Abstract EN
Some life table statistics of the two spotted spider mite, T.
urticae was evaluated under constant temperatures of 25º and 30ºC.
Development and reproductive potential of the mite was also studied.
The development time of the immature stages was 11.85±0.31 days at 25º and 8.84±0.24 days at 30ºC.
The calculated time needed for the development decreased with the increase in temperature.
The longest period was recorded at 25ºC but the shortest was revealed at 30ºC.
The calculated developmental threshold (t0) of the whole immature stages was estimated as 10.32ºC.
The thermal units needed for the development from egg to adult were 173.97 day-degrees.
The generation time (GT) was 18.31 and 12.19 days, reproductive potential (R0) was 51.47 and 28.50 individuals / female, population doubling time (DT) was 3.22 and 2.52 days, intrinsic (rm) was 0.2152 and 0.2748 and finite rate of increase (λ) was 1.2401 and 1.3163 at 25 and 30ºC, respectively.
Based on the obtained data, temperature of 25°C was the most suitable temperature for the development and reproduction of spider mite.
