TABLE 4.

Relative potencies of several Cry1 proteins against unselected strains of P. xylostella^a

Protein	Result in the indicated test for the following strain:
	LAB-V			LAB-PS		ROTH (bioassay B2)	Geneva (leaf dip)d	Reunion Island (leaf dip)e
	Bioassay B1	Bioassay B2	Diet overlayb	Bioassay B1	Bioassay B3c
Cry1Aa	6	5	6	5	26	0.6	67	3
Cry1Ab	37	100	100	100	46	50	33	100
Cry1Ac	100	82	34	34	100	100	18	3
Cry1Ca	15	14	13	11	7	3	5	8
Cry1Da	0.5	0.9	<1	2	4	0.4	100	3

^aRelative potencies were estimated by assigning a value of 100 to the most potent Cry protein (the one that showed the lowest LC₅₀). The potency of all others was calculated by dividing the lowest LC₅₀ by their LC₅₀ and multiplying the result by 100.
