Tabla de vida y parámetros poblacionales fundamentales de Tetranychus urticae koch (Acari: tetranychidae) sobre rosa Sp. en condiciones de laboratorio
The two spotted spider mite, tetrenychus urticae Koch is one of the most widely dlstributed mites in the world and one of the maln causes of losses in commercial greenhouses in Bogota. Using the leaf dlsc technique some basic biologlcal data were studied under laboratory conditions with a temperature of 23 ±2°C and a relative humidlly of 85 ± 5%. Life cycle wasdetermined uslng rose leaves as host plant. Ovlposition time for females was 35 days with an average of 3.52 eggs per female per day. Net reproductlve rate (Ro), mean length of a generation(T), Intrinsic rate of natural increase (r..,.,,) finite rate of reproduction ('A) and stable age distribution were calculated.
