Oebalus pugnax and Oebalus insularis, two species of stink bugs (Hemiptera: Pentatomidae), are major insect pests of rice in Florida. In the United States, O. insularis is only found infesting rice in Florida whereas O. pugnax is common in rice produced in the southern region of the country. This 2-year study aimed to identify egg parasitoids of rice stink bugs and estimate parasitism rates in both conventional and organic rice in southern Florida. Fifty-four commercial fields were sampled between summer and fall of 2022 and 2023. Wild Oebalus spp. eggs were collected using visual inspection of rice plants, and sentinel eggs produced in the laboratory were deployed in each field to increase parasitoid sampling. All eggs collected or recovered in the fields were kept in the laboratory for parasitoid emergence. Scelionid wasps were collected from both wild and sentinel eggs. Telenomus podisi was a predominant species. The presence of these wasps in the region and parasitism of rice stink bug eggs suggests a potential for the development of a novel management strategy relying on biological control for rice stink bugs.
