Combinations of (E)-2-hexenal diethyl acetal, racemic α-terpineol or linalool, with or without benzyl alcohol incorporated into polyvinyl chloride attracted wasps in the Vespula vulgaris species group, including the Eastern, Vespula maculifrons (Buysson), and German, V. germanica (F.), yellowjackets. (E)-2-Hexenal diethyl acetal degrades to release (E)-2-hexenal (the active attractant form) and ethanol, which may help kill yellowjackets caught in the water inside the traps used for testing. Combining the (E)-2-hexenal diethyl acetal/α-terpineol or linalool mixtures with another blend previously reported as attractive to yellowjackets (acetic acid/isobutanol) synergistically attracted the Eastern yellowjacket. It is hypothesized that the synergistic attraction is a result of combining volatile chemicals associated with carbohydrate feeding (acetic acid/isobutanol) and volatiles associated with foraging for insect prey (hexenal/α-terpineol or linalool).

Invasion facilitation, whereby one species has a positive effect on the establishment of another species, could help explain the rapid colonisation shown by some freshwater invasive species, but the underlying mechanisms remain unclear. We employed two-choice test arenas to test whether the presence of zebra mussel (Dreissena polymorpha) could facilitate the establishment of the killer shrimp (Dikerogammarus villosus). Killer shrimp preferred to settle on mats of zebra mussel, but this was unrelated to mat size, and was not different from attraction shown to artificial grass, suggesting that zebra mussel primarily provides substrate and refuge to the killer shrimp. Killer shrimp were strongly attracted to water scented by zebra mussel, but not to water scented by fish. Chemical attraction to the zebra mussel’s scent did not differ between sympatric and allopatric populations of killer shrimp, suggesting that chemical attraction is not an acquired or learned trait. Our study shows, for the first time, chemical attraction between two highly invasive freshwater species, thereby providing a plausible mechanism for invasion facilitation. This has implications for managing the spread of killer shrimp, and perhaps other freshwater invasive species, because chemical attraction could significantly increase establishment success in mutualistic systems. Failure to consider invasion facilitation may underestimate the risk of establishment, and likely also the impact of some aquatic invaders.

Abstract The present study was undertaken to verify ancient data in the literature on ovipositional preference of the cuttlefish Sepia officinalis for the terrestrial plant Pistacia lentiscus (mastic tree). -Adult specimens of Sepia were placed in basins together with aerial parts not only of P. lentiscus, but also of Artemisia arborescens, Centaurea alba var. deusta, Quercus ilex and Laurus nobilis. The egg masses deposited on the plants were quantified on a daily basis during the 16 day observation period. By far the largest amounts of eggs were found attached to the stems and petioles of P. lentiscus (51.8%), but Q. ilex and A. arborescens also scored high as ovipositional host plants (23.1 and 20.2% respectively). L. nobilis and C. alba var. deusta ranked very low (3.6 and 1.3% respectively). Considering the extremely divergent shape of the three preferred oviposition substrates, which excludes affinity for a uniform type of plant, the possibility of chemical attraction cannot be ruled out.
