Western Bean Cutworm Trapping in the Northeast
Something went wrong. Please try again later...
Objectives
- Map the geographic distribution and population dynamics of western bean cutworm (WBC).
- Identify "hot spots" and entry corridors to explore and educate growers on product performance in these regions.
Study Description
| Geography: | Penn., N.Y., Vt. |
| Locations: | 20 Pioneer traps |
| 70 Extension traps | |
| Materials: | Green bucket traps (dry) |
| Scentry® Pheromone LWC1131 | |
| Hercon® Vaportape™ II | |
| Duration: | June 18 - August 27, 2013 |
| Reporting: | Once per week |
Results
- WBC populations are widespread and continue to increase annually in New York.
- In general, higher WBC counts have been observed in northern and western New York counties.
- Peak flight was observed during the last week of July.
- Pristine condition of most moths captured indicate WBC populations are becoming locally established.
- To date, there have been no reports from NY/NE of economic damage caused by WBC to corn (sweet or field) or dry beans.
- Pheromone trap monitoring for WBC is planned for 2014.
Additional In-Season Monitoring
2013 data are based on average of all comparisons made in 90 locations through August 27, 2013. Multi-year and multi-location is a better predictor of future performance. Do not use these or any other data from a limited number of trials as a significant factor in product selection. Product responses are variable and subject to a variety of environmental, disease, and pest pressures. Individual results may vary. All products are trademarks of their manufacturers.
