Other claims from this paper (7)
- Intervention effect Releasing predatory mites at 1 predator per 24 BGM in 1996 did not significantly reduce pest mites in corn compared with control fields.
- Observation Berlese samples failed to recover released N. californicus or G. occidentalis in experimental corn fields.
- Observation Neoseiulus fallacis was recovered in both release and control fields in 1996 and 1997 but could not be distinguished from native populations.
- Association Neoseiulus fallacis was the most abundant phytoseiid in corn, and its population densities were significantly correlated with BGM populations.
- Association The predator Orius insidiosus was relatively abundant in corn, but its populations were not significantly correlated with BGM populations.
- Observation Several other species of predators suspected to attack BGM were reported in field corn.
- Observation All five phytoseiid species were recovered in corn and in alternate host vegetation.
