How long does the sting pump apparatus continue to pump venom after a worker bee stings?

• A. 10 to 15 seconds
• B. 30 to 60 seconds
• C. 1 to 2 minutes
• D. 5 minutes

Answer: (B)

The correct duration for how long the sting pump apparatus of a worker bee continues to pump venom after a sting is typically 30 to 60 seconds. This is because the venom sac, which is connected to the stinger, can rhythmically contract and push venom into the victim for this approximate timeframe after the sting occurs. A bee's stinger contains a barbed structure that becomes lodged in the skin of its target upon stinging. As the bee attempts to fly away, the stinger and venom sac remain attached, allowing the venom to continue to flow into the target even after the bee has detached. This pumping mechanism is an evolutionary adaptation that maximizes the delivery of venom in defense of the hive or when the bee is provoked. The other choices suggest longer or shorter durations than what is typically observed. For example, while some might think that a bee could pump venom for several minutes, the physiological mechanics of the venom sac and stinger do not support such long durations. Similarly, suggesting that the pumping action lasts only 10 to 15 seconds underestimates the capability of the bee's anatomy to deliver venom. Therefore, 30 to 60 seconds is the most accurate timeframe for this snapping mechanism.
