Study Notes
Detection Technologies in Pest Management
- Aerial Color-Infrared (CIR) photography and multi-spectral videography are effective for identifying insect infestations in citrus orchards and cotton fields.
- Various types of entomological radars have been developed, including Airborne Entomological Radar (AER), Scanning Entomological Radar (SER), Tracking Entomological Radar (TER), and Vertical-Looking Radar (VLR).
- SER and VLR are commonly used to study the migration behavior of high-altitude migratory insects.
Remote Sensing Applications
- Multi-spectral remote sensing (MRS) is utilized to detect early spider mite infestations in large-scale cotton fields, focusing on canopy changes over time.
- Ground-based hyperspectral remote sensing can provide important pest management data, including assessing leafhopper damage through spectral analysis.
Hyperspectral and Radar Technologies
- A hyperspectral radiometer operating within 350–2500 nm helps estimate chlorophyll and relative water content in plants affected by pests.
- A multi-frequency radar utilized in East China recorded significant differences in insect populations, enabling better pest identification.
Innovations in Insect Tracking
- Recent developments in harmonic radar technology enhance the tracking of insects, exemplified by studies on Vespa velutina, which can monitor insect flight up to 500 m in altitude.
- Radar technology offers advantages over traditional sampling methods, such as the ability to detect a wide range of insects at various altitudes and large sampling volumes.
Monitoring and Impacts of Locusts
- Monitoring technologies have been used for forecasting locust species migration; a swarm can cover 1200 km², potentially affecting millions of people.
- Significant crop damage, particularly during locust migration, has been documented, highlighting the need for advanced monitoring systems.
Conclusion on Remote Sensing Advances
- Advances in remote sensing technology are transforming approaches in agricultural pest and plant disease management.
- Enhanced data interpretation and analysis through technology support numerous research fields, paving the way for broader applications in agricultural science.
