Behavioral responses of female H. sylvanidis to freshly killed T. confusum larvae treated as follows (N = 40 per stimulus): (i) untreated, (ii) extracted with n-hexane, (iii) extracted with n-hexane and treated with an un-fractionated larval extract of T. confusum (½ LE), (iv) extracted with n-hexane and treated with the fraction of methyl alkanes from fractionated T. confusum crude larval extract (½ LE). a) Host recognition rate (100% ≙ 40 successful host recognition events per stimulus) was analyzed by the test for equality of proportions followed by pairwise comparison of proportions with Bonferroni-Holm correction. Different letters indicate significant differences at P < 0.05. b) Mean searching time until successful host recognition was analyzed by Kruskal-Wallis test (ns = not significant, P > 0.05)
