The chemical sense is of crucial importance for insects to navigate within their often complex habitats. For chemical information transfer between conspecifics, insects use pheromones, semiochemicals that have been shown to mediate sexual and social communication of innumerable species. Thereby, pheromones contribute to the successful reproduction of insects and help to maintain the integrity of insect communities. Insect pheromone research is one of the basic columns of the interdisciplinary research field of Chemical Ecology bringing together the expertise of chemists, ecologists, behavioral biologists, neurobiologists and increasingly also molecular biologists. Since the identification of the silkmoth pheromone by Butenandt and co-workers in 1959, tremendous advances in analytical chemistry allowed the characterization of hundreds of bioactive molecules many of which have become part of environmentally sound control methods for insect pests. Significant progress has also been made in our understanding of the biochemical and molecular mechanisms underlying pheromone biosynthesis and perception. This knowledge is increasingly used to answer ultimate questions concerning the evolution of communication systems and the involvement of chemical signals in sexual selection and other evolutionary processes. For this special issue we invite the submission of high quality original research papers and mini-reviews covering all aspects of insect pheromone chemistry and pheromone mediated insect behavior.

Abstract: The sex pheromone components of the apple leafminer moth, Phyllonorycter ringoniella, have been identified as (Z)-10-tetradecenyl acetate (Z10-14:Ac) and (E,Z)-4,10-tetradecadienyl acetate (E4Z10-14:Ac). A 3-µg mixture of the two components in a 10:1 ratio showed optimal attraction of males in the field, and lures impregnated with the binary blend are commercially available. Recently, however, their performance has been reported to be declining in apple orchards treated with pheromone-based communication disruptants. We therefore reinvestigated female pheromones and male responses in P. ringoniella. In a series of field trap experiments, we confirmed the optimal blend of Z10-14:Ac and E4Z10-14:Ac to be around 9:1, respectively, and that the lure's attractiveness improves greatly when the total amount of attractant is increased to 30 to 300 µg. Moreover, we identified dodecyl acetate (12:Ac), (Z)-8-dodecenyl acetate (Z8-12:Ac), and (E)-10-dodecenyl acetate (E10-12:Ac), which were not previously reported as a sex pheromone of this species, in extracts from the female body. The number of males captured significantly increased by 34.1% to 71.4% when 1 µg of E10-12:Ac was added to 30 µg of a 9:1 mixture of Z10-14:OAc and E4Z10-14:Ac, although no significant activity was found in 12:Ac and Z8-12:Ac. These results indicate that lures for monitoring P. ringoniella could be improved by increasing the amounts of the pheromone components and adding E10-12:Ac.

Title: Unique responses to sexual pheromones in parasitoids of the genus Cotesia: males are strongly attracted to virgin females, but repelled by mated females

Abstract: The reproductive success of parasitoids is tightly linked to the females’ ability to find hosts for their offspring, but optimal foraging for food and mates is also essential to maximize adult lifespan and fitness. Having a haplo-diploid sex determination system, female hymenopteran parasitoids are able to reproduce without mating, but this will result in only males. Certainly for males, but also for female parasitoids it will be much to their advantage to mate before eggs are deposited in or on hosts. Therefore an effective mate-finding strategy can be expected in parasitoids. Yet, the use of sex pheromones in parasitoids has been rarely studied and it remains largely unknown how male and female parasitoids locate each other. In the current study we investigated possible attraction (and repellency) between the sexes of two braconid parasitoids of the genus Cotesia. Males of Cotesia marginiventris and Cotesia glomerata were found to be strongly attracted to conspecific virgin females, but they were repelled by mated females and by males of the same species. The repellency of mated females was only evident hours after mating, implying a change in their release of pheromones. Females of the Cotesia species showed no response to the odors of conspecific individuals, except that Cotesia glomerata females appeared to be repelled by mated males. The pheromones appear to be highly specific, as the two species did not respond to each other’s pheromones. We discuss these exceptional responses in the context of optimal mate finding strategies.
