- Association Yellow and clear sticky trap catches were positively correlated.
- Association Trap and beating tray catches tended to have nonsignificant correlations.
- Intervention effect Yellow traps caught many more summer-form psylla than clear traps.
- Intervention effect Yellow traps caught many more fall winter-form psylla than clear traps.
- Intervention effect Before bud break, clear traps caught as many or more psylla than yellow traps.
- Intervention effect As green tissue appeared on pear trees, yellow traps caught far more psylla.
- Association Trap-color catch differences were larger at the higher trap height.
- Observation Spring winter-form sticky trap catches were strongly male biased.
- Observation Early spring beating tray samples showed similar male bias.
- Observation Male bias declined over successive sampling dates.
