摘要
落叶松红腹叶蜂是宁南山区的主要有害生物之一。本文通过在固原市原州区的水沟和叠叠沟林场用白僵菌粉和粉拟青酶等对落叶松叶蜂的生物防治试验,结果表明白僵菌菌粉防治虫茧和蛹的平均感染率74%;粉拟青酶防治虫茧和蛹的平均感染率82%。利用白僵菌粉和粉拟青霉可有效的防治落叶松红腹叶蜂。
Pristiphora Erichsonii Havtig is one of the major pest attacking forest. An experiment on biological control of Pristiphora Erichsonii Havtig by Beauveria bassiana and Paecilomyces fumosoroseus were conducted. The results showed that Beauveria bassiana generated infection rate of 74% on cocoon and chrysalis whereas Paecilomyces fumosoroseus did 82% on cocoon and chrysalis, indicating they both are effective to control Pristiphora Erichsonii Havtig.
