Chemical pesticides are often applied indiscriminately to control vectors, which led to development and unfavorable effects on beneficial organisms. Worldwide, phytochemicals and plant extracts have a multitude of medical uses and may be employed to remove a wide range of germs and pests. Environmentally friendly nanoparticle manufacturing and nanotechnology are the newest trends in a number of sectors. Utilizing a green method, Achillea fragrantissima extract (AcF) was employed to prepare copper oxide nanoparticles (CuONPs@AcF). Copper oxide nanoparticle was characterized using zeta potential, DLS and transmission electron microscope (TEM). During the study of the AcF extract effect against larvicidal and adulticidal, we found that the effect of AcF extract was less than CuONPs@AcF. Also, we studied the effect of AcF and CuONPs@AcF against the female mosquito's fertility. The effect of the tested substances on the female Culex pipiens ovary was improved by the ultrastructure.KEY WORDS: Nanoparticles green synthesis, Copper oxide, Mosquito, Achillea fragrantissima extract.Bull.

Effective mosquito repellents can limit the transmission of vector-borne diseases to humans. Consequently, there is an urgent need to develop mosquito control strategies that prioritize eco-friendly and cost-effective repellents. Essential oils (EOs) have enormous potential for mosquito repellency. Here, cinnamon, basil, eucalyptus, and peppermint EOs were investigated for adulticide and repellency properties against Culex pipiens as well on the oviposition behavior of gravid females from laboratory (lab test) and field (field test) populations. Cinnamon oil was an effective oviposition deterrent regardless of the population and had high adulticidal activity with toxicity index of 75.00% at 24 h of exposure, relative to deltamethrin. In addition, it exhibited effective repellency at 98.01% and 71.22% at 6.67 and 1.71 µl/cm2, respectively. Peppermint oil had the least adulticidal activity with toxicity index of 6.2% at 24 h, and it resulted in low repellency at 70.90% and 50.64% at 6.67 and 1.71 µl/cm2, respectively. On average, basil and eucalyptus oils showed some adulticidal efficiency, repellency, and oviposition deterrent activity. For all treatments, the oviposition deterrent index values of gravid females from natural populations (field test) were lower than those from lab-reared (lab test) females. Different ratios of monoterpenoids, phenylpropanoids, and fatty acids in the EOs tested likely account for the activity variations observed. Our results suggest cinnamon, basil, eucalyptus, and peppermint EOs, which are widely available, economical, and eco-friendly, with good potential for mosquito control strategies.
