摘  要:
在新疆乌鲁木齐和呼图壁对苜蓿叶象甲第一代自然种群发育积温、发育期预测和种群数量动态预测的研究。结果表明,苜蓿叶象甲在乌鲁木齐地区全世代的发育时间87d,需≥10℃积温为1 789.3℃·d。直方图法分析,理论发生代数乌鲁木齐为2.14~2.96代(呼图壁为2.21~3.05代),呼图壁第一代卵、2龄、3龄、4龄幼虫和蛹期的理论高峰时间符合田间实际调查结果。苜蓿叶象甲防治最佳时间为5月17日~5月30日。

摘  要:
The accumulative temperature of natural population development for the first generation from Hypera postica(Cyllenhal),prediction of development stage,prediction of dynamic state of population density in Hutubi area and Urumqi area,Xinjiang were investigated.The result indicated that the development time of the whole generation from Hypera postica(Cyllenhal)in Urumqi area was 87 d,≥10 ℃ accumulative temperature was 1 789.3 ℃·d.Histogram analysis showed that theory occurrence generation was 2.14-2.96(2.21-3.05 in Hutubi).The eggs of first generation,2nd instar,3rd instar,4th instar larvae and the theoretical ruch hour of pupal instar was accordant with the investigaled result in field in Hutubi area.The best prevention period of Hypera postica(Cyllenhal)was between May 17 and May 30.
