Other claims from this paper (7)
- Method / resource Weekly sampling tracked leafminer population trends adequately.
- Method / resource Weekly sampling did not detect first presence of adult and early mine stages adequately.
- Observation One leafminer generation required an average of 476 heat units above base 6.8°C.
- Intervention effect Postponing the first two alfalfa harvests until after egg deposition reduced later leafminer densities.
- Observation The authors warn that postponed harvest may result in substandard crop quality.
- Recommendation Early harvest controls leafminer effectively only if it precedes third instars.
- Association Blotch-mined alfalfa leaflets had 13.8% less crude protein than uninfested leaflets.
