Abstract

Abstract. 1. The presence and quantity of honeydew, produced by the, cereal aphid, Sitobion aveme (Fab.), on the time Coccinella seprempunctara L. larvae spent searching ears of wheat and on the number of aphids eaten, was investigated.2. In the presence of honeydew larvae spent longer searching the ears, resulting in a greater exploitation of prey than in the absence of honeydew.3. Larvae did not respond to differences in the amount of honeydew, so that the arrestment response would not result in aggregation in areas of high prey density.
