中文摘要：比较研究了二化螟Chilosuppressalis(Walker)水稻类群与茭白类群成虫的羽化和交配节律 ,研究结果表明 :两类群的羽化节律大体一致 ;但交配节律存在明显差异 :水稻类群成虫的交配高峰出现在熄灯后 4.5h ;茭白类群成虫的交配高峰出现在熄灯后 7.0～7.5h。
英文摘要：The emergence and mating rhythms of rice and water-oat host populations of the rice stem borer were studied.The emergence rhythms of both populations were almost the same,but their mating rhythms were significantly different.The mating peak of rice host p
