Abstract:

The advances in utilization of entomogenous nematodes for control of forest pest insects are reviewed in this article.Entomogenous nematodes are an important biological control agent in depressing of the population of their host insects.Specially the nematodes of Mermithidae, Neotylenchidae, Steinernematidae and Heterorhabditidae are used on large scale, successfully controlling woodwasps, weevils, carpenter moths.The mass production techniques were introduced from Australia in 1985.It has been promoting the progress in control of insect pests with entomopathogenic nematodes in China.Various insect pests are tested in field trials in Beijing, Tianjin, Fujian, Hubei, Liaoning, Jilin and so on.The tested insects include Carposina niponensis, Atrijuglans hetauhei, Hoplocampa spp., Arbela bailbarana, Zeuzera multistrigata, Holcocerus insularis, Apriona germar, Aromia bungii, Pristiphora beijingensis, scarabs and so on.In the field trials the results indicate that entomopathogenic nematodes are the effective bio-control agents in the cryptic insect pests.
