Decrease in the heartbeat frequency after the application of N. fodiens venom (NF) and S. araneus saliva (SA). a Treatment of the T. molitor heart with 10 μl of N. fodiens venom extract and 10 μl of S. araneus saliva. b Treatment of the frog heart with 40 μl of venom or saliva (registration of the heart contractile activity for 2 min). Statistically significant differences are indicated by asterisks (NF: Wilcoxon-test in a, n = 32; paired Student’s t-test in b, n = 30; SA: paired Student’s t-test in a, n = 40; Wilcoxon-test in b, n = 30) for intraspecific comparisons (*** p < 0.001) and black dots (unpaired Student’s t-test) for comparisons between NF and SA (• p < 0.05)
