Interpretive Summary: Interpretative summary Fourteen species of stink bugs have been identified in rice in Latin America. The genus Tibraca represents the largest pentatomid on rice in this region. Two species, T. limbatriventis Stal and T. obscurata Bergroth, have been reported from commercial rice fields in Latin America. Tibraca limbatriventis is emerging as an important rice pest in several areas of Colombia, Venezuela, Brazil, and the Dominican Republic but little data is available on its biology and development in rice. Data on the number of instars and time to complete development is important for the construction of life tables for these pests. Information on the time to complete development and the number of instars will help in the evaluation for resistance and damage. Information on factors affecting development of stink bug populations under field conditions is of primary importance in the development of IPM strategies. In this work, we report on T. obscurata and T. limbatriventis development on rice plants in Southwestern Colombia

Technical Abstract: Technical Abstarct The development of Tibraca obscurata Bergroth and T. limbatriventis Stal was studied on rice in Southwestern Colombia. Both species completed development in five instars. Tibraca limbatriventis required more time to complete development than T. obscurata. Females of T. limbatriventis required more time to complete development than males of the same species. T. limbatriventis females live significantly longer than males. T. limbatriventis can oviposit over 200 eggs in an 86 day oviposition period
