FRIDAY, April 5, 2019 (HealthDay Information) — You now have an excuse to skip chopping the grass each weekend — it is useful for the bees.
And mowing your garden much less typically to offer native bees a greater habitat will not result in a rise in disease-carrying ticks, specialists say.
When analysis ecologist Susannah Lerman started urging buddies and colleagues to go away lawns a bit longer to assist the bees, the “very first thing folks stated was that letting the grass get longer would invite ticks,” she recalled.
“It was clear that earlier than we may make the case for selling lawns as bee habitat, we needed to perceive the tick threat,” Lerman added.
She and Vince D’Amico, a fellow USDA Forest Service analysis entomologist, studied whether or not much less frequent mowing of 16 residential lawns in Springfield, Mass., over two summers may benefit native bees with out growing the chance of ticks.
The researchers discovered 111 bee species on the lawns — about one-quarter of all recognized bee species in Massachusetts. In addition they dragged a fabric throughout the lawns searching for ticks. In 144 tick drags, accomplished with grass at numerous heights and mowing frequencies, they did not discover a single blacklegged tick. Additionally known as deer ticks, the bugs can carry Lyme illness, a bacterial an infection that may make folks significantly in poor health.
The research was printed on-line April three within the journal PLoS One.
The researchers stated the research has some “apparent limitations” — they regarded for just one species of tick and solely studied 16 lawns in a single metropolis.
“Nonetheless,” Lerman stated, “our research has two vital take-aways: you don’t essentially invite ticks in case you mow the garden each different week as a substitute of each week, and customary assumptions about nature are at all times value investigating; scientists could also be shocked by what we discover.”
Whereas there is no doubt that blacklegged ticks lurk in folks’s yards, a garden might be too dry for them, in accordance with D’Amico.
“This species wants close to 100% humidity for a minimum of a part of the day,” he defined in a U.S. Division of Agriculture Forest Service information launch. “The place we’ve got leaf litter, the ticks do very nicely.”
In the USA, about 40 million acres of garden managed by owners, companies, authorities companies and cemeteries have the potential to turn into habitat for threatened native bee species.
