Abstract: | ![]() Nematodes are known to parasitise all major invertebrate groups in soils, and it has been assumed that their host finding relies on attraction to chemical cues. We studied movement of three species of insect-parasitic nematodes, Steinernema carpocapsae, Steinernema feltiae and Heterorhabditis megidis in response to chemical and vibrational cues. All species showed strong, significant taxes towards the vibrations. We also show that in soils, the utility of chemical cues as attractants is substantially reduced by the presence of organic matter. |
