Olfactory responses of neotropical short-tailed singing mice, Scotinomys teguina, to odors of the mid-ventral sebaceous gland: discrimination of conspecifics, gender, and female reproductive condition.

abstract：:Resistant willow (Salix viminalis L.) genotypes react with a rapid hypersensitive response (HR) when attacked by the gall midge Dasineura marginemtorquens Bremi. In general, infected plant genotypes or species that react hypersensitively to pathogens accumulate salicylic acid (SA) locally and systemically. Thus, patho...
