摘要
Fenitrithion was sprayed with high pressure sprayer in pine forest where Bursaphelenchus xylophilus (PWN) occurred in middle May and middle June respectively. The results showed that the adults of Monochamus alternatus (JPS) were killed and the pine tree mortality rate was very low. There was no dead tree in sprayed Pinus massoniana forest in 4 years but 6% dead rate in the CK forest in Fuyang City. The mortality rate in the sprayed Pinus nigra forest in 2 years was below 1%, but 30% in the CK forest in an island of Zhoushan City. Large number of adults of JPS reared with Pinus nigra branches which sprayed fenitrothion (200×～600×) died in 24 hours, all died in 8 days, but only 13.3% died in the CK. Applying in large area, the control effect was obvious.
