[Pathogenic effect of the parasite nematode Strelkovimermmis spiculatus (Nematoda Mermithidae) in larvae of mosquito Culex quinquesfasciatus (Diptera Culicidae) under laboratory conditions in Cuba].
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.
