Abstract. White rice stem borer was recorded as a mojor pest of rice in tidal swampland. Thes pest attacks the rice plant from the seedling to the generative stages. But in the rice field grown ny purun tikus (Eleocharis dulces ), the  damage due to white rice stem borer is very low. The results showed that of the five weeds growing in tidal swamplands, white rice stem borer prefers to lay their eggs on purun tikus. Even the pest is capable of completing their life cycle in the specific weeds of swamplands. Extract of purun tikus sprayed on rice plants was also selected by these pests to lay  their eggs. Extract derived from fresh material of purun tikus was preferred by  the  pest that derived from drained material. The results of this study prove that purun tikus had the ability to attract the adults of white rice stem borer to lay their eggs. In addition, purun tikus is also used by beneficial insects in order to servive. The existence of purun tikus around rice field is very  significant in reducing the demaging rate of white rice stem borer. With these capabilities, the existence of purun tikus  around rice field is very significant in reducing the damaging rate of white rice stem borer in tidal swampland.



 Rice is an ideal host plant for many insect species. There are over 800 insect species.  Insect species  damaging rice in one way or another, although the majority of them do very little damage. All parts of the plant are vulnerable to insect feeding from the time since in seedling to the harvest. In tropical Asia only about 20 species are mojor importance and occurrence regulary. Saveral Species that were earlier considered minor pests have recently become major pests, whereas the incidence of  a few others has considerably declined (Dale 1994).
