Variation in tolerance to Bacillus thuringiensis among and within populations of the spruce budworm (Lepidoptera: Tortricidae) in Ontario.

Journal of economic entomology - 1 Feb 1995

van Frankenhuyzen K, Nystrom C W, Tabashnik B E

Abstract excerpt

Variation in tolerance to Bacillus thuringiensis Berliner subsp. kurstaki (strain HD-1-S-1980) among and within populations of the spruce budworm, Choristoneura fumiferana (Clemens), was assessed in the laboratory. Force-feeding assays using offspring of females collected as pupae from nine locations throughout Ontario and from a laboratory colony (DCF) demonstrated limited variation in tolerance among...
