An evaluation of repellents to suppress browsing by possums.

摘要: The efficacy in feeding suppression trials with possums (Trichosorus vulpecula Kerr) of six synthetic odorous chemicals uniquely associated various the Mustelidae species and red fox (Vulpes vulpes) has been evaluated respect to several proprietary repellents. predator odors, two repellents, other repellent formulations (olive oil petroleum jelly a fermented egg odor cocktail) were applied as 5% w/v solutions paraffin foliage ofPinus radiata seedlings extent browse compared that on treated Treepel, an effective egg-based already available commercially. All four mustelid odors [(∓)-2-n-propylthietane, (∓)-3-n-propyl-1,2-dithiolane, 2,2-dimethylthietane, 3,3-dimethyl-1,2-dithiolane] volatile compound from urine (Δ3-isopentenyl methyl sulfide) shown be more or at least equally Treepel. This was true also one commercial Gori, which contained bitrex formulation. most compounds will when administered adhesives surfactants further development possum repellents longer field lives.
