Two-Component Sexual Attractant for Male Batrachedra pinicolella (Zell.) (Lepidoptera: Batrachedridae)

Abstract

Contrary to an earlier report, male B. pinicolella are shown to respond to synergistic blends of (Z)-5-decenyl acetate with its corresponding alcohol analogue. Four other, decenyl or dodecenyl, com pounds are reported as potent trapping inhibitors. This pattern of pheromonal attraction and inhibition conforms with that found in some species groups of Coleophoridae, supporting the view of a close phylogenetic origin of the two families.
