Evolution in biocontrol strains: insight from the harlequin ladybird Harmonia axyridis. [PDF]
Evol Appl, 2012 After being used as a biocontrol agent against aphids for decades without harmful consequences, the Asian harlequin ladybird Harmonia axyridis has suddenly become an invasive pest on a worldwide scale.

Light Intensity Modulates Locomotor Behavior and Predation in Different Color Morphs of the Harlequin Ladybird, Harmonia axyridis [PDF]
InsectsLight is a fundamental ecological cue for insects, influencing physiological rhythms and behavior. We investigated how varying light intensities affect locomotion and foraging in H. axyridis color morphs, and examined the role of visual opsins.

Fifty Shades of the Harlequin Ladybird and a Sexually Transmitted Fungus. [PDF]
J Insect Sci, 2019 AbstractThe ectoparasitic fungus Hesperomyces virescens was studied on its invasive host, the harlequin ladybird Harmonia axyridis, in the Czech Republic. A primary aim was to examine the relationship between fungal infection and elytral coloration of the ladybird. Furthermore, the role of host sex and mating status of females were analyzed. Beetles (n

Cannibalism in invasive, native and biocontrol populations of the harlequin ladybird. [PDF]
BMC Evol Biol, 2014 Cannibalism is widespread in both vertebrates and invertebrates but its extent is variable between and within species. Cannibalism depends on population density and nutritional conditions, and could be beneficial during colonisation of new environments. Empirical studies are needed to determine whether this trait might facilitate invasion of a new area

Phylogenetic Analyses of True Ladybirds (Coleoptera: Coccinellidae: Coccinellini) Reveal Directionality in Diet Evolution and Support a Boreotropical Origin of the Tribe. [PDF]
Ecol EvolA newly generated large‐scale molecular phylogeny of true ladybirds (Coccinellini) clarifies their evolutionary relationships and supports a boreotropical origin in the Paleocene, with multiple independent southward dispersals. Ancestral diet reconstructions suggest an initial specialization on aphids, followed by expansions in host range and ...
