rapid discrimination between anopheles gambiae s.s. and anopheles arabiensis by high-resolution melt (hrm) analysis.	there is a need for more cost-effective options to more accurately discriminate among members of the anopheles gambiae complex, particularly an. gambiae and anopheles arabiensis. these species are morphologically indistinguishable in the adult stage, have overlapping distributions, but are behaviorally and ecologically different, yet both are efficient vectors of malaria in equatorial africa. the method described here, high-resolution melt (hrm) analysis, takes advantage of minute differences in ...	23543777
the combination of npk fertilizer and deltamethrin insecticide favors the proliferation of pyrethroid-resistant anopheles gambiae (diptera: culicidae).	in this laboratory study, we investigated how the biological cycle of anopheles gambiae s.s. (vkpr strain) would be like when grew in an environment containing more or less plant matter (2.5 or 5 g/l) and fertilizer (8-12-8 or 17-23-17 mg/l). half of the environments studied were not exposed to insecticide (control) whereas the other half was submitted to deltamethrin treatment at the concentration of 0.015 mg/l. the bioassays showed that 2.5 g/l of plant matter in water are not sufficient to fe ...	22550627
species composition and temporal distribution of mosquito populations in ibadan, southwestern nigeria.	nigeria has a high burden of vector borne diseases such as malaria and lymphatic filariasis (lf). this study aimed to determine the species composition of mosquitoes in ibadan, southwest nigeria as well as determine their role in malaria and lf transmission. adult mosquitoes were collected by pyrethrum spray catch (psc) and identified and graded according to their abdominal conditions. the mosquitoes were dissected to determine the parity status and to check for microfilariae of wuchereria bancr ...	25520960
insecticide exposure impacts vector-parasite interactions in insecticide-resistant malaria vectors.	currently, there is a strong trend towards increasing insecticide-based vector control coverage in malaria endemic countries. the ecological consequence of insecticide applications has been mainly studied regarding the selection of resistance mechanisms; however, little is known about their impact on vector competence in mosquitoes responsible for malaria transmission. as they have limited toxicity to mosquitoes owing to the selection of resistance mechanisms, insecticides may also interact with ...	24850924
comparative susceptibility to permethrin of two anopheles gambiae s.l. populations from southern benin, regarding mosquito sex, physiological status, and mosquito age.	to investigate what kind of mosquito sample is necessary for the determination of insecticide susceptibility in malaria vectors.	25182557
single-nucleotide polymorphisms for high-throughput genotyping of anopheles arabiensis in east and southern africa.	anopheles arabiensis patton is one of the principal vectors of malaria in sub-saharan africa, occupying a wide variety of ecological zones. this species is increasingly responsible for malaria transmission in africa and is becoming the dominant vector species in some localities. despite its growing importance, little is known about genetic polymorphisms in this species. multiple sequences of various gene fragments from an. arabiensis isolates from cameroon were obtained from genbank. in total, 2 ...	22493848
effect of swamp cultivation on distribution of anopheline larval habitats in western kenya.	malaria resurgence in highland regions of east africa has been on increase. the spatio-temporal distribution of larval habitats of malaria vectors determines the distribution of adult vectors, hence, disease transmission. vector's ecology is necessary for strategic vector control through effective plan for source reduction. mapping of the larval habitats is necessary for targeted control measures. the purpose of this study is to assess and compare the spatial and seasonal variations in anophelin ...	22898476
monitoring malaria vector control interventions: effectiveness of five different adult mosquito sampling methods.	long-term success of ongoing malaria control efforts based on mosquito bed nets (long-lasting insecticidal net) and indoor residual spraying is dependent on continuous monitoring of mosquito vectors, and thus on effective mosquito sampling tools. the objective of our study was to identify the most efficient mosquito sampling tool(s) for routine vector surveillance for malaria and lymphatic filariasis transmission in coastal kenya. we evaluated relative efficacy of five collection methods--light ...	24180120
climate influences on the cost-effectiveness of vector-based interventions against malaria in elimination scenarios.	despite the dependence of mosquito population dynamics on environmental conditions, the associated impact of climate and climate change on present and future malaria remains an area of ongoing debate and uncertainty. here, we develop a novel integration of mosquito, transmission and economic modelling to assess whether the cost-effectiveness of indoor residual spraying (irs) and long-lasting insecticidal nets (llins) against plasmodium falciparum transmission by anopheles gambiae s.s. mosquitoes ...	25688017
