    Description: Comments by de Jong et al., Solter et al., and Sloggett question the ecological relevance of the abundant microsporidia found in the invasive ladybird Harmonia axyridis. We contend that there is abundant evidence that native ladybirds feed on H. axyridis eggs and that interspecific microsporidial transfer is a common phenomenon, supporting the proposed role of these parasites as biological weapons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vilcinskas, Andreas -- Stoecker, Kilian -- Schmidtberg, Henrike -- Rohrich, Christian R -- Vogel, Heiko -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1342. doi: 10.1126/science.1242484.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Phytopathology and Applied Zoology, Heinrich-Buff-Ring 26-32, Justus-Liebig-University of Giessen, D-35392 Giessen, Germany. andreas.vilcinskas@agrar.uni-giessen.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24052293" target="_blank"〉PubMed〈/a〉

    Description: Invasive species that proliferate after colonizing new habitats have a negative environmental and economic impact. The reason why some species become successful invaders, whereas others, even closely related species, remain noninvasive is often unclear. The harlequin ladybird Harmonia axyridis, introduced for biological pest control, has become an invader that is outcompeting indigenous ladybird species in many countries. Here, we show that Harmonia carries abundant spores of obligate parasitic microsporidia closely related to Nosema thompsoni. These microsporidia, while not harming the carrier Harmonia, are lethal pathogens for the native ladybird Coccinella septempunctata. We propose that intraguild predation, representing a major selective force among competing ladybird species, causes the infection and ultimate death of native ladybirds when they feed on microsporidia-contaminated Harmonia eggs or larvae.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vilcinskas, Andreas -- Stoecker, Kilian -- Schmidtberg, Henrike -- Rohrich, Christian R -- Vogel, Heiko -- New York, N.Y. -- Science. 2013 May 17;340(6134):862-3. doi: 10.1126/science.1234032.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Phytopathology and Applied Zoology, Heinrich-Buff-Ring 26-32, Justus-Liebig-University of Giessen, D-35392 Giessen, Germany. andreas.vilcinskas@agrar.uni-giessen.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23687046" target="_blank"〉PubMed〈/a〉
