1LC50 values in ppm
295% CI, toxicity of insecticide is considered significantly different when the 95% CI fail to overlap; no significant difference (a) and significant difference (b) compared with no-injection mosquitoes.
3Ratios were calculated by dividing the LC50 of the GFP or target gene injection mosquito groups by the LC50 of the non-injection mosquito group of same mosquito strain.
