. Application of carbon or bactericides had only minor impact on the nematode community. In contrast, the fungicide was very toxic to non-target organisms and greatly reduced the abundance of most nematode species, although Acrobeloides buetschlii showed tolerance and greatly increased in number. At both sites

received only rainfall. For individual nematode taxa, soil layer and watering regime were the main factors discriminating between treatments, while initial inoculum had a larger in uence than soil type. Acrobeloides was most affected by the watering regime, being more abundant under variable water

-persister (cp) scale and on their trophic roles. At the last sampling date (December 2004), Mesorhabditis and Acrobeloides were positively associated with NH + 4 , while Panagrolaimus and Plectus were negatively correlated with certain phospholipid fatty acids (PLFA). Microbial-feeders were in general

cultures of two species of bacterial-feeding soil nematodes are described. Mesodiplogaster lheritieri populations develop rapidly because they produce eggs ear- ly and have a short generation time (4 days). Although Acrobeloides sp. has a longer generation time (11 days), it also has a longer reproductive

two rhabditid nematodes, Panagrolaimus sp. and Acrobeloides sp., from Dr. W. L. Nicholas, Division of Botany & Zoology, School of Life Sciences, Australian National University, Canberra. The nematodes were cultured on nutrient agar with bacterial food (E. coli K-12) at 20 ° C . Adults were taken from

The lip region in Acrobelinae is conical, sometimes significantly elongate quite apart from the impres- sion of elongation conferred by the development of lip appendages-labial and cephalic pro- bolae-characteristic of the subfamily

Acrobeloides tricornis (Thorne, 1925) Thorne, 1937 was found to possess five incisures in the lateral field, rendering its differentiation from some other species of the genus less clear. The lip
