SEX DIFFERENTIATION IN THE PUPAE AND ADULTS OF IPS SEXDENTATUS (COLEOPTERA: SCOLYTIDAE)1
Published online by Cambridge University Press: 31 May 2012
Abstract
Adult sexing characters were found by comparing the arrangements of spines on the elytral declivity. Callows were distinguished by observing the male vas deferens through the semi-transparent pronotum. In pupae, sexing characters were found to be located in the posterior abdominal segment of both sexes.
