MSc (Entomology), PhD (Entomology), University of California, Davis
Students Advised:
Dr Guzman has advised or co-advised the theses of more than 35 DVM, MSc and PhD students.
Honey bee breeding, genetics and behaviour. Honey bee pathology.
Research in Dr Guzman's lab is focused on three main areas: genetics, behaviour and parasitic mites of honey bees. These studies have contributed to the understanding of foraging behaviour, defensive behaviour and the mechanisms that provide honey bees resistance against parasitic mites, which is the most serious problem facing beekeepers worldwide. Currently, postdoctoral fellows, students and technicians in Dr Guzman's lab are investigating the effect of parasites and pesticides on the behaviour and immune responses of honey bees.
