We assessed attraction of pine engraver, Ips pini (Say) (Coleoptera: Curculionidae; Scolytinae), to pheromone-baited funnel traps treated with repellent semiochemicals in ponderosa pine, Pinus ponderosa var. scopulorum Engelm., forests in northern Arizona. Treatments included: 1) baited control (B, ipsdienol + lanierone), 2) 70 g of SPLAT Verb (a flowable, biodegradable formulation containing 10% verbenone, ISCA Technologies Inc., Riverside, CA, USA) + B, 3) 70 g of SPLAT Verb + (E)-2-hexen-1-ol+(Z)-2-hexen-1-ol + acetophenone + B, 4) 7.84-g verbenone pouch (Product #3413, Synergy Semiochemicals Corp., Delta, British Columbia, Canada) + B, and 5) 7.84-g verbenone pouch + (E)-2-hexen-1-ol+(Z)-2-hexen-1-ol + acetophenone + B. In total, 472 I. pini were collected. Trap catches were highest in baited traps and declined significantly with the addition of both formulations of verbenone. Traps treated with SPLAT Verb caught significantly fewer I. pini and male I. pini than those treated with verbenone pouches. The addition of (E)-2-hexen-1-ol+(Z)-2-hexen-1-ol + acetophenone to SPLAT Verb and the verbenone pouch had no effect on trap catch. Verbenone has potential as an effective tool for protecting P. ponderosa trees and slash from I. pini in northern Arizona, but the addition of (E)-2-hexen-1-ol+(Z)-2-hexen-1-ol + acetophenone to verbenone is unwarranted.
我们评估了松雕象鼻虫（Ips pini（Say））（鞘翅目：象甲科；象甲亚科）对引诱剂诱捕器的吸引力，这些诱捕器在亚利桑那州北部的辐射松（Pinus ponderosa var. scopulorum Engelm.）森林中用驱避半化学物质处理过。处理方法包括：1）诱饵对照（B，ipsdienol + lanierone），2）70 g 的 SPLAT Verb（一种可流动、可生物降解的制剂，含有 10% 的马鞭草烯酮，ISCA Technologies Inc.，美国加利福尼亚州河滨市）+ B，3）70 g 的 SPLAT Verb +（E）-2-己烯-1-醇+（Z）-2-己烯-1-醇+苯乙酮+B，4）7.84 g 马鞭草烯酮袋（产品号 3413，Synergy Semiochemicals Corp.，加拿大不列颠哥伦比亚省三角洲市）+ B，和 5）7.84 g 马鞭草烯酮袋+（E）-2-己烯-1-醇+（Z）-2-己烯-1-醇+苯乙酮+B。总共收集了 472 只 I. pini。诱捕器的捕获量在有诱饵的诱捕器中最高，随着两种马鞭草烯酮制剂的添加，捕获量显著下降。用 SPLAT Verb 处理的诱捕器捕获的 I. pini 和雄 I. pini 明显少于用马鞭草烯酮袋处理的诱捕器。向 SPLAT Verb 和马鞭草烯酮袋中添加（E）-2-己烯-1-醇+（Z）-2-己烯-1-醇+苯乙酮对诱捕器的捕获量没有影响。马鞭草烯酮作为保护亚利桑那州北部的 P. ponderosa 树和 slash 免受 I. pini 侵害的有效工具具有潜力，但向马鞭草烯酮中添加（E）-2-己烯-1-醇+（Z）-2-己烯-1-醇+苯乙酮是不必要的。
