Locomotion executed in direct reaction to physical contact is_________________?
Show answer Hide answer
Answer: B. Stereokinesis
Explanation
Stereokinesis describes locomotory movements triggered directly by physical touch or pressure against a solid surface. This behavioral response encourages insects to seek tight crevices where their bodies contact surrounding substrates. Physical contact provides sensory feedback that modifies the walking speed and direction of the navigating insect. Insects rely on various kinesis behaviors to find suitable resting sites and escape unfavorable environmental conditions. Thigmotaxis and stereokinesis involve behavioral orientation driven purely by tactile mechanical stimulation. Sensory receptors located on the insect antennae and body hairs detect direct physical contact with objects.
Pest management professionals use knowledge of stereokinetic behavior to design effective traps and monitoring stations. Many crawling pests hide in dark wall cracks because tactile stimulation satisfies their innate stereokinetic drive. Understanding physical orientation responses helps researchers study how insects navigate complex structural environments. Option A is incorrect because chemokinesis involves movement changes triggered by chemical or olfactory gradients. Option C is incorrect because hydrokinesis describes locomotion driven by humidity and moisture variations. Option D is incorrect because klinokinesis refers to turning rates changing in response to stimulus intensity.
