Responses of free-ranging coyotes to lures and their modifications.

abstract：:Volatile chemicals produced by plants mediate host location, mate-finding and oviposition behavior in insects. State-dependent response to plant cues allows for timing of foraging, mating and oviposition on ephemeral host plants or plant parts. Caloptilia fraxinella is a herbivorous specialist on the foliage of ash tr...
