A: Motta et al. (2018) is a complicated study, that tests a hypothesis that inhibition of EPSPS in the gut microbiome can result in increased susceptibility to opportunistic pathogens, but some of the experimental conditions make interpretation equivocal. Results from laboratory studies that assess toxicity to individual honey bees are not automatically indicative of effects to honey bee colonies. The reason for this is that honeybees often respond differently when they are exposed as part of a colony. To address this difference, EPA’s scheme for testing effects to honey bee’s progresses from hig [...]
