Raw Y-tube olfactometer data

Preference of the hyperparasitoid B. galactopus for caterpillar body odours: of (1) C. glomerata parasitised ­­­­­and unparasitised P. brassicae caterpillars. (2) H. ebeninus parasitised ­­­­­and unparasitised P. brassicae caterpillars This was tested with Y-tube olfactometer tests. Tested combinations were selected according to the hypothesis that hyperparasitoids can use caterpillar body odours, which are (at least partially) determined by the external microbiome.
