Raw Y-tube olfactometer data

<strong>Preference of the hyperparasitoid </strong><em><strong>B. galactopus </strong></em><strong>for caterpillar body odours: </strong>of (1) <em>C. glomerata </em>parasitised ­­­­­and unparasitised <em>P. brassicae </em>caterpillars. (2) <em>H. ebeninus </em>parasitised ­­­­­and unparasitised <em>P. brassicae </em>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.
