Cryptophlebia encarpa (Meyrick) (Lepidoptera: Tortricidae) as a pest of cacao pods in the northern province of Papua New Guinea
Cryptophlebia encarpa is a minor pest of cacao pods in the Norther Province of Papua New Guinea. The damage caused by this species has however become increasingly conspicuous in recent times following the control of other pod-damaging insects through the use of insecticides. The larvae feed on the epicarp and less frequently penetrate the mesocarp and feed on the endocarp of the cacao pod. Death of an attacked pod may result from penetration of the mesocarp by the larvae and subsequent fungal infection of the endocarp and seeds. High infestation levels are positively associated with increased abundance of large, maturing cacao pods, the abundance of which is characteristically seasonal. Under laboratory conditions, the duration of the larval stage is 13 to 15 days and the pupal stage 8 to 11 days. Mean adult longevity is 4.3 days.
