title: Evaluation of various substances to increase adult Stomoxys calcitrans (Diptera: Muscidae) collections on alsynite cylinder traps in north Florida.
abstract: During 1993-1995, field studies evaluated various volatile substances to increase the catch of adult stable flies, Stomoxys calcitrans L., on adhesive-coated translucent fiberglass (Alsynite) cylinder traps. Dry ice, 1-octen-3-ol (referred to as octenol), acetone, 4:1:8 mixture of 1 octen-3-ol: 3-n-propylphenol: 4-methylphenol, and an eye gnat (Hippelates) attractant were tested. Using dry ice as a baseline, the latter 4 treatments also were considered as possible alternatives to carbon dioxide. Dry ice significantly increased fly collections on cylinders as much as 25-fold compared with cylinders with no odor. Although trap collections increased by approximately 4% with addition of octenol (release rate approximately 18.0 mg/h), it was not significantly different when compared with dry ice alone. Fly collections on cylinders baited with octenol only were significantly lower than dry ice and not significantly different from cylinders with no odor. Collections from Alsynite cylinders baited with either acetone released at approximately 62.0 mg/h or eye gnat bait plus sand caught significantly more stable flies than no odor. However, neither substance increased fly collections as much as dry ice. The 4:1:8 phenolic mixture (released at either 0.7 mg/h or 20.0 mg/h) significantly increased fly collection on cylinders nearly 6-fold compared with no odor and warrants further investigation as an alternative to carbon dioxide for sampling stable flies.
