The role and functioning of the anterior chemosensory organs of plant parasitic nematodes is examined, with particular emphasis on the amphids. The morphology of the amphids is discussed primarily in the context of the changes in the ultrastructure associated with different life stages. The involvement of amphidial secretions in chemoreception and the behavioral and electrophysiological analyses of nematode responses to semiochemicals are discussed with special reference to research on sex pheromones. These research techniques, combined with the use of lectins and antibodies, provide information on nematode sensilla that may lead to novel control strategies for economically important plant parasitic nematodes based on perturbing nematode sensory perception to prevent host or mate location.

植物寄生线虫中的化学感受。

检查了植物寄生线虫的前化学感觉器官的作用和功能，特别着重于两栖动物。主要在与不同生命阶段相关的超微结构变化的背景下讨论了两栖动物的形态。讨论了两性分泌物在化学感受中的参与以及线虫对化学信息素反应的行为和电生理分析，并特别参考了性信息素的研究。这些研究技术与凝集素和抗体的使用相结合，可提供有关线虫感官的信息，这些信息可能会基于扰动线虫的感官知觉来防止寄主或伴侣的定位，从而为经济上重要的植物寄生线虫提供新的控制策略。
