Fig. 1.

Volume (in mm³) of thrips larvae versus age (in days), when developing on clean plants (circles uninfected larvae; n = 75) and plants that were mechanically inoculated with Tomato spotted wilt virus (TSWV) (triangles infected larvae; n = 65). Points show average values ± SEM. Curves were obtained by fitting Eq. 1 to the data. For uninfected thrips larvae, the estimated growth rate (r) is 0.384 ± 0.019, the maximum volume (S _m) is 0.0455 ± 0.0031; for infected thrips r = 0.662 ± 0.025 and S _m = 0.0493 ± 0.0012.
