Abstract：Pine wilt disease,caused by the pine wood nematode,is one of the most devastating forest diseases globally.The removal of infected dead wood is a core measure in its control,crucial for preventing the spread of the epidemic.This study employed systematically evaluated the operational efficacy of cargo drones(DJI T70 model)in the removal of pine wood nematode-infected trees through field experiments.The results indicate that the drone's average operation time per sortie is kept under 4 minutes and 30 seconds,with an average load capacity of 55.3 kg,enhanced transportation efficiency by 58.8％and reduced costs by 23.5％compared to traditional manual methods.The drone demonstrates significant advantages in complex terrains,with a maximum daily transport capacity of 57 trees,unrestricted by forest road conditions,and capable of precisely reaching remote areas inaccessible to humans.However,drone transportation still faces limitations such as high equipment investment and susceptibility to weather conditions.Based on the findings,this paper proposes a hybrid model combining drone and manual transportation to achieve optimal control effectiveness and economic benefits.
