Deltamethrin resistance in Aedes aegypti results in treatment failure in Merida, Mexico

Abstract The operational impact of deltamethrin resistance on the efficacy of indoor insecticide applications to control Aedes aegypti was evaluated in Merida, Mexico. A randomized controlled trial quantified the efficacy of indoor residual spraying (IRS) against adult Ae. aegypti in houses treated with either deltamethrin (to which local Ae. aegypti expressed a high degree of […]

Eliminate Yellow fever Epidemics (EYE): a global strategy, 2017–2026

Yellow fever (YF) is an acute viral disease of humans and other primates, transmit ted by Aedes species and other mosquito species, and endemic in tropical areas of Africa and Central and South America. YF is preventable by vaccination, a single dose of vaccine being sufficient to induce sustained life-long protective immunity. Vaccination has been […]

International workshop on insecticide resistance in vectors of arboviruses, December 2016, Rio de Janeiro, Brazil

Abstract Vector-borne diseases transmitted by insect vectors such as mosquitoes occur in over 100 countries and affect almost half of the world’s population. Dengue is currently the most prevalent arboviral disease but chikungunya, Zika and yellow fever show increasing prevalence and severity. Vector control, mainly by the use of insecticides, play a key role in […]

Developme ntal M easures: The Z ika Virus, Microceph aly, and H istories of Glob al Northern State Anxieties

ABSTRACT This project seeks to understand anxious and fearful responses to the Zika virus and microcephaly that began circulating widely in February, 2016. My project works to uncover racial histories embedded in the contemporary scientific and medical practice of measuring head circumference. By arguing that microcephaly is a racialized metric of civilizational and human development, […]

Assessment of the Probability of Autochthonous Transmission of Chikungunya Virus in Canada under Recent and Projected Climate Change

Background:Chikungunya virus (CHIKV) is a reemerging pathogen transmitted by Aedes aegypti and Aedes albopictus mosquitoes. The ongoing Caribbean outbreak is of concern due to the potential for infected travelers to spread the virus to countries where vectors are present and the population is susceptible. Although there has been no autochthonous transmission of CHIKV in Canada, […]

Design and construction of a trap for the surveillance of Aedes ( Stegomyia ) aegypti (Diptera: Culicidae)

Introduction: Understanding Aedes (Stegomyia) aegypti (L) behavior will provide insight into the design of entomological surveillance devices. Objective: Design and build a trap for surveillance Aedes aegypti. Methodology: We examined egg-laying preference and the ability to capture adult Ae. aegypti using containers that differed in shape, color and internal retention systems. The characteristics most effective […]

Three months of Aedes aegypti control with a novel infusion bag formulation of Chilodonella uncinata in domestic water – storage container in Delhi

Abstract The efficacy of Chilodonella uncinata formulation, a naturally occurring protozoan biolarvicide, was evaluated in 40 liter domestic water-storage tub, one of the most common and preferred larval habitat of the dengue vector Aedes aegypti, in NCT Delhi. The formulation used contained base material as sterilized sand to entrap (3.5×10 4 cells/ml) of th e […]

Zika virus evolution and spread in the Americas

Although the recent Zika virus (ZIKV) epidemic in the Americas and its link to birth defects have attracted a great deal of attention1, 2, much remains unknown about ZIKV disease epidemiology and ZIKV evolution, in part owing to a lack of genomic data. Here we address this gap in knowledge by using multiple sequencing approaches […]
