| Résumé : |
A major goal of integrated pest management (IPM) is to maintain pest populations below economic thresholds while utilizing suitable techniques to protect both the environment and nontarget species. Assessment of pest population dynamics requires an understanding of the soil-plant-atmosphere continuum. The immediate environment in which a pest survives can be characterized by a number of climatic variables such as rainfall, radiation, temperature, relative humidity and wind speed and direction and soil variables including soil moisture, soil temperature etc. Cultural control of pests involves manipulation of these environmental variables to make them less favorable to the pest. Design of appropriate IPM techniques also requires knowledge of decision rules used by farmers to guide pest management actions, types and quantities of resources used in pest management and farmer perceptions of the economic efficacy (expected profit or reduction in unit cost of production) of indigenous management methods. Improvements that can be obtained from the application of alternative non-indigenous methods of pest management depend on crop value, cost of new inputs, productivity gain, risks associated with the use of new IPM techniques and the threshold levels and doses of insecticide required for effective control of pest damage. |
