Leafhopper and Predator Population Response to Irrigation and Birdwatcher (BW) Treatments in Vineyards #2068558 (License: Personal Use)

This bar chart displays estimated ln(x+1) means of leafhopper (green) and predator (red) populations under four experimental conditions: control (no irrigation or BW), irrigated vineyard (no BW), BW present but not in the same row as the trap, and BW present in the same row as the trap. Leafhopper counts increase progressively from ~1.9 in the control to ~2.95 when BW is co-located with the trap, whereas predator counts stay near zero except for a slight rise (~0.2) when BW is in the plot but not co-located. The data suggests BW presence correlates strongly with higher leafhopper density, with negligible impact on predators.

Used in agricultural entomology or viticulture research articles, extension reports, or sustainability webpages discussing integrated pest management; targets researchers, growers, and agronomists seeking evidence on non-chemical pest dynamics and ecological interactions in vineyards.
