PURPOSE Water hyacinth biological control research at the Engineer Research and Development Center ERDC, Vicksburg, Mississippi is currently focused on the rearing and release of the delphacid plant hopper, Megamelus scutellaris Berg Hemiptera Delphacidae, which has been in culture at the ERDC since 2010. Past failures to establish M. scutellaris were attributed to extreme summer temperatures at field sites therefore, a putatively temperature-tolerant strain of this insect was obtained from field-established stock in Florida. This report details the performance of original and new strains of M. scutellaris in greenhouse rearing and field released colonies in 2015.
