【 摘 要 】

Soybean (Glycine max L.) is one of the most important crops which production continues to be improved in all areas of soybean cultivation centers in an effort to maintain the availability of soybean foods, including Southeast Sulawesi. The purpose of this study was to analyze the contribution of pod borer pests to soybean crop production. Methods of direct observation were made on observed variables, including species and population of pest pod borer, intensity, and crop production. The result that found four types of pod borer pests are Nezara viridula, Riptortus linearis, Etiella zinckenella, and Leptocorisa acuta, each with a different population and contribution to the intensity of pod damage. The result of path analysis showed that directly population of N. viridula (61.14) and E. zinckenella (66.44) gave positive contribution in increasing pod damage, by 0.332 and 0.502 respectively, while the negative contribution was shown by population of R. linearis and L. acuta. Damage of the pod causes increased production of low soybean is only about 0.202, therefore required appropriate control techniques to control pod borer pests populations in soybean crops.
