The crucifer flea beetle is a key economic insect pest of canola in the Northern Great Plains of North America. Most canola producers in Northern Great Plains rely on chemical insecticide seed treatments to protect their crops. Foliar chemical insecticides can be effective against P. cruciferae when treatments are made at the economic threshold of 25% feeding injury at the seedling stage. A focus in agriculture production is a shift toward more environmentally friendly pesticide products that provide efficacious pest control and are cost effective. To our knowledge, bioinsecticides have not been tested for crucifer flea control in canola. Therefore, we were interested in comparing bioinsecticides to chemical insecticides for crucifer flea beetle control in canola. In field research plots we compared the effect of commercial bioinsecticides of Beauveria bassiana , Saccharopolyspora spinsoa , azadirachtin, and kaolin, a clay, to the chemical insecticides thiomethoxam and bifenthrin. The chemical insecticides provided the best protection against flea beetle feeding at the research sites where the flea beetle population was high. SpintorŽ (Saccharopolyspora spinsoa ) is the only bioinsecticide that protected against flea beetle feeding injury and subsequent yield loss when compared to the foliar chemical bifenthrin (CaptureŽ) at research sites where the flea beetle pressure was low to moderate. SpintorŽ is currently registered for many other insect pests, including beetles, and appears to have potential in the crucifer flea beetle management scheme.
