- Sawfly, Arge xanthogaster (Hymenoptera: Argidae), is a major pest of Rosa sp. in Meghalaya, India. Antennae are the most important sensory organs for sensing host plants, food selection, mates and site selection for oviposition. To understand the role of sensory organs in various biological behaviours of both the male and female A. xanthogaster, we studied the sensilla present on their antenna using the scanning electron microscopy. Based on external morphology, six sensillar types were observed including sensilla trichodea (I, II, III, IV, V, VI, VII), sensilla chaetica (I, II, III), sensilla basiconica (I, II), sensilla coeloconica (I, II), sensilla ampullacea and Böhm’s bristles. Sensilla trichodea I, II and sensilla basiconica I were found only in male whereas sensilla chaetica II, III were found only in female. Significant difference of sensilla trichodea III and VI in length between two sexes were observed. Putative functions of all the sensillar types were discussed based on their external morphology.
