摘要
按生物量来说,在陆地生态系统中土壤动物占其首位。土壤动物的主要作用如粉碎、耕作及土壤的物理和化学性质的变更等常被忽视。众所周知,蚁类是广布的社会性土居昆虫,以其优势的种类和众多的个体同人类发生密切联系。国内有关蚁类的生态学特别是蚁类摄食活动规律的系统研究较少,而国外有关该领域的研究,则日趋活跃。
The present paper deals with a study on the food and assimilate habits of ants in various habitats.In various habitats(farm-land,forest and a resident centre),we found that a number of Formicinae and Myrmicinae in a widespread or general distribution;Ponerinae and Dolichoderinae less than above two subfamilies even no distribution.There are two peaks of feeding time,i.e.8:00-9:00 and 16:00-19:00.The analysis of food shows that all ant groups are omnivorous.The result obtained shows that ant’s feeding in various habitats and microhabitats are affected by microclimate factors,the temperature being the leading factor.On the other hand,the humidity and wind play an indirect role,whereas the light is one of essential conditions.
