摘要
8年来,土蝗(小车蝗、笨蝗)在喀左部分山地、草场、农田暴发成灾,造成几百公顷农田毁种,每年直接经济损失可达20—30万元;更为严重的是,现已蔓延到建昌县岭龙塔乡为害。关于土蝗的研究,国内进展较慢。
Relations between growth of Haplotropes brunneriana and meteorological factors are studied,and the temperature,humidity and accumulated temperature during various age classes aredetermined.Based on these results,the long-range forecasting models for the occurence degre-es of the pest are established.
