The two-spotted spider mite, Tetranychus-urticae is one of the most damaging polyphagous pests in India. The life history of mated and unmated females of T. urticae was studied on five important host plants namely, Justicia-adhatoda L. (Malabar nut), Wissadula-periplocifolia (L.) Thwaites-(white velvet leaf),-Citrus limon (L.) Osbeck (lemon), Mangifera indica L. (mango) and Syzygium jambolanum (Lam.) DC (water apple), under controlled laboratory conditions at 25 ± 5 °C, 65 ± 5% relative humidity (RH) and photoperiod of 12:12 (L:D). Results revealed no significant variation in life history traits of mated and unmated females of T. urticae on the tested host plants. In contrast only the fecundity and hatchability of mated and unmated females were proved different on different host plants. We, therefore, infer that all the tested host plants provide suitable resource for successful completion of life history of T. urticae. Interestingly, we recorded highest daily and total fecundity rate on M. indica and that suggests preference of two spotted spider mite for mango over other tested host pant. Overall, we can infer that T. urticae can be considered as potential polyphagous pest which could pose serious threat to different crops, fruits and vegetables on which they thrive successfully. © 2020, Institute of Zoology, Slovak Academy of Sciences.
