Abstract
In 2007-2008, we examined the flight responses of
Monochamus titillator (F.) complex [
M. titillator, Monochamus carolinensis (Olivier), and any possible hybrids],
Momonchamus scutellatus (Say),
Monochamus clamator (LeConte),
Monochamus obtusus Casey, and
Monochamus mutator LeConte (Coleoptera: Cerambycidae) to multiple-funnel traps baited with and without host volatiles and bark beetle pheromones. Experiments were conducted in mature pine (
Pinus) stands in Alberta (Canada), and Arkansas, Arizona, California, Florida, Idaho, Michigan, Montana, New Hampshire, North Carolina, Ohio, Oregon, Tennessee, Utah, and Wisconsin (United States). At each location, traps were deployed in 10 replicate blocks of four traps per block. The trap treatments were: 1) blank control; 2) ipsenol and ipsdienol; 3) ethanol and α-pinene; and a quarternary blend of ipsenol, ipsdienol, ethanol, and α-pinene. All five species or species complex of
Monochamus preferred traps baited with the quaternary blend over all other treatments. The consistency of these results across such a large geographic area suggests that similar selection pressures may be acting on
Monochamus spp. in pine forests, regardless of variation in stand composition and climatic conditions. Our results suggest that multiple-funnel traps baited with the quaternary blend of ipsenol, ipsdienol, ethanol, and-pinene may be highly effective for monitoring various
Monochamus spp. in pine forests of North America, and may have utility in trapping and detection programs in North America and overseas.
