Abstract

In 2006-2008, we tested (3Z,6Z,9Z,12Z,15Z)-pentacosapentaene (pentaene) with the pheromone components (Z)-11-hexadecenyl acetate (Z11-16:Ac) and (Z)-9-tetradecenyl acetate (Z9-14:Ac), as sex attractants for four sympatric species of coneworms, Dioryctria Zeller (Lepidoptera: Pyralidae) in slash (Pinus elliottii Engelm.) and loblolly pine (Pinus taeda L.) seed orchards in Georgia and Louisiana, respectively. The addition ofpentaene increased catches of male southern pine coneworm, Dioryctria amatella (Hulst), in wing traps baited with Z11-16:Ac, whereas catches of Dioryctria disclusa Heinrich in traps baited with Z9-14:Ac were unaffected by the addition of pentaene. The effect of pentaene on male Dioryctria merkeli Mutuura & Munroe was inconsistent. In 2006, pentaene seemed to inhibit attraction of D. merkeli to traps baited with Z9-14:Ac, whereas in a subsequent trial in 2008, moths were equally attracted to Z9-14:Ac with or without the pentaene. We caught too few Dioryctria clarioralis (Walker) in any experiment for meaningful analyses. Our field results with pentaene and the unresolved complexity of the taxonomy, ecology, and management of southern coneworms support the need for a comprehensive examination of the chemical ecology of Dioryctria spp.

Two Antenna-Enriched Odorant Binding Proteins in Dioryctria abietella Tuned to General Odorants and Insecticides

“…In Dioryctria abietella, sex pheromones produced by female moths [(3Z,6Z,9Z,12Z,15Z)-pentacosapentaene and (9Z,11E)-tetradecadienyl acetate] were used for population monitoring and for the management of this pest in fields by designing strategies of pheromone-baited traps and mating distribution [3,4]. In addition, this pheromone-based control strategy was also applied to other Dioryctria species [5][6][7].…”

Hybrid Sex Pheromones of the Hibiscus Flower-bud Borer, Rehimena surusalis

“…This indicated that only Geometroidea and Noctuoidea, which show sister linkages in recent molecular phylogenetic trees (Regier et al 2009) use Type II sex pheromones and also that the origin of Type II pheromones may be from a common ancestor of the two taxa. However, recently hybrid type pheromone system has been reported in several Pyraloidea species (Cabrera et al 2001;Millar et al 2005;Leal et al 2005;Gibb et al 2007;Miller et al 2010;Lofstedt et al 2012;EI-Sayed et al 2013;Yan et al 2014). In Pyraustinae sensu lato, R. surusalis is the 4th species that has a hybrid type pheromone system as shown in two Conogethes species (Xiao et al 2010(Xiao et al , 2011b(Xiao et al , 2012El-Sayed et al 2013) and Omphisa anastomosalis (Yan et al 2014).…”

“…Recently so-called hybrid type of pheromone systems consisting of Type I and Type II compounds such as that of R. surusalis, are reported mainly in Crambid and Pyralid species (Cabrera et al 2001;Millar et al 2005;Leal et al 2005;Gibb et al 2007;Miller et al 2010;Löfstedt et al 2012;EI-Sayed et al 2013;Yan et al 2014).…”
