Available in PDF, EPUB and Kindle. Book excerpt: Canola and other oilseed Brassica species are important oilseed crops in the northern Great Plains of the U.S. and Canada. As a cool season crop, canola adds diversity to cropping rotation systems. The crucifer flea beetle, Phyllotreta cruciferae Goeze, and the striped flea beetle, Phyllotreta striolata, are the most serious insect pests of canola. Crucifer flea beetle is the dominant flea beetle pest of canola. Adult flea beetles emerge in the spring and feed on the cotyledons and true leaves. When they emerge in large numbers, they can devastate a seedling canola field quickly; therefore, timely monitoring and management of this pest is important. Control costs for flea beetles in oilseed Brassica crops often exceed $300 million annually in North America.
