摘要

印度棗葉蟬[Quadria pakistanica (Ashmead)]為印度棗之主要害蟲，能刺吸葉液並分祕蜜露誘發煤病，影響植株發育至鉅。於本省南部印度棗產地之為害葉率介於2.81-50.50%，平均20.07%。其族群密度自9月開始增加，11月達最高峰，12月開始下降，利用黃色粘片(15×21.5 平方公分)誘集其成蟲數(Y)與葉片若蟲數(X)之直線關係式為Y=-19.23+0.59X，r^2=0.9564。於大社地區調查結果本蟲於9~11月受昆蟲寄生真菌(vertici llium lecaric)感染最多，罹病率為1.12-36.47%，平均為4.24%。田間藥劑防治篩選結果，以2.8%賽洛寧乳劑、85%加保利可濕性粉劑、90%納乃得可濕性粉劑及3%亞滅寧乳劑防治效果較佳。

Indian-jujube leafhopper damaging leaf and inducing sootymold by excreting sticky honeydew is a destructive insect pest on Indian-jujube in southern Taiwan. The leaves were usually infested by 2.81-50.50% with 20.07% in average. Its population built up rapidly in September, with a peak in November and declined gradually in December.
The number of nymphs on the leaf of plant(X) and adults(Y) caught by yellow trap could be expressed as Y=-19.23+0.59X, (r^2=0.9564(superscript **).
It was highly infected by Verticillium lecaric from September to November ranging between 1.12-36.47% and with 4.24% in average in Ta-sou area.
Nine insecticides were tested in this experiment for its control. Results indicated that 2.8% Cyhalothrin EC, 85% Carbaryl WP, 90% Methomyl WP and 3% Fastac EC showed better control.
