1994～1996年对浙江省双季稻区稻水象甲Lissorhoptrus oryzophilus Kuschel春季迁飞的系统研究表明,以飞行肌发育起点温度13.8℃以上的有效积温结合当地、当日起飞时段的天气情况预测越冬代成虫的迁入峰期是完全可行的。越冬成虫的第1波下迁一般出现在有效积温达70～90日度时,主迁峰则视天气条件出现在积温达90～140日度时。越冬代成虫大量起飞的最适条件是气温>20℃且无风或微风,故起飞一般始于16∶00左右,在气温低于20℃时终止。早春及4月上中旬的降水可影响飞行肌的发育速率,从而影响第1波下迁的时间;4月下旬和5月上旬的降水则影响主迁峰的出现时间。
A systematic study on the spring migrations of Lissorhoptrus oryzophilus Kuschel in double cropping rice in Zhejiang Province from 1994 to 1996 showed that the effective accumulated temperature above 13.8 ℃ for flight muscle development predicted the overwintering generation Adult peak immigration is entirely feasible. The first wave of overwintering adult migratory generally appear in the effective accumulated temperature of 70 to 90 days, the main migration peaks depending on the weather conditions appear in the accumulated temperature of 90 to 140 days. The overwintering adult adults take off the most appropriate conditions are temperature> 20 ℃ and no wind or breeze, so the takeoff usually starts around 16:00, when the temperature is below 20 ℃ termination. Precipitation in early spring and mid-April can affect the rate of flight muscle development, thus affecting the time of the first wave of down-migration; the precipitation in late April and early May affected the appearance of the main migration peak.
