The life history and behavior of the flea beetle Phyllotreta pusilla Horn in Manitoba

Abstract

Flea beetles are represented in Manitoba by several species. Of those which attack cruciferae, Plyllortreta pusilla Horn is the most abundant, widespread and destructive. The life history and behavior of the various species are known in general from studies in other localities, but no records of similar studies in Manitoba have been found. The economic importance of P. pusilla in Manitoba makes a biological study particularly important. It was the purpose of this study (1) to present an illustrated description of the different life stages; (2) to determine the life cycle of the insect in Manitoba; and (3) to study the behavior and habits of the insect...
