Interpretive Summary: The Redbanded Stink Bug (RBSB) is an invasive stink bug species and is a polyphagous pest of cultivated crops and non-cultivated wild plants. Increase in soybean cultivation in 1960s-70s led to the spread of RBSB as an economic pest of soybean in South America and is a major soybean pest in Brazil, Argentina, and Uruguay. In early 2000s, RBSB started becoming an economic concern to US agriculture and is currently a key species in the stink bug complex that damage soybeans in many mid-southern states. RBSB mostly feed on plants' flowers and fruits, and cause extensive damage to soybeans and other economic leguminous crops. RBSB feeds on plant sap from stems, flowers, and foliage with a preference for pods and seeds causing flat pods, reduced seed weight, and germination. RBSB infestation may lead to more crop loss per capita compared to other stink bug species. RBSB are less susceptible to commonly used agrochemicals compared to other stink bug species complexes and has developed resistance to many commonly used insecticides. Alternative control strategies based on cultural, biological, ecological, and molecular methods have been investigated and reported in the recent years. In this review, we will report and discuss the distribution, sampling thresholds, biology, ecology, and various control strategies for integrated management of this major stink bug species in the last two decades.

Technical Abstract: The Redbanded Stink Bug (RBSB), Piezodorus guildinii Westwood (Hemiptera: Pentatomidae) is an invasive stink bug species and is a polyphagous pest of cultivated crops and non-cultivated wild plants. Increase in soybean cultivation in 1960s-70s led to the spread of RBSB as an economic pest of soybean in South America and is a major soybean pest in Brazil, Argentina, and Uruguay. In early 2000s, RBSB started becoming an economic concern to US agriculture and is currently a key species in the stink bug complex that damage soybeans in many mid-southern states.
