Abstract
The two spotted spider mite Tetranychus urticae Koch (Acari:
Tetranychidae), is well known as a phytophagous mite causing considerable
damages in major crops even in hot environments as indoor agricultural ecosystem.
In order to clarify to what extent T. urticae could withstands high
temperature, we experimentally investigated the life history of T. urticae
under five different degrees of temperature (20℃, 25℃, 30℃, 35℃ and 40℃) under
laboratory conditions. The study showed that T. urticae rapidly adapt to
the increase in temperature, its incubation period, life cycle, generation
period and reproduction all affected positively with the increase of
temperature as showing high significant effect. Also, all measured life table
parameters were indicated that the increase of temperature works to benefits of
T. urticae female, as the generation doubling time decrease to almost
only half day at the highest tested temperature, which eventually leads to
shifting the threat from T. urticae to a higher latitude.
