Feeding damage by cabbage seedpod weevil (CSPW) [Cyrtorhynchus obstrictus (Marsham) (Coleoptera: Cuculionidae)], the most destructive pest of canola in north Alabama, may result in significant reduction in seed yield. CSPW is most attracted to canola at reproductive stage.  Early maturing canola lines enter the reproductive stage several weeks ahead of the conventional cultivars. The temporal asynchrony between early maturing and conventional cultivars provides an effective management tool in the control of cabbage seedpod weevil. This study evaluates early maturing canola lines as trap crops for CSPW.
