Dung beetles of the subfamily Scarabaeinae are notable for their coprophagous, or dung eating, behavior. They feed on animal dung as adults, use the resource as a part of reproduction, and when their eggs hatch the larvae feed on that dung as well. However, a species of dung beetle native to Oklahoma is just as comfortable using animal matter, such as fur, feathers, and carrion, as they are using dung. Deltochilum gibbosum, the humpbacked dung beetle, is a large (> 2 cm) dung beetle that displays this feeding behavior. A beetle that can perform the ecosystem service of nutrient recycling using both dung and carrion is not only ecologically important but is also valuable to cattle operations looking to keep their pastures healthy. Since Deltochilum gibbosum can utilize both dung and carrion, they would need to have a gut microbiome suited for both resources. However, the microbiome of these beetles has never been examined. We acquired eight Deltochilum gibbosum, four male and four female, from the Insect Adventure. Two of the males and two of the females were fed on pig dung, while the other beetles were fed using dead laboratory mice. After staying on their target diet for a period of four weeks, the beetles were dissected, and their guts were preserved in a freezer in ethanol. The DNA was extracted using a DNeasy Plant Pro Kit and the associated process. A PCR test will be performed on the extracted DNA. This data will allow us to get an idea of the microbiome of these beetles while also determining if there are any differences between the beetles fed on dung and those fed on carrion. We hypothesize that the microbiome of Deltochilum gibbosum fed on carrion will be different than the microbiome of those fed on dung.
