Other claims from this paper (6)
- Intervention effect Released parasitoids parasitized an estimated 57.4% of placed corn borer egg masses.
- Intervention effect Parasitoid releases reduced corn borer larvae per ear by 97.4%.
- Intervention effect Parasitoid releases reduced corn borer larvae per stalk by 94.3%.
- Intervention effect Ear damage was suppressed to acceptable cut-corn processing standards.
- Observation Larval mortality was apparently density independent.
- Mechanism Density-dependent larval loss would not compensate for egg parasitism by T. nubilale.
