Great Lakes Entomologist. 35:71-78 Interpretive Summary: Because of concerns with adverse environmental and human health effects of many pesticides in use for controlling insects, new methods are needed to control insect pests of agricultural crops. Natural chemical attractants for insect pests are useful for trapping and killing targeted species. Researchers at the USDA-ARS Yakima Agricultural Laboratory are developing chemical attractants for several insect pests of tree fruits, including yellowjackets and paper wasps that are pests in apple and pear orchards, as well as vineyards. It was determined in collaborative studies with other researchers at Oral Roberts University that nine different species of these social wasps can be trapped with two different types of chemical attractants and that the wasps that are related toxonomically respond similarly to the chemical attractants. This new information is helpful in efforts to manage particular species that are pests by indicating which lures should be used for different types of wasps.
Technical Abstract: Nine species of social wasps were captured in traps baited with acetic acid, isobutanol, heptyl butyrate and combinations of acetic acid and either isobutanol or heptyl butyrate. Three yellowjacket species in the Vespula rufa species group were captured in traps (Vespula acadica [Sladen], Vespula consobrina [Saussure], Vespula vidua [Saussure]). They responded similarly, with attraction only to heptyl butyrate. Three yellowjacket species in the Vespula vulgaris species group were also captured in traps (Vespula vulgaris [L.], Vespula flavopilosa Jacobson, Vespula maculifrons [Buyyson]). They responded similarly, with attraction primarily to the combination of acetic acid and isobutanol. The bald-faced hornet, Dolichovespula maculata [L], was attracted to acetic acid and was more strongly attracted to the combination of acetic acid and isobutanol. The aerial yellowjacket, Dolichovespula arenaria (Fabr.), was attracted to isobutanol and was more strongly attracted to the combination of acetic acid and isobutanol. These results add to our understanding of how to target various species of social wasps with chemical lures.
