Other claims from this paper (10)
- Association Wireworms assembled in increasing numbers at wheat rows as planting density increased.
- Observation No wireworm damage to seedlings was apparent in treated wheat plots at all planting densities.
- Association Dead wireworm counts in treated plots rose linearly with seeding density.
- Observation The dead-wireworm line met the modeled 100% mortality point at 0.95 seeds/cm on 11 June.
- Observation The dead-wireworm line met the modeled 100% mortality point at 1.14 seeds/cm on 18 June 1996.
- Observation Untreated wheat at every planting density had severe wireworm damage.
- Observation Untreated wheat at every planting density had a significantly reduced stand.
- Association Fewer wireworms assembled at surviving untreated wheat than in treated wheat plots.
- Association Wireworm populations at surviving untreated wheat increased with seeding density but did not follow the asymptotic model.
- Recommendation The authors suggest that treated wheat trap crops can assemble and kill many A. obscurus in fallow fields over 19 days at the specified row spacing and seeding density.
