    REMAKABLE ENHANCEMENT OF CYHALOTHRIN UPON LOADING INTO SILVER NANOPARTICLES AS LARVICIDAL
    (IJCAS, 2016-01) Abouelkassem, Sherif; El-Borady, Ola M; Mohamed, Mona B.
    This work has been devoted to develop a novel synthetic scheme to produce pesticide nanocomposite of very high efficiency compared to its original ones. laboratory experiments conducted in NanoTech. company, Dreamland, October city, Egypt and Department of plant protection, Fac. of Agric. Alazhar Univ. Assiut. Egypt. The method is based on using silver nanoparticles (AgNPS) as a pesticide carrier by loading pyrethroid pesticide cyhalothrin (CYN) into the surface of prepared AgNPS. The nature of binding of the pesticide into the nanoparticles surface has been investigated via TEM and FT-IR techniques. The new formulation of the pesticide nanocomposite AgNPS@CYN has been tested for its larvicidal property against three strains larvae of Culex pipiens (C. pipiens) (i.e. susceptible, field and tolerant strains). Our findings indicate that silver- cyhalothrin nanocomposite is more efficient in controlling mosquito larvae than that of free cyhalothrin. The required concentration for mosquito control decrease more than 100 times. This approach might be successful ones for safer pesticide and clean for the environment.
