Abstract

Pheromone-baited traps located close to both host and nonhost crowns were more attractive than traps located between crowns for bothC. occidentalis Freeman andC. retiniana (Walsingham) at both 10 m and at 1.5 m above the ground. At 10 m height, traps located in host foliage were more attractive than those located in nonhost foliage, but at 1.5m height there was no significant difference. These results were obtained for both dense and sparse populations ofC. occidentalis and sparse populations ofC. retiniana. We conclude that the tree species on which a virgin female is located is not an important factor restricting mating between closely relatedChoristoneura spp. Also, the tree species on which a trap is located may not be an important factor that must be standardized in developing pheromone monitoring systems forC. occidentalis andC. retiniana.

摘要

性信息素诱捕器靠近寄主和非寄主树冠的位置比位于树冠之间的位置对西松大小蠹 Freeman 和云杉大小蠹（Walsingham）更具吸引力，无论是在 10 米还是 1.5 米的高度。在 10 米的高度，位于寄主枝叶中的诱捕器比位于非寄主枝叶中的诱捕器更具吸引力，但在 1.5 米的高度没有显著差异。这些结果对于西松大小蠹的密集和稀疏种群以及云杉大小蠹的稀疏种群都适用。我们的结论是，处女雌虫所在的树种不是限制亲缘关系密切的 Choristoneura 种之间交配的重要因素。此外，位于诱捕器上的树种可能不是开发西松大小蠹和云杉大小蠹性信息素监测系统时必须标准化的重要因素。
