We determined the response of the small southern pine engraver, Ips avulsus (Eichhoff); eastern fivespined ips, Ips grandicollis (Eichhoff); sixspined ips, Ips calligraphus (Germar); and pine engraver, Ips pini (Say) to the pheromones (+/-)-ipsenol, (+/-)-ipsdienol, and lanierone in the southeastern United States. Catches of I. avulsus and I. grandicollis to baited multiple-funnel traps were increased by (+/-)-ipsenol and (+/-)-ipsdienol in Florida, Georgia, Louisiana, and North Carolina. In all four localities, the highest numbers of I. avulsus were caught in traps baited with the combination of (+/-)-ipsenol, (+/-)-ipsdienol, and lanierone. In Florida, the highest numbers of I. grandicollis were captured in traps baited with the combination of (+/-)-ipsenol and (+/-)-ipsdienol (with or without lanierone). In the remaining three localities, the largest catches of I. grandicollis occurred in traps baited with (+/-)-ipsenol alone or the combination of (+/-)-ipsenol and (+/-)-ipsdienol (with or without lanierone). (+/-)-Ipsdienol was the only consistent attractant for I. calligraphus and I. pini. Attraction of I. pini in North Carolina to (+/-)-ipsdienol-baited traps was synergized by lanierone but interrupted with (+/-)-ipsenol. The interruptive effect of (+/-)-ipsenol on attraction of I. pini to (+/-)-ipsdienol was negated by lanierone. (+/-)-Ipsdienol was attractive to black turpentine beetle, Dendroctonus terebrans (Olivier), in Florida but not North Carolina, whereas (+/-)-ipsdienol was attractive to I. calligraphus in Louisiana, Georgia, and Florida. Both (+/-)-ipsenol and (+/-)-ipsdienol affected catches of Gnathotrichus materiarus (Fitch) in North Carolina. Trap catches of Hylurgops rugipennis pinifex (Fitch), Hylastes salebrosus Eichhoff, and Hylastes tenuis Eichhoff were unaffected by the pheromone treatments. The combination of (+/-)-ipsenol, (+/-)-ipsdienol, and lanierone may be a cost-effective general lure for I. avulsus, I. grandicollis, and I. pini.
我们在美国东南部测定了南方小松树小蠹（Ips avulsus (Eichhoff)）、东部五齿小蠹（Ips grandicollis (Eichhoff)）、六齿小蠹（Ips calligraphus (Germar)）和松树小蠹（Ips pini (Say)）对信息素（±）-异松油烯、（±）-异长叶烯和拉尼尔酮的反应。在佛罗里达州、佐治亚州、路易斯安那州和北卡罗来纳州，（±）-异松油烯和（±）-异长叶烯增加了用诱饵多漏斗诱捕器捕获的南方小松树小蠹和东部五齿小蠹的数量。在所有这四个地点，用（±）-异松油烯、（±）-异长叶烯和拉尼尔酮组合诱饵的诱捕器捕获到的南方小松树小蠹数量最多。在佛罗里达州，用（±）-异松油烯和（±）-异长叶烯（有或没有拉尼尔酮）组合诱饵的诱捕器捕获到的东部五齿小蠹数量最多。在其余三个地点，捕获到的东部五齿小蠹数量最多的是用单独的（±）-异松油烯或（±）-异松油烯与（±）-异长叶烯（有或没有拉尼尔酮）组合诱饵的诱捕器。（±）-异长叶烯是六齿小蠹和松树小蠹唯一一致的引诱剂。在北卡罗来纳州，拉尼尔酮增强了松树小蠹对（±）-异长叶烯诱饵诱捕器的吸引力，但（±）-异松油烯会干扰这种吸引力。拉尼尔酮消除了（±）-异松油烯对松树小蠹对（±）-异长叶烯吸引力的干扰作用。（±）-异长叶烯在佛罗里达州对黑脂大小蠹（Dendroctonus terebrans (Olivier)）有吸引力，但在北卡罗来纳州没有，而（±）-异长叶烯在路易斯安那州、佐治亚州和佛罗里达州对六齿小蠹有吸引力。（±）-异松油烯和（±）-异长叶烯都影响了北卡罗来纳州的Gnathotrichus materiarus (Fitch)的诱捕量。信息素处理对皱翅材小蠹（Hylurgops rugipennis pinifex (Fitch)）、粗糙材小蠹（Hylastes salebrosus Eichhoff）和细材小蠹（Hylastes tenuis Eichhoff）的诱捕器捕获量没有影响。（±）-异松油烯、（±）-异长叶烯和拉尼尔酮的组合可能是一种对南方小松树小蠹、东部五齿小蠹和松树小蠹具有成本效益的通用诱饵。
