Long term observations of the abundance fluctuations of the deer louse-fly Lipoptena cervi were carried out in forest areas of the Leningrad, Novgorod and Pskov provinces in 1988-1995. The registration of the winged individuals was held in the period of the mass flight in August by the number of deer louse-flies attacking a collector man during 1 km of the pathway. The abundance of deer louse-flies was being high everywhere up to 1993, while it decreased by 8-29 times in 1994-1995. The reason of the abundance decrease of deer louse-flies is the abrupt abundance decrease of the main host, the elk Alces alces.
1988 - 1995年期间，在列宁格勒、诺夫哥罗德和普斯科夫省的林区对鹿虱蝇Lipoptena cervi的数量波动进行了长期观测。有翅个体的登记是在8月大规模飞行期间，通过在1公里路径上攻击采集者的鹿虱蝇数量进行的。直到1993年，鹿虱蝇的数量在各地都很高，而在1994 - 1995年期间减少了8 - 29倍。鹿虱蝇数量减少的原因是主要宿主驼鹿Alces alces的数量突然减少。
