Honey bee stinger venom delivery mechanism

Overview

Researchers from Macquarie University and the University of New South Wales have identified the mechanical process by which honey bee stingers deliver venom. Through high-speed videography and the use of clear gel to mimic human tissue, scientists discovered that the stinger functions as an autonomous, double-piston micropump.

The mechanism relies on a system of lancets and flexible valves that act as reciprocating pistons. As the barbed stinger embeds in a target, it can undergo autotomy, breaking off from the bee to function independently. The internal valves change shape to create pressure, ensuring a continuous flow of venom rather than a pulsed output, even after the bee has departed.

This study, published in the Proceedings of the National Academy of Sciences (PNAS), suggests that this biological design could inspire the engineering of miniature liquid-delivery devices for medical or laboratory applications.
