Parasitism causes changes in caterpillar odours and associated bacterial communities with consequences for host-location by a hyperparasitoid
Fig 1
Experimental setup for the caterpillar odour and microbiome collection.
Groups of eight C. glomerata parasitised or unparasitised caterpillars were placed in a glass jar with a restriction device. A dynamic air current was led through the setup and VOCs were trapped in a Tenax trap. After headspace (odour) trapping, the same caterpillars were subjected to the collection of their external and internal microbiome in PBS-Tween80 solutions.
