Malaria control activities in Iran and novel evaluation of pyriproxyfen as an insect growth regulator (IGR) against malaria vectors in a malarious area

Abstract

There are several measure for vector control including indoor residual spraying, using long lasting impregnated bednet and larvciding for malaria control in Iran. For the first time in the country, the pyriproxyfen 0.5 granule were evaluated in the laboratory (aquarium test), in southeastern Iran. The experiments was carried out in a malarious areas in Sistan and Baluchistan province, southern Iran during malaria transmission season in 2014. Laboratory tests of pyriproxyfen 0.5G at 3 and 5 g/m3 showed 5.5 months residual effect with 98.3-99.6% of inhibition of emergence (IE) compared to 77.5% as survival rate (SR) in untreated group. The findings revealed the promising horizons of pyriproxyfen application as larvicides against malaria vectors at south and southeastern Iran. It is strongly recommended special attention for use of this IGR at an integrated vector control program in the country.
