P. rapae and Pl. xylostella behavior on WT or transgenic (TR) isoprene-emitting Arabidopsis plants

Line	Development			Cafeteria
	Weight gain, mg	n	t test	Choice, %				n	Binomial test*
				1st	0.5 h	1 h	2 h
P. rapae
WT	46.9 ± 1.72	29	t = −0.741	54	52	53	53	100	z = −0.7
TR	49.8 ± 3.43	33	P = 0.462	46	48	47	47	100	P = 0.242
Pl. xylostella
WT	6.6 ± 0.26	22	t = −0.919	46	42	40	43	100	z = −1.9
TR	7.0 ± 0.33	23	P = 0.364	54	58	60	57	100	P = 0.028

Mean ± SE is shown for larval weight gain and percentage for the cafeteria choice-experiment. In the cafeteria experiment, the 1st choices as well as choices after 0.5 h, 1 h, and 2 h after the start of the experiment are shown. The number of independent replications is indicated by n.

*The results from binomial tests are shown for the time point, in which highest difference in choices between WT and TR were found. For the other time points P > 0.05.
