Behavior test with turnip sawflies. (VIDEO)
Caption
The sawflies were difficult to train as they didn’t respond to a typical sweet sugar solution and may feign death when touched. The researchers were able to persuade them to participate in the test by feeding extracts from their favorite plant, the harlequin glory-bower, direct to their sensory mouth parts (palps) as a reward. In this clip the sawfly's proboscis extension reflex ("PER"), is the trained response to a conditioned stimulus ("CS"), a unique odor which it learned to associate with getting the reward.
