Methionol
Based on 1 Customer Validation
Methionol is a sulfur-containing flavor compound and also a component of aggregation pheromones produced by males. Methionol exists in fermented coconut milk and wine. Methionol has an odor similar to boiled cabbage, and imparts cauliflower-like off-flavors to wine when its content exceeds the perception threshold. Methionol attracts both male and female adults of Knulliana cincta cincta, and mainly attracts female adults of Elaphidion mucronatum.

Result:Captured 15 Knulliana cincta cincta adults in Illinois, with a mean of 1.4 beetles per replicate, significantly higher than captures in traps baited with sulfoxide, methionol + sulfoxide, or solvent control (F3,34=22.3, P<0.0001, Tukey test, P<0.05).
Captured 9 Elaphidion mucronatum adults in Illinois, with 78% in methionol-baited traps, resulting in a mean of 1.8 beetles per replicate, significantly higher than other treatments (F3,15=11.7, P=0.0013).
Captured 123 Knulliana cincta cincta adults in Iowa, with a mean of 14.2 beetles per replicate, significantly higher than captures in traps baited with sulfoxide or solvent control (F3,23=16.6, P=0.0009, Tukey test, P<0.05), while captures in methionol + sulfoxide-baited traps were intermediate.
