Current trap counts through August 13th, 2019
- AT A GLANCE:
- Last week, 26% of locations had 3+ moths per day.
- Last year, trap catches didn’t reach 3 moths per day until mid-October.
- True armyworm can have 3-5 generations per year.
- There may be higher armyworm pressure than there was last year. Scouting is recommended.
- Sites 8 & 15 have very high trap counts; 8-9 moths per day.– SEE GRAPH BELOW –
Numbers indicate adult true armyworm moths (Mythimna unipuncta) detected from pheromone traps placed throughout the region. Remember: larvae are the damaging phase and usually appear about 25 days after a spike in adult activity. However, this estimate can vary widely and depends on many factors (temperature, migration, natural enemies, pest management strategies, etc.). In fact, investigating the relationship between trap catches and damage in the field is a main objective of this research.For questions or more information, contact us (click here)
