Here, we describe several field experiments that evaluated potential problems with current methods of trapping cerambycid beetles using panel traps baited with synthesized pheromones. Positioning traps at least 5 m apart in linear transects was effective in preventing unbaited traps from intercepting beetles that were flying to baited traps, which would result in interference between treatments. There was no evidence that traps baited with a strong attractant drew beetles away from traps baited with weaker attractants, which would lead to the erroneous conclusion that the latter have no activity. Unbaited panel traps were minimally attractive to cerambycid beetles, and unlikely to intercept them passively in flight. Finally, dose-response experiments revealed that trap catch of cerambycids was positively associated with pheromone release rates. Overall, our results generally validated current methods of trapping cerambycids using traps baited with pheromones.
在此，我们描述了几项田间试验，这些试验评估了当前使用合成信息素诱捕天牛的方法存在的潜在问题。将诱捕器在线性样带中至少相隔5米放置，可有效防止未设诱饵的诱捕器拦截飞向设诱饵诱捕器的甲虫，否则会导致处理之间的干扰。没有证据表明用强引诱剂设诱饵的诱捕器会将甲虫从用较弱引诱剂设诱饵的诱捕器吸引过来，否则会得出后者没有活性的错误结论。未设诱饵的平板诱捕器对天牛的吸引力极小，不太可能在飞行中被动拦截它们。最后，剂量反应实验表明，天牛的诱捕量与信息素释放率呈正相关。总体而言，我们的结果普遍验证了当前使用信息素诱捕天牛的方法。
