[An oviposition study of the nematode parasitic on Culicidae Romanomermis iyengari in the laboratory].
Laboratory studies allowed determine that female Romanomermis iyengari Welch, 1964, had a reproductive potential of 1975, 29 eggs in an average time of 21,76 days in distilled water with pH of 4.5 and a temperature of 25 +/- 2 degrees C. It was found that females of this nematode began oviposition in an average time of 14.65 days from the moment of emersion of postparasites of the host larvae. In studying the embryonic development, it was observed that the time elapsed from oviposition to egg hatching and the emersion of preparasites was 290,74 hours. It was determined that the optimum time to begin the exploitation of cultures and obtain a greater yield of preparasites under laboratory conditions is the sixth week of storage.
