Rhopus nigroclavatus (Ashmead) and Pseudaphycus sp. (Hymenoptera: Encyrtidae):: Two parasitoids of the buffalograss mealybugs, Tridiscus sporoboli (Cockerell) and Trionymus sp.

Two encyrtid parasitoids, Rhopus nigroclavatus (Ashmead) and Pseudaphycus sp. were reared from the buffalograss feeding mealybugs, Tridiscus sporoboli (Cockerell) and Trionymus sp. Tn a rearing study, parasitism of adult female mealybugs by these two parasitoids was 29.64%, with an average emergence of 1.92 parasitoids per mealybug. The identification of these two encyrtid parasitoids provides a valuable first step for the development of a biological control program for managing mealybug infestations.
