Abstract

A study to evaluate the effect of R. iyengari, a parasitic nematode, as a biological agent of vector control toward mosquito larvae in the sandpool, an ideal breeding places for malaria and filariasis vectors, was conducted in East Flores. The aim of the present study was to determine: (1). The adaptability and recycling ability of post parasites stage of the nematode in the sandpool. (2). The ability of preparasites (infective stage) to parasitize Cx. quinquefasciatus (laboratory larvae) in centinel cage and An. barbirostris (natural larvae/sandpool). The distribution of R. iyengari post parasites at a dosage of 500 nematodeslm2 revealed that the nematodes mature to adults, mated and layed eggs (adapted), however recycling could not be observed yet. The infection rate of Cx. quinquefasciatus sentinel cages after release through dissections was observed in 70.55%, 48.68% and 3.64% respectively after 1 month, 2 months and 3 months. The mean monthly infection level for An. barbirostris was 28.24%, 16.66% and 31.25% for 1 month, 2 months and 3 months post release dissections respectively.
