灰喜鹊南移驯养灭虫试验

Study on Experiments in Moving and Taming the Azurewinged Migpie in the South to Destroy Insects

鸟类在消灭农林害虫和维护生态平衡等方面有着特殊的贡献,以鸟治虫是综合防治的重要措施之一。为了探索一条南方有效的生物防治途径,我们制订了具体试验方案,于1984年7月从安徽省定远县泉坞山林场引进40只野生的灰喜鹊幼鸟(除损耗外,供1985年试验29只;供1986年试验22只),在白云山开展了灰喜鹊的饲养、繁殖、驯化和放鸟治虫方面的试验研究,取得了较好的生态效益、社会效益和经济效益。

Forty birds of Azure-winged Migpie (Cyanopica cyana swinhoe) were introduced into Guangzhou from Dingyuan,Anhui Prov.in July, 1984.After three years'rearing of these birds,excepting 18 ones died, achievements have been won in moving the species from north to south (from 32.30° N.to 23.18° N.) and making it reproduce free in bird-room,as well as in taming it to control the damages done by insects to forests. According to our observation and analysis on inseet foods of these birds and their successors,several tens of species of insect have been eaten and more than 60 thausand of Bamboo Locusts can be eaten by each bird per year,which shows the important signification of this species of bird in maintaining ecological balance and produ- tion of agriculture and foresty.Thus the successful experience proves that the Azure-winged Migpie can adopt well to the environment of Guangzhou and will benefic the people of the place in economy and ecology,as well as develop a new way for preventing and treating biolog ically harmful insects.
