Other claims from this paper (7)
- Intervention effect Carabid predation immediately reduced aphid density in short alfalfa.
- Intervention effect Carabids reduced aphid parasitism.
- Intervention effect Carabid presence increased aphid population growth rates.
- Intervention effect In tall alfalfa, carabids had no direct impact on aphid density.
- Observation Carabids climbed plants and preyed on parasitoid pupae.
- Mechanism Aphid antipredator behavior protected them from carabids in tall plants.
- Observation The indirect increase in aphid density persisted longer.
