气象因素对凹唇壁蜂活动规律的影响研究

Study on the Influence of Meteorological Factors on Daily Activity of Osmia Excavata Alfken

经对试验结果进行分析，发现日平均温度是影响凹唇壁蜂出茧速率的主要气象因素，其次是日照时数和最高温度。成蜂出茧后，在访花活动期间，雌蜂的活动频率除了受花期的影响外，主要受日平均温度的影响，即温度越高，活动频率就越高，而与风速呈负相关。在阴雨较少的情况下花期温度是影响繁殖率高低的主导因素，其次为日照时数和平均风速。

The biological characteristics of Osmia. excavata Alfken is influenced greatly by the meteorological factors. the results of the study showed that the daily average temperature (DAT) is the most important factor influencing the occurrence from cocoon, and then the photoperiod, minimum and maxi mum temperature. After the occurrence of adults, the frequency of the activity of the female is affected mainly by DAT during the period of the flowering of apple tree, i.e. the higher the temperature, the more frequency of activity. However, the frequency of activity has a negative correlation to the velocity of wind. Under the conditions of less rainy days during the blooming period, the temperature is the main factor influencing the reproductive rate, then is the duration of day and the velocity of wind.
