目的了解吉林省公主岭市白蚁种类及危害。方法对吉林省公主岭市东三街民安委房屋白蚁危害现场进行了实地调查。结果危害白蚁种类为栖北散白蚁。民安委白蚁发生率按户数为0.7%。房屋的地板、木窗台、门框、壁板等受到白蚁危害,木屋架未受白蚁危害,主要危害房屋下部木结构。群体组成有翅成虫、工蚁、兵蚁和若蚁占总数的比例分别为0.08%、66.59%、0.57%和32.76%。白蚁危害至少已10年以上,已连续7~8年出现有翅成虫分飞,分飞时间从每年的5月起,分数次分飞。结论栖北散白蚁为公主岭市自然分布的种类,只是由于分布极为稀疏,因此较难发现和采集,且扩散和危害的速率均十分缓慢。气候变暖和城市化成为公主岭市房屋白蚁危害发展的重要成因。在日均温为更低的区域(≥5.93℃),栖北散白蚁依然可以分布。我国白蚁危害的北界正在向北移动。
