Detection of a new pyrethroid resistance mutation (V410L) in the sodium channel of Aedes aegypti: a potential challenge for mosquito control

Scientific Reports, 2017
The yellow fever mosquito, Aedes aegypti, particularly in Neotropical regions, is the principal vector of dengue, yellow fever, Zika and Chikungunya viruses.

RNAi Regulator C3PO Promotes Arbovirus Infection in Insect Vectors

Advanced Science, EarlyView.
RNA interference (RNAi) is vital for eukaryotes to defend against virus infection. The C3PO complex takes part in RNAi but its role in regulating viral infection remains unclear. This work finds that insect C3PO facilitates arbovirus replication by degrading precursors of miRNAs, especially miR‐971‐3p.

The impact of large-scale deployment of Wolbachia mosquitoes on dengue and other Aedes-borne diseases in Rio de Janeiro and Niterói, Brazil: study protocol for a controlled interrupted time series analysis using routine disease surveillance data [version 2; peer review: 2 approved, 1 approved with reservations]

F1000Research, 2020
Background: Rio de Janeiro and Niterói are neighbouring cities in southeastern Brazil which experience large dengue epidemics every 2 to 5 years, with >100,000 cases notified in epidemic years. Costs of vector control and direct and indirect costs due to

Remote sensing and dynamic modelling to forecast Rift Valley fever outbreaks in Senegal [PDF]

, 2012
Rift Valley Fever (RVF) is a vector-borne viral zoonosis, transmitted either through exposure to infected animals or through bites from infected mosquitoes, mainly from the Aedes or Culex genera.

Spatial and temporal hot spots of Aedes albopictus abundance inside and outside a South European metropolitan area [PDF]

, 2016
Aedes albopictus is a tropical invasive species which in the last decades spread worldwide, also colonizing temperate regions of Europe and US, where it has become a public health concern due to its ability to transmit exotic arboviruses, as well as ...

Mosquito Innate Immunity

Insects, 2018
Mosquitoes live under the endless threat of infections from different kinds of pathogens such as bacteria, parasites, and viruses. The mosquito defends itself by employing both physical and physiological barriers that resist the entry of the pathogen and

Machine Learning‐Assisted Infectious Disease Detection in Low‐Income Areas: Toward Rapid Triage of Dengue and Zika Virus Using Open‐Source Hardware

Advanced Intelligent Discovery, EarlyView.
This study introduces an affordable machine learning platform for simultaneous dengue and zika detection using fluorine‐doped tin oxide thin films modified with gold nanoparticles and DNA aptamers. Designed for low‐cost, hardware‐limited devices (< $25), the model achieves 95.3% accuracy and uses only 9.4 kB of RAM, demonstrating viability for resource‐

Mapping of Aedes albopictus abundance at a local scale in Italy [PDF]

, 2017
Given the growing risk of arbovirus outbreaks in Europe, there is a clear need to better describe the distribution of invasive mosquito species such as Aedes albopictus. Current challenges consist in simulating Ae. albopictus abundance, rather than its

Electronic‐Free Particle Robots Communicate through Architected Tentacles

Advanced Intelligent Systems, EarlyView.
This work introduces a new class of particle robots that communicate without any electronic components. Their communication protocols are encoded in the geometry of their tentacles are and realized solely through physical contact. Building on these simple communication schemes, electronic‐free particle robots can achieve a range of collective ...
