BACKGROUND Malaria burden is high in Nigeria, yet information on the major mosquito vectors is lacking especially in the Sudan savannah region of the country. In order to facilitate the design of future insecticide-based control interventions in the region, this study has established the resistance profile of An. gambiae s.l. populations in two northern Nigeria locations and assessed the contri...

The yellow fever mosquito, Aedes aegypti, particularly in Neotropical regions, is the principal vector of dengue, yellow fever, Zika and Chikungunya viruses. Pyrethroids remain one of the most used insecticides to control Aedes mosquitoes, despite the development of pyrethroid resistance in many mosquito populations worldwide. Here, we report a Brazilian strain of A. aegypti with high levels (a...

Susceptibility baselines and diagnostic doses of the technical grade insecticides deltamethrin, permethrin, fenitrothion, and propoxur were established based on Aedes aegypti (L.), Bora (French Polynesia), a reference susceptible strain. Field-collected Aedes mosquitoes from each part of Thailand were subjected to bioassay for their susceptibility to the diagnostic doses of each insecticide. Al...

The current rise in insecticide resistance of mosquitoes to synthetic compounds that used be very effective is great concern malaria control. Several bio-compounds from plants and essential oils have insecticidal or repellent potencies. However, lack harmonization complete research on insecticides plant origin obscured the breakthrough discovering an alternative plant-based mosquito DEET-based ...

INTRODUCTION The need to control dengue transmission by means of insecticides has led to the development of resistance to most of the products used worldwide against mosquitoes. In the State of São Paulo, the Superintendência de Controle de Endemias (SUCEN) has annually monitored the susceptibility of Aedes aegypti to insecticides since 1996; since 1999, surveys were conducted in collaboration ...

Mosquitoes are considered one of the most important threats worldwide due to their ability vector pathogens. They responsible for transmission major pathogens such as malaria, dengue, zika, or chikungunya. Due lack treatments prophylaxis against many transmitted and an increasing prevalence mosquito resistance insecticides drugs available, alternative strategies now being explored. Some these i...

Mosquito borne diseases such as malaria and dengue cause extensive morbidity and mortality and are a major economic burden within disease-endemic countries. Control of both these diseases, which in most countries are primarily transmitted in and around the home, is difficult. Malaria and dengue are effectively managed through a combination of vector control, drugs and management of clinical ill...

Two stable infections of Wolbachia pipientis, wMelPop and wMel, now established in Aedes aegypti, are being used in a biocontrol program to suppress the transmission of dengue. Any effects of Wolbachia infection on insecticide resistance of mosquitoes may undermine the success of this program. Bioassays of Ae. aegypti were conducted to test for differences in response to insecticides between Wo...

The frequent use of systemic insecticides to manage insect pests leads to a destabilisation of ecosystem and enhanced resistance to insecticides and pests suggesting a clear need for alternatives. In addition, increasing documentation of negative environmental and health impact of synthetic insecticides and increasingly stringent environmental regulation of pesticides have resulted in renewed i...
