Asymmetric larval interactions between introduced and indigenous ladybirds in North America

Abstract: Understanding the mechanisms that result in the success of introduced species will contribute to predicting future invasions and managing invaded systems. We examined interactions between larvae of two predatory ladybird species recently introduced to North America, Coccinella septempunctata (CS) and Harmonia axyridis (HA), and two indigenous ladybirds, Coccinella transversoguttata (CT) and Hippodamia convergens (HC). By pairing young and old larvae in the laboratory at low and high levels of aphid availabilit… Show more

“…Studies to date have failed to show that H. 365 axyridis negatively affects native North American ladybirds through exploitative competition among 366 larvae (Hoogendoorn, Heimpel 2004;Yasuda et al 2004), however, field and microcosm studies 367 reveal reduced fitness in the predatory bug Anthocoris nemoralis (F.) (Hemiptera: Anthocoridae) due 368 to competition with H. axyridis . Evans (2004) proposed that following the 369 introduction of alien competitors (specifically C. septempunctata), native species abandoned 370 croplands due to increased competition for shared prey.…”

“…Yasuda and Ohnuma 1999;Yasuda et al 2004;Pell et al 2008;Ware and Majerus 2008;Raak-van den Berg et al 2012), little data is available on H. axyridis as an intraguild prey. Indeed, in experiments testing the outcomes of intraguild interactions involving H. axyridis, it usually appears superior to other aphidophagous predators (Yasuda and Ohnuma 1999;Yasuda et al 2004;Ware and Majerus 2008;Raak-van den Berg et al 2012; Katsanis et al 2013). A few exceptions include larvae of the ladybird Anatis ocellata (L.) Katsanis et al 2013) and of the lacewings Chrysoperla carnea (Stephens) (Nedvȇd et al 2010(Nedvȇd et al , 2013 and C. rufilabris (Burmeister) (Michaud and Grant 2003).…”

“…First, as with many other exotics, H. axyridis may threaten native organisms. For example, densities of native predators seem to have decreased as the abundance of H. axyridis increased (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).…”
