Koczor, S.: Examination of chemical ecology some important European tarnished plant bugs (in Hungarian). PhD Theseis. Eötvös Loránd University, Budapest, 2013. p. 98

Summary

The studies I carried out unambiguously proved that two floral volatile compounds, the phenylacetaldehyde and (E)-cinnamaldehyde attract the European tarnished plant bug (Lygus rugulipennis) and the alfalfa plant bug (Adelphocoris lineolatus). Since both species prefer to feed on flowering plants, it seems likely that these compounds serve as important stimuli when searching for food. These results are not only scientific novelties for both species, but to my best knowledge, despite the economic importance of the alfalfa plant bug, this is the first report of any behavioral effect of a semiochemical on this species.

In the course of an international cooperation I had the possibility to test the sex pheromone compounds of L. rugulipennis in field experiments. Surprisingly the strong attractive effect generally expected for a sex pheromone was rarely shown in the experiments. For instance in some experiments phenylacetaldehyde, a potential feeding attractant attracted more individuals (even males), than did the pheromone baits. This relatively lesser attractive effect of the sex pheromone baits imply that more complex mechanisms may be involved in sexual communication than previously thought. In the course of my bioacoustic studies, I have discovered for the first time, that plant-transmitted vibrational signals may also play an important role in sexual communication of this species.

In our region it was my privilege to test aphid sex pheromone compounds in field experiments for the first time. These compounds attracted predatory adults of Chrysopa formosa and C. pallens, surprisingly mostly males. Currently there is no obvious explanation for this phenomenon, however it may be hypothesised that there is a possible similarity between the aphid sex pheromone compounds and supposed pheromone compounds of these lacewing species.

As a surprising result, aphid sex pheromones decreased the attraction of common green lacewings (Chrysoperla carnea species-complex) to a floral bait otherwise highly attractive to them. This phenomenon has not been known previously, and is especially interesting, since

aphids provide important and preferred food source to larvae of these species. A possible explanation could be that this effect is not due to the aphid sex pheromone compounds themselves, instead, to their similarity to possible pheromone compounds of other green lacewing (e.g. Chrysopa) species. An other possibility is that as a secondary effect, common green lacewings were affected by the strong smell of Chrysopa lacewings trapped.

Thanks a lot for this information, really surprising results 

May you have a nice day at work.
