Vector-borne diseases caused by mosquitoes are one of the major economic and health problems in many countries. The Aedes aegypti mosquito is a vector of several diseases in humans like yellow fever and dengue. Vector control methods involving the use of chemical insecticides are becoming less effective due to development of insecticides resistance,(More)
Mosquitoes in the larval stage are attractive targets for pesticides because mosquitoes breed in water, and thus, it is easy to deal with them in this habitat. The use of conventional pesticides in the water sources, however, introduces many risks to people and/or the environment. Natural pesticides, especially those derived from plants, are more promising(More)
Mosquito vectors are responsible for the transmission of parasitic and viral infections, including loss in commercial and labor outputs, particularly in developing countries with tropical and subtropical climates. The aim of the present study is to evaluate the adulticidal and smoke toxicity of Cipadessa baccifera (Roth) against three important mosquitoes(More)
Ultraviolet light (UV-B), which emits radiation in the range of 280-315 nm, has been used worldwide in light trapping of insect pests. In this article, we test the hypothesis that one of the duration of UV-B exposure has a differential impact on oxidative stress marker enzymes in Spodoptera litura. Effect of UV-B exposure on total protein and antioxidant(More)
Mosquito control is facing a threat due to the emergence of resistance to synthetic insecticides. Insecticides of botanical origin may serve as suitable alternative biocontrol agents. The present study is to evaluate adulticidal activity of Clausena dentata plant extract against Aedes aegypti and Culex quinquefasciatus mosquitoes. The adult mortality was(More)
BACKGROUND The resistance status of malaria vectors to different classes of insecticides used for public health has raised concern for vector control programmes. Alternative compounds to supplement the existing tools are important to be searched to overcome the existing resistance and persistence of pesticides in vectors and the environment respectively.(More)
