Malaria remains one of the most important causes of morbidity and death in sub-Saharan Africa. Along with early diagnosis and treatment of malaria cases and intermittent preventive treatment in pregnancy (IPTp), vector control is an important tool in the reduction of new cases. Alongside the use of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS), targeting the vector larvae with biological larvicides, such as Bacillus thuringiensis israelensis (Bti) is gaining importance as a means of reducing the number of mosquito larvae before they emerge to their adult stage. This study presents data corroborating the entomological impact of such an intervention in a rural African environment.
While bed nets and insecticide spraying have had significant impact on malaria burden in many endemic regions, outdoor vector feeding and insecticide resistance may ultimately limit their contribution to elimination and control campaigns. Complementary vector control methods such as endectocides or systemic insecticides, where humans or animals are treated with drugs that kill mosquitoes upon ingestion via blood meal, are therefore generating much interest. This work explores the conditions under which long-lasting systemic insecticides would have a substantial impact on transmission and burden.
Gene drive mosquitoes are a novel approach to vector control being developed to help tackle malaria. A gene drive increases the frequency of a desired gene and its phenotypic effect into a mosquito population through reproduction in relatively few generations . Combining gene drive with the precision of gene editing, scientists are able to modify the Anopheles mosquito genome and push modifications through natural vector populations.
Majority of the community members recognized presence of mosquito swarms in their communities but did not associate these swarms with mosquito mating.
Mosquitoes use many cues to assess whether a habitat is conducive for reproduction, possibly including the presence of stimuli from aquatic macrophytes.
This semi-automated qPCR method enables accurate detection of low-level P. falciparum oocyst infections in mosquito midguts, and may improve the sensitivity, specificity and throughput of assays used to evaluate candidate transmission-blocking interventions.
Ivermectin has captured the imagination of a small group of global health scientists as one approach to solving the problem of residual transmission of malaria. This old, so-called wonder drug—an endectocide that targets both endoparasites and ectoparasites—was originally identified as a natural substance by Satoshi Ōmura of Kitasato Institute. The drug was further developed by William Campbell of Merck Labs as a potent anthelmintic, originally for use in veterinary health and targeting more than 20 species of helminth.
Fine-scale differences in endophagy and exophagy, and temporal differences among months and hours exist in biting patterns among mosquito taxa in southern coastal Ecuador.
The proposed bead-beating CSP-ELISA/qPCR methodology considerably increases throughput for the detection of mosquito infection.
The new design houses had fewer mosquitoes and were cooler than modified and unmodified traditional homes.
