摘　　要：为明确植保无人机施药防治田间害虫的效果,对比了植保无人机和电动喷雾器分别喷施氯虫苯甲酰胺和茚虫威2种药剂防治玉米草地贪夜蛾的效果。结果表明,2种施药器械喷施2种防治药剂的田间防治效果均无显著性差异。20%氯虫苯甲酰胺悬浮剂(10 mL/667 m^(2))在施药后7 d防效达到最高,植保无人机和电动喷雾器施药防效分别为87.40%和89.99%。保叶率也在施药后7 d达到最高,分别为85.1%和87.1%。30%茚虫威悬浮剂(12 mL/667 m^(2))在施药后2d防效达到最高,植保无人机和电动喷雾器喷施防效分别为84.51%和85.51%,施药后7 d对叶片的保护率分别为75.2%和76.8%。综上所述,氯虫苯甲酰胺的持效性强,茚虫威的速效性好。该研究结果可为使用植保无人机开展大规模统一防治提供重要依据。In order to determine the efficacy of crop protection UAV in controlling field pests,chlorfenacarb and indoxacarb were respectively sprayed with the UAV and electric sprayers to control Spodoptera exigua in maize.The results showed that there was no significant difference in field control effect between two types spraying.The control effect of 10mL/667 m^(2) of 20%chlorfenacarb suspension reached the highest level of control effect at 7 days after application.The control effect of UAV and electric sprayer was 87.40%and 89.99%,respectively,and the protection rate of leaves was also the highest at 7 days after application at 85.1%and 87.1%,respectively.The control effect of 12 mL/667 m^(2) of 30%indoxacarb suspension was the highest at two days after application.The control effect of plant protection UAV and electric sprayer was 84.51%and 85.51%,respectively,and the protection rate of leaves was 75.2%and 76.8%at 7 days after application.Chlorfenacarb had strong long-last control effect,while indoxacarb had good fast-acting effect.The results of this study provide an important basis for using UAV in large-scale integrated pests control.
