An observation on antennal of Lasiognatha cellifera Meyrick with scanning electron microscope

Abstract

In order to learn the types,morphology and distribution of antennal sensilla of female and male Lasiognatha cellifera Meyrick,we observed them by scanning electron microscopy( SEM). The results showed that an antenna of L. cellifera adults consisted of scape,pedicel,flagella and a flagella consisted of 61-68 subsegments,flagella length was 3 500-4 200μm,with the most types of sensilla. There were six types of sensilla on L. cellifera's antenna,including sensilla trichodea,sensilla squamiformia,sensilla coeloclnica,sensilla cavity,sensilla auricillica and sensilla basiconca. The sensillum trichodea were the most in number and distribution.
