A study looking at floral density and pollinators finds that some types of pollinating insects prefer dense flower patches more than others, but that preference can also vary by flower species, too. The complicated findings offer clues to how multiple pollinator species co-exist and compete for floral resources.
In many agricultural settings, insect pest traps can also attract bees. In a new report, a group of researchers examine ways to reduce bee bycatch in pest traps while also exploring how bee bycatch can aid in assessing bee biodiversity, population levels, range shifts, and more.
An experiment with four-sided nest boxes for alfalfa leafcutting bees showed small variations in environmental conditions from one nest-cavity location to another make a big difference in the bees' nesting preferences and number of offspring.
A new collection of reports in Environmental Entomology highlights the need for pesticide risk assessments that account for the differing qualities and behaviors between honey bees and bumble bees, solitary bees, and stingless bees.
With high-speed, high-definition cameras, researchers at the University of Arizona got an unprecedented look at the mating habits of the solitary bee species Diadasia rinconis and gained new insights into their courtship behaviors and the selective pressures those behaviors produce.
