| 为了解植保无人机低空低容量喷雾对枣园主要害虫的防治效果，在植保无人机喷施农药后，调查了对截形叶螨、枣瘿蚊的防治效果，结果发现：在供试飞行条件下，药后5 d 25%环氧虫啶（用药量为300 g/hm2）、70%吡虫啉（用药量为150 g/hm2）对枣瘿蚊的防治效果最高，分别为87.73%和89.74%，两处理之间无显著差异，均与22%噻虫·高氯氟（用药量为375 g/hm2）处理有显著性差异；药后13 d 30%乙唑螨腈（用药量为262.5 g/hm2）和45%螺虫·乙螨唑（用药量为105 g/hm2）对不同方位枣树截形叶螨的防治效果在90%以上，平均防治效果分别为98.64%和93.95%，两处理之间无显著差异，与1.8%阿维菌素+20%双甲脒（用药量为345 g/hm2+525 g/hm2）有显著性差异；各处理雾滴覆盖密度之间均无显著性差异。因此，在生产中用植保无人机喷施25%环氧虫啶、70%吡虫啉、30%乙唑螨腈、45%螺虫·乙螨唑对枣园枣瘿蚊和截形叶螨能起到良好的防控效果。 |

| In order to clear the control effects of unmanned aerial vehicle (UAV) spraying against the main pests in jujube orchard, the control effects were investigated. The results showed that under the condition of selected operation parameters, the control effects of 25% cycloxaprid (300 g/hm^2) and 70% imidacloprid (150 g/hm^2) against Dasineura datifolia were the highest, with an average of 87.73% and 89.74% respectively on 5 days after application, which was significantly higher than that of 22% thiamethoxam·lambda-cyhalothrin, there was no significant difference between the two treatments. The control effects of 30% SYP-9625 (262.2 g/hm^2) and 45% spirotetramat·etoxazole (105 g/hm^2) against Tetranychus truncatus were above 90% at different parts of jujube tree, with an average of 98.64% and 93.95% respectively on 13 days after application, which was significantly higher than that of 1.8% abamectin+20% amitraz (345 g/hm^2+525 g/hm^2), there was no significant difference between the two treatments. There was no significant difference in the droplet density. So used UAV spraying 25% cycloxaprid, 70% imidacloprid, 30% SYP-9625 and 45% spirotetramat·etoxazole against Contarinia datifolia and Tetranychus truncatus could achieve good control effects in production. |
