| 摘 要： | 通过林间采样和室内养虫获取虫源,根据Dyar规律划分幼虫龄数,确定桑天牛幼虫有6龄,其中头壳宽度为最佳分龄结构。在确定幼虫龄数的基础上,对第1腹节背步泡突后横沟下方瘤突数、尾节刚毛数、上颚外侧刚毛数进行了观察统计,并对上述形态特征判别龄数准确性进行验证。结果表明:综合应用3项形态特征与Dyar规律划分的符合率为90.47%,上述形态特征可应用于桑天牛幼虫龄数的判别。 |

| Abstract: | Apriona germari larvaes were obtained via collecting in woodland and indoor rearing.In this study,larvae instar number were divided by Dyar’s law,and the results showed that larval stage comprised six instars and the head-width was the best instar-dividing structure.On the basis of instar-dividing,tubercle numbers on the transverse furrow downside of first abdominal dorsal ambulatory ampullae,setae numbers of abdominal telson and lateral setae numbers of mandible were used as morphological criterion.The accuracy of instar-dividing was researched by comparing with the Dyar’s law.The coincidence rate of two instar-dividing results was 90.47%.It is approved that the morphological criterion could be used in the instar-dividing of A.germari larvae. |
