The Spatial Spread and the Persistence of Gene Drives Are Affected by Demographic Feedbacks, Density Dependence and Allee Effects

Molecular Ecology, EarlyView.
ABSTRACT Homing gene drive alleles bias their own transmission by converting wild‐type alleles into drive alleles. If introduced in a natural population, they might fix within a relatively small number of generations, even if they are deleterious.

CRISPR/Cas9 -mediated gene knockout of Anopheles gambiae FREP1 suppresses malaria parasite infection

PLoS Pathogens, 2018
Plasmodium relies on numerous agonists during its journey through the mosquito vector, and these agonists represent potent targets for transmission-blocking by either inhibiting or interfering with them pre- or post-transcriptionally.

Impact of sugarcane irrigation on malaria vector Anopheles mosquito fauna, abundance and seasonality in Arjo-Didessa, Ethiopia

Malaria Journal, 2020
Despite extensive irrigation development in Ethiopia, limited studies assessed the impact of irrigation on malaria vector mosquito composition, abundance and seasonality.

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 ...

Anopheles arabiensis and Anopheles funestus biting patterns in Dielmo, an area of low level exposure to malaria vectors

Malaria Journal, 2020
In Dielmo, Senegal, the widespread use of long-lasting insecticidal nets has decreased both the incidence of malaria and the density of the Anopheles population.

Host‐feeding preferences of Culex pipiens and its potential significance for flavivirus transmission in the Camargue, France

Medical and Veterinary Entomology, EarlyView.
We identified Culex pipiens bloodmeals at the species level in natural, agricultural and peri‐urban habitats and calculated host preferences based on forage ratios. This analysis showed Passeriformes, and in particular Columba livia, Passer montanus and Turdus sp., to be the preferred Cx. pipiens hosts.

The genetic architecture of target‐site resistance to pyrethroid insecticides in the African malaria vectors Anopheles gambiae and Anopheles coluzzii

bioRxiv, 2018
Resistance to pyrethroid insecticides is a major concern for malaria vector control, because these are the compounds used in almost all insecticide-treated bed-nets (ITNs), and are also widely used for indoor residual spraying (IRS).

Comportamento epidemiológico da malária nos municípios que compõem a Bacia do Alto Paraguai, Mato Grosso do Sul, no período de 1990 a 1996

Cadernos de Saúde Pública
Com base em dados secundários levantados na Coordenação Regional da Fundação Nacional de Saúde/Ministério da Saúde (FNS/MS), obteve-se o número de casos de malária registrados na Bacia do Alto Paraguai (BAP), no Mato Grosso do Sul (MS): 159, 126, 135, 61,

Morin hydrate reduces survival and fertility, delays development and weakens lipid reserves in Aedes aegypti

Medical and Veterinary Entomology, EarlyView.
Morin hydrate promoted mortality and reduced the rate of pupation and egg laying in Aedes aegypti larvae that survive treatment. Morin hydrate reduces the levels of triacylglycerol, the main lipid reserve in A. aegypti larvae. The expression of proteins involved in lipogenesis and lipolysis was downregulated and upregulated, respectively, in larvae ...

Impact of vector control interventions on malaria transmission intensity, outdoor vector biting rates and Anopheles mosquito species composition in Tororo, Uganda

Malaria Journal, 2019
Long-lasting insecticidal nets (LLINs) and indoor residual spraying of insecticide (IRS) are widely recommended for the prevention of malaria in endemic regions.
