Other claims from this paper (17)
- Association Downy mildew spread may increase Phytoseiidae abundance in European vineyards.
- Association Downy mildew spread may increase Tydeidae abundance in European vineyards.
- Association Amblyseius andersoni responded clearly to downy mildew spread.
- Association Typhlodromus pyri responded to downy mildew at lower magnitude than Amblyseius andersoni.
- Association Kampimodromus aberrans responded to downy mildew at lower magnitude than Amblyseius andersoni.
- Mechanism Downy mildew benefits phytoseiid survival, development and reproduction and thereby their population dynamics.
- Mechanism Downy mildew benefits tydeid survival, development and reproduction and thereby their population dynamics.
- Association Downy mildew effects were more relevant for A. andersoni than T. pyri.
- Observation T. pyri controls phytophagous mites more effectively than A. andersoni in vineyards.
- Association Powdery mildew was a less pronounced food source than downy mildew for A. andersoni.
- Association Powdery mildew was a less pronounced food source than downy mildew for T. pyri.
- Mechanism Persistence of generalist predatory mites in perennial ecosystems contributes to biological control of phytophagous mites.
- Mechanism Feeding on various foods may improve predator persistence in vineyards without prey.
- Observation Pollen is probably the most important food source in spring and early summer.
- Observation Mildews increase in importance as food in late summer.
- Association Pesticide use largely affects predatory mite persistence.
- Association Downy mildew can enhance predatory mite population recovery after pesticide applications.
