Abstract
Research has been carry out to study the density of population test of yellow stem borer S incertulas
and varieties Rice to preferences and levels of deadheart and whiteheart attack on SRI cultivation is
done in the home screen Experimental Station Department of Plant Pests and Diseases Jatinangor
Faculty of Agriculture, Padjadjaran University, from October 2011 until January 2012. The design used
was a randomized block design with two factors factorial pattern and replicated three times. The first
factor is the density population of yellow stem borer consists of four levels ie p1: 5 pairs of moth, p2 : 10
pairs of moth, p3: 15 pairs of moth, and p4 : 20 pairs of moth. Second factor is a rice varieties consists
of four levels, namely: v1: Inpari-1 varieties, v2 : Inpari-13 varieties, v3 : Sarinah varieties, and v4 :
Ciherang varieties. The results showed that 5 pairs moth of yellow stem borer can caused deadheart
and whiteheart attack on the varieties Sarinah lowest and the varities Inpari-1 highest.
