Abstract

A grooved board trap was tested to detennine the effects of trap size (two sizes) and bait (apple pomace) on capturing the black vine weevil, Otiorhynchus sulcatus on raspberries, Rubus idaeus. Large traps (30 x 30 cm) caught significantly more weevils than small ones (15 x 15 cm). Large traps were also more sensitive in capturing weevils than small ones, which will be important when the weevil density is low. Apple pomace bait did not significantly enhance the attractiveness of grooved board traps to the black vine weevil. Grooved board traps may also be useful for weevil monitoring in other crops.

Key words: black vine weevil; board trap; raspberry; apple pomace
