This study aims to Potential of Refugia Plants as Microhabitat for Predator Sycanus sp. This research was conducted in Faculty of Agriculture, University Sumatera Utara, Medan. This research was conducted from February 2023 to June 2023. This study used a Non-Factorial Complete Randomized Design (RAL) with four treatments and five repeats, each treatment as follows: control (without refugia plants), (T. subulata), (A. leptosus) and (C. cobanensis). The results showed that: S. annulicornis predators are more often present on refugia plants in the morning and evening, The highest duration of time for the presence of S. annulicornis predators is found in (T. subulata) followed by ( A. leptosus) and (C. cobasinensis), Fecundity ability of S. annulicornis predators given (T. subulata) followed by (A. leptosus) and (C. cobasinensis).
