A Keystone Ant Species Provides Robust Biological Control of the Coffee Berry Borer Under Varying Pest Densities

Fig 5

Functional response curve.

Shows the mean number of coffee berry borer (CBB) individuals attacked by Azteca sericeasur (± SE) across CBB density treatments (10, 20, 40, and 80 individuals). A simple linear regression model, shown by the line, suggests a Type I functional response (R² = .9948, F = 761.4, p < .001).
