In a large malaria endemic area in Panaji city, Goa, India, the weekly application of the biolarvicide Bacillus sphaericus (Strain 101, Serotype H 5a 5b) at the rate of 1 g/m2 in the main Anopheles stephensi larval habitats, viz., curing waters, masonry tanks, and sump tanks (under construction), from April to December 1993 resulted in a sharp decline in the habitat positivity (range 0.13-8.0%)...

Bacillus spp. based larvicides are increasingly replacing, with numerous advantages, chemical insecticides in programmes for controlling black fly and mosquito populations. Brazil was among the pioneers in adopting Bacillus thuringiensis israelensis (B.t.i) to control black flies. However, the major current mosquito control programme in Brazil, the Programme for Eradication of Aedes aegypti lau...

or solid particles with a size in the range of 10–1000 nm. Depending upon the method of preparation, nanoparticles, nanospheres or nanocapsules can be obtained. Controlled release and particle degradation characteristics can readily be modulated by the choice of matrix constituents1. Efficacy of Chrysosporium tropicum, a pathogenic fungus mediated silver and gold nanoparticles was reported agai...

Two stable infections of Wolbachia pipientis, wMelPop and wMel, now established in Aedes aegypti, are being used in a biocontrol program to suppress the transmission of dengue. Any effects of Wolbachia infection on insecticide resistance of mosquitoes may undermine the success of this program. Bioassays of Ae. aegypti were conducted to test for differences in response to insecticides between Wo...

The application of larvicide from botanical origin was extensively studied as an essential part mosquito prevention. This study aimed to assess the difference in container index (CI) based on characteristics water containers using <em>Ziziphus mauritiana</em> leaf extract solution. A quasi- experiment research done among 300 selected with temephos a control and 9% solution treatment...
