Effects of Cry1Ac protoxin and activated toxin on mortality of H. armigera larvae of resistant strain XJ10 and susceptible strain XJ.

Strain Form of Cry1Ac LC50 a (95% Confidence Limits) Resistance Ratio b
XJ protoxin 8.41 (6.31–11.25) 1
XJ10 protoxin 1233.91 (923.58–1665.62) 146.79
XJ activated toxin 7.16 (5.25–9.76) 1
XJ10 activated toxin 322.48 (248.42–417.66) 45.05

a Concentration killing 50% with 95% fiducial limits in ng Cry1Ac per g diet. b Resistance ratio, LC50 for XJ10 divided by LC50 for XJ.
