Diamondback moth. Biology and Integrated Pest Management in Canola

Abstract

The diamondback moth, Plutella xylostella (Linnaeus), belongs to the order Lepidoptera and family Plutellidae. It is an important, occasional pest of canola in North Dakota. The immature stage, or larva, injures the leaves, buds, fl owers and seed pods of canola. In the North Dakota, the severity of infestation varies considerably from year to year and depends on the numbers and seasonal timing of migrating moths. The most recent outbreaks occurred in 2001 and 2007, primarily in the northcentral and northeastern regions of North Dakota.
