Assistant Professor of Biology Josh Martin coauthored the paper “Predatory behavior changes with satiety or increased insulin levels in the praying mantis (Tenodera sinensis)” published June 3 in the Journal of Experimental Biology. The paper discusses how animal behavior is controlled “by a combination of external stimuli and an animal’s internal state,” the abstract says. The authors describe how “sensory responsiveness and motor activity of a praying mantis (Tenodera sinensis) are changed as the insect feeds, leading to an altered hunting strategy. We further show that these changes can be induced by injection of insulin, which likely functions as a metabotropic indicator.”
