Many species of Lepidoptera lay their eggs on to commercial crops where their caterpillars can cause extensive damage. Currently the primary biological control is the nematode, Steinernema carpocapsae, while the predatory bug Macrolophus and lacewing larvae will both feed on moth eggs as well as young caterpillar.
Pheromone traps can be used to monitor adult moth activity of a number of species. Lepinox Plus (Bacillus thuringiensis subspecies kurstaki) is a biopesticide spray with curative activity for caterpillar.
Steinernema carpocapsae - Contains the insect pathogenic nematode, Steinernema carpocapsae, as infective juveniles which seek out insect larvae and in some cases pupae.
Can be used to control overwintering stages of codling moth (Cydia pomonella), oriental fruit moth (Cydia molesta) and other caterpillar species. Also used for shore fly (Ephydridae) and can be used for large pine weevil control.
