The introduction and establishment of campsomeris dorsata (Hymenoptera: Scoliidae) in Florida

Abstract

Summary Campsomeris dorsata is a hymenopteran scoliid that is endemic to South America, Central America, and parts of the West Indies. It has been used as a biological control agent in the past in Puerto Rico, Mauritius, and Florida to aid in reducing coleopteran pests in sugar cane agricultural systems. The status of C. dorsata's establishment in Florida has been unknown since intentional introductions to sugar cane fields occurring during the 1930s. We surveyed primarily coastal sites throughout the state of Florida and captured 91 females ranging from Osceola County to Miami-Dade County (north vs south) and from Broward County to Collier County (east vs west). The results from this study show that C. dorsata is well established in these areas of Florida, and might still be an important biological control agent of white grubs in sugar cane as well as turf production and maintenance.
