摘要： Apanteles cypris is an endoparasitoid of rice pest Cnaphalocrocis medinalis. To better understand its host location mechanism, we examined the external morphology of antennal sensilla of A. cypris via scanning electron microscopy. The antennae of male and female A. cypris were filiform in shape, which consist of scape, pedicel, and flagellum with 18 antennomeres. Eleven types of sensilla were recorded in both sexes, including two types of chaetica sensilla, trichodea sensilla without pore, basiconica sensilla I with a tip pore, basiconica sensilla II with wall pores, basiconica sensilla III with a mastoid at the tip, coeloconica sensilla with apparent fingerlike projections, campaniform sensilla with a sprout tip pore, clavatea sensilla, smell pore, and placodea sensilla (PLA) with the multiporous cuticular structure. We also compared the morphology, number, and distribution of the sensory receptors between the two sexes. The length and width of the antennae on the males were significantly greater than that of females. In addition, males of A. cypris showed a larger number and a higher density of PLA compared to females. The morphology and structure of these sensilla were compared to that found in other braconid wasps, and their possible functions in host location were discussed. These observations could facilitate future studies on the biology of olfaction in A. cypris. Microsc. Res. Tech. 74: 1199-1208, 2011. (C) 2011 Wiley Periodicals, Inc.
