Abstract:[Objectives]  To identify the most suitable host plants for the development of Tetranychus urticae and Stethorus punctillum. [Methods]  The developmental duration and fecundity of T. urticae, and the developmental duration, fecundity, hatching rate, pupation rate and eclosion rate of S. punctillum, were measured at a temperature of (25±1)℃ and photoperiod of 14L︰10D, on different host plants. [Results]  There were significant differences in the developmental duration of both species on different plants. The shortest developmental period of T. urticae was on peanut (9.82 d) and maximum fecundity of this species was recorded on peanuts and cowpeas. The developmental period of S. punctillum was shortest on peanut and cowpea (no significant difference), and highest on corn, peppers and eggplant. Fecundity of S. punctillum on the different banker plants was, peanut (112.60), cowpea (103.80), corn (85.20), pepper (68.20) and eggplant (53.40) and its adult eclosion rate on different banker plants was, peanut (80.11%), cowpea (70.26%), corn (66.66%), pepper (9.70%) and eggplant (29.81%). [Conclusion]  Of the banker plants tested, peanut was the most suitable host for Tetranychus urticae and Stethorus punctillum.
