Urinary signaling pheromone and specific behavioral response in tree shrews (Tupaia belangeri) : I. Basic investigations for a bioassay.

abstract：:The feasibility of using the synthetic sex pheromone, disparlure, as a mating confusant of the nun moth (Lymantria monacha L.) was investigated on wild populations occurring in outbreak proportions in Poland and in low density in Czechoslovakia. The size of experimental plots ranged from 1 to 12 hectares. The amounts ...
