Nineteen compounds were evaluated in combination with a solution of acetic acid as baits for trapping the German yellowjacket, Vespula germanica (F.), the western yellowjacket Vespula pensylvanica (Sausssure), and the golden paper wasp Polistes aurifer Saussure. Compounds with three to six carbon chains or branched chains and with a hydroxy functional group were selected for testing based on their similarity to isobutanol. They were compared with isobutanol with acetic acid, which is a known wasp attractant. None of the compounds tested were superior to isobutanol when presented with acetic acid as a lure for these species of wasps. However, traps baited with either the S-(-)- or the racemic mixture of 2-methyl-1-butanol in combination with acetic acid captured similar numbers of both species of yellowjackets, compared with isobutanol with acetic acid. Polistes aurifer responded strongly to the S-(-)-enantiomer and to the racemic mixture of 2-methyl-1-butanol with acetic acid and not to the R-(+)-enantiomer with acetic acid.
评估了19种化合物与醋酸溶液混合作为诱饵，用于诱捕德国黄胡蜂（Vespula germanica (F.)）、西方黄胡蜂（Vespula pensylvanica (Sausssure)）和金纸巢黄蜂（Polistes aurifer Saussure）。基于与异丁醇的相似性，选择了具有三至六个碳链或支链且带有羟基官能团的化合物进行测试。将它们与已知的黄蜂引诱剂异丁醇和醋酸进行比较。当以醋酸作为这些黄蜂种类的诱饵时，所测试的化合物均不优于异丁醇。然而，与用异丁醇和醋酸作诱饵的陷阱相比，用S-(-)-2-甲基-1-丁醇或其外消旋混合物与醋酸组合作诱饵的陷阱捕获的两种黄胡蜂数量相似。金纸巢黄蜂对S-(-)-对映体以及2-甲基-1-丁醇与醋酸的外消旋混合物反应强烈，而对R-(+)-对映体与醋酸无反应。
