Background Culex quinquefasciatus (Diptera: Culicidae) is an important vector for many human diseases. The aim of this study was to evaluate the susceptibility level of larval and adult stages of Cu. quinquefasciatus to different groups of WHO recommended insecticides for vector control. Methods Larval stages of the Culex mosquitoes were collected from their natural habitats in Rafsanjan Coun...

Several active substances, belonging to the pyrethroid family, are used in fight against mosquitoes. The use of pesticides is not without consequences for health and environment. species mosquitoes (Anopheles Culex) increasingly developing resistance these which makes insecticides very little or at all effective. present study aims evaluate effectiveness most commonly city Niamey order produce ...

Synopsis We report mosquito behaviors for removing accumulated drops of water which would otherwise increase the energy expended during takeoff and free flight. These techniques take advantage of the insect’s small size and great structural strength. To dry their wings before takeoff, mosquitoes employ a flutter stroke, at double the wingbeat frequency of normal flight, generating nearly 2500 g...

Insecticides are one of the major tools for controlling vector populations and for reducing the transmission of human pathogens. However, there are few new insecticides being developed and marketed for vector control. Herein, we report on the toxicity of six novel insecticides to both adult and larval Aedes aegypti (L). and the toxicity of three novel insect growth regulators (IGRs) to larvae. ...

Mosquitoes (Diptera: Culicidae) are the most medically important arthropods worldwide, vectoring numerous agents that negatively affect humans, including dengue, arboviral encephalitides and malaria parasites. These mosquito-borne pathogens adversely affect millions of people annually, and the total burden of diseases associated with mosquitoes is well documented (e.g. see Sachs and Malaney 200...

Background: The German cockroach (Blatella germanica) is one of the most important vectors of public health interest due to its involvement in the transmission of infectious diseases. Different insecticides are used to control cockroaches; however, resistance developed against most of insecticides has made them ineffective. Attempts should always be made to find proper alternat...

BACKGROUND Malaria control through use of long-lasting insecticidal nets (LN) is threatened by the selection of anopheline mosquitoes strongly resistant to pyrethroid insecticides. To sustain future effectiveness it is essential to identify and evaluate novel insecticides suitable for nets. Mixtures of two insecticides with contrasting mode of action have the potential to kill resistant vectors...

Insecticide-treated nets and indoor residual spray programs for malaria control are entirely dependent on pyrethroid insecticides. The ubiquitous exposure of Anopheles mosquitoes to this chemistry has selected for resistance in a number of populations. This threatens the sustainability of our most effective interventions but no operationally practicable way of resolving the problem currently ex...
