Chlidoplitis and Megahoplitis are closely related Palaearctic subgenera of the osmiine bee genus Hoplitis (Megachilidae) containing nine and two species, respectively. Analysis of female pollen loads and field observations suggest that all species are pollen specialists. Whereas the H. (Chlidoplitis) species are probably all narrowly oligolectic and exclusively collect pollen on Allium (Alliace...

The relative importance of bottom-up or top-down forces has been mainly studied for herbivores but rarely for pollinators. Habitat fragmentation might change driving forces of population dynamics by reducing the area of resource-providing habitats, disrupting habitat connectivity, and affecting natural enemies more than their host species. We studied spatial and temporal population dynamics of ...

More than one-third of the world’s crops require pollination to set seeds and fruits Dias et al. [1]. It is likely that wild bee community is sufficient to provide services for multiple crops, including some that are not serviced by honeybees Kremen et al. [2]. Under several situations non-Apis bees are better pollinators than Apis species because of efficient tripping, fast foraging rate, long...
