Rice Black Bug (Scotionophara coarctata) is one of important rice pests that attack all growth stages of rice. This research was aimed to the most determine resistance of some varieties of black bug (S. coarctata). This research was aimed to determine resistance of several rice varieties against rice black bug (S. coarctata). This research was conducted in the Laboratory of Pest and in the Screen House Faculty of Agriculture, University of Sumatera Utara in Medan, from August to December 2017. This study used a Randomized Block Design (RBD) factorial with four replications. The first factor was rice varieties (Ciherang, Inpari 32 and IR 64) and the second factor was the number of pest introductions (2, 4, and 6 pairs). The results showed that all rice varieties (Ciherang, Inpari 32 and IR 64) were categorized as scale of 1 (resistant). The final rice black bug population was 19, 18, and 16 for Ciherang, IR64 and Inpari 32 respectively. Â Keywords: Resistance, rice varieties, Scotinophara coarctata, rice black bug.
