文摘

Conservation biological control needs natural enemy metrics that predict pest control. Natural enemy diversity metrics and predator-prey ratios were tested as possibly useful metrics. Predator-prey ratio and percent parasitism are correlated with current biological control. Natural enemy units showed promise, but density dependence confounds the results. No natural enemy metrics were found to suitably predict future biological control potential.
