Prey- and density-mediated dispersal in Carcinops pumilio (Coleoptera: Histeridae), a predator of house fly (Diptera: Muscidae) eggs and larvae. Academic Article

abstract

• Carcinops pumilio (Erichson) were collected using two trapping methods: a black light pitfall trap and a mesh-bottomed trap placed on poultry manure. C. pumilio collected with black lights and subsequently starved had a significantly higher dispersal rate during days 1-3 than fully fed groups. When densities of < 500 Caloglyphus berlesei (Michael) (Acarina: Acaridae) per 50 C. pumilio were provided, mite availability had a significant effect on dispersal of beetles captured with both black light traps and the mesh-bottomed trap during the day 1-3 period. Our results indicate that the availability of acceptable food sources can delay and possibly prevent dispersal by C. pumilio. Black light-captured beetles appeared to be in a state of dispersal when captured. A subset of dispersing beetles was present in groups captured with the mesh-bottomed trap.
