Materials and tools used in this research is cropping Rice, meter, Aqua Glass, Peg, paper labels, plastic rope, Scissors, Box collection, Microscope, Petridis, Calculators, digital camera for documentation and stationery. The observation of the larval population of S. exempta in rice paddy fields in the village molompar two north, found that populations of this pest on plant age 60 HST is 3.3 tails. Then the next observation at the age of 67 plants as much as 2.1 HST observations of the tails and the third at the age of 75 plants of S. exempta HST population is 2 larvae.
