Aggregation pheromone for the pepper weevil,Anthonomus eugenii cano (Coleoptera: Curculionidae): Identification and field activity.

abstract：:MaleGrapholitha molesta hairpencil components are ethyltrans-cinnamate, mellein, methyl jasmonate, and methyl 2-epijasmonate. The natural behavioral effect elicited by hairpencil-displaying males during courtship in attracting sex-pheromone-releasing females from several centimeters away can be duplicated by mixtures ...
