| 中文摘要: |
| 在室内测定科尔沁草原亚洲小车蝗在不同湿度对4种该草原优势植物的取食量。结果表明:亚洲小车蝗在50%～80%湿度下的取食量显著大于其他湿度,结合近地表5cm处草场湿度估测亚洲小车蝗单头单日取食量;同时考察亚洲小车蝗不同龄期的田间存活率,确定科尔沁草原亚洲小车蝗的防治指标为20.6头/m2。 |
| 英文摘要: |
| The consumption of 4 kinds of predominant plants in KeErqin grasslands by Oedaleus asiaticus were measured under different conditions of relative humidity(RH).The results showed that the consumption under conditions of 50%～80% RH was much more than that under other RH conditions.Based on the change of RH conditions in the experimental grasslands,the consumption per day was estimated.And based on the survival rate of O.asiaticus at different ages in the grasslands,the control index of O.asiaticus was finally estimated as 20.6 locusts/m2. |
