Abstract
The occurrence of ambrosia beetle Euplatypus parallelus (Fabricius) (Coleoptera: Curculioninae: Platypodinae) infestation on cashew (Anacardium occidentale L.) is reported for the first time from Goa, India. Most of the infested trees were either previously attacked by cashew stem and root borer Plocaederus ferrugineus (Coleoptera: Cerambycidae) or were pruned trees. The visible symptoms of attack include appearance of numerous round bore holes on the tree trunk and branches, and extrusion of fibrous dust frass on the tree trunk and in loose piles at the base of the tree. Large numbers of larvae, pupae and adults were observed in the galleries of the affected trees. Adult beetles measure 4.0–4.3 mm in length and are brown in color, having long and slender bodies with yellow hairs. They have a characteristic feature of absence of pores on the pronotum. Male and female insects were identified based on the elytral declivity.
