ABSTRACT
Objective To explore the expression characteristics of cytochrome P450(CYP)candidate genes(CYP6M3, CYP6Y1,CYP6P5,CYP4H14,CYP4G17,CYP12F16)in Anopheles sinensis.Methods The samples were collected from dif-ferent developmental stages(eggs,larvae,pupae and adult mosquitoes(females and males)),and different tissues(salivary glands,malpighian tubes,midguts,ovaries,and fat bodies)of An.sinensis and the female adult mosquitoes exposed by differ-ent insecticide doses(0,1.25,3.75,6.25,12.5μg/bottle)and time points(0,5,15,30,60 minutes),then the total RNA was extracted. Quantitative reverse transcription PCR(qPCR)assay was used to analyze the relative expressions of six CYP genes in An.sinensis at different developmental stages,tissues and different insecticide exposure doses and time.Results The expressions of CYP6M3 and CYP6Y1 in the male adult mosquitoes were the highest,the expression of CYP6M3 gene in the males was 35.1 times higher than that in the females,the expression of CYP6Y1 in the males was 61.4 times higher than that in the females;the expression level of CYP4H14 in the larvae was the lowest,the expression of CYP4H14 in the females was 22.5 times higher than that in the fourth instar larvae.The expressions of candidate CYP genes in different tissues of An.sinensis were significantly different,the expression of CYP6M3 in the malpighian tubule was 38.9 times higher than that in the ovary,the ex-pression of CYP6Y1 in the fatbody was 9.1 times higher than that in the ovary,the expression of CYP4G17 was 4.6 times higher than that in the ovary,and the expression of CYP12F16 was 4.4 times higher thanthat in the ovary.The exposure to different in-secticide doses and time showed some induction effects in the expressions of candidate CYP genes,which affected the expres-sions of candidate CYP genes in An.sinensis.Conclusion The expression of candidate CYP genes varies significantly in differ-ent developmental stages and various tissues of An.sinensis,and exposure to deltamethrin at various doses and time points af-fects CYP genes expression in An.sinensis.
