BACKGROUND Control and prevention of dengue relies heavily on the application of insecticides to control dengue vector mosquitoes. In Colombia, application of the larvicide temephos to the aquatic breeding sites of Aedes aegypti is a key part of the dengue control strategy. Resistance to temephos was recently detected in the dengue-endemic city of Cucuta, leading to questions about its efficacy...

Pyriproxyfen is an insect growth regulator that affects the physiology of morphogenesis, reproduction and embryogenesis of insects. It exhibits a high level of activity against mosquito larvae inhibiting adult emergence at very low dose rates. It has low mammalian toxicity and environmental impact. This paper reviews pyriproxyfen efficacy against nuisance mosquitoes and vectors of dengue and ma...

The objective of the Onchocerciasis Control Progininme (OCP) is to eliminate onchocerciasis as a disease of public îinportance and as an obstacle to socio-economic development. The OCP was initially based solely OIT the control of the blaclcfly vector, Simulium damnosum sensu lato, by insecticide spraying of the breeding sites on river systems, where larval stages develop. Results of monitoring...

BACKGROUND The control of Aedes albopictus, a major vector for viral diseases, such as dengue fever and chikungunya, has been largely reliant on the use of the larvicide temephos for many decades. This insecticide remains a primary control tool for several countries and it is a potential reliable reserve, for emergency epidemics or new invasion cases, in regions such as Europe which have banned...

Insects of the Simuliidae family have been the object of control in Rio Grande do Sul since the 70s. Their constant attacks became a social-economical problem as well as a problem of Public Health, with serious consequences to men and to the economy of the areas in which the insects develop. At first, the control was done with a chemical larvicide Themephos ABATE 500 E, but an imperfect measuri...

<em>Ocimum sanctum</em> Linn, known as holy basil, is a larvicide, which relatively safe compared to synthetic insecticides. This study investigates the larvicidal activity of granule formulation Indonesian basil leaf extract against third larval instar <em>Aedes aegypti</em>. The leaves was obtained by maceration process with 96% ethanol. formulated various concentratio...

A model with six mutually-exclusive compartments related to Dengue disease is presented. In this model there are three vector control tools: insecticides (larvicide and adulticide) and mechanical control. The problem is studied using an Optimal Control (OC) approach. The human data for the model is based on the Cape Verde Dengue outbreak. Some control measures are simulated and their consequenc...

background: malaria is still a health problem in iran. there are several vector control activities, including indoor residual spraying, using insecticide treated nets and larviciding including temephos. in addition nuisance mosquitos are prevalent in the urban areas. so that evaluation of this species to larvicide will provide a clue for management of vector control activities. methods : two mo...
