Ecological Studies of Asiatic Citrus Psyllid (Diaphorina citri K.) with Special Reference to Its Spatial Distribution

Abstract

Experiments on spatial distribution of asiatic citrus psyllid (Diaphorina citri Kuwayama) were conducted at Taiwan Agricultural Research Institute from the winter of 1979 to the summer of 1981. Forty 4th or 5th instar nymphs of asiatic citrus psyllids were introduced on 240 pot-raised citrus saplings (Citrus reticulata var. Suenket) in greenhouse. 本試驗於民國68年冬季至70年夏季在臺灣省農業試驗所溫室及田間進行，將40隻第4或第5齡木蝨（Diaphorina citri Kuwayama）幼蟲放飼於溫室內240株盆栽之酸橘（Citrus reticulata var. Suenket）苗上，任其繁衍，所得幼蟲最高密度為每株57.1隻。
