Resumen en inglés

In this study, we evaluated the responses of Triatoma dimidiata Latreille (Hemiptera: Reduviidae) to volatiles emitted by conspecific females, males, mating pairs and metasternal gland (MG) extracts with a Y-tube olfactometer. The volatile compounds released by mating pairs and MGs of T. dimidiata were identified using solid-phase microextraction and coupled gas chromatography-mass spectrometry (GC-MS). Females were not attracted to volatiles emitted by males or MG extracts; however, they preferred clean air to their own volatiles or those from mating pairs. Males were attracted to volatiles emitted by males, females, mating pairs, pairs in which the male had the MG orifices occluded or MG extracts of both sexes. However, males were not attracted to volatiles emitted by pairs in which the female had the MG orifices occluded. The chemical analyses showed that 14 and 15 compounds were detected in the headspace of mating pairs and MG, respectively. Most of the compounds identified from MG except for isobutyric acid were also detected in the headspace of mating pairs. Both females and males were attracted to octanal and 6-methyl-5-hepten-2-one, and males were attracted to 3,5-dimethyl-2-hexanol. Males but not females were attracted to a seven-compound blend, formulated from compounds identified in attractive MG extracts.

Resumen en inglés

Two species in the genus Monochamus Dejean (Coleoptera: Cerambycidae: Lamiinae) have recently been shown to have the same male-produced sex pheromone, 2-undecyloxy-1-ethanol (monochamol), suggesting that other congeners may share the same pheromone. We tested that hypothesis by conducting field bioassays of monochamol, in combination with bark-beetle pheromones and the host plant volatiles ethanol and α-pinene, in southern British Columbia, Canada. We captured 603 Monochamus clamator (LeConte), 63 Monochamus obtusus Casey, 245 Monochamus scutellatus (Say) (tribe Monochamini), and 42 Acanthocinus princeps (Walker) (tribe Acanthocinini). All three Monochamus species were significantly attracted to the combination of monochamol and host plant volatiles, whereas bark-beetle pheromones plus plant volatiles and plant volatiles alone were minimally attractive. Adding bark-beetle pheromones to the monochamol plus plant volatiles treatment synergised attraction of M. clamator, but not the other two Monochamus species. Acanthocinus princeps was most strongly attracted to the combination of bark-beetle pheromones and plant volatiles, and did not appear to be affected by the presence or absence of monochamol in baits. We conclude that monochamol is a likely pheromone component for the three Monochamus species, and that monochamol plus host plant volatiles is an effective attractant for these and perhaps other North American Monochamus species.

Resumen en alemán

On a démontré récemment que deux espèces du genre Monochamus Dejean (Coleoptera: Cerambycidae: Lamiinae) possédaient la même phéromone sexuelle mâle, le 2-undécyloxy-1-éthanol (monochamol), ce qui laisse croire que d'autres congénères pourraient aussi avoir cette même phéromone. Nous avons testé cette hypothèse par des bioessais de monochamol en nature en combinaison avec des phéromones de scolytes et des produits volatils de la plante-hôte, l’éthanol et l’ α-pynène, dans le sud de la Colombie-Britannique, Canada. Nous avons capturé 603 Monochamus clamator (LeConte), 63 Monochamus obtusus Casey, 245 Monochamus scutellatus (Say) (tribu des Monochamini) et 42 Acanthocinus princeps (Walker) (tribu des Acanthocinini). Les trois espèces de Monochamus sont fortement attirées par la combinaison de monochamol et de produits volatils de la plante-hôte, alors que les phéromones de scolytes additionnées de produits volatils de la plante hôte et les produits volatils de la plante hôte seuls exercent très peu d'attraction. L'addition de phéromones de scolytes à la combinaison de monochamol et de produits volatils de la plante hôte a un effet synergique d'attraction chez M. clamator, mais non chez les deux autres espèces de Monochamus. Acanthocinus princeps est le plus fortement attiré par la combinaison de phéromones de scolytes et de produits volatils de plante et ne semble pas être affecté par la présence ou l'absence de monochamol dans les appâts. Nous concluons que le monochamol est vraisemblablement l'une des composantes de la phéromone des trois espèces de Monochamus et que la combinaison de monochamol et de produits volatils de la plante hôte a un pouvoir efficace d'attraction chez ces espèces et peut-être chez d'autres espèces nord-américaines de Monochamus.
