• Populations of S. furcifera and N. lugens were studied for 3 seasons of rice cultivation at Kalugomuwa, Kandy District, Sri Lanka. In 2 of the 3 seasons, S. furcifera was superior in abundance to N. lugens. Both species were similar in seasonal trend of adult population to each other, but the proportions of brachypterous forms to the whole adults fluctuated in different ways between the 2 species. N. lugens was less aggregative in spatial distribution than S. furcifera. Parasitic activities of Elenchidae, Dryinidae, Pipunculidae and Nematoda were sometimes considerably high, but they were neither persistent nor regulative against the host population.
