一、引言鸟类的活动,对森林更新、减少森林害虫的数量等有很大的影响。食虫鸟类取食森林害虫的事实,国内外均有一些报导。鸟类招引是森林害虫生物防治方法之一,我国在解放后才开始进行这方面的研究工作。我们于1958年在沈阳清原湾甸子林场进行了初步试验,1960年开始,在进行食虫鸟类区系调查工作的同时,用木板巢箱在落叶松人工林内对食虫鸟类进行了试验,其间对大山雀的招引试验及工作中的几点体会曾作过报导。现就几年来工作结果报导如下。
I. INTRODUCTION The activities of birds have a great impact on the regeneration of forests and the reduction of the number of forest pests. The fact that insectivorous birds feed on forest pests has some reports both at home and abroad. Bird attraction is one of the biological control methods for forest pests. Only after the liberation did China begin to carry out research work in this field. We conducted a preliminary experiment in Dianzi Forest Farm, Qingyuan, China in 1958. Beginning in 1960, we conducted experiments on insectivorous birds in a larch plantation using a wooden nest box while carrying out an investigation on the flora and fauna of insectivorous birds. In the meantime, it has been reported that the great tits are attracted to some experiments and experiences in their work. The results of work over the past few years are reported below.
