July 1999.Some airplanes were damaged.The biological habits of this insect,the causes of outbreak were studied.The author also suggested some measurements to control C.atrata which including artificial catching,physical control and chemical control.
