No bioaccumulation of Cry protein in the aphidophagous predator Harmonia axyridis

Environmental Toxicology and Pharmacology, 2023
The uptake of insecticidal Cry1Ab from genetically engineered (GE) maize, via herbivore Rhopalosiphum padi, to a predator Harmonia axyridis and its potential intergenerational transfer were investigated. Cry1Ab concentration was found to be 400-fold lower in R. padi compared to GE maize, and more than two-fold lower in H. axyridis.

Winter survival of Harmonia axyridis in The Netherlands

Biological Control, 2012
Abstract Since the establishment of Harmonia axyridis in Europe, populations of native ladybirds have decreased. Overwintering survival is one of the aspects of the biology of H. axyridis that may contribute to its firm establishment in and invasion of a new area. In this study winter survival of five wild H.

Parasites of Harmonia axyridis: current research and perspectives

BioControl, 2016
Harmonia axyridis (Coleoptera: Coccinellidae) has been introduced widely for biological control of agricultural pests. Harmonia axyridis has established in four continents outside of its native range in Asia and it is considered an invasive alien species (IAS).

Harmonia axyridis ladybug invasion and allergy

Allergy and Asthma Proceedings, 2008
Beginning in 1916 Harmonia axyridis, an orange/red lady beetle with variable black spotting, was imported into the United States from Asia. This agricultural pest-control predator established independent feral populations in North America by 1988. Subsequently, Harmonia axyridis has become a pest to homeowners and various horticultural enterprises ...

Cold tolerance of the harlequin ladybird Harmonia axyridis in Europe

Journal of Insect Physiology, 2010
As an essential aspect of its invasive character in Europe, this study examined the cold hardiness of the harlequin ladybird Harmonia axyridis. This was done for field-collected populations in Belgium overwintering either in an unheated indoor or an outdoor hibernaculum. The supercooling point, lower lethal temperature and lower lethal time at 0 and -5

A natural flightless mutation in the ladybird, Harmonia axyridis

Entomologia Experimentalis et Applicata, 2000
AbstractA homozygous flightless strain, obtained by selection from a laboratory population of Harmonia axyridis Pallas (Coleoptera, Coccinellidae), has been reared under controlled conditions since 1982 after sampling in China. The adults of this flightless strain have normal elytra and wings but drop almost vertically when they attempt to fly.

Locomotor Behavior of Flightless Harmonia axyridis Pallas (Col., Coccinellidae)

Journal of Insect Behavior, 1999
To improve the efficiency of the ladybeetle Harmonia axyridis as a biological control agent against aphids, a flightless population was produced by feeding adults with a mutagen and selecting their progeny for non-flying but otherwise morphologically normal individuals.

The occurrence of ladybug Harmonia axyridis in Croatia

Glasilo biljne zaštite, 2010
Božja ovčica Harmonia axyridis Pallas ili azijska božja ovčica introducirana je u SAD i Kanadu u prošlom stoljeću, a od 1995. godine u Europu s ciljem biološkog suzbijanja lisnih uši. U Europi se brzo širila tako da je utvrđena u više zemalja od Švedske pa sve do Francuske. U našem okruženju pronađena je u Italiji, Češkoj i Grčkoj.
