Entomopathogenic Microorganisms in the Foci of the Gypsy Moth (Lymantria dispar L.) in Nut-Fruit Forests of the South of Kyrgyzstan

摘要

In the nut-fruit forests of the south of Kyrgyzstan the population of the gypsy moth (Lymantria dispar L.) is significantly regulated by the nucleopolyhedrovirus. In 2005-2007, half of all dead caterpillars died due to viruses. At the same time bacterial infection caused by Bacillus thuringiensis resulted in the 31.2% mortality rate of the herbivore, and mycotic and mixed bacterial-viral infection, in about 20%. It is revealed that the virulence of the Central Asian strains of the nucleopolyhedrovirus is higher as compared with that of the West Siberian strains.
