摘　　要：水稻三化螟近年来在我县回升速度较快。给水稻生产造成严重威胁。几年来的研究表明，再度猖獗的主要原因是：（１）品种布局的调整，利于三化螟的发生；（２）种植新技术的推广，为再度猖獗提供条件；（３）常年冬季偏暖，气候条件适宜；（４）防治认识不足，造成三化螟危害逐年加重。据此提出农业防治、化学防治等防治对策。Rice scirpophaga incertulas has been rampant once again in the past few years and it is causing serious danger to rice production. A few years' research has shown that the rice breeds' local adjustment and the spreading of new planting technology contribute to the happening of scirpophaga incertulas. Furthermore, the warmer winter is beneficial to its reproduction. While the neglect of prevention and control of scirpophaga incertulas has finally resulted in more serious damages to rice year after year. In view of the above, some countermeasures, such as agriculture prevention and chemical control, are put forward.
