| 摘要: |
| 对收虫箱收集得到的肚倍夏迁蚜，在室外直射光、室内散射光和室内黑暗条件下研究其贮留情况。结果发现，随贮留时间的延长，迁飞率降低，死亡率明显增大，单头蚜平均产蚜量下降，产蚜率增高；夏迁蚜平均产越冬侨蚜12.5头，随贮留时间延长，释放后平均产蚜数减少。直射光下夏迁蚜2h死亡率达98.94％．7月份自然高温不会导致夏迁蚜大量死亡，在40℃下半致死时间为4.91h．夏迁蚜的合理贮留条件为室内散射光（阴凉条件）下贮留1.56d，根据夏迁蚜的日迁飞习性，人工释放宜在贮留的第二天下午4:00后进行。 |

| Favorite Conditions for the Storage of the Summer Migrant Kaburagia rhusicola Takagi |

| Abstract: |
| The colonization of summer migrant Kaburagia rhusicola Takagi on Erythrodontium leptothallum(C.Muell) is a key link to the culture of Chinese gall aphids.In this study the gallnut put in a special box and the migrated aphid are stored in box for
some time.The favorite conditions to increase colonization rate are studied.The research
reveals that as the storage time increases, both colonization rate onmosses andmortality
increase and so does the birth rate.The average number of oviposition is 12. 5 per summer migrant and will decrease as the storage time increases.The death rate is 98. 94%
after the summerm igrant is exposed to sunshine for 2 hours.The natural extreme high
temperature in July does not cause obvious decrease of the aphid population and the semi-death rate time is 4. 91 hours under the temperature of 40℃.The favorite condition
for the storage of summerm igrants is 1. 56 days in room in indirect light.The summer
migrants should be released on messes after 4: 00 Pm in the second storage day. |
