The paper presents the preliminary results of catches of predators in pitfall traps around an irrigated rice field at IRRI, Los Banos, the Philippines, during the first half of the rainy season of 1998. The most common predators caught were spiders, carabids and ants. Results indicate that directional movement between the field and its surroundings, as well as total catches of predators, depend on farm operations and crop age. The bund may be an important source of predators for the young rice field.
