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.

重寄生蜂（hyperparasitoid）B. galactopus对毛虫体表气味的偏好性研究：涵盖两类处理组合：（1）被C. glomerata寄生与未被寄生的菜青虫（P. brassicae）；（2）被H. ebeninus寄生与未被寄生的菜青虫（P. brassicae）。本研究通过Y型管嗅觉仪（Y-tube olfactometer）实验对该偏好性进行检测。实验所选用的处理组合基于以下假说：重寄生蜂可利用毛虫体表气味，而该气味至少部分由其体表微生物组（external microbiome）决定。
