Comparison of Toxicity of Bifenthrin and DDT in Four Strains of the Navel Orangeworm (Amyelois transitella) with the Presence or Absence of the “Knock-Down Resistance” (kdr) Mutation in the para Gene

Population	Bifenthrin 48 h LC₅₀ (95% CI)	DDT 48 h LC₅₀ (95% CI)
ALM (kdr+)	7.45 (5.90–9.64)	259.85 (216.71–326.0)
FIG (kdr+)	7.20 (5.35–11.08)^a	—
R347(kdr+)	24.27 (18.19–33.09)	310.33 (249.37–424.29)
CPQ (kdr−)	0.38 (0.31–0.46)^a	25.32 (19.73–30.84)

Note.—LC₅₀, median lethal concentration; CI, confidence intervals; ALM, FIG, R347, and CPQ, populations of A. transitella used in the study.

LC₅₀ identified in Bagchi et al. (2016).
