The quantification of natural enemies actually living within a given crop is very important, because it helps in pest control decisions. Therefore a survey of natural enemies of Cerconota anonella (Sepp.) was carried out in a soursop crop between March,1997 and April,1998 at Maceió, AL (lat.9°S, long. 35°W), Brazil. The parasitism was defined by the ratio: the number biological forms of natural enemies and the biological forms of pests and parasitoids. The insects observed, in order of incidence, were: Apanteles sp. (Hymenoptera: Braconidae), Rhysipolis sp. (Hymenoptera: Braconidae) e Xiphosomella sp. (Hymenoptera: Ichneumonidae) . The lowest percentage of parasitism was found in October 1997 (6.6%) and the highest one in January 1998 (80.27%), with an annual average of 38.1%.
