“…However, other parasites may also experience similar novel host driven expansions. Recently, H. axyridis was recorded as a host of the ectoparasitic mite C. hippodamiae in North America (Mississippi, USA) (Riddick, 2010) and Europe (northcentral Poland) (Rhule et al, 2010). Our unpublished data indicate that this host-parasite association is also quite common in other regions in Poland.…”

“…The association between Harmonia axyridis and Hesperomyces virescens is an example of the latter, less frequent, process. The case described above can be included with an increasing body of evidence that the invasive populations of the harlequin ladybird are not only susceptible to some native parasites such as H. virescens, the mite Coccipolipus hippodamiae (McDaniel & Morrill) (Rhule et al, 2010;Riddick, 2010) and allantonematid nematodes (Harding et al, 2011;Roy et al, 2011b;Poinar & Steenberg, 2012), but also contribute to their dispersal, increase in prevalence and intensity of infection.…”

Abstract.Hesperomyces virescens is an ectoparasite of some Coccinellidae, which until the mid-1990s was relatively rarely only reported from warm regions in various parts of the world. Analysis of the host and distribution data of H. virescens recorded in the Western Palaearctic and North America reveals several trends in the occurrence and abundance of H. virescens: (1) it has recently been much more frequently recorded, (2) most of the recent records are for more northerly (colder) localities than the early records and (3) the recent records are mostly of a novel host, the invasive harlequin ladybird (Harmonia axyridis). While in North America H. virescens is almost exclusively found on H. axyridis, all European records of this association are very recent and still less numerous than records of Adalia bipunctata as a host. However, based on a relatively few published cases of the H. axyridis-H. virescens association in Europe and the case described in this paper, it is clear that the harlequin ladybird is currently the main host of this parasite. These changes in the abundance and geographical distribution of H. virescens are probably linked to some features of H. axyridis, such as its abundance, multivoltinism with overlapping generations, high level of promiscuity and overwintering in mass aggregations. The occurrence of these features in one species may make it especially suitable for H. virescens and other parasites that require close contact of host individuals for efficient transmission. Indeed, some of the data indicate that parasites other than H. virescens, like the podapolipid mite Coccipolipus hippodamiae and allantonematid nematodes of the genus Parasitylenchus may also heavily parasitize H. axyridis. We hypothesize that the acquisition of H. axyridis as a host by H. virescens, C. hippodamiae and Parasitylenchus spp. may have further consequences for the abundance and distribution of these parasites, including the expansion of their ranges to other continents colonized by invasive populations of this ladybird and areas in Asia where H. axyridis is native.

“…One such natural enemy in Europe may be the sexually transmitted mite Coccipolipus hippodamiae (McDaniel and Morrill), a species first documented in North America to infect H. axyridis under field conditions (Riddick 2010). Infection of H. axyridis by this mite, as now confirmed in the field in Poland and likely arising from interspecific mating with infected indigenous ladybirds, results in female sterility (Rhule et al 2010). Infection by the mite of H. axyridis males in natural populations in North America was associated with intensity of infection by Hesperomyces virescens Thaxter (Riddick 2010), a parasitic fungus found to attack H. axyridis (even more so than co-occurring indigenous ladybirds) in eastern North America (Riddick and Schaefer 2005;Harwood et al 2006).…”

“…As illustrated by mites and ladybirds (Rhule et al 2010), sharing of natural enemies with invasive alien ladybirds sometimes can have negative effects on indigenous ladybirds. But a positive rather than negative effect can arise if such sharing results in dilution of attack on indigenous ladybirds.…”

Invasions by ladybugs, ladybirds, and other predatory beetles

2011

Species of predatory Coleoptera have become abundant in new geographic regions recently, raising concerns for invaded ecosystems. We address this topic by focusing on invasive alien ladybird beetles (Coccinellidae; known also as ladybugs). Humans appear directly or indirectly responsible for all or most ladybird invasions. Factors hypothesized to have promoted ladybird invasions include genetic diversity (e.g., for polymorphism), phenotypic plasticity, adaptation and genetic shift, generalized diet and habitat preferences, flexible life history and reproduction, large body size, and release from enemies. Factors such as climate, habitat and prey availability, and biotic resistance may sometimes prevent or slow ladybird invasions. Indigenous species (e.g., herbivores) may suffer from invasions, and biological control programs may be affected. Species of indigenous ladybirds throughout the world are reported to have declined in abundance following ladybird invasions, with increased competition and/or intraguild predation most often hypothesized or inferred. Similar recent studies especially of ground beetles (Carabidae) also make clear the potential of invasive alien predatory Coleoptera to disrupt invaded natural and agricultural ecosystems.
