贵州省云斑天牛生物学特性研究

Research on Biological Characteristics of Batocera lineolata Chevrolat in Guizhou Province

云斑天牛是近年来发生和影响比较严重的蛀干害虫,主要危害核桃、杨树等经济树种。它以幼虫在树皮的木质部蛀食,导致树木衰弱死亡。为了深入了解该害虫,课题组采用定期到林间调查研究的方法,明确了贵州省云斑天牛在核桃树上的生物学特性。同时,还发现了两种对云斑天牛幼虫或蛹具有较高寄生或捕食能力的天敌昆虫。研究结果将为今后贵州省云斑天牛的防治提供一定的理论依据。

Batocera lineolata Chevrolat was an important wood-boring beetle attacking Juglans regis, Populus spp. and other economic species. Its larvae fed on the shallow under the bark. In order to further understand this insect pest, the biological characteristics of B. lineolata were found out by the investigation method. Meanwhile, two species of insects with higher parasitic or predation abilities to B. lineolata were found. These findings provided theoretical support for B. lineolata control in Guizhou Province.
