Field studies of Culex mosquitoes in Tanzania and Kenya: A systematic review motivated by changing Rift Valley fever virus transmission patterns

open access: yesMedical and Veterinary Entomology, EarlyView.
There were 275 studies reporting Culex abundance, 17 of which explicitly stated the motivation for the study was RVFV. Despite most studies being motivated by other topics, there was good coverage of studies reporting mosquito sampling in areas associated with the risk of RVFV outbreaks. Studies were c.

Transcriptomic meta-signatures identified in Anopheles gambiae populations reveal previously undetected insecticide resistance mechanisms

open access: yesNature Communications, 2018
Increasing insecticide resistance in malaria-transmitting vectors represents a public health threat, but underlying mechanisms are poorly understood. Here, a data integration approach is used to analyse transcriptomic data from comparisons of insecticide

Comparative attraction of Anopheles quadriannulatus and Anopheles arabiensis to humans estimated by comparing their relative abundance in samples of mosquito larvae and adults collected across an ecologically heterogeneous landscape in southern Tanzania Utafiti wa kulinganisha mvuto wa mbu aina ya Anopheles arabiensis na Anopheles quadriannulatus kwa binadamu katika mandhari yenye mazingira mbalimbali kusini mwa Tanzania

open access: yesMedical and Veterinary Entomology, EarlyView.
Light and barrier traps near human activity selectively captured more Anopheles arabiensis, indicating a strong attraction to humans and explicit bias in adult sampling methods. Traps placed in open glades away from humans captured species proportions similar to larval samples, suggesting reduced sampling bias in those settings. Visits by entomological

Cas9-Mediated Gene-Editing in the Malaria Mosquito Anopheles stephensi by ReMOT Control

open access: yesG3: Genes, Genomes, Genetics, 2019
Innovative tools are essential for advancing malaria control and depend on an understanding of molecular mechanisms governing transmission of malaria parasites by Anopheles mosquitoes.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 2 - Immature stages research at a rice irrigation system location in South-Eastern Brazil

open access: yesRevista de Saúde Pública
A relation between a rice irrigation system and mosquito breeding was established in a study undertaken at the Ribeira Valley Experimental Station, from January through December 1992.

Extended time to maturity in Anopheles coluzzii: Implications of late egg hatch for vector control and transgene fitness

open access: yesMedical and Veterinary Entomology, EarlyView.
The fitness of Anopheles coluzzii mosquito lines (VK strain) selected for early and late egg hatching was compared with each other and a reference strain (Mopti). There was an observed increase in fitness in fecundity and survival among the late‐hatching lines, but no negative effects of selection on fecundity and adult survival were detected.

Distribution of Anopheles vectors and potential malaria transmission stability in Europe and the Mediterranean area under future climate change

open access: yesParasites & Vectors, 2019
In the scope of climate change the possible recurrence and/or expansion of vector-borne diseases poses a major concern. The occurrence of vector competent Anopheles species as well as favorable climatic conditions may lead to the re-emergence of ...

Plasticity in malaria parasite development: mosquito resources influence vector-to-host transmission potential

open access: yesFrontiers in Malaria
Parasites rely on exploiting resources from their hosts and vectors for survival and transmission. This includes nutritional resources, which vary in availability between different hosts and changes during infections.

Whole genome shotgun phylogenomics resolve the diving beetle tree of life

open access: yesSystematic Entomology, EarlyView.
A new and strongly supported phylogeny of diving beetles (Dytiscidae) is presented using the largest genomic dataset to date. Laccophilinae and Coptotominae + Lancetinae are early diverging lineages excluded from a large monophyletic clade comprising the remaining eight subfamilies. We identify seven remaining problems in the backbone of the phylogeny,
