1. This is Dr. Frank Mead's last editorship of Entomology's sample identifications for Tri-ology. Frank has done this service since the mid-1960's, taking over from Dr. Robert Woodruff who began in May 1962. Frank took this assigment with enthusiasm. For about 30 years, readers have benefitted from Frank's desire to provide timely and useful collection data relevant to Florida's agricultural resources. --Nancy C.
