Extract

During a 1981 study on possible insect vectors of a yeast in Saskatchewan mustard crops, several incidental observations of attack by the western damsel bug, Nabis alternatus Parshley, on adults of the flea beetle Phyllotreta cruciferae (Goeze) were made near Oxbow in the southeastern part of the province. This is the fourth record of insect predation on crucifer-feeding flea beetles in the Canadian prairie provinces. Previous records involved the beetle Collops vittatus Say (Gerber and Osgood 1975), a big-eyed bug, Geocoris bullatus (Say) (Burgess 1977), and larvae of the green lacewing, Chrysopa carnea Stephens (Burgess 1980).
