Detection and Location of Dead Trees with Pine Wilt Disease Based on Deep Learning and UAV Remote Sensing

AgriEngineering, 2020
Pine wilt disease causes huge economic losses to pine wood forestry because of its destructiveness and rapid spread. This paper proposes a detection and location method of pine wood nematode disease at a large scale adopting UAV (Unmanned Aerial Vehicle)

Detection of the Monitoring Window for Pine Wilt Disease Using Multi-Temporal UAV-Based Multispectral Imagery and Machine Learning Algorithms

Remote Sensing, 2023
Pine wilt disease (PWD) has caused huge economic and environmental losses since it invaded China. Although early monitoring is an effective way to control this hazard, the monitoring window for the early stage is hard to identify, and varies in different

Gene sdaB Is Involved in the Nematocidal Activity of Enterobacter ludwigii AA4 Against the Pine Wood Nematode Bursaphelenchus xylophilus

Frontiers in Microbiology, 2022
Bursaphelenchus xylophilus, a plant parasitic nematode, is the causal agent of pine wilt, a devastating forest tree disease. Essentially, no efficient methods for controlling B. xylophilus and pine wilt disease have yet been developed.

Analysis of the Mathematical Model for the Spread of Pine Wilt Disease

Journal of Applied Mathematics, 2013
This paper formulates and analyzes a pine wilt disease model. Mathematical analyses of the model with regard to invariance of nonnegativity, boundedness of the solutions, existence of nonnegative equilibria, permanence, and global stability are presented.

Monochamus galloprovincialis distribution in Aleppo pine forests in Tunisia

Turkish Journal of Forestry, 2016
The pine wilt disease, caused by the pine wood nematode (PWN) Bursaphelenchus xylophilus, was detected in Europe in 1999 in Portugal and the longhorn beetle Monochamus galloprovincialis reported as the only vector since 2001.

Establishment of embryogenic Pinus thunbergii Parl. suspension cultures: growth parameters, dynamic analysis, and plant regenerative capacities

BMC Plant Biology
Background Pinus thunbergii is an economically important conifer species that plays a fundamental role in forest ecosystems. However, the population has declined dramatically in recent years as a result of the pine wilt disease outbreak. Thus, developing
