| 中文摘要: |
| 2006-2009年调查了葡萄斑叶蝉田间种群消长动态，并对防治药剂进行了筛选。结果表明葡萄斑叶蝉在贺兰山东麓一年3代，从5月上旬即在葡萄上为害，一直持续到10月。成虫数量全年共出现3个高峰期，分别为5月中旬、7月上中旬和9月下旬-10月上旬。若虫高峰期分别为5月下旬-6月上旬、7月中下旬和8月下旬-9月中旬。5月下旬-6月上中旬是葡萄斑叶蝉防治的最佳时期。70%吡虫啉水分散粒剂、25%噻虫嗪水分散粒剂、40%毒死蜱乳油对葡萄斑叶蝉既具有较好的速效性，又有很好的持效性，药后1～14 d药效均在95%以上； 25%噻嗪酮可湿性粉剂药后1 d药效较低， 7 d后药效开始上升，药后14 d达100%。 |
| 英文摘要: |
| Population dynamics of Erythroneura apicalis was investigated, and insecticides for control of this pest insect were evaluated during 2006-2009. The results showed that the grape leafhoppers had 3 generations per year. They damaged grapes from May to October. The leafhopper adult had 3 peaks. The first peak was in the middle of May, the second peak in early July and the third after late September. The leafhopper nymphs had 3 peaks too. The first peak was from late May to early June, the second peak between middle and late July, and the third from late August to middle September. The optimal period for control of leafhoppers is from late May to middle of June. 70% imidacloprid WP, 25% thiamethoxam WP and 40% chlorpyrifos EC could effectively and quickly control leafhoppers. The control effect rate was over 95% from 1 d to 14 d. The control effect of 25% buprofezin WP was lower in 1 d, but it began to rise after 7 d. The control effect rate in 14 d was 100%. |
