Ants Data from How to fight multiple enemies: target-specific chemical defences in an aposematic moth
2017
Animals have evolved different defensive strategies to survive predation, among which chemical defences are particularly widespread and diverse. Here we investigate the function of chemical defence diversity, hypothesizing that such diversity has evolved as a response to multiple enemies. The aposematic wood tiger moth (Arctia plantaginis) displays conspicuous hindwing coloration and secretes distinct defensive fluids from their thoracic glands and abdomen. We presented the two defensive fluids from lab-reared moths to two biologically relevant predators, birds and ants, and measured their reaction in controlled bioassays (no information on colour was provided). We found that defensive flui…

Differences in composition between the ‘neck’ (a) and abdominal (b) fluids of wood tiger moths. Neck fluids have a richer chemical profile, with their main compounds being carboxylic acids (see Table II in Supplementary Material 5). Photos: Janne Valkonen.

Bird (a, b) and ant (c) response to pure pyrazine. Birds ate fewer oats soaked with 2-sec-butyl-3-methoxypyrazine (a; both in a concentration of 1ng/µl (P) and 0.1ng/µl (Pb)). Also, they tended to have longer latencies to approach pyrazine-soaked oats (both concentrations pooled) than control oats (b). Ant response to 2-sec-butyl-3-methoxypyrazine was, in contrast, not different from that to the control sugar solution (c).
