Significant research has been devoted to the development of semiochemical repellents for mountain pine beetle Dendroctonus ponderosae Hopkins. Several formulations of the beetle's antiaggregation pheromone verbenone (4,6,6‐trimethylbicyclo[3.1.1]hept‐3‐en‐2‐one) are registered to protect pine trees and stands. We compared the efficacy of verbenone and Verbenone Plus for protecting individual lodgepole pine Pinus contorta Dougl. ex Loud. and small stands of P. contorta from mortality attributed to D. ponderosae. Verbenone Plus is a blend of semiochemicals [(−)‐verbenone, acetophenone, and (E)‐2‐hexen‐1‐ol + (Z)‐2‐hexen‐1‐ol] originally developed to inhibit aggregation of western pine beetle D. brevicomis LeConte. It is the only effective semiochemical repellent that protects ponderosa pine P. ponderosa Dougl. ex Laws. from mortality attributed to D. brevicomis, but has yet to be registered or commercialized. Both verbenone and Verbenone Plus were effective for protecting individual P. contorta and small stands of P. contorta from mortality attributed to D. ponderosae. Verbenone alone was as effective as Verbenone Plus. An obstacle to the broader use of semiochemical repellents for the management of bark beetles is the relatively high cost and specificity of the semiochemicals involved. A semiochemical repellent with efficacy across multiple bark beetle species and hosts, such as Verbenone Plus, would be desirable, assuming the additional components are not cost‐prohibitive or limit registration.

马鞭草酮和马鞭草酮和非寄主挥发物的混合物保护黑松免受山松甲虫（鞘翅目：仙茅科）的影响

重要的研究致力于开发山松甲虫 Dendroctonusponderosae Hopkins 的信息化学驱虫剂。甲虫的抗聚集信息素马鞭草酮（4,6,6-三甲基双环[3.1.1]hept-3-en-2-one）的几种配方已注册用于保护松树和林分。我们比较了马鞭草酮和 Verbenone Plus 保护个体黑松 Pinus contorta Dougl 的功效。前大声。和 P. contorta 的小林分归因于 D.ponderosae 的死亡率。Verbenone Plus 是一种化学信息素 [(-)-verbenone、苯乙酮和 (E)-2-hexen-1-ol + (Z)-2-hexen-1-ol] 的混合物，最初开发用于抑制西松甲虫的聚集D. brevicomis LeConte。它是保护黄松 P.ponderosa Dougl 的唯一有效的化学信息素驱虫剂。前法律。从归因于 D. brevicomis 的死亡率，但尚未注册或商业化。马鞭草酮和 Verbenone Plus 均可有效保护个体 P. contorta 和小型 P. contorta 林分免于 D.ponderosae 造成的死亡。Verbenone 单独与 Verbenone Plus 一样有效。将化学信息素驱避剂广泛用于树皮甲虫管理的一个障碍是所涉及的化学信息素相对较高的成本和特异性。假设附加成分不会造成成本过高或限制注册，那么需要一种对多种树皮甲虫物种和宿主有效的信息素化学驱虫剂，例如 Verbenone Plus。contorta 和 P. contorta 的小林分来自 D.ponderosae 的死亡率。Verbenone 单独与 Verbenone Plus 一样有效。将化学信息素驱避剂广泛用于树皮甲虫管理的一个障碍是所涉及的化学信息素相对较高的成本和特异性。假设附加成分不会造成成本过高或限制注册，那么需要一种对多种树皮甲虫物种和宿主有效的信息素化学驱虫剂，例如 Verbenone Plus。contorta 和 P. contorta 的小林分来自 D.ponderosae 的死亡率。Verbenone 单独与 Verbenone Plus 一样有效。将化学信息素驱避剂广泛用于树皮甲虫管理的一个障碍是所涉及的化学信息素相对较高的成本和特异性。假设附加成分不会造成成本过高或限制注册，那么需要一种对多种树皮甲虫物种和宿主有效的信息素化学驱虫剂，例如 Verbenone Plus。
