摘要
白僵菌冬季防治松毛虫，能使松毛虫在林分中带菌越冬。次年春季，松毛虫白僵病流行早，防治效果好，而且对松林有显著的保护作用。白僵菌可采用油剂、乳剂、水剂和粉剂防治，施菌量以１７．１─１８万亿个孢子／ｈｍ２为宜。
Controlling pine
caterpillars by Beauveria bassiana in winter can make the pine caterpillars hiber-nate with the
fungi in stands. The epidemic of white stiff disease for pine caterpillars will be early in the fol-
lowing spring, the control result will be good and it will have a significant protective effect on the
pinestands.The forms of oil agent, emulsion, water agent and powder of B. bassiana can be
adopted for controland the fungus application amount of 17.1×1012─18×1012 spores per ha is
suitable.
