摘要Mosquitoes(Diptera:Culicidae)are vectors of various pathogens of public health concern,but replacing conventional insecticides remains a challenge.In this regard,natural products represent valuable sources of potential insecticidal compounds,thus increasingly attracting research interest.Commiphora myrrha(T.Nees)Engl.(Burseraceae)is a medic-inal plant whose oleo-gum resin is used in food,cosmetics,fragrances,and pharmaceuticals.Herein,the larvicidal potential of its essential oil(EO)was assessed on four mosquito species(Aedes albopictus Skuse,Ae.aegypti L.,Anoph-eles gambiae Giles and An.stephensi Liston),with LC50 values ranging from 4.42 to 16.80 μg/mL.The bio-guided EO fractionation identified furanosesquiterpenes as the main larvicidal compounds.A GC-MS-driven untargeted metab-olomic analysis revealed 32 affected metabolic pathways in treated larvae.The EO non-target toxicity on Daphnia magna Straus(LC50=4.51 μL/L)and its cytotoxicity on a human kidney cell line(HEK293)(IC50 of 14.38 μg/mL)were also assessed.This study shows the potential of plant products as innovative insecticidal agents and lays the ground-work for the possible exploitation of C.myrrha EO in the sustainable approaches for mosquito management.
