    Ecobiology and Control of Soybean Pod Borer Etiella spp. Hamoto. Pod borer caused by Etiella spp. is one of the most important pests of soybean in Indonesia, because it causes reduction in soybean yield both qualitatively and quantitatively. Two species of pod borers were found on soybean, i.e.. Etiella zinckenella Treitschke and E. hobsoni Butler. These two insects and damages they caused are difficult to distinguish, since they are quite similar to each other. They could be distinguised only by identification of morphological characteristics of the insect at each stage of their life cycles. In the laboratory, both pod borer species feed on pods of various legumes, while in the field they attack only few legume species. Approach to control this pest may be done by integration of different pest control components including crop rotation, crop sanitation from wildhost plants, varietal resistance, as well as use of parasitoid and recommended insecticides. Tnchogrammatoidea bactrae-bactrae seems to be a good parasitoid to control the pest, but more field trials need to be done to clarify further for its efficacy and economic value.
