| Abstract: | A lure based on the proportional composition of monoterpenes inD. micans larval frass and deployed in Theysohn slot traps was highly attractive toR. grandis released in the field. The relative response to frass and lure was consistent over a range of doses, and behavior close to traps baited with either lure or frass appeared to be similar. The monoterpenes, formulated with antioxidant, appear to be stable over several weeks when released from proprietary reservoir and wick “air fresheners.” The lure may be of value in monitoring predator populations. |
