Seasonal Occurrence of Male Sesiidae in North Central Florida Determined with Pheromone Trapping Methods

The seasonal occurrence of 20 species of male Sesiidae was determined in Alachua and Marion counties in north central Florida during 1975-77. Sticky traps were baited with the sex pheromones of the lesser peachtree borer, Synanthedon pictipes (Grote and Robinson), and the peachtree borer, Synanthedon (= Sanninoidea) exitiosa (Say), (E,Z)- and (Z,Z)-3, 13-octadecadien-1-ol acetate, respectively. These materials or the corresponding alcohols or binary mixtures of the acetates plus alcohols attracted 15 species of 25 currently recognized Sesiidae from Florida plus the following 5 species not reported before: Synanthedon decipiens (Hy. Edwards), Synanthedon fatifera Hodges, Carmenta bassiformis (Walker), Carmenta suffusata Englehardt, and Alcathoe carolinensis Engelhardt.
