Technical Abstract: This review on plant parasitic nematode host finding and recognition begins with fundamental definitions of behavior terms relevant to nematodes followed by an analysis of the basic aspects of nematode movement within water films in the soil, on above ground surfaces, and within plant tissue. Special attention is given to the influence of soil texture and moisture, osmotic pressure, dissolved salts, temperature, and carbon dioxide gradients within soil and plant tissues. Other topics include the need to permit nematode movement in three dimensions during nematode behavior experiments, the requirement for continuous air channels within soil to establish long-distance gradients of volatile attractants and repellants, the occurrence of evidence for specific plant attractants within only a narrow range of nematodes and plants, the involvement of fixed action patterns in root penetration and plant tissue migrations, and the possible or attempted utilization of knowledge regarding nematode behavior in crop protection.
