Green biological control of Artemisia herba alba essential oil and its insecticidal effect against Culex pipiens
摘要
This work aims to evaluate the potential of Artimessia herba alba essential oil (EO) as a green biological control agent against Culex pipiens mosquitoes. Using gas chromatography-mass spectrometry (GC–Ms), the oil was shown to contain 47 different compounds, including: Carvone (54.68%), D-Limonene (14.59%), and 1,8-Cineole (7.06%) respectively. When applied in doses at 15, 20, and 30 µg/l during the fourth larval stage, the oil demonstrated larvicidal effects, The lethal concentrations were calculated with their confidence limits and their values were of 27,62, 23,95 and 20,74 µg/l for LC50, while the LC90’s were 45,20, 37,67 and 29,58 µg/l after 24, 48, and 72 h, respectively. The botanical extracts of A. herba alba essential oil also affected the reproductive potential, fertility, and egg-hatching of the larvae. These findings suggest that A. herba alba essential oil may be effective at controlling mosquito populations without posing a risk to human health and the environment.
