稻茎毛眼水蝇Hydrellia sasakii Yuasa et Isitani,1939(双翅目:水蝇科)的鉴别

ON THE IDENTIFICATION OF HYDRELLIA SASAKII YUASA ET ISITANI FROM CHINA (DIPTERA:EPHYDRIDAE)

在我国南方,先后在广西、湖南发现菲岛毛眼水蝇 Hydrellia philippina Ferino,1968。它为害水稻,受到人们重视。在我国湖北省当阳、荆州、安徽省合肥及福建三明[三明标本前曾误认为菲岛毛眼水蝇(范滋德等,1983)]。近年来发现一种与菲岛毛眼水蝇极为近似的种类,姚康教授生前曾鉴定为稻茎毛眼水蝇 Hydrellia sasakii Yuasa et Isitani,1939。为了确认无误,作者之一(范)曾以雄性尾器图函恳日本农业环境技术研究所昆虫分类研究室福原楢男博士协助解决,承告据目前知识看来以认作 H.sasakii 为好(福原,1984,

This paper gives a report on the identification of Hydrellia sasakii Yuasa et Isitani,1939,which is a pest of rice recently recorded from Anhui,Hubei and Fujian provinces,China.It was misidentified as H.philippina(Fan et Zhou,1983,nec Ferino,1968,Wuyi Sci.Jour., 3:143-144,5 figs)which was based on specimens collected from Shah- ruing of Fujian.For the elucidation of these two species,the differences of their terminalia are compared as shown in table l.The male term- inalia of the present species are illustrated as shown in figures 1-4. The authors are most grateful to Dr.Fukuhara of the Institute of Agricultural Environment and Technigue Research,Tsukuba,Japan,who offered them with valuable information on the identification of the pres- ent species.
