Microsporidia MB is found predominantly associated with Anopheles gambiae s.s and Anopheles coluzzii in Ghana [PDF]
Scientific Reports, 2021 A vertically transmitted microsporidian, Microsporidia MB, with the ability to disrupt Plasmodium development was reported in Anopheles arabiensis from Kenya, East Africa.

Photoperiodic responses of Sahelian malaria mosquitoes Anopheles coluzzii and An. arabiensis [PDF]
Parasites & Vectors, 2017 Background Throughout large parts of sub-Saharan Africa, seasonal malaria transmission follows mosquito density, approaching zero during the dry season and peaking during the wet season.

Chromosome-level genome assemblies of the malaria vectors Anopheles coluzzii and Anopheles arabiensis [PDF]
GigaScience, 2021 Abstract Background Anopheles coluzzii and Anopheles arabiensis belong to the Anopheles gambiae complex and are among the major malaria vectors in sub-Saharan Africa. However, chromosome-level reference genome assemblies are still lacking for these medically important mosquito species.

Extended time to maturity in Anopheles coluzzii: Implications of late egg hatch for vector control and transgene fitness. [PDF]
Med Vet EntomolThe 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.

Antibiotic Treatment in Anopheles coluzzii Affects Carbon and Nitrogen Metabolism [PDF]
Pathogens, 2020 The mosquito microbiota reduces the vector competence of Anopheles to Plasmodium and affects host fitness; it is therefore considered as a potential target to reduce malaria transmission. While immune induction, secretion of antimicrobials and metabolic competition are three typical mechanisms of microbiota-mediated protection against invasive ...

Genetic variation at the Cyp6m2 putative insecticide resistance locus in Anopheles gambiae and Anopheles coluzzii [PDF]
Malaria Journal, 2021 Abstract Background The emergence of insecticide resistance is a major threat to malaria control programmes in Africa, with many different factors contributing to insecticide resistance in its vectors, Anopheles mosquitoes.

Behavioural analysis of swarming mosquitoes reveals high hearing sensitivity in Anopheles coluzzii [PDF]
Journal of Experimental Biology, 2022 ABSTRACT Mosquitoes of many species mate in station-keeping swarms. Mating chases ensue as soon as a male detects the flight tones of a female with his auditory organs. Previous studies of hearing thresholds have mainly used electrophysiological methods that prevent the mosquito from flying naturally. The main aim of this study was to

Age-dependent regulation of host seeking in Anopheles coluzzii [PDF]
Scientific Reports, 2019 AbstractBehavioural attraction of the malaria vector Anopheles coluzzii to human host odour increases during adult maturation. We have previously demonstrated that the onset of host seeking in An. coluzzii coincides with an increased sensitivity of the CO2-sensitive neurons and abundance of chemosensory receptor gene transcripts in the maxillary palp ...

The origin of island populations of the African malaria mosquito, Anopheles coluzzii [PDF]
Communications Biology, 2021 AbstractAnopheles coluzzii is a major malaria vector throughout its distribution in west-central Africa. Here we present a whole-genome study of 142 specimens from nine countries in continental Africa and three islands in the Gulf of Guinea. This sample set covers a large part of this species’ geographic range.

Mating competitiveness of sterile male Anopheles coluzzii in large cages [PDF]
Malaria Journal, 2014 Understanding the factors that account for male mating competitiveness is critical to the development of the sterile insect technique (SIT). Here, the effects of partial sterilization with 90 Gy of radiation on sexual competitiveness of Anopheles coluzzii allowed to mate in different ratios of sterile to untreated males have been assessed.
