Attraction of male Collops vittatus in the field by caryophyllene alcohol
Environmental Entomology 10 (3), 301-304
Abstract: Caryophyllene compounds were tested as attractants for Collops vittatus (Say), a predacious beetle found in Arizona cotton fields. Caryophyllene alcohol was 10 x more attractive than caryophyllene oxide, a compound previously found to be attractive. Caryophyllene alcohol attracted only male beetles and these oriented to the source from a downwind direction. Cotton dental rolls containing 0.1 g of caryophyllene alcohol were attractive for 4 weeks under field conditions. The dental roll baits in delta traps were used to monitor populations of C. vittatus in cotton and alfalfa fields near Phoenix. Caryophyllene alcohol is a useful attractant for survey and ecological studies of C. vittatus.
