无人机喷雾技术防治刚竹毒蛾幼虫效果评价

为明确无人机喷雾与人工喷雾在防治效果和成本上的差异，揭示植保无人机喷雾施药技术的优点，在福建邵武发生刚竹毒蛾为害的毛竹林建立试验区，选用5种不同作用机制的生物农药，开展无人机喷雾和人工地面喷雾施药技术的防治对比试验。结果表明：无人机喷雾对刚竹毒蛾幼虫的防效显著好于人工喷雾，且在防治工效、人工费用和防治成本上均优于人工喷雾，表明植保无人机喷雾是一种便捷高效且节时、省力、降费的施药技术，可推广应用于林业有害生物的防治。

Evaluation of the Effect of UAV Spray Technology on Pantana phyllostachysae Larvae Control

In order to find out the difference in control effect and cost between UAV spray and manual spray, and reveal the advantages of spraying and application technology by UAV for plant protection, a test area is established in a Phyllostachys edulis forest haunted by Pantana phyllostachysae in Shaowu County, Fujian Province, and 5 types of biological pesticides with different action mechanism are selected to carry out the contrast test between UAV spray technology and artificial ground spray technology. The results show that the control effect of UAV spray on the larvae of P. phyllostachysae is significantly better than that of manual spray, and UAV spray is also better than manual spray in control efficiency, labor costs and control costs. This indicates that UAV spray for plant protection is a convenient, efficient, time-saving and cost-saving spray technique, which could be widely used in forest pest control.
