during 1981-83, propoxure residual spraying operations were discontinued and only extensive larviciding, using a mixture of fuel oil, gasoil or abate larvicide, on a ten days interval basis, and sanitary improvements wetre used in different areas of the city for the control of mosquito breeding places. the results of the indoor adult mosquitoes and larval densities indicated that in the years 1...

BACKGROUND Vector and malaria parasite's rising resistance against pyrethroid-impregnated bed nets and antimalarial drugs highlight the need for additional control measures. Larviciding against malaria vectors is experiencing a renaissance with the availability of environmentally friendly and target species-specific larvicides. In this study, we analyse the perception and acceptability of spray...

Because it is often logistically impossible to monitor all catch basins within an operational area, local mosquito control programs will preemptively treat catch basins with larvicides each season. However, these larvicides can, ostensibly, be considered water quality pollutants. To experimentally reduce the use of larvicides toward improving water quality, 30 basins within a small 0.7-km(2) re...

Expansive chemical-based vector control has resulted in development of vector resistance to different insecticides harnessed for prevention of disease transmission in public health. The environmentally safe insect growth regulators and microbial larvicides provide potential tools for insecticide resistance management. The efficacy and persistence of Dimilin GR-2% and Mosquiron 10 EC insect grow...

Multiple synthetic products are used against mosquitoes to kill them and inhibit the transmission of these vector-borne diseases. The continuous use produces detrimental effects on environment non-target organisms, which also develops resistance in mosquito. In last few decades, there has been a exploration herbal extract-based insecticides. These plants extract essential oils that have emerged...

At the Conference held at Birnagar in February 1929 to discuss the problem of malaria in that town, I submitted a proposal for concentrating attack upon Anopheles philippinensis which was found to carry malarial parasites in Nature in the Nadia District. In preference to a general campaign against anophelines, Sir Malcolm Watson, who presided at the meeting, accepted the view that the breeding ...

Two biological formulations of microbial agents Bacillus thuringiensis and Bacillus sphaericus known by their trade names as Vectobac 12 AS and VectoLex CG (Corn Cob) granules, respectively were obtained from Abbott Laboratories of North Chicago, USA. The B. sphaericus formulation was used in trials against Culex mosquito larvae in choked gutters at Labadi, Ashaiman and Nungua in the Greater Ac...

In most parts of sub-Saharan Africa, malaria is still the most important vector borne disease, severely affecting people ́s lives and causing economic loss. Malaria vector control to date almost exclusively relies on long lasting insecticide treated nets (LLINs) and indoor residual spraying (IRS), while other approaches such as larviciding are less implemented. Rising resistances against commonl...
