四川省赫坎按蚊种团各蚊种卵形态鉴别的可靠性研究

本文论证用蚊卵形态鉴别四川省赫坎按蚊种团各蚊种的可靠性。中华按蚊同嗜人按蚊、筠连接蚊、八代按蚊、贵阳按蚊，凉山按蚊同嗜人按蚊等，用卵形态鉴别比较可靠；其余各蚊种之间卵形态鉴别不完全可靠，必须结合蚊虫生活史中其他阶段的形态进行鉴别;卵甲板定同卵宽、甲板定同浮囊内缘间距离、浮囊内缘至甲板边缘距离同甲板宽等的比值，以及甲板的形状等卵外部形态，在赫坎按蚊种团各蚊种之间的鉴别上占有比较重要的地位。

RELIABILITY OF DISTINGUISHING ANOPHELES SPECIES IN HYRCANUS GROUP BY EGG-FORM

The results showed that: (1 ) It is relatively reliable in distiongishing An. sinensis from An. anthuopopbagus , An. jun lianensis , An. yatsushiroensis , and An. kweiyangensis ; as well as in distiopshing An. liangshanensis from An. anthro pophagus egg-forms. (2) It is relatiVely unreliable among other other species, and it is necessary to conthene withmophological characteristics at other stages of the life cycle. (3) It Plays a very important role in dishopshing the species inAnopheles hyrcanus group by deck shape and outer shape of egg such as ratio of (a) deck-width/egg- width;(b)deck width/width of float inner edges; (c)width Of float inner the to deck-edge/deCk-width.
