COMPARATIVE ANALYSIS OF SENSILLA ON ANTENNAE AND MOUTHPARTS OF LARVAE IN TWO SPECIES OF DITRYSIAN MOTHS (LEPIDOPTERA)

Abstract

Systematics encompasses two more narrowly defined but highly interdependent fields. The first is taxonomy and the second field is phylogenetics. In modern systematics, taxonomy aims to reflect evolutionary history. The morphological traits of immature stages remain largely unresolved for a vast majority of the lepidopteran species worldwide, although they have potential to be applied in lepidopteran classification and systematic studies. The larval instars in Lepidoptera are signature examples of agricultural pests. The present study deals with SEM investigation of ultrastructure of different instars of two lepidopteran pest species i.e., Somena scintillans Walker 1856 and Trabala vishnou Lefebvre 1827. These findings will not only help in enriching taxonomic database but will also act as an aid for future studies aimed at devising pest control methods
