Yi Wang, Wei Huang, Evan Siemann, Jianwen Zou, Gregory S. Wheeler, Juli Carrillo, and Jianqing Ding. 2011. Lower resistance and higher tolerance of host plants: biological control agents reach high densities but exert weak control. Ecological Applications 21:729–738.

Appendix D (TABLE D1). Slope and intercept comparisons in the weevil experiment: differences in slopes and intercepts between treatments (I-L: invasive populations in light conditions, I-S: invasive populations in shade conditions, N-L: native populations in light conditions, N-S: native populations in shade conditions). A significant P value indicates that intercepts or slopes differed between that pair of treatments.
