ミカンキイロアザミウマFrankliniella occidentalis によるキンカン幼果の加害

抄録

Damage caused by western flower thrips Frankliniella occidentalis occurred on young fruits of kumquat Fortunella crassifolia in a greenhouse. Many white points observed on the fruits seemed to be caused by oviposition. By releasing the adults to young fruits, we demonstrated that the damage was caused by females infesting from 1 – 3 weeks after blooming.
