moth scale derived kairomones used by egg larval parasitoid Ascogaster quadridentata to locate eggs of its host cydia pomonella
Journal of Chemical Ecology, 1999Co-Authors: Naomi C Delury, Gary J R Judd, Gerhard Gries, Regine Gries, Grigori KhaskinAbstract:We determined that location of host (Cydia pomonella) eggs by Ascogaster quadridentata is mediated by kairomones, investigated potential sources of the kairomones and identified a blend of kairomones from the source that was attractive to A. quadridentata. In Y-tube olfactometer bioassays, female A. quadridentata were attracted to Porapak Q-collected volatiles from female C. pomonella scales and eggs, but not to C. pomonella sex pheromone. Scales of C. pomonella were also attractive to male A. quadridentata. Coupled gas chromatographic–electroantennographic detection analysis of scale volatile extracts revealed numerous compounds that elicited responses from male or female A. quadridentata antennae, including heptanal, octanal, nonanal, decanal, undecan-2-one, dodecanal, pentadecan-2-one, (Z)-6-pentadecen-2-one, (Z)-9-hexadecenal, (Z)-6-heptadecen-2-one, and 3,7,11-trimethyl-2E,6E,10-dodecatrien-1-ol acetate. A synthetic blend of these compounds at quantities and ratios equivalent to Porapak Q scale volatile extract was attractive to female A. quadridentata in a Y-tube olfactometer bioassay.

Sex Pheromone of Ascogaster quadridentata, a Parasitoid of Cydia pomonella
Journal of Chemical Ecology, 1999Co-Authors: Naomi C Delury, Gary J R Judd, Gerhard Gries, Regine Gries, John J. BrownAbstract:Porapak Q volatile extracts of female Ascogaster quadridentata , an egg-larval endoparasitoid of codling moth, Cydia pomonella , bioassayed in Y-tube olfactometers attracted male, but not female, A. quadridentata . Coupled gas chromatographic–electroantennographic detection (GC-EAD) analysis of bioactive extracts revealed three compounds that elicited responses by male A. quadridentata antennae. GC-mass spectra (MS) indicated, and comparative analyses of authentic standards confirmed, that these compounds were ( Z , Z )-9,12-octadecadienal, ( Z )-9-hexadecenal, and 3,7,11-trimethyl-6 E ,10-dodecadienal. ( Z , Z )-9,12-Octadecadienal alone attracted laboratory-reared male A. quadridentata in Y-tube olfactometer and field-cage bioassays, and attracted feral A. quadridentata in a field experiment. This sex pheromone could be used to help detect populations of A. quadridentata , delineate their distributions, and determine potential sources of parasitoids for capture and release in integrated programs for control of C. pomonella.
