The effectiveness of a four-component "super lure" consisting of ethanol (E) and the cerambycid pheromones syn-2,3-hexanediol (D6), racemic 3-hydroxyhexan-2-one (K6), and racemic 3-hydroxyoctan-2-one (K8) on trap catches of Cerambycidae (Coleoptera) was determined in southeast United States with seven trapping experiments in 2011-2013. We captured 74 species of longhorn beetles in our three-year study. Ethanol significantly increased the mean catches of seven species and increased the number of cerambycid species detected. Traps with the "super lure" were effective for 8 of 13 species of Cerambycidae previously shown to be attracted to binary combinations of ethanol plus one of the three pheromones. However, the "super lure" was less effective for the remaining five species with catch reductions of 40-90% compared with combinations of ethanol and one or two of the pheromones. For example, K6 + K8 lures reduced catches of Anelaphus villosus (F.) in traps with E + D6 by 90%. Similarly, catches of Anelaphus pumilus (Newman) in traps with E + K6 + D6 were reduced by 50% with the addition of K8. Catches of Knulliana cincta (Drury) in traps with K6 + K8 lures were interrupted by D6, an effect negated by the addition of ethanol. Given the interruptive effects on trap catches of some species when lures are combined in a single trap, developing optimal lure blends to maximize detection efficacy will be a challenge for managers of detection programs for non-native invasive species of longhorn beetles.
在美国东南部，于2011年至2013年进行了七次诱捕实验，以确定由乙醇（E）和天牛性信息素顺式-2,3-己二醇（D6）、外消旋3-羟基己烷-2-酮（K6）以及外消旋3-羟基辛烷-2-酮（K8）组成的四成分“超级诱饵”对天牛科（鞘翅目）诱捕量的有效性。在我们为期三年的研究中，共捕获了74种天牛。乙醇显著提高了7种天牛的平均捕获量，并增加了检测到的天牛种类数量。装有“超级诱饵”的诱捕器对先前已证明会被乙醇与三种信息素之一的二元组合吸引的13种天牛中的8种有效。然而，“超级诱饵”对其余5种天牛的效果较差，与乙醇和一种或两种信息素的组合相比，捕获量减少了40%-90%。例如，在装有E + D6的诱捕器中，K6 + K8诱饵使绒毛小角天牛（F.）的捕获量减少了90%。同样，在装有E + K6 + D6的诱捕器中，加入K8后，矮小角天牛（纽曼）的捕获量减少了50%。在装有K6 + K8诱饵的诱捕器中，带纹窄颈天牛（德鲁里）的捕获量被D6干扰，加入乙醇后这种干扰作用被消除。鉴于当诱饵在单个诱捕器中组合时对某些物种诱捕量的干扰作用，开发最佳诱饵混合物以最大化检测效果将是外来入侵性天牛检测项目管理者面临的一项挑战。
