松嫩平原淡黄虻种群日吸血活动的时空动态研究

Spatial pattern and temporal dynamics of Atylotus pallitarsis population in Songnen Plain.

淡黄虻是松嫩平原虻虫中的优势种 .对其吸血活动的观测发现 ,其种群数量与温度、湿度呈显著相关 ;吸血高峰时间出现在 14∶0 0左右 ,种群的聚集度和扩散度也在此时达到最大 ;种群不仅呈聚集分布 ,而且呈聚集型扩散 ;种群聚集分布以疏松的小集团形式存在 ,其个体呈随机分布 .

The spatial pattern and its time series dynamics of Atylotus pallitarsis population were examined in this paper.The results showed that the amount of this population was closely related to temperature and humidity,and its blood peak time appeared at about 14∶00 o'clock in the afternoon.The population cattles was aggregated distribution and emigration thoroughout the day,the aggregated distribution pattern was loose mass community,the distribution of insects in the community was at random.
