SUMMARYFemale sex pheromone reception was inhibited in a bioassay by treating males of the beet cyst nematode, Heterodera schachtii, with the sulphydryl reagent, mersalyl acid. This effect was blocked by the sulphydryl group protectant, dithiothreitol, indicating the occurrence of sulphydryl groups in the receptor molecules and a role for sulphydryl groups in pheromone reception.

Abstract This chapter focuses on some of the principal techniques for analysing nematode behaviour and physiology, such as attraction/repulsion plate assays, pluronic gel assays, movement assays, electrophysiology, stylet activity, water content changes, oxygen consumption assays, collection of female sex pheromone, virgin females and males and viability tests, among others.
