Abstract

Surveys of parasites of Sylepta derogata (F.) on cotton at Ibadan, Nigeria, in 1979–80 showed that there were three larval parasites: Apanteles syleptae Ferrière, A. sagax Wlkn. and Charops sp. An average of 17·7% parasitism was recorded, and A. syleptae accounted for 98·6% of this. There were three pupal parasites: the chalcidid Brachymeria feae Masi, the ichneumonid Xanthopimpla sp. and the tachinid Cadurcia auratocauda (Curr.). Together, they caused an average of 31·7% parasitism. Xanthopimpla was the most abundant, while B. feae was of secondary importance.
