Sunflowers Make Bees Poop—a Lot. Here's Why That's Good
Paragraph	Text
[1]	Bumblebees and other pollinators face many threats, including pesticide exposure,
[2]	climate change, habitat loss due to agriculture and development, and pathogens
[3]	that ravage multiple species. But a recent finding may help lighten their load.
[4]	Previous studies have shown sunflower pollen can work like a medicine for
[5]	bumblebees afflicted by a parasite called Crithidia bombi, a single-celled organism
[6]	that takes up residence in the bee's gut [and harms their health]. But scientists couldn't
[7]	explain how sunflower pollen vanquished C. bombi—did it boost the bees' immune
[8]	function, or perhaps poison the parasite directly?
[9]	New research, published in the Journal of Insect Physiology, shows the answer is
[10]	deceptively simple. "Sunflower pollen makes bumblebees poo a whole lot," says lead
[11]	author Jonathan Giacomini, which flushes the parasite out.
[12]	Plant products like nectar and pollen are a treasure trove of potential insect medicines
[13]	that scientists are just beginning to understand, he adds. "There are natural things out
[14]	there that bees are interacting with that can be beneficial for them," Giacomini says.
[15]	And by making changes to the landscape, scientists hope we can help give bees a
[16]	fighting chance.
[17]	Plant power
[18]	If you happen upon a fuzzy, buzzing, flying creature in eastern North America, there's
[19]	a strong chance it's a common eastern bumblebee (Bombus impatiens). Yellow and
[20]	black striped with a rump covered in soft hairs, they're social insects that live in
[21]	colonies and love a good crevice—they build their homes in birdhouses, woodpiles,
[22]	abandoned burrows, and dense grasses.
[23]	[They] are important pollinators, both in the wild and in agriculture, where they're raised
[24]	and used to pollinate crops including tomatoes and pumpkins. Like other pollinators,
[25]	bumblebees face many threats, and C. bombi isn't even the biggest bumblebee
[26]	bugaboo. On its own, the parasite doesn't have much of an effect on a bumblebee's
[27]	health. But when food is scarce, C. bombi can shorten a bee's lifespan and even
[28]	reduce the number of young queens a colony can produce.
[29]	Lynn Adler is an evolutionary ecologist at the University of Massachusetts Amherst
[30]	who studies interactions between plants and insects. For years, she and longtime
[31]	collaborator Rebecca Irwin at North Carolina State University suspected pollinators
[32]	might be getting dosed by flowers since plants often invest chemically active
[33]	compounds into their nectar and pollen to help their genetic payload arrive at
[34]	its destination.
[35]	"Many plant defensive compounds can be medicinal at certain doses," Adler says. After
[36]	all, "most of our human medicines come from plants."
[37]	Giacomini discovered the effect of sunflower pollen as an undergraduate working in
[38]	Adler's lab in 2018. From [these] very first tests, sunflower pollen dramatically reduced
[39]	C. bombi parasite load in common eastern bumblebees, often clearing infection
[40]	completely. "We've been shocked at how consistent and effective sunflower pollen
[41]	has been," Adler says.
