A review on reproductive strategies in two spotted spider mite, Tetranychus Urticae Koch 1836 (Acari: Tetranychidae)
This review summarizes some of the important reproductive strategies in phytophagous acarine pest, Tetranychus urticae Koch 1836. It is an economically important agricultural pest with a global distribution which feeds on a wide range of host plant species throughout the world. The rapid developmental rate, high reproductive potential, and arrhenotokous parthenogenesis in T. urticae allows them to achieve damaging population levels very quickly when growth conditions are good, resulting in an equally rapid decline of host plant quality. Moreover, webbing, habitat preference on the underside of leaves, ballooning and high dispersal rate provide additional benefit to the expanding populations of two spotted spider mite, T. urticae.
