Abstract
Extensive and continuous use of synthetic chemical insecticides led to environmental hazards to non-target organisms, and development of insect’s resistance. The present study evaluated essential oil of Nigella sativa seeds as a friendly larvicidal measure for Culex pipiens and Musca domestica vectors of infectious diseases. The N. sativa components essential oil was analyzed by GC-MS. Sixteen components were identified. The selenium nanoparticles (SeNPs)with N. sativa essential oil were prepared to form N. sativa SeNPs and proved by UV-Spectrophotometer, FT-IR, and SEM. The droplet size of nanoemulsion was 65±11.4 nm. The bioassay showed that N. sativa essential oil and its nanoparticles were more effective against larvae of Cx. pipiens than those of M. domestica.
