“…To improve their survival during winter, H. axyridis feeds on sugar-containing fruits like apples, pears or grapes in late autumn (Koch, 2003;Lucas et al, 2007b;Galvan et al, 2008). In the case of grapevines, insects could be harvested with the fruit and during the process beetles release haemolymph containing substances that can alter the smell and taste of wine (see Pickering et al, 2004).…”

The multicoloured Asian ladybeetle, Harmonia axyridis (Pallas), an invasive biocontrol agent introduced in North and South America, as well as in Europe for aphid control, drastically affected assemblages of native coccinellid species, local communities and people. Although the insect is common in several European countries and it was released in Spain for aphid control in 1995, no evidence of population establishment has been reported until 2011. In the present paper, 1) we summarize the records of the invasive ladybeetle in Spain and provide numerous new mentions, and 2) we follow for the first time an overwintering aggregation from autumn to spring and characterize some individual features which allow us to determine its phenology of the establishment and spreading. The results establish clearly that: 1) H. axyridis is (until now) restricted to Catalonia (NE Spain) but the invading process is in progress and the insect is able to occupy different habitats; 2) the ladybeetle overwinters successfully in Spain without significant natural mortality or parasitism; 3) the form succinea represents 73-81% of the overwintering individuals, and 4) the invasion takes probably its origin from Southern France. The potential impact of the invasion by H. axyridis in Spain is discussed.

“…Its propensity to aggregate in homes to overwinter (and associated issues of reflex bleeding, biting behavior, and triggering of allergies), and its proclivity in late summer to feed on fruits (e.g., vineyard grapes) further cemented its designation as invasive (Koch and Galvan 2008). Concerns particularly over harmful effects on indigenous species diversity have similarly prompted identification of additional alien ladybird species as invasive or potentially so (e.g., Propylea quatuordecimpunctata L.; Lucas et al 2007;Finlayson et al 2008).…”

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.

“…This is the case with C. septempunctata and H. axyridis, which are most abundant in herbaceous and arboreal habitats, respectively. However, despite occurring in many semi-natural and natural habitats in their invaded ranges, C. septempunctata and H. axyridis, as well as the successful A. bipunctata and P. quatuordecimpunctata, tend to be abundant in agricultural habitats and urban landscapes (e.g., Lucas et al, 2007;Brown et al, 2008;Roy and Migeon, 2010;Evans et al, 2011). In the USA, H. axyridis became a dominant species in agricultural landscapes, thriving in disturbed and manmade habitats such as orchards and urban gardens, feeding on a wide range of aphid species (Koch, 2003;Evans, 2004).…”

Can Native Geographical Range, Dispersal Ability and Development Rates Predict the Successful Establishment of Alien Ladybird (Coleoptera: Coccinellidae) Species in Europe?

et al. 2018

A list of alien ladybird (Coleoptera: Coccinellidae) species to Europe was prepared and the history and circumstances of their introductions were determined. Currently there are 12 alien ladybird species in Europe, originating from Australian, Oriental, Nearctic, Palearctic and Afrotropical regions. All of the species were intentionally released as biological control agents and most are coccidophagous species. The aphidophagous Harmonia axyridis is the only ladybird regarded as invasive in Europe. The main factors leading to successful establishment were food relationship, living in different habitats in different geographical regions and geographic origin. We found that successful invaders, in their native areas, showed adaptability to a wide range of conditions compared to non-invasive species. Larger aphidophagous alien ladybirds were found to develop as fast as native species. Characteristics that did not differ between native and alien species are thermal requirements for development, fecundity and body size. However, unlike other alien ladybirds, H. axyridis had higher potential dispersal ability.Keywords: biological invasion, Europe, fecundity, invasiveness, ladybirds, rate of spread, thermal requirements INTRODUCTIONMost species of ladybirds (Coleoptera: Coccinellidae) are carnivorous predators that feed on a variety of phytophagous arthropods including aphids, coccids and mites (Giorgi et al., 2009;Weber and Lundgren, 2009) and therefore render important services to agricultural and forest ecosystems through biological control of those pests. As such, non-native coccinellid species have been introduced around the world. Biological control using coccinellids started in the late 1800s with the successful introduction of Rodolia cardinalis Mulsant from Australia to control populations of the coccid Icerya purchasi Maskell infesting citrus orchards in California. Since then, several other ladybird species have been introduced to new regions for classical biological Soares et al. Successful Establishment of Alien Ladybirdcontrol (Roy and Migeon, 2010). The objective of the imports and releases was the establishment of self-perpetuating populations in order to exert natural control over specific pests (Michaud, 2012). Besides the benefits, this process also bears risks, including the spread and establishment of ladybirds in new geographic ranges. The monetary costs of managing alien species once established are often very high. The environmental costs (e.g., effects of an alien biological control agent on species other than the pest species) may also be high (van Lenteren et al., 2008). Thus preventing invasion in the first place is highly desirable, and in order to do this, knowledge of the pathways of invasion are needed (Hulme, 2015).Whilst there have been numerous intentional coccinellid introductions since the end of the nineteenth century (Hokkanen and Sailer, 1985), the negative impacts were only recently acknowledged (van Lenteren et al., 2003(van Lenteren et al., , 2006. The need for intensive study ...
