| Abstract | ||||
| The effect of the two host plants Solanum lycopersicum and Solanum nigrum belonging to the family Solanaceae onbiological (survival and duration of developmental stages, fecundity and longevity of females and sex ratio) and demographic parameters (R0, G, rm andλ ) of Tetranychus evansi was studied in the laboratory under controlled conditions: 25°C+ 0.5°C, 75 + 10% RH and 16L: 8D. The rise of intrinsic rate of increase (rm = 0.242 day-1) of the mite population, and time needed to duplicate population numbers (Dt = 2.11 day) on S. nigrum compared to S. lycopersicum (rm= 0.215 day-t, Dt:20.23 day) refers to S. nigrum as a favorable host to T. evansi. | ||||
