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 disease prevention but the use of the same chemicals for more than 40 years, together with the dissemination of mosquitoes by trade and environmental changes, resulted in the global spread of insecticide resistance. In this context, innovative tools and strategies for vector control, including the management of resistance, are urgently needed. This report summarizes the main outputs of the first international workshop on Insecticide resistance in vectors of arboviruses held in Rio de Janeiro, Brazil, 5–8 December 2016. The primary aims of this workshop were to identify strategies for the development and implementation of standardized insecticide resistance management, also to allow comparisons across nations and across time, and to define research priorities for control of vectors of arboviruses. The workshop brought together 163 participants from 28 nationalities and was accessible, live, through the web (> 70,000 web-accesses over 3 days).

Phenotypic and genotypic pyrethroid resistance ofAedes albopictus, with focus on the 2017 chikungunya outbreak in Italy

“…The need to monitor and better understand phenotypic PR as well as its genetic basis in Ae. albopictus has been recognized by WHO as well as by the recently established Worldwide Insecticide Resistance Network . Indeed, it is likely that PR is more widespread than presently revealed by the few pyrethroid‐resistant Ae.…”

Diterpenes and their derivatives as promising agents against dengue virus and dengue vectors: A literature‐based review

“…Aedes mosquitoes usually bite during daytime, therefore, its contact can be avoided or minimized in various ways, such as the use of mosquito repellents (e.g., non‐sticky creams, coils, aerosols, solids (sticks), pump sprays, liquids), nets (e.g., insecticide treated nets) and wearing, appropriate management of stored water and wastes, destroy the larvae or mature Aedes mosquitoes through chemical treatment (e.g., N,N‐diethyl‐3‐methylbenzamide, diethyl phthalate, diethyl carbate, metofluthrin, oil of lemon‐eucalyptus, picaridin, ethyl hexanediol) (https://www.mosquito.org/page/repellents; Jahan, ). However, repetitive usage of chemicals to manage DENV may develop vector resistance (Corbel et al, ). Accordingly, there is an urgent need to search for alternative therapeutic tools along with the methods for the control of DENV vectors.…”

Autodissemination of Pyriproxyfen as Novel Strategy to Control Dengue Outbreaks: A Review

“…They found a significant cross-contaminate between males and females who are suitable to release the ADAM in the areas with a low density of Aedes populations. Although the density of adult mosquito was declined after four weeks of treatment, further study on the mosquito behavior, study area with a different ecological context, as well as the size of the field trials is needed to validate the efficacy of ADAM in the vector control program [62].…”
