Abstract: The sensilla of nematode are mainly arranged in anterior and end portions of the body. The main concentration of sensilla is at the anterior end of nematodes. Amphidial secretions are closely related to the nematode sensory perception. Chemotaxis plays an important role in foodfinding, matefinding, and other aspects of nematode interactions. Nematode chemotaxis contains the response to host plants, and sex pheromones attraction. Electrophysiological technology makes up for the limitations and disadvantages of agar plate behavioral bioassays, which provides a better method and technique for analyzing the response of nematodes to chemical stimulation. As chemotaxis plays an important role in activity and life history of plant parasitic nematodes, studies on chemotaxis offer references for developing novel and non-environmentally hazardous control methods. This review focuses on nematodes sensilla, chemoreception, electrophysiological technique and control potential.
