“…Hooper et al (2002) deduced that the attractive effect could be caused by incidental structural similarity of aphid sex pheromones to (yet unknown) pheromones of these lacewing species. This hypothesis seems to be supported by reports on a maleproduced compound, (1R,2S,5R,8R)-iridodial, identified from some Nearctic green lacewing species, which attracts males (Zhang et al 2004(Zhang et al , 2006a, and shows structural similarities to NEPOH and NEPONE. Additionally, catches by NEPOH and NEPONE are strongly male-biased (e.g., Boo et al 1999;Hooper et al 2002 and results of this study), again supporting the idea of NEPOH and NEPONE mimicking structurally related lacewing sex pheromones.…”

“…Several studies have reported on the attractive effect of aphid sex pheromone components (enantiomers of nepetalactol and nepetalactone) to green lacewings; e.g., Chrysopa, Peyerimhoffina and Nineta species (Boo et al 1998Hooper et al 2002;Koczor et al 2010;Weihrauch 2006;Zhang et al 2004Zhang et al , 2006aZhu et al 2005). Hence, from a practical point of view, the combination of aphid sex pheromone compounds and the ternary floral bait could yield benefits by attracting a wider range of predatory insects.…”

Aphid Sex Pheromone Compounds Interfere with Attraction of Common Green Lacewings to Floral Bait

Common green lacewings (Chrysoperla carnea complex) form a group of generalist predators important for biological control. Several reports show attraction of these insects to plant volatiles, and a highly attractive ternary compound floral bait has been developed. With aphids being a preferred prey of larvae, one might expect these lacewings to be attracted to aphid semiochemicals, for instance, to aphid sex pheromones, as found for several other green lacewing species. However, in a previous study, we found that traps containing aphid sex pheromone compounds (1R,4aS,7S,7aR)-nepetalactol (NEPOH), (4aS,7S,7aR)-nepetalactone (NEPONE), and a ternary floral bait attracted fewer individuals than those containing the ternary floral bait alone. In the present study, possible causes for this effect of NEPOH and NEPONE on trap capture were studied. We established that C. carnea complex catches in traps with a ternary floral lure were not influenced by the presence of Chrysopa formosa individuals in traps (attracted by NEPOH and NEPONE) or by synthetic skatole (a characteristic component of Chrysopa defense secretion). A direct negative effect of NEPOH and NEPONE on attraction of C. carnea complex was found, suggesting active avoidance of these aphid sex pheromone components. This finding is surprising as the larvae of these lacewings prey preferentially on aphids. Possible mechanisms underlying this phenomenon are discussed.

RESUMENSe revisan las especies de crisópidos presentes en la fauna de la Península Ibérica e Islas Baleares donde, hasta la fecha, están representadas por 50 especies pertenecientes a 13 géneros. Tras una diagnosis de la familia y citar algunos elementos sobre su historial paleontológico y su distribución, se aportan algunos datos generales sobre su morfología y su biología, sus estadios juveniles y comportamiento, y se comenta una breve introducción sobre la historia en el conocimiento de la familia, y en particular en la Península Ibérica y Baleares. Se anotan algunas correcciones en las fechas de publicación de algunos taxa que afectan a la taxonomía, y por ello se propone a Rexa almerai (Navás, 1919) n. comb. como sinónima anterior de Rexa lordina Navás, 1920 n. syn. Se incluye una lista de las especies pertenecientes a la fauna de la Península Ibérica y Baleares, una clave de identificación de los imagos de las subfamilias, géneros y especies citadas, y una clave de sus larvas a nivel genérico. De cada una de estas especies se recopilan y se anotan todas las referencias bibliográficas existentes desde 1972, relativas a las especies de la zona estudiada, tanto con la denominación actualmente aceptada, como de sus sinonimias y/o cualquier otra combinación nomenclatural bajo las cuales han sido citadas. También de cada una de las especies se anotan los datos conocidos y los ahora aportados (299 nuevos ejemplares de 25 especies) sobre su distribución general, aspectos de su morfología externa y/o genital, así como de su variabilidad, estadios juveniles, biología, fenología y distribución altitudinal y geográfica en la península y archipiélago balear, en base a un total de 20.667 ejemplares estudiados.http://lsid:zoobank.org:pub:DAF40D47-BB5B-444B-9A3C-463BBB4F5382Palabras clave: Insecta; Neuroptera; Chrysopidae; Revisión; Taxonomía; Faunística; Morfología; Península Ibérica; Islas Baleares; España; Portugal. SUMMARY Green-lacewings (Insecta, Neuropterida, Neuroptera: Chrysopidae) of the Iberian Peninsula and Balearic IslandsThe present contribution reviews the green lacewing fauna of the Iberian Peninsula and Balearic Islands where, to date, 50 species belonging to 13 genera are known to occur. After a diagnosis of the family Chrysopidae, its paleontological history and distribution, as well as some general data on its morphology and biology, juvenile stages and behavior are presented. This general information is followed by a brief history of studies on the family, and particularly those on the Iberian Peninsula and Balearic Islands. Some corrections are reported for earlier publications dates that have undergone taxonomical changes. Thus, Rexa almerai (Navás, 1919) n. comb. is proposed as junior synonym of Rexa lordina Navás, 1920 n. syn.; and is included in the list of chrysopid species belonging to the fauna of the Iberian Peninsula and Balearic Islands. A key for identifying imagoes of the subfamilies, genera, and species recorded from the region and a generic level key for the larvae are presented. For th...

SummaryFollowing our earlier approach to the synthesis of dihydronepetalactones, all eight stereoisomers of trans-fused iridomyrmecins were synthesized starting from the enantiomers of limonene. Combined gas chromatography and mass spectrometry including enantioselective gas chromatography revealed that volatiles released by the endohyperparasitoid wasp Alloxysta victrix contain (4S,4aR,7S,7aR)-iridomyrmecin of 95–97% ee and stereochemically pure (4S,4aS,7R,7aS)-iridomyrmecin as a minor component.
