Summary
The Asian longhorned beetle can fly up to 8.5 miles, with fed adults over 5 days old showing the best flight performance. This data aids in refining eradication protocols for this invasive woodborer.
Area of Science:
- Entomology
- Invasive Species Biology
- Pest Management
Background:
- The Asian longhorned beetle (Anoplophora glabripennis) is a destructive invasive woodborer threatening North American landscapes.
- Eradication efforts focus on host removal and treatment, but require better understanding of beetle dispersal.
Purpose of the Study:
- To assess the flight capabilities of the Asian longhorned beetle under varying conditions.
- To inform enhanced eradication strategies for this quarantine pest.
Main Methods:
- Computerized flight mills were used to track the flight performance of 162 adult Asian longhorned beetles over 24 hours.
- Variables included beetle age, mating status, nutritional status, sex, and body size.
Main Results:
- Adult beetles flew an average of 2,272 m, with a maximum recorded distance of 13,667 m (8.5 miles).
- Adults over 5 days old that had fed exhibited significantly greater flight performance.
- Mating status, sex, and body size had minimal impact on flight distance.
Conclusions:
- Flight performance is primarily influenced by adult age and nutrition.
- Findings will refine quarantine zone boundaries and risk assessments for Asian longhorned beetle infestations.
