Due to the worldwide importance of rice as a crop plant, the biology of rice pests is of great interest to agricultural research. This timely book brings together contributions from the fields of entomology, agronomy, population ecology, and biostatistics to provide a comprehensive survey of rice-insect interaction. Among the topics discussed are - crop loss assessment - economic thresholds and injury levels for incest pests - mosquito leafhoppers and planthoppers population dynamics - pheromone utilization - techniques for predator evaluation - chemical based for insect resistance - applications of tissue culture - systems analysis and - rice pestmanagement. With its emphasis on experimental techniques of pest analysis and control, Rice Insects: Management Strategies will be a valuable reference for researchers and practitioners alike.
