Details are given on the comparative feeding behaviour and associated damage of Hirschmanniella oryzae, H. spinicaudata and H. imamuri on rice. The general pattern of feeding was the same for all 3 species with 4 distinct phases: (1) probing or exploration, (II) stylet penetration, (III) salivation and (IV) ingestion. The energy output involved in stylet penetration by H. spinicaudata was about 4 times that by H. imamuri and 53 times that by H. oryzae. Adults and juveniles of all stages invaded roots causing damage to the tips. Roots invaded by any of the 3 species were predisposed to secondary infection by rot-inducing micro-organisms.
