[Infective capacity of the parasitic nematoda Romanomermis iyengari (Welch, 1964) (Nematoda: Mermithidae) in mosquito larvae in natural conditions].

: The effectiveness of the parasitic nematoda Romanomermis ivengari (Welch, 1964) was proved in 3 breeding sites of Anopheles albimanus (Wiedman, 1821) and Culex Nigripalpus (Theobald, 1901) and 2 spillways for 2 oxidation ponds with Culex quinquefasciatus (Say, 1823) larvae, in the Isle of Youth. The results of the experiments showed the infesting capacity of this nematoda species with 80-100% parasitism in A. albimanus and C. nigripalpus larvae, and 75-80% mortality for C. quinquefasciatus. Besides, the recycling capacity of R. invengari, after its introduction, was proved, confirming its possible use in the control of mosquito larvae of medical-epidemiological importance in the Cuban tropical conditions.
