Mosquitoes control

Develop suitable replacements for chlorpyrifos in mosquito control programs. These replacement compounds should exhibit a relatively long half-life in aquatic environments while avoiding the broad-spectrum toxicity typical of chlorpyrifos to large numbers of nontarget organisms. 

Restrict the use of chlorpyrifos for mosquito control in wetlands, estuaries, and waterfowl breeding areas because recommended treatment levels are demonstrably harmful to nontarget resident biota.

Abstract Metofluthrin (commercial name SumiOne, Eminence ) is a novel pyrethroid insecticide developed by Sumitomo Chemical Co., Ltd. Metofluthrin has extremely high insecticidal activity to various pest insects, especially to mosquitoes. In addition, Metofluthrin has relatively high volatility and low mammalian toxicity. Metofluthrin is therefore suitable for use not only in conventional mosquito control formulations such as coils and liquid vaporizers, but also in a variety of novel devices that do not require heating, such as fan vaporizers and paper and resin emanators. Here we describe the insecticidal activity of Metofluthrin mainly against mosquitoes in various formulations in both laboratory and field trials. 

Metofluthrin is a suitable active ingredient for various formulations and devices due to its high lethal/knockdown activity against pest insects (especially mosquitoes), as well as having low mammalian toxicity and favorable physicochemical properties. This report summarizes its outstanding efficacy in various mosquito control formulations in both laboratory tests and field trials [2],... 

Natural vaporization agents, where the active ingredient is formulated on paper or resin, and where it is vaporized without heating or use of power, are easy to use, so there is particular high potential for associated new developments in the field of mosquito control. Insecticides that can be used in formulations for this purpose must possess the characteristics of room temperature vapor action, high level activity, and a high degree of safety for mammals. Metofluthrin meets all of these requirements. 

Metofluthrin is a newly developed highly effective pyrethroid which has excellent insecticidal activity against mosquitoes. Due to its superior characteristics, Metofluthrin is suitable for use in various types of mosquito control formulation, including mosquito coils and liquid vaporizers. Metofluthrin also has excellent... 

Caution Humans are infectious for mosquitoes for at least seventy-two hours after the onset of symptoms, so mosquito control can provide an important measure of control to ensure prevention of secondary Venuzuelan equine encephalitis following either intentional or natural outbreaks of VEE. 

Rift Valley fever occurs primarily in sub-Saharan Africa where it is transmitted by mosquitoes. If a terrorist were to use Rift Valley fever, it would be dispersed as an aerosol. One troubling thing about a terrorist attack using this virus is that humans and domestic animals can become infected by aerosol means and a resident mosquito population can continue the assault. Defense against Rift Valley fever must include mosquito control.

Mosquito Control. Cultural practices commonly followed in the production of rice over most of the rice-producing areas of the southern states have created such favorable conditions for the multiplication of certain species of temporary water mosquitoes that the mosquito is probably the most important insect problem of this area. 

Because of the nondrifting qualities of the granular materials, they can be applied under conditions of greater air movement than fine sprays or dusts. This means that airplanes are not limited to operating a few hours at dawn or dusk but can be used many more hours a day. This in turn should permit more efficient use of airplanes. Each of the above factors should result in lower costs of application of mosquito control materials and make practical the use of control measures over greater areas. 

Uses Preparation of insecticides, brightening agents, and surfactants. Derived from industrial and experimental coal gasification operations where the maximum concentrations detected in gas, liquid, and coal tar streams were 2.1, 0.22, and 10 mg/m respectively (Cleland, 1981). May be present in commercial insect repellents containing aromatic solvents used for mosquito control (Dutta et al., 1998).
