燕子是候鸟,每年五月中、下旬来到东北,秋季十月南迁。家燕Hirundo rustica南可到印度、南洋群岛、以至澳洲越冬,间有少数留居我国东南部。金腰燕Hirundo daurica常与家燕同时南北往返迁徙。因此,燕子体外的寄生虫有超越地区种类的可能性,值得注意。国内对于燕窝内之寄生虫调查不多,兰氏(1982年)报告由浙江开化燕窝中采到青原丽蝇Protocalliphora azurea及赵氏角叶蚤Ceratophyllus chaoi皆为该省之新纪录。 Swallows are migratory birds, each in mid-May, late came to the northeast, autumn October south. Barn swallow Hirundo rustica south to India, the South Pacific Islands, as well as Australia overwintering, a few still living in southeastern China. Hirundo daurica Golden Retriever Yan and Yan often move back and forth north-south. Therefore, it is noteworthy that the parasites in vitro of swallows have the possibility to transcend the regional species. Domestic investigation of parasites in the bird’s nest is not much, Lan (1982) reported from the Kaihua bird’s nest in Zhejiang Province to Qingyuan Blowfly Protocalliphora azurea and Ceratophyllus chaoi’s leafhopper Ceratophyllus chaoi are the new record.
