摘要： 1984～1985年在四川西昌泸山德昌松毛虫严重为害的云南松林区,按每隔40～50米距离,挂放人工巢箱一个。检查400个巢箱的结果:益鸟招引率达70.2～80.7％,招引的鸟种主要有山麻雀、大山雀,绿背山雀和戴胜。挂箱后林内食虫鸟数较对照区增加64.3～75.0％,松毛虫密度下降83.3～96.4％。

Abstract: Experiments were conducted in the pine (Pinus yunnanensis) forests infested by Dendrolimus punctatus tehchangensis in Lushan, Sichuan Province during 1984-1.985. Artificial bird nests were placed on the trees at 40-50 meters apart to attract birds, and were checked every year. The results showed that 70.2-80.7% of the nests were used by naturally occurring birds, mainly Passer ratilans, Parus major, Parus monticolus yunnanensis, and Upupa epops saturata. A 64.3-75.0% increase in the number of birds and 83.3-94.45% decrease in the pine caterpillar populations were found in the forest compared with those in the check forest where no artificial nest was provided.
