Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

open access: yesInsect 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 ...

An All‐in‐One Metabarcoding Approach to Mosquito and Arbovirus Xenosurveillance

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT Next‐generation sequencing (NGS) has the potential to transform mosquito‐borne disease surveillance but remains under‐utilised. This study introduces a comprehensive multi‐loci metabarcoding‐based MX (molecular xenomonitoring) approach to mosquito and arbovirus surveillance, enabling parallel identification of mosquito vectors, circulating ...

The wMel strain of Wolbachia Reduces Transmission of Zika virus by Aedes aegypti

open access: yesScientific Reports, 2016
Zika virus (ZIKV) is causing an explosive outbreak of febrile disease in the Americas. There are no effective antiviral therapies or licensed vaccines for this virus and mosquito control strategies have not been adequate to contain the virus. A promising

Microhaplotype Methods Enable Relationship Inference in a Bottlenecked Mammalian Species

open access: yesAnimal Conservation, EarlyView.
Northern elephant seals (Mirounga angustirostris) are among the most genetically depauperate mammals in the world. A near‐total population bottleneck in the 19th century, coupled with the breeding system of extreme polygyny, has challenged efforts to estimate individual reproductive success with genetic methods.
