Extract

The bertha armyworm, Mamestra configurata Wlk., is a periodic pest of rape in western Canada. After a massive outbreak of the species during 1971 and 1972, investigations on the insect were intensified in many laboratories. A technique for rearing the larvae on a semi-defined diet was developed by our Winnipeg-based group and has been used successfully to rear 21 consecutive generations of M. configurata in the laboratory (Bucher and Bracken 1976). Our current culture originated from a few pupae field-collected in Alberta and has been carried through 21 generations without addition of new stock.
