| phloeophagous and predaceous insects responding to synthetic pheromones of bark beetles inhabiting white spruce stands in the great lakes region. | tree killing and saprophytic bark beetles exert important ecological and economic roles in north american spruce forests. chemical signaling among bark beetles, and responses by associate insects such as predators and competitors, have significant effects on the population dynamics and ecology of this community. synthetic pheromones of primary (tree killing) and secondary (saprophytic) bark beetle species and blank controls were tested using multiple funnel and lower stem flight traps in white s ... | 2003 | 12921443 |
| landing patterns of phloem- and wood-feeding coleoptera on black spruce of different physiological and decay states. | we examined landing patterns of phloeophagous and xylophagous coleoptera among trees and snags of different physiological and decay states in a pure open-canopy black spruce stand in boreal canada to study prelanding host selection mechanisms in the absence of nonhost volatiles. sticky traps were used to capture insects landing on high- and low-density natural snags (i.e., wood density), girdled trees, living trees, and stovepipe controls. patterns were generally weak, with high within-group var ... | 2009 | 19508789 |
