Other claims from this paper (16)
- Observation Jassid incidence ranged from 2.4 to 7.5 nymphs per three leaves.
- Observation Aphid infestation ranged from 15.0 to 38.9 percent.
- Observation Coccinellid activity ranged from 0.1 to 0.4 per plant.
- Observation Chrysopid activity ranged from 0.52 to 1.87 per plant.
- Observation Chrysopids had a more persistent population than coccinellids.
- Association The predator populations were positively but nonsignificantly associated (r=0.058).
- Association Jassid incidence was higher on hybrids than varieties.
- Association Aphid incidence was higher on hybrids than varieties.
- Association Predator incidence was higher on hybrids than varieties.
- Association Long-term soil fertility changes had no direct influence on predators.
- Association Sole cropping had 1.83 chrysopids per plant, higher than soybean intercropping.
- Association Sole cropping had 0.99 coccinellids per plant, higher than soybean intercropping.
- Association Aphid infestation was 19.2% in sole cotton versus 24.2% with soybean intercropping.
- Observation Coccinellids occurred discontinuously under protected and unprotected conditions.
- Observation Chrysopids continued to occur from August through November.
- Observation Both predators recolonized after insecticidal sprays.
