Quantification of sporozoite expelling by Anopheles mosquitoes infected with laboratory and naturally circulating P. falciparum gametocytes

eLife
It is currently unknown whether all Plasmodium falciparum-infected mosquitoes are equally infectious. We assessed sporogonic development using cultured gametocytes in the Netherlands and naturally circulating strains in Burkina Faso.

Seasonal and spatial dynamics of the primary vector of plasmodium knowlesi within a major transmission focus in Sabah, Malaysia [PDF]

, 2015
Background The simian malaria parasite Plasmodium knowlesi is emerging as a public health problem in Southeast Asia, particularly in Malaysian Borneo where it now accounts for the greatest burden of malaria cases and deaths.

Full‐length coding sequence analysis of the voltage‐gated sodium channel and acetylcholinesterase genes reveals target‐site mutations and acetylcholinesterase gene duplication in housefly (Musca domestica) populations in Japanese livestock barns

Medical and Veterinary Entomology, EarlyView.
We simultaneously analysed insecticide resistance mutations in VGSC and AChE using NGS and hybridization probe capture in houseflies collected from livestock facilities for the first time. Resistance mutations in both VGSC and AChE were detected in most wild populations, suggesting widespread distribution of resistance genes.

An experimental hut evaluation of PermaNet(®) 3.0, a deltamethrin-piperonyl butoxide combination net, against pyrethroid-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes in southern Benin.

, 2010
PermaNet 3.0 is a long-lasting combination net with deltamethrin present on the sides and a mixture of deltamethrin and piperonyl butoxide (PBO), an oxidase synergist, on the top panel.

The genetic basis of host preference and resting behavior in the major African malaria vector, Anopheles arabiensis [PDF]

, 2016
Malaria transmission is dependent on the propensity of Anopheles mosquitoes to bite humans (anthropophily) instead of other dead end hosts. Recent increases in the usage of Long Lasting Insecticide Treated Nets (LLINs) in Africa have been associated ...

Comparative efficacy and studies of mode of action of minerals from diatoms against three species of filth flies

Medical and Veterinary Entomology, EarlyView.
Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...

Climate Change and Highland Malaria: Fresh Air for a Hot Debate [PDF]

, 2010
In recent decades, malaria has become established in zones at the margin of its previous distribution, especially in the highlands of East Africa.

A multiplex assay to detect mosquito species, bloodmeal host source and Plasmodium in malaria vectors using Nanopore amplicon sequencing

Medical and Veterinary Entomology, EarlyView.
Insectary‐reared mosquitoes were simultaneously assessed for species identification, bloodmeal source analysis and Plasmodium detection, using a single multiplexed sequencing run on the MinION sequencing platform. The method was applied to 150 insectary‐reared mosquitoes, representing nine species blood‐fed with five vertebrate hosts and 40 samples for

Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

Medical and Veterinary Entomology, EarlyView.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...

Reduced bio-efficacy of aged PermaNet® 3.0 Nets against local pyrethroid-resistant Anopheles arabiensis in Western Kenya

Frontiers in Tropical Diseases
BackgroundLong-lasting insecticidal nets (LLINs) are central to malaria control and designed to protect for up to three years; however, increasing pyrethroid resistance undermines their effectiveness.
