A SEX ATTRACTANT FOR MALES OF THE EARLY CUTWORM, EUXOA TRISTICULA (LEPIDOPTERA: NOCTUIDAE)

“…Local populations of the target moth seemed low in both 1977 and 1978, the light trap catches being only about 0.5% of the total noctuids taken. Thus, although E. tristicula moths are readily attracted to light (Beirne 1971), our sex attractant proved more sensitive and very much more specific in sampling populations. Z9-12:Ac is alreafly known as a sex pheromone in grape berry moth Paralobesia viteana (Roelofs et a l .…”

A note on Systena frontalis [Coleoptera : Chrysomelidae] adults on lowbush blueberry, Vaccinium angustifolium
