摘要
【目的】管氏肿腿蜂(Scleroderma guani Xiao et Wu)是防治天牛类害虫较为有效的寄生性天敌,研究明确山东省潍坊地区利用管氏肿腿蜂防治双条杉天牛的最佳释放时间和释放量对天牛类害虫的防治具有重要意义。【方法】采用室内和林间试验相结合的方法,对管氏肿腿蜂防治双条杉天牛(Semanotus bifasciatus Motschulsky)效果进行测定。【结果】室内试验结果表明,释放管氏肿腿蜂可有效寄生双条杉天牛幼虫,管氏肿腿蜂的寄生率随释放量的增加而提高;林间试验结果表明,山东潍坊地区利用管氏肿腿蜂防治双条杉天牛的最佳时间为6月,其校正寄生率达50%左右,林间以10000头/hm2释放量防治双条杉天牛,校正寄生率为50.93%~54.53%。【结论】释放管氏肿腿蜂能有效抑制双条杉天牛危害,可作为生物防治双条杉天牛的重要措施进行推广应用。
[Objective]To evaluate the control effect of Sclerodermus guani on Semanotus bifasciatus,the S.guani female adults were released on the S.bifasciatus larvae in forests.[Method]The control effect of S.guani on Semanotus bifasciatus Motschulsky was measured by indoor and interforest experiments.[Result]The results showed that the effect of releasing tubifex wasps to control the first instar larvae of S.bifasciatus was correlated with the amount of release,and the parasitism rate of S.bifasciatus larvae increased with the increase of the amount of release.The release of S.guani should be carried out during early June to late June in Weifang area to release the best effect of bees,with the passage of time reducing the effectiveness of prevention,and the later the releasing time,the worse the effects.The corrected parasitism rates could reach to 50.93%-54.53%,when mass release of S.guani insects at the quantity of 10000 per hm^(2) into a cypress forest in Qingzhou.[Conclusion]The results show that the release of S.guani can effectively inhibit the damage of the S.bifasciatus,and can be promoted as an important measures for the biological control of the S.bifasciatus.
