摘要：【目的】确定利用花绒寄甲防治松褐天牛的最佳释放条件。【方法】采用L16(45)正交试验设计,选取成虫释放密度、释放方法、释放时间及卵释放密度、释放时间等影响因素,每因素设4个水平,进行正交试验,以寄生率为考察指标,确定释放花绒寄甲的最佳条件,并对最佳条件进行验证。【结果】各因素对花绒寄甲寄生松褐天牛寄生率影响的大小顺序为:成虫释放时间>成虫释放密度>卵释放时间>卵释放密度>成虫释放方法。花绒寄甲的最佳释放条件为:在3月初每个松褐天牛蛀孔通过随机法释放花绒寄甲成虫1头,在5月初每个松褐天牛蛀孔释放花绒寄甲卵40粒。【结论】确定了花绒寄甲的最佳释放条件,在该条件下,花绒寄甲对松褐天牛的寄生率可达87.17%。
【Objective】 The study was to obtain the optimization conditions of releasing Dastarcus helophoroides against Monochamus alternatus.【Method】 With parasitism rate as an indicator,L16（45）of the orthogonal test design was used to obtain the optimization conditions of releasing D.helophoroides to analyze adults release density by selecting the density of adults and eggs,time and method factors（each factor set four levels）,and verify the optimal conditions.【Result】 Results showed that the influence of various factors on parasitism was in the order of：adult release timeadult release densityegg release timeegg release densityadult release method.The optimal release condirion of adult was releasing D.helophoroides in the ratio of 1∶1（adult∶entrance hole） on early march by the uniform release method.The optimal release density of egg was 40∶1（egg∶entrance hole）,and the optimal egg release time was early May.【Conclusion】 The release conditions were optimized,under in these conditions,the parasitism of D.helophoroides against M.alternatus parasitism rate can achieve 87.17%.
