An updated data on the bionomics of pomegranate fruit borer, Deudorix epijarbas (Moore, 1858) (Lepidoptera: Lycaenidae), infesting pomegranates in Kashmir

Abstract

<p>Pomegranate fruit borer,<em> Deudorix epijarbas</em> (Moore, 1858) (Lepidoptera: Lycaenidae) is a destructive pest of pomegranate affecting the quality as well as quantity of its fruits. The pest and its other allied species are nuisance to pomegranate cultivation throughout India, particularly in hilly state of Jammu & Kashmir. The aim of present investigation was to study the bionomics of pomegranate fruit borer in laboratory, which included the studies on its morphometry and extent of different developmental stages in the life cycle of pest, for developing a sound management plan against it. The results revealed that the eggs are laid by females singly on fruits, stalks, leaves and flower buds. On hatching, emerging larva bores in to fruits and feed on its pulp thus rendering them unfit for trade. The pest passed through five larval instars of different duration and the total larval period was 32.20 ± 1.87 (SD) days. The larval stage was followed by pupal stage which lasted for 9.50 ± 1.84 (SD) days. Furthermore, the longevity of adult male and female butterflies was recorded as 9.20 ± 1.73 (SD) and 13.20 ± 1.43 (SD) days respectively. The study thus provides information necessary for development and implementation of different control strategies in IPM of pomegranate fruit borer.</p>
