APPLICATION OF NUCLEAR POLYHEDROSIS VIRUS TO CONTROL BRUCE SPANWORM (LEPIDOPTERA: GEOMETRIDAE)
Published online by Cambridge University Press: 31 May 2012
Extract
A polyhedrosis virus was found in collections of Bruce spanworm, Operophtera bruceata (Hulst), larvae from two locations in British Columbia in 1957 (O. N. Morris, pers. comm.). Bruce spanworm was prevalent in the Maritime Provinces and Quebec in 1963 and 1964 and a polyhedrosis virus was credited with terminating this outbreak (Forbes et al. 1964, 1965; Martineau 1964, 1965). A detailed examination of the virus from Quebec showed that it was a singly-embedded (unicapsid) nuclear polyhedrosis virus (Smirnoff 1964) which is classified as Baculovirus subgroup A (Matthews 1979).
