Pea leaf weevils (Sitona lineatus L.) are a new pest threatening pea acres in Alberta. Feeding damage occurs in spring when weevils emerge from shelterbelts and alfalfa fields. Egg laying is believed to start immediately and most economic damage likely occurs from larvae that find their way to feed on the nitrogen fixing rhizobium nodules of the plant. The scale of economic damage is currently being assessed and is potentially disastrous to pea and faba bean acres. High infestation levels were observed in Southern Alberta during the 2007 growing season. This paper looks at trap crops, foliar applications, seed treatments, surveys and research.
