Abstract

In 2007-2008, we examined the flight responses of Monochamus titillator (F.) complex [M. titillator, Monochamus carolinensis (Olivier), and any possible hybrids], Monochamus 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 4) a quaternary 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, andα-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.

Plain Language Summary

Woodboring beetles can have serious economic effects on the forest products industry, by causing extensive damage to lumber and by leading other countries to introduce restrictions on Canadian wood products. Development of an effective lure trap would be useful in monitoring programs to detect these beetles, both in forests and in ports where wood products are imported and exported. This work focused on testing a new combination of semiochemicals (sex odours) to better sample woodboring beetles in the genus Monochamus that affect pine forests across North America. We compared the attractiveness of a 4-component blend of odours to more commonly used 2-component blends. We showed that the 4-component blend was a far more attractive lure for several Monochamus species and should be the lure of choice in monitoring programs. This trap would thus improve monitoring programs for woodborers.
