“…While, as previously stated, H. axyridis showed high fecundity, other studies demonstrated similar or lower fecundity than indigenous species (Bazzochi et al 2004;Lanzoni et al 2004;Michaud and Olsen 2004;Soares et al 2004). For example, in Italy, the mean fecundity of H. axyridis (783.8 eggs per female) was only slightly higher than an indigenous species, A. bipunctata (720.2 eggs per female) (Bazzochi et al 2004).…”

“…In order to face food scarcity and unfavourable weather, most temperate coccinellid do have an obligatory diapause (Dixon 2000;Hodek and Honȇk 1996). Harmonia axyridis has a true and obligatory diapause (Sakurai et al 1992), after a period of feeding and reproductive activity, somewhere from April to October (Ongagna et al 1993;LaMana and Miller 1996;Katsoyannos et al 1997;Bazzochi et al 2004). Temperature, photoperiod and scarcity of food are key factors for the induction of the coccinellid diapause.…”

In recent years Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) has become a very popular insect among biological control practitioners and scientists, not only for its potential to be an efficient biological control agent but also because it is considered invasive. Individuals of this species were deliberately introduced into several countries for biological control of different arthropods pests. However the predator itself became an invasive species, affecting the dynamics and composition of several guilds through direct or indirect interactions with established species, including intraguild predation. In this paper we discuss the reasons why the species has a high invasiveness and what are the limits to invasion by this species. It is not clear if the invasiveness of the beetle is linked to its biological, ecological and behavioural abilities, or to other factors such as invasibility and interactions between the invaders, the noninvaders, and the habitat, which may in part explain the reasons of its success and help us to answer the question ''what will stop the invader?'' We also discuss the reason for the absence of the predator in the Azores islands. Despite the intentional introduction of H. axyridis in the Azores and the high number of individuals released, there are no records of this species in the wild, despite recent extensive sampling effort. In this paper we discuss the reasons for the apparent failure or the delay in establishment of the predator. One factor which may hamper the establishment of H. axyridis in some of the Azores islands is the absence of winter

“…However, undocumented commercial releases, unintentional introductions, and unaided dispersal capacity (i.e., flight) have certainly contributed to the extent of its invasion. Records exist of H. axyridis being intentionally introduced to North America (Gordon 1985), Europe (Garcia 1986, Ferran et al 1996, Hodek & Honì k 1996, Katsoyannos et al 1997, Trouve et al 1997, Buzzocchi et al 2004 (Fig. 1).…”

Invasões de Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) no Hemisfério Ocidental: Implicacões para a América do Sul RESUMO -A joaninha, Harmonia axyridis (Pallas), nativa da Ásia, foi recentemente detectada na América do Sul depois de ter invadido a América do Norte e Europa. Essa joaninha é um predador voraz, e portanto, popular e eficaz no controle biológico. Infelizmente, H. axyridis também está relacionada a impactos nocivos (ex., como peste residencial e de frutas temperadas e ameaça a organismos não-alvos). Para fazer prever os possíveis impactos de H. axyridis na América do Sul, a história da sua invasão no Hemisfério Ocidental foi revisada e os vários fatores críticos para futuras invasões (isto é, chegada, estabelecimento e disseminação) em novas áreas da América do Sul foram discutidos. A possibilidade de introduções contínuas de H. axyridis na América do Sul parece alta devido a sua popularidade como agente de controle biológico e através de introduções acidentais. Seu estabelecimento também parece possível em extensas regiões da América do Sul. A similaridade climática com a região nativa sugere que o estabelecimento é possível na região sul da América do Sul. Porém, similaridade de hábitat com a região nativa sugere que o estabelecimento seja mais adequado na região norte da América do Sul. Além disso, a disponibilidade da presa não deve ser um fator limitante para o estabelecimento desse predador. Após o estabelecimento, H. axyridis pode se disseminar pelo próprio vôo e por meios associados ao homem. Concluindo, a invasão de H. axyridis em novas áreas do continente sul-americano é provável. (Colunga-Garcia & Gage 1998, Brown & Miller 1998, Michaud 2002b, Alyokhin & Sewell 2004, Saini 2004, which may be partly due to intraguild predation (e.g., Cottrell & Yeargan 1998, Michaud 2002b, Cottrell 2004, Yasuda et al. 2004. In addition, H. axyridis may impact populations of the monarch butterfly, Danaus plexippus (Koch et al. 2004c, in press b). Second, H. axyridis can be a pest of fruit production (Koch et al. 2004a), particularly as a contaminant during wine production (Pickering et al. 2004, Galvan et al. 2006. Third, H. axyridis can be a nuisance to humans. It can become a household pest when it seeks shelter from winter in homes and other structures (Nalepa et al. 2004(Nalepa et al. , 2005. Once on or in a home, massive aggregations of H. axyridis are a nuisance to homeowners (Nalepa et al. 2004, Huelsman & Kovach 2004 and can cause allergic reactions in humans (Ray & Pence 2004). Similarly, H. axyridis can form autumn aggregations in bee hives, where it apparently does not harm the bees, but is a nuisance to the bee keepers (Caron 1996).The geographic range and impacts (both positive and negative) of H. axyridis are expanding rapidly. Currently, this coccinellid is widely established in North America Can we use what we have learned from the invasion of H. axyridis in North America to predict implications for South America? In this paper, we provide a review of the literature on the histor...

“…The Belgian company Biobest and the Dutch company Koppert Biosystems started to sell H. axyridis (produced by Biotop) in 1995 and 1996, respectively (Kabiri 2006). Interestingly, this predator, while released in Italy and southern France, does not seem to have established and created problems there in spite of predictions on its establishment potential in that region in a later period (Iperti and Bertrand 2001;Bazzocchi et al 2004). In Greece (Katsoyannos et al 1997) the establishment potential was considered low in citrus orchards, but no observations where made at that time outside the release area.…”

From Biological Control to Invasion: The Ladybird Harmonia Axyridis as a Model Species

In this paper, we summarize the international situation with respect to environmental risk assessment for biological control agents. Next, we apply a recently designed, comprehensive risk evaluation method consisting of a stepwise procedure to evaluate the environmental risks of Harmonia axyridis in Northwest Europe. This resulted in the very clear conclusion that H. axyridis is a potentially risky species for Northwest Europe, because it is able to establish, it has a very wide host range including species from other insect orders and even beyond the class of Insecta, it may feed on plant materials, it can cover large distances ([50 km per year), it does move into non-target areas, it may attack many non-target species including beneficial insects and insects of conservation concern, its activities have resulted in the reduction of populations of native predators in North America, it is known as a nuisance in North America and recently also in Northwest Europe, and it may develop as a pest of fruit in North America. Considering the H. axyridis case, current knowledge would lead to the conclusion that, although the predator is capable to effectively control several pest species, its risks are manifold and it should, thus, not have been released in Northwest Europe. At the time of the first releases in Nortwest Europe in 1995, the available scientific literature made clear that H. axyridis is a large sized polyphagous predator and has a great reproductive capacity in comparison with other ladybird beetles, and that there was a need to study non-target effects because of its polyphagous behaviour. In retrospect, this information should have been sufficient to reject import and release of this species, but it was apparently ignored by those who considered release of this predator in Northwest Europe. The case of Harmonia releases in Northwest Europe underlines that there is an urgent need for harmonized, world-wide regulation of biological control agents, including an information system on risky natural enemy species.
