Evaluating Electrophysiological and Behavioral Responses to Volatiles for Improvement of Odor-Baited Trap Tree Management ofConotrachelus nenuphar(Coleoptera: Curculionidae)

Abstract: Plum curculio, Conotrachelus nenuphar (Herbst), one of the most important pests of apple in eastern and central North America, is usually managed in New England apple orchards by multiple full-block insecticide applications. Efforts to reduce insecticide inputs against plum curculio include using an "attract and kill" approach: odor-baited trap trees deployed in the perimeter row of apple orchards. The standard approach is based on baiting apple trees with two olfactory stimuli, the fruit volatile benzaldehyde… Show more

“…By establishing a few odor-baited trees on perimeter rows of apple orchards, apple growers can monitor C. nenuphar oviposition activity accurately and inexpensively [6]. The attract-and-kill strategy developed by Leskey et al [8,27] represented a new reduced input strategy for managing C. nenuphar in apple orchards, based on the application of insecticides to a few perimeter-row odor-baited trap trees, rather than the entire perimeter row. A similar approach has been developed to manage C. nenuphar in blueberries [28].…”

“…However, finding methods that limit weevil movement from trap bushes could help reduce spillover injury to adjacent unbaited bushes; thus, restricting insecticide use to even fewer bushes. It is possible, for example, to improve C. nenuphar attraction to, and retention on, trap bushes by improving the attractive lure (e.g., Reference [39]). Bee-safe methods to kill adults, such as insecticidal nets [40], could also be placed around the base of trap bushes for an “attract-and-kill” strategy to manage these weevils.…”

“…Furthermore, the attractiveness of palm wine alcohol extracts of senesced banana leaf material, and the presence of the attractant (2 R ,5 S )‐theaspirane as demonstrated by coupled GC–EAG suggests the potential for using such extracts, instead of bulky banana leaf materials, as bait material for C. sordidus trapping, with the extracts also being easier to preserve than corms, rhizomes and whole‐leaf material. Further work is required in application of findings in this work since attractiveness of kairomones can be influenced by several factors …”
