Table 1 Estimates of variance components for population parameters (i.e., the intrinsic rate of increase r, the mean generation times T, the finite rate of increase λ and the net reproductive rate R0) of Sitobion avenae clones showing the main effects of Regiella insecticola and clone (i.e., ‘Linyi’ and ‘Neixiang’) nested in the Regiella insecticola.
