Interpretive Summary: Dung beetles (Coleoptera: Scarabaeidae) are beneficial insects that play a major role in nutrient cycling, soil aeration, and biological control of pests, i.e. flies, that breed in manure. Loss of habitat, pesticide usage, and conventional agricultural practices have reduced their numbers, and their conservation is of growing concern. In the process of developing lures for the exotic nilgai antelope (host of cattle fever ticks), we discovered that one of the lures was highly attractive to dung beetles. We are publishing this result, because the lure could be used to efficiently collect dung beetles for relocation to ranches where they are needed. In our study we describe the lure and the many species of dung beetles collected.

Technical Abstract: Dung beetles (Coleoptera: Scarabaeidae) play a major role in nutrient cycling, soil aeration, and biological control of pests and parasites that breed in manure. Habitat fragmentation, pesticide usage, and conventional agricultural practices threaten dung beetle diversity, and their conservation is of growing concern. This study from August to October 2016 on the East Foundation, Santa Rosa Ranch, Kenedy County, TX investigated the comparative effectiveness of three chemical attractants, viz., screwworm lure, volatile fatty acids, and citronella oil to attract dung beetles. The screwworm lure attracted large numbers of beetles, but the other two attractants were not attractive to dung beetles. Morphological identification of 16 adult specimens confirmed Phanaeus vindex MacLeay, family Scarabaeidae (eight); Canthon pilularius L., family Scarabaeidae (five); and Nicrophorus carolinus L., family Silphidae (three), indicating the dung beetles were very attracted. Screwworm lure might be used to efficiently attract large numbers of dung beetles for relocation to areas where the species have been impacted.
