“…During aggregation, adult H. axyridis show mutual interactions, and should therefore be considered as social aggregators. In addition to the physical contacts between congeners (Durieux et al, 2014a), laboratory assays have shown that chemical markings are involved in this aggregation behavior (Durieux et al, 2012). Non-volatile long-chain hydrocarbons are passively deposited by walking males and females on the surfaces surrounding the aggregation site (Kosaki and Yamaoka, 1996;Durieux et al, 2012).…”

The harlequin ladybird Harmonia axyridis is now established as a model to test hypotheses explaining why some species become successfully invasive, while others, even closely related ones, do not. In this review, we evaluate behavioral and immunological features that may play a role in the invasive performance of this model species. We discuss the behavioral traits and associated semiochemicals that promote the invasive success of H. axyridis. In particular, we consider (1) the aggregative behavior and the particular role of long-chain hydrocarbons; (2) the importance of sex pheromones and non-volatile chemicals in mate location and selection; (3) the use of allelochemicals for prey location; and (4) the nature of chemicals that protect against natural enemies. We also highlight the superior immune system of H. axyridis, which encompasses a broader spectrum of antimicrobial peptides (and higher inducible expression levels) compared with native ladybird beetles such as Adalia bipunctata and Coccinella septempunctata. The chemical defense compound harmonine and the antimicrobial peptides are thought to confer resistance against the abundant microsporidia carried by H. axyridis. These parasites can infect and kill native ladybird species feeding on H. axyridis eggs or larvae, supporting the hypothesis that intraguild predation plays a role in the ability of H. axyridis to outcompete native ladybird species in newly-colonized areas.

“…Lady beetles are no exception. An extensive literature documents the importance of CHC for guiding Harmonia axyridis individuals to overwintering sites, as well as their aggregation behaviour (Durieux et al, 2012(Durieux et al, ,2013(Durieux et al, ,2015(Durieux et al, ,2014. Lady beetles also rely on chemical cues to locate conspecifics and select mates, with long-and short-distance olfactory cues, respectively, being involved (Fassotte et al, 2016).…”

The taste of origin in a lady beetle: do males discriminate between females based on cuticular hydrocarbons?

The Asian lady beetle Harmonia axyridis originates from Asia and has established invasive populations worldwide. Recent population genetic studies trace their invasion routes and demonstrate that bottlenecks in population size have reduced their genetic diversity. Consequently, phenotypical differences are highlighted between native and invasive populations. Among phenotypical traits, cuticular hydrocarbons (CHCs) might reflect the geographical origin of a lady beetle, especially because of their genetic basis. The present study investigates whether (i) the CHC profiles qualitatively and quantitatively differ between females of H. axyridis from native and invasive populations and (ii) males discriminate females from native and invasive populations using CHC profiles. CHCs are solvent‐extracted before being quantified and identified by gas chromatography and mass spectrometry. In total, 17 CHCs are detected from female elytra, including six alkanes, three polyunsaturated and eight monounsaturated alkenes. The total quantity of CHCs differs among the populations, with lady beetles from Tai'an (China) displaying higher CHC concentrations than lady beetles from Gembloux (Belgium) and from Beijing (China) populations. Multivariate analyses detect differences in CHC qualitative profiles, with females from Tai'an being different from the two other populations. Finally, behavioural assays show that females originating from the native Tai'an population are less preferred by males, whereas females from the invasive population are mounted more often. The behavioural assays suggest that CHCs are not involved in discrimination of mating partners based on their origin.

Exclusion cages were used to compare the incidence and severity of feeding injury from brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), on 'Redhaven' peaches, 'Golden Delicious' apples, and 'Smoothee Golden' apples at harvest, following sequential periods of exposure to natural H. halys populations during the 2011 and 2012 growing seasons in Virginia. The fruit used in these experiments were in orchards or on trees that were not managed for H. halys. Treatments were sets of 50 fruit that were always caged, never caged, or exposed during one interval during the fruiting period of peaches and apples in the Mid-Atlantic region of the United States. The cages effectively prevented feeding injury from H. halys. Peaches and apples that were never caged showed the highest percentages of injured fruit at harvest. Exposure treatment had a significant effect on the percentage of fruit showing external injury at harvest in both years for apples and in 2012 for peaches, and a significant effect on the percentage of apples and peaches showing internal injury at harvest in both years. There was no consistent effect of each exposure period on peach injury, but apples exposed during the mid- to latter portion of the season tended to show most injury. Across all exposure periods, more internal than external injuries were recorded at harvest from peaches, while apples tended to have equal or very similar numbers of both kinds of injury. The implications of these results to H. halys management in eastern apple orchards are discussed.
