中文摘要 | 印度棗葉蟬〔 Quadria pakistanica (Ashmead) 〕為印度棗之主要害蟲,能刺吸 葉液並分泌蜜露誘發煤病, 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 cm �插^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 �� =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 %亞減寧乳劑防治效果較佳。 |
英文摘要 | 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 �� =0.9564**). 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. Nice 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. |
