“…The consequences of these novel interactions depend on the acceptability and suitability of the herbivore as host or prey. Attractive but toxic preys or acceptable hosts that do not support adult parasitoid development may represent dead ends for the natural enemies and thus have negative consequences on their populations8910. In contrast, a well-suited and abundant novel food source will allow the natural enemies to thrive and their enhanced populations may even reduce native herbivore populations via apparent competition1112.…”

Since its introduction into Europe the invasive Drosophila suzukii has established and spread widely, thereby entering habitats populated by native Drosophila species and their natural enemies. The highly prolific D. suzukii will likely interact with these species as a competitor, host or prey. To investigate potential interactions of D. suzukii with parasitoids, a field survey was conducted across several fruit-growing regions in Switzerland in two consecutive years. Eight species of hymenopteran parasitoids were collected using D. melanogaster as sentinel hosts in field-traps. Parasitoid capture was much higher in 2015 than in 2014 and varied among regions, time of the growing season, and habitat type. Laboratory no-choice assays with the field-collected species demonstrated that the larval parasitoids Asobara tabida, Leptopilina boulardi, and L. heterotoma could not use D. suzukii for reproduction, although the latter two reduced the number of emerging D. suzukii. In contrast, the pupal parasitoids Pachycrepoideus vindemmiae, Trichopria drosophilae, Vrestovia fidenas and Spalangia erythromera all developed with D. suzukii as hosts. Regional differences between strains were generally not evident, with the exception of two T. drosophilae strains that differed in parasitization rate. Thus, native parasitoids may interact with D. suzukii and should be regarded when implementing pest control measures.

“…As U. nigrotuberculatum is unsuitable for their offspring (Barry & Ohno, 2015), they thus fall into an ecological trap. Because solidago patches infested with U. nigrotuberculatum occur naturally in early summer, when other suitable habitats such as vetch patches infested with aphids such as M. crassicauda, Aphis craccivora Koch, and A. pisum are depleted, adult coccinellids may immigrate to solidago patches.…”

“…The reason for this negligence is centered on the tenet of the 'life-dinner' principle (Dawkins & Krebs, 1979), which purports that the selection pressure on prey is stronger than on predators. Barry & Ohno (2015) reported high performance of C. septempunctata and P. japonica on M. crassicauda, which is a main prey in spring, when these lady beetles produce their first brood after overwintering. This could be the case for the interaction between aphidophagous coccinellids and the goldenrod aphid in Japan.…”

“…Since its arrival, U. nigrotuberculatum has heavily infested solidago patches and it has become the main herbivore on solidago. It is a noxious prey, as it causes high larval mortality and delayed development of Coccinella septempunctata bruckii Mulsant, Propylea japonica (Thunberg) (Barry & Ohno, 2015), and Harmonia axyridis (Pallas) (all Coleoptera: Coccinellidae) (Kamo & Tokuoka, 2011). The goldenrod aphid is a large red aphid that emerges from overwintered eggs in early March and disappears by early August.…”

Generalist aphidophagous coccinellids have to cope with novel prey aphids in environments that are changing rapidly because of anthropogenic activity. The goldenrod aphid, Uroleucon nigrotuberculatum (Olive) (Hemiptera: Aphididae), is a noxious prey, which was recently introduced into Japan. It is a major prey for the native Japanese predators Coccinella septempunctata bruckii Mulsant and Propylea japonica (Thunberg) (both Coleoptera: Coccinellidae) in early summer on patches of solidago, Solidago altissima L. (Asteraceae). Prey preference of these coccinellids between this aphid and a native suitable prey aphid, Megoura crassicauda Mordvilko (Hemiptera: Aphididae), as well as their foraging behavior were studied for a better understanding of the negative impacts of the noxious novel aphid. Coccinella septempunctata initially preferred the novel prey, but later switched to the native prey, M. crassicauda; P. japonica had no preference for either prey. Feeding time of the first instars of C. septempunctata on U. nigrotuberculatum was significantly longer than that of P. japonica. The foraging bouts of fourth instars of C. septempunctata were significantly longer on U. nigrotuberculatum than on M. crassicauda, whereas only the feeding time of fourth instars of P. japonica on U. nigrotuberculatum was significantly longer than on M. crassicauda. Both coccinellids consumed less of U. nigrotuberculatum than of M. crassicauda. Thus, solidago patches infested by U. nigrotuberculatum may present an ecological trap, especially for C. septempunctata.

“…The goldenrod aphid, Uroleucon nigrotuberculatum (Olive), was unintentionally introduced into Japan from North America about 40 years ago (Sugimoto & Matsumoto 2000). Recent studies suggest that this aphid is a noxious prey for Japanese native aphidophagous lady beetles (Coleoptera: Coccinellidae): it delays their larval development, causes very high larval mortality and inhibits adult reproduction of Harmonia axyridis (Pallas) (Kamo & Tokuoka 2011), Coccinella septempunctata bruckii Mulsant and Propylea japonica (Thunberg) (Barry & Ohno 2015). In the laboratory and in the field, we observed that many lady beetle larvae and adults preying on the goldenrod aphid were smeared with red secretions, and we assumed that the aphid actively secretes these droplets as a physical defense against the predators.…”

Aphids have evolved various defense strategies against natural enemies, including secretions from their cornicles. We assessed the defensive function of cornicle secretions by the goldenrod aphid, Uroleucon nigrotuberculatum (Olive), against larvae of the lady beetles Coccinella septempunctata bruckii Mulsant and Propylea japonica (Thunberg) (Coleoptera: Coccinellidae). The aphid secreted red droplets from its cornicles when attacked by the larvae. Two‐thirds of the C. septempunctata bruckii larvae and 46.7% of the P. japonica larvae that preyed on the aphids died before reaching the pre‐pupal stage. The secretions caused molting failure when smeared on the larvae's heads or glued to the larvae's mouthparts, killing 56.7% of C. septempunctata bruckii larvae and 36.7% of P. japonica larvae. Second instar larvae were affected most. About 40% of third and fourth instar larvae of C. septempunctata bruckii vomited soon after ingesting the aphids. In the field, up to 40% of first and second instar larvae were smeared with red secretions. Our results show that these cornicle secretions are an effective and active defense against earlier instars of coccinellid larvae.
