Abstract
The genus Conogethes is a large, taxonomically complex cosmopolitan
moth taxon. To date, 24 species have been identified by DNA bar codes
and deposited in the Barcode of Life Data Systems (BOLD) (http://www.
boldsystems.org). Type locality of Conogethes punctiferalis is India, so
many closely allied species may be included but taxonomic revision of
them has been neglected for a long time. Integration of several approaches
like conventional taxonomy, DNA bar code, electrophysiological and be-
havioral responses of adults and larvae, host–plant relationship patterns,
hybridization experiments, biochemical analysis, and analysis of and re-
sponses to pheromone components of Conogethes reared on castor and
cardamom confirmed that the populations belong to two different spe-
cies. Bioecology and management of Conogethes have been well stud-
ied. More than 31 alternate host plants for the borer have been recorded.
Therefore, it has better adaptation in the cultivated ecosystems. An in-
tegrated approach involving nontoxic chemicals is desired as currently
mostly insecticides are applied to suppress this pest.

Introduction

The fruit and shoot borer Conogethes (= Di-
chocrocis) punctiferalis mainly occurs in tropi-
cal and subtropical countries (Pena et al. 2002 )
and is distributed in Asia and Australia. Larvae
of this crambid moth are typically polyphagous
pests attacking more than 120 wild and culti-
vated diversified plants, namely, peach, chestnut,
