Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

Journal of Applied Entomology, EarlyView.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

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.

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 ...

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

The serpin gene family in Anopheles gambiae [PDF]

Gene, 2009
Serpins (serine protease inhibitors) regulate some innate immune responses of insects by inhibiting endogenous proteases. In this study, we characterized the serpin (SRPN) gene family in the mosquito Anopheles gambiae, the major malaria vector in Sub-Saharan Africa. We identified 18 A. gambiae SRPN genes, all on chromosomes 2 and 3, through searches of

Potential distribution of dominant malaria vector species in tropical region under climate change scenarios.

PLoS ONE, 2019
Risk assessment regarding the distribution of malaria vectors and environmental variables underpinning their distribution under changing climates is crucial towards malaria control and eradication. On this basis, we used Maximum Entropy (MaxEnt) Model to

Indoor residual spraying of distinct insecticide formulations in a household‐scale micro‐mosaic format: Feasibility and effectiveness for malaria vector control in rural Zambia

Medical and Veterinary Entomology, EarlyView.
Densities of all Anopheles species were approximately comparable across all IRS regimes. No differences observed between treatment regimes regarding species composition of the Anopheles funestus group or An. gambiae complex. This operational pilot demonstrates the practical feasibility of IRS micro‐mosaics, despite the inherent increase in deployment ...

Dramatic decreases of malaria transmission intensities in Ifakara, south-eastern Tanzania since early 2000s

Malaria Journal, 2018
Background Ongoing epidemiological transitions across Africa are particularly evident in fast-growing towns, such as Ifakara in the Kilombero valley, south-eastern Tanzania.

Effect of blood meals and mating on biodemographic characteristics of Aedes albopictus

Physiological Entomology, EarlyView.
Lifespan did not differ between virgin and mated males and females. The number of blood meals (one and two) significantly reduced adult lifespan compared with those with no blood meal. The effect of the second blood meal doubled females' egg production and their reproductive output.
