摘要：选取6个松褐天牛危害的马尾松林样地,释放寄生性天敌花绒寄甲的卵和成虫。通过调查天敌释放前后被害株数和单株虫口数2个指标对花绒寄甲的防治效果进行评价,同时,采用室内和林间罩网寄生试验相结合的方法分析花绒寄甲对松褐天牛幼虫的寄生情况。在释放花绒寄甲卵和成虫后对当年松褐天牛的寄生防治效果显示:在释放花绒寄甲卵的3个试验林中,平均株虫口校正减退率为48.54%,平均被害株校正减退率为63.07%;在释放花绒寄甲成虫的3个试验林中,平均株虫口校正减退率为47.00%,平均被害株校正减退率为68.00%,二者差异不显著。说明林间释放花绒寄甲卵和成虫均对松褐天牛有良好的控制效果。室内试验中,释放花绒寄甲卵和成虫后,不同胸径受害木段中松褐天牛幼虫被寄生的数量比例变化较大,5～8cm胸径的木段中寄生率最高,达72.41%,显著高于10～15cm和>18cm胸径木段的49.52%和49.06%;分别在5,7和9月释放花绒寄甲卵和成虫,寄生率分别为68.50%,21.63%和30.29%,5月份的寄生率显著高于7月和9月。利用花绒寄甲防治松褐天牛具有良好的控制效果,以5月份释放天敌效果最好,可在生产中推广应用。
The pine sawyer, Monochamus alternatus （Coleoptera： Cerambycidae） , is the most important pest of pine Pinus massoniana throughout China. In this study, the parasitoid Dastarcus helophoroides （Coleoptera： Bothrideridae） eggs and adults were released in six plots of the pine forests for controlling M. alternatus. The control effect was evaluated by two indexes, i.e. , infested trees number and the pest larvae number in a host tree. Meanwhile,the parasitism rate of this parasitoid to its host was measured in indoor mesh and field mesh. Results showed that, releasing both eggs and adults was able to effectively control M. alternatus. In three plots of releasing the parasitoid eggs, the mean adjusted reduced rate of the pine sawyer larvae per tree was 48.54% , and the mean adjusted reduced rate of infested trees was 63.07%. In three plots of releasing the parasitoid adults, mean adjusted reduced rate of the pine sawyer larvae per tree was 47.00% , and the mean adjusted reduced rate of infested trees was 68.00%. The controlling effects by releasing adults of the parasitoid were a little better than that by releasing eggs of the parasitoid, without significant difference between them. The parasitoid responded differentially to DBH of 5 -8 cm, 10 - 15 cm, or 〉 18 cm pine sawyer - infested cutlogs. The highest parasitism rate was 72.41% in DBH of 5 -8 cm cutlogs, significantly higher than the others. During three periods （ May, July, September） of releasing the parasitoid, the parasitism rates of the pine sawyer larvae orderly were 68.50% , 21.63% and 30.29% , respectively. These findings determined that controlling larva of M. alternatus by releasing D. helophoroides to the forest in May was feasible, which is a new technology in biocontrol method.
