Juvenile hormone regulates the photoperiodic plasticity of elytra coloration in a ladybird Harmonia axyridis
<p><span>Many animals, including insects, exhibit plasticity of body color in response to environmental changes</span><span>. Varied expression of c</span><span>arotenoids, major cuticle pigments, significantly contributes to body color flexibility. However, the molecular mechanisms by which environmental cues regulate carotenoid expression remain largely unknown. In this study, we used the ladybird <em>Harmonia axyridis</em> as a model to investigate the photoperiodic-responsive plasticity of elytra coloration and its endocrine regulation. It was found that <em>H. axyridis</em> females under long-day conditions develop elytra that are much redder than those under short-day conditions, resulting from the differential accumulation of carotenoids. Exogenous hormone application and RNAi-mediated gene knockdown indicate that carotenoid deposition was directed through the juvenile hormone (JH) receptor-mediated canonical pathway. Moreover, we characterized an SR-BI/CD36 (SCRB) gene <em>SCRB10</em> as the carotenoid transporter responding to JH signaling and regulating the elytra coloration plasticity. Taken together, we propose that JH signaling transcriptionally regulates the carotenoid transporter gene for the photoperiodic coloration plasticity of elytra in the beetles, which reveals a novel role of the endocrine system in the regulation of carotenoid-associated animal body coloration under environmental stimuli.</span></p>

Data from: Complementarity of statistical treatments to reconstruct worldwide routes of invasion: the case of the Asian ladybird Harmonia axyridis
Inferences about introduction histories of invasive species remain challenging because of the stochastic demographic processes involved. Approximate Bayesian computation (ABC) can help to overcome these problems, but such method requires a prior understanding of population structure over the study area, necessitating the use of alternative methods and an intense sampling design. In this study, we made inferences about the worldwide invasion history of the ladybird Harmonia axyridis by various population genetics statistical methods, using a large set of sampling sites distributed over most of the species' native and invaded areas. We evaluated the complementarity of the statistical methods and the consequences of using different sets of site samples for ABC inferences. We found that the H. axyridis invasion has involved two bridgehead invasive populations in North America, which have served as the source populations for at least six independent introductions into other continents. We also identified several situations of genetic admixture between differentiated sources. Our results highlight the importance of coupling ABC methods with more traditional statistical approaches. We found that the choice of site samples could affect the conclusions of ABC analyses comparing possible scenarios. Approaches involving independent ABC analyses on several sample sets constitute a sensible solution, complementary to standard quality controls based on the analysis of pseudo-observed datasets, to minimize erroneous conclusions. This study provides biologists without expertise in this area with detailed methodological and conceptual guidelines for making inferences about invasion routes when dealing with a large number of sampling sites and complex population genetic structures.
Data from: The evolution of chemical defenses along invasion routes: Harmonia axyridis Pallas (Coccinellidae: Coleoptera) as a case study
The Evolution of Increased Competitive Ability (EICA) hypothesis (Blossey & Nötzold, 1995) postulates that escaping from coevolved enemies increases invaders fitness by energy reallocation from defenses and immunity to growth and reproduction. In this context, we evaluated the evidence of evolutionary change in invasive populations of Harmonia axyridis Pallas (Coccinellidae: Coleoptera). We measured egg defenses – cocktail of hydrocarbons on the egg's surface flagging egg toxicity, and the concentration of the main alkaloid harmonine - in individuals from three populations along the invasion route (Japan: native, USA: introduced more than 30 years ago, South Africa: introduced in the early 2000s) in a common garden experiment. Our results support the EICA hypothesis: we found changes along the invasion route in the profiles of the hydrocarbons coating the eggs' surface, and a decrease in the concentration of harmonine in eggs from the most recent invasive South African population compared to the long established in the USA and the native Japanese ones.
Data from: Rapid increase in dispersal during range expansion in the invasive ladybird Harmonia axyridis
The evolutionary trajectories associated with demographic, genetic and spatial disequilibrium have become an issue of growing interest in population biology. Invasive species provide unique opportunities to explore the impact of recent range expansion on life-history traits, making it possible to test for a spatial arrangement of dispersal abilities along the expanding range, in particular. We carried out controlled experiments in laboratory conditions to test the hypothesis of an increase in dispersal capacity with range expansion in Harmonia axyridis, a ladybird that has been invading Europe since 2001. We found a marked increase in the flight speed of the insects from the core to the front of the invasion range in two independent sampling transects. By contrast, we found that two other traits associated with dispersal (endurance and motivation to fly off) did not follow the same spatial gradient. Our results provide a striking illustration of the way in which predictable directional genetic changes may occur rapidly for some traits associated with dispersal during biological invasions. We discuss the consequences of our results for invasion dynamics and the evolutionary outcomes of spatially expanding populations.

Mutant Harmonia axyridis raw sequencing data of CRISPR/Cas9 induced mutations in the genes laccase2 and scarlet
<p><em>Harmonia axyridis</em> (Pallas), commonly known as the Asian lady beetle, is a native insect species of Asia that has been intentionally introduced to various regions for biocontrol purposes. However, its widespread presence beyond its original release sites suggests a high degree of invasiveness. In this study, we utilized the CRISPR-Cas9 approach to achieve precise genome editing in <em>H. axyridis</em>. Specifically, we targeted two genes in <em>H. axyridis</em>, <em>laccase2</em> and <em>scarlet</em>, knockdown of which orthologs in other insects showed visible phenotypic changes. The knockout <em>laccase2</em> resulted in an early-detectable phenotype but also in lethality. However, we successfully established a viable and genetically stable mutant colony by disrupting the <em>scarlet </em>gene, resulting in beetles with white eyes. Our findings contribute to the expanding knowledge of genetic manipulation in <em>H. axyridis</em> and provide insights into its potential for future research and practical applications for biocontrol and invasive species management.</p>
