“…Attention has been drawn also in Europe to the similar plight of A. bipunctata and other indigenous species (e.g., C7, C. undecimpunctata and P. quatuordecimpunctata) with the establishment of H. axyridis (e.g., Lynch et al 2001;Sato and Dixon 2004;Soares and Serpa 2007;Adriaens et al 2008;Ware and Majerus 2008;Ware et al 2009;Brown et al 2011a). Burgio et al (2002) note, however, that negative impact on A. bipunctata from H. axyridis may be softened because intraguild predation does not outweigh cannibalism in interactions between these two species.…”

Invasions by ladybugs, ladybirds, and other predatory beetles

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.

“…A previous study on P. dissecta by Mishra & Omkar (2006) also reports similar results, finding reduction in egg viability in the presence of conspecific males. Soares & Serpa (2006) have observed no oviposition in Coccinella undecimpunctata L. in the presence of adult H. axyridis, but the reverse in case of conspecific adults. Females of C. sexmaculata are known to lay fewer eggs in the presence of an immobilized conspecific adult female (Agarwala et al, 2003), whereas C. septempunctata does not oviposit in the presence of conspecific adult females (Hemptinne et al, 1993).…”

Abstract.Reduced oviposition by ladybirds in the presence of tracks of fourth instar larvae owing to the presence of oviposition deterring pheromones is well established across many genera. However, deterrence, if any, by other life stages has not been well investigated, in particular the effect of conspecific presence. The present study investigates the effects of conspecific presence and semiochemicals of conspecific life stages (eggs, fourth instar larvae, pupae, adult males and females) on oviposition by five ladybird (Coleoptera: Coccinellidae) species, viz. Coccinella septempunctata, Coccinella transversalis, Cheilomenes sexmaculata, Propylea dissecta and Anegleis cardoni. Results reveal that the presence of life stages inhibits oviposition and the inhibition is densitydependent, although the degree of inhibition is species-specific. Surface semiochemicals of eggs and larval and adult tracks also show density-dependent inhibitory effects. Moreover, the semiochemicals in tracks (oviposition deterring pheromones) and egg surface semiochemicals are not similar, indicating semiochemical parsimony. Of all species tested, C. transversalis and C. septempunctata were the most and the least responsive to both conspecific presence and semiochemicals, respectively.

“…Moreover, laboratory experiments demonstrated that the presence of H. axyridis adults significantly affected the reproductive numerical response of C. undecimpunctata even though the resource was not in short supply. The results suggested that interference competition with heterospecifics may adversely affect the reproductive capacity of C. undecimpunctata (Soares and Serpa 2007).…”

“…It has been demonstrated that H. axyridis is more aggressive than other invasive and indigenous species in many laboratory experiments (Hironori and Katsuhiro 1997;Cottrell and Yeargen 1998;Yasuda and Ohnuma 1999;Yasuda et al 2001;Cottrell 2004;Soares and Serpa 2007;Pell et al 2007;Ware and Majerus 2007). The incidence of IGP, in laboratory studies, was 65% for the interactions between all stages of H. axyridis (intraguild predator) and the indigenous C. maculata (intraguild prey), and 75% for H. axyridis and the invasive P. quatuordecimpunctata (Labrie et al unpublished data).…”

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

View full text Add to dashboard Cite

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
