Summary
In the present work, we update floral associations and geographical distribution for four species of Bombus present in Chile, two native (B. dahlbomii and B. funebris) and two introduced species (B. terrestris and B. ruderatus). We also examine possible associations among native or introduced bees with native or introduced plant species. We found a significant non-random plant association among non-native bumble bee species and non-native plant species. Because of the distributional overlap between B. dahlbomii with the two non-native bee species, it is likely that B. dahlbomii interacts with these non-native bees.
Resumen
En este trabajo actualizamos las asociaciones florales y la distribución geográfica de las cuatro especies de Bombus presentes en Chile, dos especies nativas (B. dahlbomiiy B. funebris) y dos especies introducidas (B. terrestres y B. ruderatus). Examinamos las posibles asociaciones entre abejas nativas o introducidas con las especies nativas o introducidas de plantas. Encontramos una asociación significativa no aleatoria entre especies de abejorros introducidos con especies de plantas introducidas. El solapamiento de la distribución de B. dahlbomii con los abejorros introducidos es probable que se produzca por la relación entre estas especies.
