Abstract Variables associated with the seasonal abundance of members of a prey complex consisting of Chironomidae, Corixidae and Crustacea, and of a predator guild including Belostomatidae, Dytiscidae, Hydrophilidae and Notonectidae sampled from California rice fields were evaluated by multiple regression analysis. Variables included water temperature, rice plant stand and potential predator-prey interactions. Regression equations using water temperature and rice plant stand as independent variables described the seasonal abundance of both the prey complex (F = 5.619; P = 0.025) and the predator guild (F = 9.037; P = 0.005). Predator-prey interactions further modified many of the seasonal patterns of the organisms observed.
