摘要
蒙古跳甲是广泛分布于内蒙古西部地区的食叶性害虫之一，危害多种寄主植物，特别是对沙柳造成了极大的危害。为对其发生期进行预测预报，室内测定了蒙古跳甲各虫态的发育起点温度及有效积温。蒙古跳甲卵、幼虫、蛹及全世代的发育起点温度分别为6．7±1．9℃、4．8±0．4℃、4-0．8℃、5．6±0．7℃；有效积温分别为181．9±25．3日度、237．5±3．9日度、153．3±8．6日度、706．1±30．8日度，据此估算出蒙古跳甲在鄂尔多斯市1年发生2～3代。
A. deserticola Weise is one of the important defoliators which distributed in western Inner Mongolia, especially damaged Salix psammophila badly. In order to predict its population dynamics, the development zero temperature and effective accumulated temperature ofA. deserticola Weise were tested at laboratory. The development zero temperature of egg, larval, pupa and adult were 6.7±1.9℃, 4.8±0.4℃, 4±0.8℃ and 5.9±0.7℃ separately. The effective accumulated temperature of egg, larval, pupa and adult were 181.9 ± 25.3, 237.5 ± 3.9, 153.3 ± 8.6 and 706.1±30.8 day - temperature respectively. A. deserticola Weise may fulfill 2 ～ 3 generations in a year according to the effective accumulated temperature in Dongsheng area.
