晋西北黄土区3种蚂蚁日活动规律研究

Study on Daily Activity Patterns of Three Ant Species in Loess Region of Northwest Shanxi

为探究晋西北黄土区蚂蚁日活动规律及其对温度的响应,以中华红林蚁、日本弓背蚁和中华小家蚁为研究对象,采用样地调查法分析了3种蚂蚁进出洞数量日变化规律,通过一元线性回归方法分析了蚂蚁日活动规律与温度之间的相关性。结果表明:3种蚂蚁均是8:00活动能力最低,随后活动能力显著增强,16:00左右活动能力达到最高峰;日本弓背蚁日活动规律与温度之间存在正相关关系,中华红林蚁和中华小家蚁日活动规律与温度之间不相关。

In order to explore the daily activity patterns of ant species in loess region of northwest Shanxi and their response to temperature,Taking Formica sinensis,Camponotus japonicus and Monomorium chinense as the research objects,the daily changes of the number of ants entering and going out of the hole was analyzed by using the sample survey method.The correlation between the daily activity patterns of ants and temperature was analyzed by unary linear regression.The results showed as follows:the activity capacity of the three ant species was the lowest at 8:00 a.m.,and then the activity capacity increased significantly,reaching the peak at around 16:00;there was a positive correlation between the daily activity patterns of Camponotus japonicus and temperature,but the daily activity patterns of Formica sinensis and Monomorium chinense had no correlation with temperature.
