Abstract
ABSTRACT Antennal sensilla were compared in parthenogenetic females and bisexual adults of rice water weevil, Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae), using scanning electron micrographs. The antenna of parthenogenetic females and of both sexes of bisexual reproductive weevils consisted of the scape, pedicel, and 6 flagellar segments. Females, regardless of mode of reproduction, had longer antennal segments than males. The 3 adult forms/genders can be correctly classified into their respective groups with a set of discriminant mathematical functions based on 4 morphological measurements of length or maximum width of segments of the antennae. For both sexes, 6 morphological sensilla types were found on the antennae, including hydrofuge scales I (hsI), trichoid sensilla (ts), 2 types of squamiform sensilla (ssI, ssII), tuft hairs (th), and Bohm bristles (Bb). No remarkable sexual differences in the types or distribution of sensilla were found on the antennae among parthenogenetic and b...
