Responses of tree sparrow \kur{Passer montanus} to harlequin ladybird \kur{Harmonia axyridis}.

, 2014
Responses of tree sparrow (Passer montanus) to aposematic harlequin ladybird were studied in laboratory tests. Four age classes of tree sparrows were confronted with natural and brown painted ladybirds of succinea ...

Has the arrival of the harlequin ladybird, Harmonia axyridis, contributed to changes in the trends of British hoverfly and ladybird species?

ARPHA Conference Abstracts
Harmonia axyridis , the harlequin ladybird, is an invasive non-native species now found in many countries around the world. First recorded in Britain in 2004, it spread rapidly across the country and has become the most abundant ladybird species in ladybird assemblages, particularly in urban habitats.

Access to harmonine, a chemical weapon of ladybird beetles

, 2014
The synthesis of harmonine, a defense alkaloid from the harlequin ladybird is reported by three different routes. The preparation of several new analogs with the same molecular weight and the decoration of gold nanoparticles with harmonines are also part

The genomic basis of colour pattern polymorphism in the harlequin ladybird

, 2018
Many animal species are comprised of discrete phenotypic forms. Understanding the genetic mechanisms generating and maintaining such phenotypic variation within species is essential to comprehending morphological diversity. A common and conspicuous example of discrete phenotypic variation in natural populations of insects is the occurrence of different

New data on ladybird beetles (Coleoptera: Coccinellidae) of Wigry National Park [PDF]

, 2016
Ladybird beetles were surveyed in 2014-2016 in Wigry National Park (NE Poland). Thirty three species were recorded. The most abundant were Subcoccinella vigintiquatuorpunctata (20% of all ladybird individuals) and Coccinella quinquepunctata (17% of all ...

Unraveling genetic load dynamics during biological invasion: insights from two invasive insect species

Peer Community Journal
Many invasive species undergo a significant reduction in genetic diversity, i.e. a genetic bottleneck, in the early stages of invasion. However, this reduction does not necessarily prevent them from achieving considerable ecological success and becoming ...

Investigating ladybird alkaloids as potential leads for novel insecticides [PDF]

, 2016
Ladybird beetles produce a range of alkaloid compounds which are found a high concentration in the haemolymph and released in response to perceived threat. These alkaloids are thought to function as agents of chemical defence and a small number have been
