Entomopathogenic nematodes can be considered effective biocontrol agents of pest insects in aquatic habitat. Larvae of Culex quinquefsciatus Say were exposed to infective juveniles of Heterorhabditis bacteriophora, H. indica, Steinernema carpocapsae, and S. feltiae under laboratory conditions. The bioassay studies revealed the suppressive role of H. bacteriophora and H. indica nematode in controlling the mosquito, C. quinquefasciatus. They successfully established themselves in the host cadaver and produced infective juveniles. On the other hand, both S. carpocapsae and S. feltiae failed to establish in the host larvae or attain significant host mortality values. This is the first report of parasitism of entomopathogenic nematodes isolates from Egypt against larvae of C. quinquefasciatus, with promising results. Therefore, further studies must be carried out to determine if these nematodes would be effective as autochthonous agents for the control of Culex sp. and other mosquitoes of sanitary interest.
