title: First record of the invasive bumble bee Bombus terrestris (Hymenoptera: Apidae) on Navarino Island, southern Chile (55 ° S)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Cárcamo, Javier Rendoll, Contador, Tamara, Saavedra, Lorena, Montalva, José (2017): First record of the invasive bumble bee Bombus terrestris (Hymenoptera: Apidae) on Navarino Island, southern Chile (55 ° S). Journal of Melittology 2017 (71): 1-5, DOI: 10.17161/jom.v0i71.6520, URL: http://dx.doi.org/10.17161/jom.v0i71.6520Abstract. As the volume of global trade expands, so does the risk of alien species reaching new regions. Bombus (Bombus) terrestris (Linnaeus) (Hymenoptera: Apidae) is a bumble bee traded internationally for crop pollination and is now considered an invasive species in New Zealand, Japan, and throughout South America. We newly document its presence on Navarino Island, Cape Horn, Biosphere Reserve, Chile (55°S), the southernmost locality reached by this species to date.The genus Bombus Latreille comprises around 250 species distributed almost worldwide (Michener, 2007; Williams et al., 2008). For Chile, two native species have been described, Bombus (Cullumanobombus) funebris Smith, 1854 and B. (Thoracobombus) dahlbomii Guérin-Méneville, 1835, in addition to the two recent introductions of B. (Megabombus) ruderatus (Fabricius, 1775) and B. (Bombus) terrestris (Linnaeus, 1758) (Montalva et al., 2011). The last of these species, B. terrestris, could become a serious threat to biodiversity globally (Sutherland et al., 2017; Geslin et al., 2017). This species was deliberately introduced in Chile in 1997 as a pollinator of tomato (Solanum lycopersicum L.) and avocado plants (Persea americana Mill.) (Montalva et al., 2008). Bombus terrestris was introduced to the Magellanes region in the summer seasons of 2011–2012, 2012–2013, and 2013–2014 through an INIA (Instituto de Investigaciones Agropecuarias) project to assess its capability as a pollinator of red currant, Ribes rubrum L. (Pérez, 2013; Estay & McLeod, 2014). The first European bumble bee colonies were used in greenhouses at INIA Kampenaike, Punta Arenas (52°S) (Estay & McLeod, 2014). Since then, more colonies have been privately introduced for pollinating tomato plants (Díaz Tavie, pers. comm).1 Laboratorio de Ecología Dulceacuícola Wankara, Universidad de Magallanes, Teniente Muñoz 166, Puerto Williams, Chile (javier.rendoll@gmail.com, contador.tamara@gmail.com).2 Programa de Conservación Biocultural, Universidad de Magallanes, Teniente Muñoz 166, Puerto Williams, Chile.3 Instituto de Ecología y Biodiversidad, Universidad de Chile, Las Palmeras 3425 Ñuñoa, Santiago, Chile (l.saavedra.aracena@gmail.com).4 Salvemos Nuestro Abejorro, 712 Terril Road, Menomonie, Wisconsin 54751, USA (montalva. jose@yahoo.es).doi: http://dx.doi.org/ 10.17161/jom.v0i71.6520In the latest reports of this species’ distribution from the citizen science program, ‘ Salvemos Nuestro Abejorro’ (Save our Bumble Bee), B. terrestris is recorded from the Coquimbo region (30°S) to the Magellanes region (51°S), including Chiloé Island (Montalva et al., 2015), spanning 21 degrees of latitude. Recently, Simonetti et al. (2016) documented the presence of naturalized B. terrestris since 2013 on Riesco Island (52°51´S, 71°33´W).The dispersal rate of B. terrestris is estimated to be around 200 km per year (Schmid-Hempel et al., 2014). It arrived in Argentina in 2006 (Lanín National Park, Neuquén Province), a country that had banned B. terrestris importation, from Chile (Torreta et al., 2006), probably through low elevation passes across the Andes, eventually reaching Río Gallegos (51°37´S, 69°12´W) in 2014 (Geslin & Morales, 2015).
