Mechanisms of Rice Planthopper Resistance to Insecticides

摘要: History of insecticidal control rice planthoppers in Asia and associated resistance development is summarized. Rice have developed against all the insecticides that were commonly used. Experiences past 30 years chemical many parts confirm use any kind insecticide for long time leads to resistance. Overseas migration may markedly affect status populations over distances, effects can be maintained at least until following year. It possible spread as a result intercrossing between resistant immigrant susceptible domestic populations. When are used major pest, such also produce selection pressure on potential pests. believed small brown planthopper (SBPH) one important factors behind recent outbreaks smaller BPH China. Pesticide-induced resurgence involves ecological physiological factors. Many pesticides stimulate reproduction (BPH), sublethal dosages increase its reproduction. Decimation natural enemy by an factor induction resurgence, but stimulation more responsible occurrence resurgence.
