This study tests if nectar yeast additions affect floral scent and bumble bee foraging behavior, finding no significant impact on either.

This study evaluates the effectiveness of Puccinia suaveolens as a biocontrol agent for Canada thistle, both alone and in combination with other methods, showing mixed results.

This study examines how temperature affects the microbiota of solitary bee provisions and larval health, finding that heat stress alters microbial composition but does not significantly impact survivorship.

The paper assesses how microbial biological control agents (mBCAs) affect Erwinia amylovora resistance in pear nectar through priority effects, finding that nectar pH and sucrose changes are key predictors.

This study reports on an 8-year monitoring effort of a biological control program using the rust fungus Puccinia punctiformis to reduce Canada thistle stem densities in Colorado, finding declines linked to environmental factors and inoculum deployment.

This study investigates how microbial metabolites in nectar influence bumble bee attraction and feeding behavior through volatile and non-volatile cues.
