Spiroplasma infection in Harmonia axyridis - Diversity and multiple infection

open access: yesPLOS ONE, 2018
The heritable endosymbiotic bacterium Spiroplasma is found in the harlequin ladybird Harmonia axyridis. The proportion of beetles infected with Spiroplasma in different native H. axyridis populations varies from 2% to 49%. We investigated the polymorphism of Spiroplasma strains in samples from individual beetles from Kyoto, Vladivostok, Troitsa Bay ...

Effects of starvation on the carbohydrate metabolism in Harmonia axyridis (Pallas)

open access: yesBiology Open, 2017
Trehalose plays an important role in energy storage, metabolism, and protection from extreme environmental conditions in insects. Trehalose is the main ‘blood’ sugar in insects, and it can be rapidly used as an energy source in times of need. To elucidate the mechanisms of the starvation response, we observed the effects of starvation on trehalose and ...
