Sadao Takagi

Sadao Takagi (高木 貞夫, Takagi Sadao, born 1932, Toyama Prefecture, Japan) is a Japanese entomologist who has specialised in the scale insects (Coccoidea), particularly the amoured scale insects of the Diaspididae.

Takagi studied at Hokkaido University, where he received his bachelor's degree, his masters and his doctorate in agriculture. He specialized in studying the amoured scale insects. After graduation he remained at Hokkaido University and taught, first as an Associate Professor and then as a full Professor.

Takagi's morphological insights have been proven correct by subsequent molecular analysis. Among other things, he demonstrated the polyphyletic nature of the now-obsolete Rugaspidiotini using morphology.

Takagi retired from teaching in 1996, but continues to publish.
