چکیده
Abstract The current work aims to improve the metal oxide characteristics for mosquito control. Un-doped and Y-doped CuO have been synthesized by simple chemical route. Structural, composition, morphological properties were characterized XRD, Raman spectra, EDX, SEM, TEM techniques. obtained results revealed that was strongly affected Y 3+ support, in which crystallite size decreased, surface area increased. Larvicidal performance assessed against Culex pipiens suggesting nanocomposite CuO/Y of higher efficiency (LC 50 = 7.67 mg /l, R 2 0.977) compared with pure CuO. Light microscopy SEM images exhibited larvae malformations owing using fabricated nanomaterials.

Background. Outbreaks of the West Nile virus infection were reported in Morocco in 1996, 2003, and 2010. Culex pipiens was strongly suspected as the vector responsible for transmission. In the North center of Morocco, this species has developed resistance to synthetic insecticides. There is an urgent need to find alternatives to the insecticides as natural biocides. Objective. In this work, the...

Methanol extracts of different plants namely, Trichodesma africanum (Boraginaceae), Cleome rupicola (Capparceae) and Ochradenus baccatus (Resedaceae), were tested for larvicidal activity against 4 instar larvae of Aedes caspius and Culex pipiens mosquitoes. All plant extracts tested against Ae. caspius showed 100% mortality at 10μg/ml except the stem of O. baccatus which showed 90% mortality. H...
