籼稻比粳稻有利于二化螟的生长发育。杂交稻对三化螟和二化螟的生长发育都比常规籼稻有利,取食杂交稻的种群繁殖率可超过食常规籼稻的1～2倍。水稻品种生长期的长短,及其生长发育各阶段,与各地稻螟各世代各虫态的对应状况,是稻螟种群盛、衰的关键。对应状况适宜于稻螟为害繁殖时,其种群数量可数十倍于不适宜时的种群数量。研究水稻品种与稻螟种群消长的关系,应着重研究、协调各地水稻苗情与稻螟虫情的对应状况。
Indica than japonica rice is conducive to the growth and development of the rice stem borer. Hybrid rice is more beneficial to the growth and development of the rice stem borers, Chilo suppressalis (Walker) and the rice stem borer Chilo suppressalis than conventional indica rice. The population reproduction rate of hybrid rice can be increased by 1 ~ 2 times than conventional rice. Rice varieties of the growing period, and its growth and development of each stage, and the corresponding status of each stage of the rice stem borer is the key to the success of the rice borer population Sheng, decline. Corresponding situation is suitable for rice borer harm breeding, its population can be several times the number of unsuitable population. Studying the relationship between the rice varieties and the population growth and decline of rice stem borer, we should focus on research and coordination of rice seedling situation and rice borer insects situation corresponding situation.
