Table 2.

Onion thrip populations used in this study and their susceptibility to spinosad.

Population Name	LC₅₀ (Range) ppm ^a	Slope ^a	RR₅₀ ^b
S	0.6 (0.5–0.7)	1.6 ± 0.2	1.0
MR (selected)	117.2 (92.2–167.6)	0.1 ± 0.0	212.7
HR	23258.0 (15660.1–55825.2)	0.001	42,210.6

^a The values were calculated using Probit model. ^b The values were calculated by dividing the LC₅₀ by the S population LC₅₀.
