Abstract

Behavioral differences between a Conophthorus beetle attacking jack pine shoot tips and the red pine cone beetle, C. resinosae Hopkins, were studied. In field experiments the red pine cone beetle attacked cones and shoots of both pines but preferred cones over shoots and red pine cones over jack pine cones. The jack pine tip beetle attacked both jack pine and red pine snoots, but no progeny appeared in red pine shoots. In laboratory tests, the red pine cone beetle survived equally well in vapors of simulated red and jack pine shoot resin, while the jack pine tip beetle survived best in the jack pine resin vapor. The jack pine tip beetle is described as a new species, Conophthorus banksianae McPherson.
