The harlequin ladybird, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), is native to Asia but has been intentionally introduced to many countries as a biological control agent of pest insects. In numerous countries, however, it has been introduced unintentionally. The dramatic spread of H. axyridis within many countries has been met with considerable trepidation. It is a generalist top predator, able to thrive in many habitats and across wide climatic conditions. It poses a threat to… 

Life history of the harlequin ladybird, Harmonia axyridis: a global meta-analysis

Results of this meta-analysis support the hypothesis that the life history of the beetle has changed during its invasion into North America and Europe, and highlight differences in development rate that may partially explain the invasive success of H. axyridis.

Habitat Preferences of the Invasive Harlequin Ladybeetle Harmonia axyridis (Coleoptera: Coccinellidae) in the Western Cape Province, South Africa

The native arthropod assemblage responded primarily to season and habitat and secondary to the presence of H. axyridis, which appeared to influence the assemblages composition of other ladybeetles and herbivores.

Harmonia axyridis (Coleoptera: Coccinellidae): Smelling the rat in native ladybird declines

A wider perspective is needed, encompassing other ladybirds, longer timeframes and better comparisons with other (non-ladybird) invasive species to more clearly assess whether H. axyridis really poses as much of a threat as is often proposed.

Predators and parasitoids of the harlequin ladybird, Harmonia axyridis, in its native range and invaded areas

It is concluded that enemy release cannot be excluded as a possible mechanism contributing to the spread and increase of H. axyridis in the early stages of invasion, but adaptation of parasitoids may lead to novel associations which might offset previous effects of enemy release.

Antennal sensory organs and glands of the harlequin ladybird, Harmonia axyridis

Investigations of H. axyridis antennae showed some peculiar characteristics not known in Coccinellidae, such as the concentration of sensory structures at the level of the distal part of the apical antennomere and the discovery of antennal glands associated with it.

Interactions between the Multicolored Asian Lady Beetle Harmonia axyridis and the Parasitoid Dinocampus coccinellae

The parasitoid may play a marginal role in controlling the populations of the Asian lady beetle, without representing a threat to A. bipunctata.

Citizen science reveals the distribution of the invasive harlequin ladybird (Harmonia axyridis Pallas) in Argentina

Citizen science is a valuable tool for mapping invasive alien species in a large country like Argentina, and will help to monitor the continuous expansion of H. axyridis.

The Rare Five-Spot Ladybird Coccinella quinquepunctata (Coleoptera: Coccinellidae) Surviving in an Unstable Habitat

Coccinella quinquepunctata (the five-spot ladybird), was considered extinct in the UK until 1987. Since this time the species is abundant, however, only in very specific habitat in Wales and

Ladybird communities in rural woodlands: Does an invader dominate?

The invasive alien species Harmonia axyridis (Coleoptera: Coccinellidae) was first observed in the UK in 2004. Previous studies have demonstrated the adverse effects on other species of H. axyridis

Native ladybird decline caused by the invasive harlequin ladybird Harmonia axyridis: evidence from a long‐term field study

This study shows a clear change in the ladybird community on lime trees over an 11‐year period in which H. axyridis invaded England.



Predicting the potential geographical distribution of the harlequin ladybird, Harmonia axyridis, using the CLIMEX model

The CLIMEX programme (v2) is used to predict the potential geographical distribution of H. axyridis by means of matching the climate of its region of origin with other regions in the world and taking in account biological characteristics of the species.

Invasion history, habitat preferences and phenology of the invasive ladybird Harmonia axyridis in Belgium

The potential of H. axyridis to disrupt native ladybird assemblages in Belgium is discussed Based on recorded distribution, ecology and phenology, the potential to affect native species is higher for generalist, deciduous and coniferous tree ladybird species than for heathland and wetland specialist species.

Invasions by Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) in the Western Hemisphere: implications for South America.

The history of its invasion in the Western Hemisphere is reviewed, and various factors critical to the future invasion (i.e., arrival, establishment, and spread) of new areas of South America are addressed.

Living with the enemy: parasites and pathogens of the ladybird Harmonia axyridis

An overview of the parasites and pathogens of coccinellids with a particular focus on H. axyridis as a host is provided and it is predicted that H.Axyridis could benefit from both enemy release and EICA within the introduced range but require further empirical evidence.

Harmonia axyridis in Great Britain: analysis of the spread and distribution of a non-native coccinellid

The objective of this study was to quantify and analyse the spread of H. axyridis in its early stages of invasion in Great Britain, and to present evidence of bi-voltinism in the population in 2006.

The invasion history, distribution and colour pattern forms of the harlequin ladybird beetle Harmonia axyridis (Pall.) (Coleoptera, Coccinellidae) in Slovakia, Central Europe

The invasion history and distribution of H. axyridis in Slovakia are discussed with regard to the time sequence of records, rate of spread, altitudinal distribution, anthropogenic dispersal, effective recording, proportion of melanic forms and other relevant aspects associated with the spread of this successful invader.

Harmonia axyridis: What will stop the invader?

The reasons why the species has a high invasiveness and what are the limits to invasion by this species are discussed and the reason for the absence of the predator in the Azores islands is discussed.

Discovery of an alien invasive, predatory insect in South Africa: The multicoloured Asian ladybird beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae)

There is reason to suspect that HA will spread rapidly through much of South Africa and beyond and bring to bear its negative consequences here, and the early detection of this incursion presents a rare opportunity to study an anticipated biological invasion virtually from its beginning.

Ecology and biological control application of multicoloured Asian ladybird, Harmonia axyridis: A review

The ecology of and biological control by multicoloured Asian ladybird beetle, Harmonia axyridis (Pallas) are reviewed and the question on its present position, whether it is a biocontrol agent or pest, is a critical issue and discussed.

The harlequin ladybird (Harmonia axyridis Pallas) in Denmark: spread and phenology during the initial phase of invasion.

Based on the observed phenology and on calculations of thermal sums for complete development, it is suspected that H. axyridis is bivoltine in Denmark with a possible third generation in warm years.
