(3Z,6Z,9Z,12Z,15Z)-Pentacosapentaene and (9Z,11E)-Tetradecadienyl Acetate: Attractant Lure Blend for Dioryctria ebeli (Lepidoptera: Pyralidae)

Feeding damage by larval coneworms (Lepidoptera: Pyralidae) on flowers and cones of pines can cause significant economic losses in pine seed orchards in the southern USA (Ebel et al. 1980, USDA Forest Service GTR SE-8, Asheville, NC). The south coastal coneworm, Dioryctria ebeli Mutuura & Monroe, is a common pest in seed orchards of slash pine (Pinus elliottii L.) in the coastal region of southeastern USA, particularly Florida (Ebel et al. 1980). With multiple generations per year, infestations of D. ebeli can be severe, especially in seed orchards infected by the southern pine cone rust, Cronartium strobilinum Hedgc. & Hahn (Merkel 1958, J. Forestry 56:651 ).
