RODRIGUEZ, Jinnay et al. Efecto patogénico del nemátodo parásito Strelkovimermis spiculatus en larvas del mosquito Culex quinquefasciatus en condiciones de laboratorio en Cuba. Rev Cubana Med Trop [online]. 2003, vol.55, n.2, pp. 124-125. ISSN 1561-3054.

The infective capacity of Strelkovimermis spiculatus Poinar and Camino, 1986, was evaluated under laboratory conditions for the first time in Cuba in order to introduce it as a new agent of biological control of mosquitoes of medical and epidemiological importance. The second stage larvae of Culex quinquefasciatus Say, 1823, were used and exposed to the infective juvenile parasites at different doses. It was observed a rise in the mean values of infestation and in the mortality percentage with the dose increase. Culex quinquefasciatus Say proved to be a good host and a dose of 7:1 will be optimum to attain high percentages of mortality and to obtain this parasite massively for its further evaluation under field conditions.
