Abstract: A survey of natural enemies of Diabrotica speciosa (Germ.) adults collected on different vegetable crops in Pelotas, RS (lat. 31° 52' S, long. 52° 21' W) was conducted. The most frequent natural enemies were the tachinid Celatoria bosqi Blanch., the braconid Centistes gasseni haw and the fungus Beauveria bassiana (Bals.) Vuill. The nematode Hexamermis sp. and the fungus Metarhizium anisopliae (Metsch.) Sorok. occurred at low levels. The lowest percentage of parasitism was observed in December (6.6%) and the highest in April (35.5%), with an yearly average of ca. 20%.
