Application of nematodes romanomermis iyengari in breeding sites of anopheles pseudopunctipennis in endemics communities of malaria in oaxaca, mexico.

摘要

We evaluate the application of parasitic nematodes R. iyengari in three endemic communities of malaria in Oaxaca, Mexico. Previously maps of the communities were made with all the breeding sites of mosquito larvae, the Density pre-treatment of mosquito larvae (density of mosquito larvae before the treatments) were determined. The applications were made in all the breeding sites, which varied between 80-8240 m2. Three days later the data of Percentage of Parasitism and Intensity of infection were taken. Seven days after the applications data were taken from Density post-treatment of mosquito larvae. The application rate of 2000 to 3000 nematodes m2 was used. Parasitism of mosquito larvae ranged from 71-100%, and the population reduction of the mosquito larvae varied from 79-88%. In 60% of breeding sites R. iyengari was able to recycle and persisted in the breeding sites, so the application of nematodes controlled the populations of larval An. pseudopunctipennis.
