摘要

Apriona germari larvae were obtained via sample collection in woodland and indoor rearing. In this study,larval instars were divided by Dyar’s law,and the results showed that the larval stage of A. germari comprised six instars,while the width of head capsule was the best instar-dividing structure. On the basis of instar division,tubercle numbers on the transverse furrow downside of first abdominal dorsal ambulatory ampullae,seta numbers of abdominal telson and lateral seta numbers of mandible were observed and statistically calculated. The accuracy of instar-dividing was verified by comparing with the Dyar’s law. The coincidence rate of two instar-dividing results was 90. 47%. It is approved that the above morphological features could be used in instar division of A. germari larvae.
