Abstract
The high density of the field crickets Gryllus pennsylvanicus (Burmeister) and Nemobius fasciatus (DeGeer) under test trees in an unsprayed orchard, and the high mortality of apple-maggot pupae, Rhagoletis pomonella (Walsh), in test lots at the same time of year, suggested that crickets may have preyed heavily on the pupae and thus have constituted important mortality factors. Laboratory observations showed that crickets can detect, disinter, and consume apple-maggot pupae in simulated natural surroundings.Keywords
