Graduate Theses and Dissertations
Insects in the genus Monochamus are medium to large-sized, wood-boring beetles whose primary hosts in the Northern Hemisphere are pine trees. These beetles interact with both conifer hosts and associated insects throughout their life history. Past research has demonstrated that Monochamus are saprophagic, but recent findings show that they may colonize healthy pine trees. To determine if southeastern Monochamus could colonize healthy pines, adult Monochamus were attracted to healthy shortleaf pine trees from May to September, 2014, using host volatiles, Ips bark beetle kairomones, and congeneric pheromones. Subsequent development of oviposited eggs from 18 host trees was monitored. The results …
