摘要:

室内在器皿内和半自然条件下,利用花绒寄甲对锈色粒肩天牛进行寄生性试验,最佳效果分别达80%和86.67%。林间在山东泰安、聊城等地选取5处被锈色粒肩天牛危害的国槐行道树作为试验地,释放花绒寄甲成虫、卵块对锈色粒肩天牛幼虫进行生物防治试验。以天敌释放前后被害株虫口数为依据,对花绒寄甲的防治效果进行评价。林间各处理最佳防治效果为: 单纯释放花绒寄甲成虫、卵块后,株虫口减退率分别为72.23%和71.67%,同时释放花绒寄甲成虫及卵块时,其株虫口减退率为82.64%。但3者间差异不显著。 林间释放花绒寄甲成虫和卵块,对锈色粒肩天牛均有良好的控制效果。

Abstract:

Dastarcus helophoroides (Fairmaire) ( Coleoptera: Bothrideridae) is an important insect natural enemy for controlling Apriona swainsoni (Hope) ( Coleoptera: Cerambycidae). Adults and eggs of D. helophoroides were released in laboratory and semi-field condition to control A. swainsoni in Tai’an and Liaocheng of Shandong Province, and the optimum efficiency was up to 80% and 86.67%, respectively. Before releasing the natural enemy and after releasing it, the populations of A. swainsoni larvae per tree were investigated. Based on the investigation, the optimal controlling effect was as follows: After released just adults, or eggs, or a mixture of them outdoor, the reducing rate of the population of A. swainsoni larvae per tree was at 72.2%, 71.6%, 82.64%, respectively. However, the reducing rate have had no significant difference among the three treatments. Results showed that releasing adults and eggs of D. helophoroides in field could be an efficient measure for controlling A. swainsoni.
