Mammals methyl anthranilate

FIGURE 13.1 Methyl anthranilate deters birds from feeding and stimulates feeding in mammals. Capsaicin deters mammals from feeding but stimulates birds. 

Birds may have a trigeminal receptor for o-aminoacetophenone and methyl anthranilate, analogous to the capsaicin receptor in mammals (Clark and Shah, 1994). 

USEPA (2001) Selected Mammal and Bird Repellents 9,10-Anthraquinone (122701), 1-Butanethiol (1-Butylmercaptan) (125001), Fish Oil (122401), Meat Meal (100628), Methyl Anthranilate (128725), Red Pepper (Chile Pepper) (070703) Fact Sheet http //www.epa.gov/oppbppdl/ biopesticides/ingredients / factsheets / factsheeLmam -bird-repel.htm (last accessed 30 April 2010). 

This real-world exercise tests the efficacy of a feeding repellent in free-ranging mammals. It constitutes the counterpart to the repellent effect of methyl anthranilate on feeding by birds (see Chap. 3). The experiment works at any place with wild squirrels and in any season. The many mammal repellents on the market are aimed against deer, predators such as raccoons, foxes and coyotes, and rodents such as voles, mice, squirrels, woodchucks, and others. Mammal repellents are known under names such as copper naphthenate, trimethacarb, zinc naphthenate, and ziram.
