CAGNOLO, Susana R.  e  ALMIRON, Walter R.. Capacity of the terrestrial entomopathogenic nematode Steinernema rarum (Rhabditida: Steinernematidae) to parasite Culex apicinus larvae (Diptera: Culicidae). Rev. Soc. Entomol. Argent. [online]. 2010, vol.69, n.1-2, pp.141-145. ISSN 1851-7471.

Entomopathogenic nematodes can be considered effective agents for biocontrol, resulting innocuous for humans. Larvaeof Culex apicinus Philippi were exposed to infective juveniles of Steinernema rarum (OLI strain) under laboratory conditions, testing six doses (1:1, 5:1, 10:1, 15:1, 100:1, 400:1). An increasing percentage of mosquito larvae mortality was recorded with an increased dose. The highest percentage of mosquito larvae mortality (75%) was obtained with the dose 400:1. This is the first report of parasitism of an isolated of S. rarum from Córdoba against larvae of C. apicinus, 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 Linnaeus and other mosquitoes of sanitary interest in the country.
