The susceptibility of Anopheles mosquitoes to Plasmodium infections relies on complex interactions between the insect vector and the malaria parasite.
Here we report on a small-scale village trial carried out at two localities where malaria vectors were resistant to pyrethroid insecticides. Methods. Nets were distributed to cover all sleeping spaces and evaluated for insecticidal activity.
This study evaluated dose-response, persistence, irritancy and wash resistance of mosquito nets treated with a synergized natural pyrethrins-formulation against Anopheles gambiae s.s.
Very low mortality was observed in the water control. M. anisopliae in Suneem formulation could be developed for a spray technique, before being introduced in vector control.
In contrast to previous laboratory investigation, ICON(R) Maxx-treated nets showed only moderate KD and mortality rates.
The M and S molecular forms of the African malaria vector Anopheles gambiae (Diptera: Culicidae) are morphologically identical incipient species in which reproductive isolation is incomplete, enabling low-level gene flow between forms.
We describe the spatio-temporal dynamics of malaria transmission intensity measured by mosquito density and EIR in the KEMRI/CDC health and demographic surveillance system using entomological data collected during 2002-2004.
Insecticide resistance is an ideal model to study the emergence and spread of adaptative variants.
In the last decade there have been marked reductions in malaria incidence in sub-Saharan Africa.
The results of this study have confirmed that An.gambiae have maintained and developed the resistance to pyrethroids, but are still susceptible to bendiocarb.
