Occurrence of Parasitoid, Leiophron Sp. (Hymenoptera: Braconidae), on Adults of Helopeltis antonii Signoret in Cashew

Helopeltis antonii is a major pest of cashew, cocoa, neem, guava and pepper in the old world tropics. Survey for parasites identified a parasitoid, Leiophron sp. (Hymenoptera: Braconidae), on adults of H. antonii. The parasitism was low (1.3%), of which 59.4% was observed during the month of June. S...
