Table 2. Cerotoma trifurcata feeding damage on cucumber and soybean plants in laboratory choice-test feeding study.

Injury type	Cucumber	Soybean
	Mean (SEM)
*24 hours post-infestation*
% of plants with stem damage	0 a	100 b
% cotyledon area with distinct holes	0.11 (0.11) a	2.89 (1.09) b
% upper surface area of cotyledon scarred	0.33 (0.24)	NA*
% lower surface area of cotyledon scarred	0 a	32.22 (4.01) b
% of plants with damage to 1st true leaf	NA**	NA*
*72 hours post-infestation*
% of plants with stem damage	0 a	100 b
% cotyledon area with distinct holes	3.13 (2.19) b	4.61 (1.15) b
% upper surface area of cotyledon scarred	0.74 (0.32) a	61.89 (7.73) b
% lower surface area of cotyledon scarred	1.16 (0.73) a	52.78 (4.72) b
% of plants with damage to 1st true leaf	0 a	100 b

Means within a row followed by different letters are significantly different (P<0.05), two-sample t-test on the mean difference of arc-sine square root transformed data on percent damage for soybean versus cucumber.

* Cotyledons had not opened, so the upper surface of the cotyledon and first true leaf could not be evaluated.

** First true leaf was not apparent.
