通过形态特征和行为习性的比较,提出海南岛的微小按蚊可分为两个类型即微小按蚊A型和微小按蚊B型。前者成虫翅纵脉4第1分枝除基、末端外有1～2个淡斑,极少一致暗色;食窦甲一个齿、前面观,丝状物短其末端分叉;幼虫头部颏齿数7极少9:嗜人血为主;对DDT极为敏感。后者成虫翅纵脉4第1分枝除基、末端外一致暗色;食窦甲一个齿、前面观,丝状物细长无繸缘或侧棘其末端不分叉:幼虫头部颏齿数9或11;趋牛血为主;非家栖、对DDT有明显兴奋和逃避行为,是一种近野栖种。
Through the comparison of morphological characteristics and behavioral habits, it is proposed that Anopheles minimus in Hainan Island can be divided into two types, ie, Anopheles minutiae type A and B type. The former adult wing longitudinal veins 4 first branch in addition to the base, there are 1 to 2 outside the end of the spot, rarely consistent dark color; food sinuatus a tooth, the front view of the filament short end of the fork; larvae head chin Very few teeth 9: blood-based human-induced; very sensitive to DDT. The latter wing of the adult longitudinal veins 4 first branch in addition to the base, the same end of the outer dark; Sinus serratus a tooth, the front view of the filament slender without margin or lateral spine its end does not bifurcate: larvae head chin number 9 or 11; bullock blood dominated; non-domestic habitat DDT obvious excitement and evasion behavior, is a near-field species.
