Abstract

The effects of three fertilizers (fresh cow manure, composted manure, and urea) were determined on the virulence of Steinernema carpocapsae (Weiser) against the greater wax moth, Galleria mellonella (L.). Nitrogen levels were standardized among fertilizer treatments at two levels (280 and 560 kg ha−1). Urea and fresh manure decreased nematode virulence in laboratory experiments. In field experiments, however, only the fresh manure treatment reduced nematode virulence. In both laboratory and field experiments, composted manure did not affect nematode virulence. Fertilizer effects on virulence of S. carpocapsae were more rapid in a soil with reduced organic matter than in a soil with higher levels of organic matter. Factors causing reduced nematode virulence are discussed.
