Sensilla on the Wings of <i>Eurydema dominulus</i> (Scopoli)

Abstract

Eurydema dominulus (Scopoli), a phytophagous insect and a pest of many plants. The external morphology of the sensilla on the wings were observed using scanning electron microscope. Based on their morphological structure, different five types of sensilla were distinguished: sensilla trichoidea, sensilla chaetica, sensilla basiconica, sensilla campaniformia and sensilla ampullacea. These sensilla can be related to have mechanosensory, chemosensory and proprioceptive functions. The possible roles of these sensilla are also discussed.
