Feeding preference of native subterranean termites (Isoptera: Rhinotermitidae: Reticulitermes) for wood containing bark beetle pheromones and blue-stain fungi.

摘要

Surprisingly little research has been conducted to investigate interactions between subterranean termites and bark beetles. Facilitative interactions between these organisms could easily alter stand dynamics and impact wood utilization strategies. A series of American Wood Protection Association Standard E1-09 "choice tests" were carried out to determine the feeding preference of Reticulitermes flavipes Kollar (Isoptera: Rhinotermitidae) for blue-stained sapwood and sapwood impregnated with various bark beetle pheromones. Reticulitermes flavipes exhibited a feeding preference for both air-dried and kiln-dried blue-stained sapwood, unstained sapwood treated with frontalin, and air-dried blue-stained sapwood treated with a 0.02% solution of both frontalin and endo-brevicomin. The implications of these results are far reaching, with particular relevance to forest health, ecology, and utilization.
