Other claims from this paper (11)
- Observation densities were higher in the upper canopy than the lower canopy
- Observation The percentage of females having mature eggs was lowest in late May, and highest in June and September
- Observation Sex ratios were highly variable among sampling dates and among sampling methods
- Observation Sex ratios in bags tended to be more female‐biased in the lower canopy than in the upper canopy
- Observation Sticky trap counts were significantly male biased
- Observation Mean sex ratios differed significantly between bag and sticky trap samples at both heights
- Observation did not differ significantly between tray and bag samples at either height
- Observation sticky trap catch of males was larger than catch of females
- Observation Bag counts (psyllids per leaflet) strongly increased with tray count
- Method / resource this method is extremely time consuming
- Method / resource beat trays can be used to estimate absolute densities
