| Abstract: | Since the 1980's and especially the 1990's, outbreaks of the Oriental migratory locust in Hebei Province have increased in frequency, with outbreaks occurring earlier in the season. These changes are probably due to the influence of abnormal climate, agricultural ecology and human factors. In order to determine the causes of outbreaks five factors that influence population dynamics of the Oriental migratory locust in Hebei Province; weather, agricultural ecology, lake levels, river levels and human impacts, were analysed. Likely future trends of outbreaks of Locusta migratoria manilensis (Meyen) in Hebei Province are predicted. |
