Recent Advances in the Integrated Management of the Pine Wood Nematode in China

Abstract

The main control strategies for pine wilt in China are use of intensive quarantines, clear cutting and methyl bromide fumigation of pines trees killed by the pine wood nematode (PWN, Bursaphelenchus xylophilus). As well, both aerial and ground sprays of fenitrothion insecticides can signifi cantly reduce tree death rates by killing the beetle vectors. Other effective treatments to control the pine sawyer beetle, Monochamus alternatus, a cerambycid beetle, include hot water treatment of the infected wood, and for affected logs and branches high temperature treatment, submerging in water and burying in soil, and direct trapping of adult, vector beetles using terpene-baited traps. However, because of the extensive areas of affected forests these methods do not give effective control (Xu et al. 1994a; Dwinell 1997).
