EFFECT OF pH, OXYGEN AND TEMPERATURE ON THE ACTIVITY AND SURVIVAL OF HIRSCHMANNIELLA SPP. BY J. O. BABATOLA1) Imperial College Field Station Sunninghill. Berks SL5 7DE England. Activity and survival of three Hirschmanniella species were investigated from pH 3 to 9 at 25°, and under aerobic and anaerobic conditions at four different temperatures. Activity and survival of all three species were poorest at pH 3 and at 10°. The ability of the nematodes to survive anaerobic conditions suggests that they are facultative anaerobes. At certain seasons of the year, the roots of lowland rice plants (Oryza sativa L.) are subjected to anaerobic or nearly anaerobic conditions because fields are flooded. However, Van Raalte (1943) observed active transport of oxygen to the roots from leaves through parenchyma cells showing that the rice root could be oxygen-rich in anaerobic conditions. An actively growing rice crop is impor- tant for rapid population increase of Hirschmanniella spp. (Babatola, 1977). Yokoo & Su (1966) reported that H. oryzae (Soltwedel) was most abundant within roots when fields are flooded. Kawashima (1962) and Nakazato et al. (1964) also found that H. oryzae was more abundant in damp rice fields than in well-drained ones and observed
