Laboratory Rearing of the Imported Cabbageworm
Webb, Susan; Shelton, Anthony
The imported cabbageworm (ICW), Artogeia rapae (L.) is one of New York's most serious pests of cabbage; studies related to its control are an important component of our research program. For instance, we have experimented with the use of a granulosis virus for management of ICW, and our laboratory has an ongoing program screening cole crops for resistance to several lepidopteran species including ICW. Because these studies all require a constant supply of disease-free eggs and larvae, we continuously rear the insects in the laboratory. Fortunately, although the ICW is a crucifer specialist, it can be reared on a wheat germ-based diet. The major requirements for successful culture are: (1) supplemental lighting in the greenhouse to provide conditions suitable for mating and oviposition, and (2) strict attention to measures designed to prevent disease in the population, and to prevent microbial contamination of the diet.
