摘要
为查明广西桉蝙蛾天敌寄蝇的种类、分布及其对桉蝙蛾的控制效果,2012年和2013年的1—5月在桉蝙蛾发生区采集桉树木段带回室内收集寄蝇成虫。共收集到寄蝇498头,经鉴定均为栗色舟寄蝇Scaphimyia castanea Mesnil;调查了38个县(市),有29个县(市)调查到寄蝇的分布,约占调查县(市)的76.32%。平均寄生率为8.09%,最高寄生率33.33%;寄蝇羽化后即可交配;寄蝇寄生桉蝙蛾幼虫,产卵方式为伪胎生型,寄蝇交配1周后,将卵产在虫包中,幼虫脱离母体后迅速侵入蝙蛾虫道中寻找寄主。
To clarify the species,distribution and control effect of tachinid flies parasitizing Endoclyta signifer in Guangxi,eucalyptus w ood sections w ere brought back from the occurrence area of E. signifer to collect tachinid flies betw een Jan. and May of 2012 and 2013. A total of 498 tachinid flies w ere collected,w hich were all identified as Scaphimyia castanea Mesnil. S. castanea distributed in 29 counties among the 38 counties investgated,accounting for 76. 32%; the average parasitization was 8. 09%,and the highest parasitization w as 33. 33%; S. castanea could mate immediately after the emergence and mainly parasitized the larvae of E. signifier. Its mode of reproduction was pseudo viviparity. S. castanea laid eggs one week after the mating,and the larvae rapidly searched and get into the host.
