Microorganisms isolated from forest insects of British Columbia
Abstract
Pathogenic and non-pathogenic microorganisms including fungi, bacteria, viruses, miscrosporidia and nematodes were isolated from about 14,000 specimens representing 108 pest species of insects collected from British Columbia forests between 1949 and 1969. <i>Entomophthora</i> sp. and <i>Beauveria</i> sp were the most widely distributed fungal organisms isolated, occurring in 14 and 29 insect species, respectively. Nuclear polvhedrosis and granulosis viruses were isolated from 53 species, microsporida from 26, pathogenic bacteria from 12 and nematodes from 2 species. A new variety of <i>Bacillus thuringiensis</i>, viz. <i>canadensis</i>, was isolated from <i>Lambdina fiscellaria lugubrosa</i> (Hlst.) and a <i>Neophasia</i> sp. The largest numbers of species of microorganisms were found in <i>Melanolophia imitata</i> (Wlk.), <i>Malacosoma disstria</i> Hbn., <i>M. pluviale</i> (Dyar), <i>L. f. lugubrosa</i>, <i>Acleris variana</i> (Fern.), <i>Hyphantria cunea</i> Dru., <i>Choristoneura fumiferana</i> (Clem), <i>Orgyia pseudotsugata</i> (McD) and <i>Neophasia menapia</i> Feld.References
