| 摘 要： | 对泰安郊区小麦田蚜虫病原真菌和寄生蜂的发生情况进行了2年的调查,探讨了两类天敌的发生与气候因子和生物因素的关系。结果显示:麦蚜真菌病的发生水平与温度和降雨量成显著的正相关关系,与蚜虫密度成极显著的负相关。寄生蜂的寄生率与温度成极显著的正相关,而与蚜虫密度、相对湿度和降雨量均成显著的负相关。定量地描述了感菌有翅蚜在整个真菌病发生期间所发挥的作用。

| Abstract: | Based on two years' survey on the occurrence and epizootics of two natural enemies of cereal aphids,entomophthoralean fungi and hymenopterous parasitoids,the relationship between the natural enemies and weather conditions and biological factors were presented in this paper.Fungal infection was positively related to temperature and rainfall significantly,but negatively related to aphid density.Significant negative correlation between the mortality caused by parasitoids and aphid density,relative RH and rainfall were found.But the occurrence of parasitoids was positively related to temperature.Meanwhile,the important role of the alatae infected with fungi during epizootics was quantitatively described. |
