Effects of sampling designs and mining patterns on Ophiomyia maura larval and pupal parasitism*.

*Parasitism was treated as a dummy variable; it took 1 if a leafminer was parasitized, or 0 otherwise.†Sampling group was a dummy variable that took 1 for leafminers collected from the inner group, or 0 for leafminers collected from the outer group.‡Standardized coefficients were calculated to compare the relative contribution of each independent variable.
