• Lessons from lady beetles: accuracy of monitoring data from US and UK citizen-science programs (2012, unknown): “2009) but also because of concerns that historically widespread and common lady beetle species have declined dramatically in both the US and UK (Harmon et al. 2007; Roy et al. 2012).”
• Decline in native ladybirds in response to the arrival of Harmonia axyridis: early evidence from England (2011, background): “…declined as a consequence of the arrival of H. axyridis (Majerus, 2008) and strong evidence that A. bipunctata seriously declined in response to the arrival of non-native species C. septempunctata, and particularly H. axyridis, in North America (Colunga-Garcia & Gage, 1998; Harmon et al., 2007).”
• Benefits and risks of exotic biological control agents (2011, unknown): “…ladybird, H. axyridis, has now been studied extensively and numerical and/or proportional declines of certain native coccinellids, like A. bipunctata, have been observed in its invasive range (Harmon et al. 2007; Adriaens et al. 2008; Brown et al. 2011a; De Clercq and Bale 2011; Evans et al. 2011).”
• Shifting paradigms in the history of classical biological control (2018, background): “…of native coccinellids by introduced species such as Harmonia axyridis (Pallas) and Coccinella septempunctata Linnaeus within agricultural fields in the United States is not included because it is not clear whether these non-target effects extend into natural areas (Evans 2004; Harmon et al. 2007).”
• Coccinellids in Biological Control (2012, unknown): “Rather, native species may simply equilibrate to lower population densities in the cultivated or disturbed habitats dominated by invasive species, or retreat to more feral, ancestral habitats (Evans 2004 , Acorn 2007 , Harmon et al. 2007 ).”
• Worldwide decline of the entomofauna: A review of its drivers (2019, background): “tion sizes did not change much until 1986, when a major decline in native species began to be noticed and affected 68% of species over the following 20 years (Harmon et al., 2007).”
• Eating their way to the top? Mechanisms underlying the success of invasive insect generalist predators (2010, background): “Similarly, other native lady beetle species that have been displaced from some habitats persist elsewhere in the landscape (Harmon et al. 2007).”
• European buckthorn and Asian soybean aphid as components of an extensive invasional meltdown in North America (2010, background): “It is a strong intraguild competitor and has been implicated in the decline of several species of native lady beetles (Koch 2003; Harmon et al. 2007).”
• Assessing the trophic ecology of the Coccinellidae: Their roles as predators and as prey (2009, background): “reductions in coccinellid diversity are coupled with the range expansion of invasive species (Harmon et al., 2007).”
• The harlequin ladybird, Harmonia axyridis: global perspectives on invasion history and ecology (2016, background): “Indeed declines of native ladybirds have been reported across the USA (Alyokhin and Sewell 2004; Bahlai et al. 2014; Colunga-Garcia and Gage 1998; Evans 2004; Harmon et al. 2007; Hesler and Kieckhefer 2008; Losey et al. 2014; Majerus et al. 2006; Wheeler Jr and Hoebeke 1995) and Europe (Roy et al. 2”
• Landscape composition influences patterns of native and exotic lady beetle abundance (2009, background): “Several authors concluded that this decline is tied to the establishment of exotic coccinellids (Putnam, 1955; Wheeler & Hoebeke, 1995; Elliott et al., 1996; Michaud, 2002; Evans, 2004; Snyder et al., 2004; Snyder & Evans, 2006; Harmon et al., 2007).”
• Bad side of a good beetle: the North American experience with Harmonia axyridis (2008, background): “Over the last two decades, this species has spread throughout much of the continental USA and southern Canada.”
• The role of exotic ladybeetles in the decline of native ladybeetle populations: evidence from long-term monitoring (2015, background): “In North America, coccinellid communities are increasingly dominated by exotic species, leading to concerns for native species which have dramatically declined in abundance in recent decades (Harmon et al. 2007).”
• Insect Declines in the Anthropocene. (2020, background): “A special case, where there are ample data, is the competitive displacement of native lady beetles by exotic species introduced for biocontrol purposes (5, 16, 53, 70).”
• Invasive alien predator causes rapid declines of native European ladybirds (2012, background): “The correlation between the presence of the invasive alien zebra mussel, Dreissena polymorpha (Pallas), and decline of unionid mussels in North America (Ricciardi et al., 1998; Ricciardi & Rasmussen, 1999) is unquestionable (Ricciardi, 2004), but the arrival of this particular IAS appears to be only”
