The purpose of this study are a) to compare the influence of two types of wild plants (E. dulcis, P. karka) and rice plants against the number of eggs laid and parasite percentage ; b) compare the treatment effect of wild plants (E. dulcis, P. karka) as reservoir rice stem borer parasitoid egg white to the average number of white rice stem borer eggs are laid and the parasitasi percentage. The first field trial using a randomized block design with three treatments and 10 replications. Treatment plant is E. dulcis, P. karka, and rice plants. Observed variable is the average number of white rice stem borer eggs and parasitasi percentage by T. rowani. In the second field experiment, the experiment conducted in a separate place is located about 300 meters. In the first place the rice planted in adjacent plots with plots of wild plants and placed second as a comparator (300 m) of rice plants grown on plots without swath of wild plants. Experiments conducted during the planting period. Observed variable is the average number of white rice stem borer eggs and parasitasi percentage by T. rowani. From the results of research can be concluded as follows: Weed plants purun tikus most preferred to lay eggs by white rice stem borer (S. innotata).The spread of the highest egg parasitoids contained in white rice stem borer eggs laid on plants weeds purun tikus. The number of eggs laid on rice plants are planted side by side with wild rodents and weeds purun tikus and parupuk fewer than the number of eggs laid on rice plants grown without wild plants. The percentage of egg parasitoids parasitasi white rice stem borer, T. rowani on white rice stem borer eggs are laid in rice plants are planted side by side with wild plants is higher than that grown on plants without wild. Wild on E. and P. dulcis karka found 12 species of predators, six species of parasitoids.
