[Mass breeding of Romanomermis culicivorax (Nematoda: Mermithidae) in the tropical conditions of Cuba].

To develop the process of mass production on a large scale of the parasite nematode Romanomermis culicivorax Ross and Smith, 1976, under the control tropical conditions of Cuba, it was taken into consideration the standardization of a certain number of variables, such as: utilization of eggs in the process of infectation, dosage, types of water, types of substrate, temperature, culture methods, and storage methods of culture batches. High performances in nematoda and approximately the same amount of females and males were obtained when mosquito larvae of the species Culex quinquefasciatus Say, 1823, were exposed to parasite's infective larvae.
