Larval production from field-collected Carcinops pumilio (Coleoptera: Histeridae) following three starvation periods.
Carcinops pumilio (Erichson) were collected from high-rise, caged-layer poultry facilities using two trapping methods, a blacklight pitfall trap and a mesh-bottomed trap placed on poultry manure. Starvation for 14 d significantly reduced larval production during the first 3-d oviposition period regardless of trapping method. Beetles collected with blacklight traps and subsequently starved for 14 d had higher larval production in the third through fifth oviposition periods than those fed daily, indicating that lack of nutrition was a limiting factor in C. pumilio larval production. No differences were observed in larval production, after the first oviposition period, between the 14-d starved and daily fed groups collected with the mesh-bottom trap. In all blacklight-captured treatments, larval production was lowest during the first oviposition period with the largest differences found among the three starved treatments. Larval production in the 14-d starved treatment increased significantly during the later oviposition periods in mesh-bottom trap studies. Within the fed treatment, larval production was consistently greater among beetles collected with the mesh-bottom trap than among beetles collected with blacklight traps.
