Chaetonyx robustus (Scarabaeidae: Orphninae) – new natural host of Heterorhabditis bacteriophora (Rhabditida: Heterorhabditidae)
Journal Title: ZooNotes - Year 2014, Vol 57, Issue 0
Abstract
Heterorhabditis bacteriophora Poinar, 1976 was isolated from single larva of Chaetonyx robustus Schaum, 1862 (Scarabaeidae: Orphninae) from soil of a riverside habitat near town of Zemen, SW Bulgaria. Insects from the subfamily Orphninae are reported for the first time as natural hosts of heterorhabditids. In aboratory conditions larvae of C. robustus exhibited a low susceptibility to nematodes, which probably results from adaptation to avoid nematode invasion, arising from continuous coexistence in natural habitats.
