二化螟水稻类群与茭白类群成虫羽化节律和交配节律研究
The adult emergence rhythm and mating rhythm of rice host population and water-oats host population of the rice stem borer, Chilo suppressalis.
【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。
【Abstract】 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 population occurred around 4\^5 h after lights were switched off, but that of water\|oats host population occurred around 7\^0～7\^5 h after lights were switched off.
