Abstract

(Z) -11-Hexadecenal (Z11-16ALD) is a component of the sex pheromone, or a sex attractant, of a number of moth species. Traps baited with this compound in early spring in eastern Washington State captured numbers of males of Egira rubrica (Harvey), Stretchia plusiaeformis (H. Edwards), and Annaphila danisticta (Grote) (all Lepidoptera: Noctuidae), indicating its function as a sex attractant for these species. This new knowledge may be important to pest managers that monitor moths with Z11-16ALD because such non-target responders to a lure can increase monitoring costs and be counted as “false positives” for pest species.


Sumário

(Z)-11-Hexadecenal (Z11-16ALD) es un componente de la feromona sexual o un atrayente sexual de varias especies de polillas. Las trampas cebadas con este compuesto a principios de la primavera en el este del estado de Washington capturaron un número de machos de Egira rubrica (Harvey), Stretchia plusiaeformis (H. Edwards) y Annaphila danisticta (Grote) (todos Lepidoptera: Noctuidae), lo que indica su función como atrayente sexual para estas especies. Este nuevo conocimiento puede ser importante para aquellos que manejan estas plagas y monitorean las polillas con Z11-16ALD porque tales respondedores no objetivo a un señuelo pueden aumentar los costos de monitoreo y ser contados como “falsos positivos” para las especies de plagas.
