Glycerides of Lard as an Extender for Cue-lure, Medlure, and Methyl Eugenol in Formulations for Programs of Male Annihilation23

Abstract
Tray tests were conducted to determine the comparative efficiency of carriers and extenders for cuelure, medlure, and methyl eugenol in programs of male annihilation. Certain so-called glycerides of lard extended the attractancy of all 3 lures when 7–10% of Myverol was added to 100 ml of lure. This thickening-agent may make it possible to eliminate male melon flies, Dacus cucurbilae Coquillett, and Mediterranean fruit flies, Ceralitis Capetata (Wiedemann), without use of solid carriers and could he a valuable addition to eradication programs against the oriental fruit fly, D. dorsalis Hendel, when it is used in conjunction with cane-fiber squares.
