Isolation and Identification of Host Compounds Eliciting Attraction and Bite Stimuli in the Fruit Tree Bark Beetle, Scolytus Mediterraneus

Abstract: 

The host extracts and their chemical components eliciting attraction and bite stimuli in Scolytus mediterraneus were investigated. The ether extract exhibited the highest activity as expressed by the number of holes on a Styropor disk impregnated with the extract. Taxifolin (V). pinocembrin (I), and dihydrokaempferol (III) showed high activity, whereas naringenin (II), quercetin (VI), kaempferol (IV), 5,7-dihydroxy-2-methylchromone (VIII), and scopoletin (VII) exhibited low activity. These compounds may function as primary attractants of the beetle in the field. © 1974, American Chemical Society. All rights reserved.
