Abstract

Forty-five experimental and commercial olfactory attractants (lures) were tested under field conditions over a 30-month period to evaluate attractiveness to coyotes, elicited behaviors, and responses with lethal and simulated lethal coyote capture devices. The top 7 lures evaluated in spring and summer test periods that produced the highest simulated coyote capture rates with trap rings, M-44 heads, and break-away snares were WU 15-20%, Sheep Liver Extract, and (Carman's) Canine Distance Call Lure; (Carman's) Final Touch, Rotten Meat Odor, and TMAD 10%; and Estrous Urine Fractions, respectively.
