متن کاملCan things get worse when an invasive species hybridizes? The harlequin ladybird Harmonia axyridis in France as a case study
So far, only a few studies have explicitly investigated the consequences of admixture for the adaptative potential of invasive populations. We addressed this question in the invasive ladybird Harmonia axyridis. After decades of use as a biological control agent against aphids in Europe and North America, H. axyridis recently became invasive in four continents and has now spread widely in Europe...
متن کاملEvolution in biocontrol strains: insight from the harlequin ladybird Harmonia axyridis
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. We investigate the impact of captive breeding on several traits of this ladybird such as genetic diversity, fecundity, survival and pathogen resistance. We conducted an experiment in the laborato...
متن کاملInvestigating the genetic load of an emblematic invasive species: the case of the invasive harlequin ladybird Harmonia axyridis
Introduction events can lead to admixture between genetically differentiated populations and bottlenecks in population size. These processes can alter the adaptive potential of invasive species by shaping genetic variation, but more importantly, they can also directly affect mean population fitness either increasing it or decreasing it. Which outcome is observed depends on the structure of the ...
متن کاملRecord of the invasive alien ladybird Harmonia axyridis (Coleoptera, Coccinellidae) from Kenya
The biological control agent and alien invasive ladybird Harmonia axyridis (Pallas, 1773) was recorded for the first time in Kenya, and in equatorial Africa, in 2010.
