| 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. |
