| 摘 要： | 2008年4月底至6月初在山东禹城调查了小麦和3种牧草上的蚜虫和天敌种群密度。结果表明,麦蚜种群高峰期在5月中旬,寄生蜂和瓢虫的高峰期比蚜虫分别滞后5～10d和15～20d;麦蚜种群增长率与天敌种群密度变化呈负相关,其中与瓢虫的相关性达到显著水平;4月底至5月初小麦抽穗期是麦蚜种群爆发的关键时期,天敌密度低、害益比大是爆发的重要原因;4月底至5月初,牧草上的天敌密度是小麦上的2～3倍。牧草在麦蚜种群生态调控中具有潜在应用价值。

| Abstract: | Multi-population dynamics of aphids and natural enemies on winter wheat,alfalfa,perfoliate rosinweed and wintergrazer-70,were investigated in Yucheng City,Shandong Province of China.The results indicated that:the peak of multi-population of wheat aphids was in middle May,while that of parasitoids and lady beetles had time lags of 5-10 d and 15-20 d respectively;population growth rate of wheat aphids was negatively correlated with natural enemy population densities,and the correlation with lady beetle popula... |
