Impacts of alien bees on native plant-pollinator relationships: A review with special emphasis on plant reproduction

New records reveal rapid geographic expansion of Bombus terrestris Linnaeus, 1758 (Hymenoptera: Apidae), an invasive species in Argentina

“…Montalva et al (2011) also showed that B. terrestris individuals interact preferentially with the non-native plants, which can favor their expansion through pollination service (Simberloff and Von Holle 1999;Memmot and Waser 2002). This is consistent with a growing literature suggesting that pollinator invasions can threaten local plant communities (Hingston et al 2002;Goulson 2003;Traveset and Richardson 2006;Aizen et al 2008;Dohzono and Yokoyama 2010).…”

Massively Introduced Managed Species and Their Consequences for Plant–Pollinator Interactions

“…In Boxes 1-3, we developed the potential consequences of pollinating MIMS introductions in vulnerable ecosystems as well as in agrosystems. Traveset and Richardson (2006, 2014 and Dohzono and Yokoyama (2010) reviewed the consequences of the introduction of pollinating MIMS on plant communities and highlighted three main mechanisms which may disrupt mutualistic interactions: (i) a decrease in the quantity or quality of conspecific pollen received by wild plants due to insect diet preferences or cheating behaviour (nectar robbing), (ii) a reinforcement of invasive plant pollination through invasion meltdown c and (iii) a lower reproductive success for plant species suffering of pollination deficit, especially in areas with scarce pollinators (Sanguinetti and Singer, 2014). Taken together, these mechanisms could have major collateral effects on native pollinators through modifications of plant resource availability.…”

Remote Sensing and Ecosystem Services: Current Status and Future Opportunities for the Study of Bees and Pollination-Related Services

“…These models have been particularly important for predicting the movement of invasive species, like the invasive Africanized honeybee, which may compete for resources and disrupt specialist plantpollinator mutualisms [84]. A model using 40 data layers, including MODIS (Moderate Resolution Imaging Spectroradiometer) land cover and phenology products, was used to show current Africanized honeybee distribution and predict northward movement in the future [85].…”

“…One of the biggest threats to bee conservation is the introduction of invasive species [22,84,94]. The spread of exotic honeybees may disrupt mutualistic networks and have implications for the persistence and stability of pollination services in the future [84].…”

“…The spread of exotic honeybees may disrupt mutualistic networks and have implications for the persistence and stability of pollination services in the future [84]. Studies have recorded negative impacts on native bee species but have also observed an increase in pollination services in areas invaded by feral honeybees [64,94].…”
