【 摘 要 】

Surveys were conducted from 2011 to 2015 in cashew plantations to document the parasitoids of cashew leaf miner. Three eulophid parasitoids, viz., Chrysocharis sp., Closterocerus sp. and Aprostocetus sp. were recorded for the first time as parasitoids on the larvae of Cashew Leaf Miner, Acrocercops syngramma Meyrick (Lepidoptera: Gracillariidae).  Among the parasitoids, Chrysocharis sp. was dominant recording 99.0 % abundance.  The parasitism of leaf miner larvae was observed from September onwards, which reached its peak during November coinciding with the population of leaf miner larvae.  Chrysocharis sp. was found to be a solitary parasitoid, completing its life cycle within the mine of leaf miner and emerging as an adult.  Parasitization was noticed only on the third and fourth instar leaf miner larvae but not on the first and second instar larvae. In cashew plantations, leaf miner parasitism ranged from 37 to 58% by Chrysocharis sp.
