Abstract: Paddy Rice Stemborer
Attact and The Role of Parasitoid in Control That Population atSimultaneous and
Stagered Ricefield. The arrangement of suistable agriculture in Baliwhich
appropriate with Bali governments mission : Bali Clean and Green Go to Organic.
Theconcept of modern agriculture look like contradiction with the aspects
suistainableagriculture. The aspect of cultivation have been done by local
agriculture community in Balicall it Subak for many years, but the attack of

out at simultaneousplanting area (Subak Sidakarya, Denpasar Selatan District)
and at staggered planting area(Subak Buaji, Denpasar Timur District). The
result of this experiment showed that damageintensity of rice stemborer at
simmultaneus planting was lower than at staggered plantingarea. There are four
species stemborer at simultaneous planting area and at staggered plantingareas,
namely Scirpophaga incertulas, Sesamia inferens, Chilo suppressalis, and
Chilopolychrysus. Three kinds of egg parasitoids were found to decrease the
population of ricedstemborer. They were Tetrastichus schoenobii, Telenomus
