Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

Insect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

Vector control for the chikungunya disease: chemical control versus biological control: a mathematical point of view. [PDF]

, 2010
The aim of this talk is to present recent investigations on the Chikungunya Disease that hitted Réunion Island, a French territory in Indian Ocean, in 2005 and 2006. Chikungunya is a vectorborne Disease, usually localized in Asia and East-Africa. In 2005,

A Metapopulation Model for Chikungunya Including Populations Mobility on a Large-Scale Network

, 2012
In this work we study the influence of populations mobility on the spread of a vector-borne disease. We focus on the chikungunya epidemic event that occurred in 2005-2006 on the R\'eunion Island, Indian Ocean, France, and validate our models with real ...

New adhesive traps to monitor urban mosquitoes with a case study to assess the efficacy of insecticide control strategies in temperate areas [PDF]

, 2015
Background: Urban mosquitoes in temperate regions may represent a high nuisance and are associated with the risk of arbovirus transmission. Common practices to reduce this burden, at least in Italian highly infested urban areas, imply calendar-based ...

The Ecological Factors Associated With the Survival, Establishment, and Movement of Aedes aegypti and Ae. albopictus: A Scoping Review

Journal of Applied Entomology, EarlyView.
ABSTRACT Aedes aegypti and Ae. albopictus are mosquito species of public health significance and collectively responsible for the transmission of several arboviruses. Ongoing climatic changes are anticipated to have impacts on their survival, establishment, and movement.

Wolbachia versus dengue: Evolutionary forecasts. [PDF]

, 2013
A novel form of biological control is being applied to the dengue virus. The agent is the maternally transmitted bacterium Wolbachia, naturally absent from the main dengue vector, the mosquito Aedes aegypti.

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 ...

Spotted fever group Rickettsia in Haemaphysalis ticks: genetic diversity and first detection of “Candidatus Rickettsia jingxinensis” in India

Ticks and Tick-Borne Diseases
Ticks are important vectors of rickettsial pathogens, particularly in regions where livestock, wildlife, and humans overlap. Despite increasing reports of rickettsioses in India, molecular evidence of Rickettsia species in questing ticks from the Western
