(Maine Public) A bill making its way through the Maine Legislature seeks to restrict and limit the use of four specific pesticides: clothianidin, dinotefuran, imidacloprid and thiamethoxam. Under the bill, the named pesticides would no longer be available for home and landscape use, and would require certification for use.
(Oregon State University) The mid-Cretaceous fossil from Myanmar provides the first record of a primitive bee with pollen and also the first record of the beetle parasites, which continue to show up on modern bees today.
(National Geographic) Ancient nests confirm that bees were alive and well in Patagonia 100 million years ago, marking the oldest fossil evidence for modern bees. The nests consist of tunnels studded with grape-shaped alcoves and look almost exactly like the nests of of modern halictid bees.
(Duluth News Tribune) Early results of Bee Innovative’s research in North Dakota sunflower fields show the potential for increased quality of seeds and, as a result, increased income to farmers. The company’s BeeDar tracks the movement of bees as they pollinate a field; if part of the field isn’t being pollinated, bees can be moved in to service that portion. Bee Innovative is looking to establish a U.S. company later in 2020 and North Dakota is a front-runner.
(Phys.org/University of Freiburg) Over many years, researchers from the University of Freiburg have compiled data on the global pollination of major crop plants, above all, fruit and vegetables. Together with scientists from the Federal University of Ceará in Fortaleza, Brazil, they have analyzed the data and developed a “Pollination Guide” for Brazil. The guide is intended to give Brazilian farmers information on the importance of bees and other pollinating insects, so that they treat the habitats of wild pollinators with care.
(NPR) Winter is downtime for honey bees. They settle in their hives and rest. But this winter has been unusually warm in some places, and that’s causing some major headaches for beekeepers.
(Entomology Today) Varroa mites are responsible for heavy economic losses, caused by their infestation of beehives in almost every corner of the globe. But how did this problem start, what does this pest do, and what does the future look like for honey bees? These questions are answered in detail in a new article on the biology and management of Varroa mites.
(University of Helsinki) Humanity is pushing many ecosystems beyond recovery. As a consequence, unquantified and unquantifiable insect extinctions are happening every day. Two scientific papers by 30 experts from around the world discuss both the perils and ways to avoid further extinctions, intending to contribute towards a necessary change of attitude for humanity’s own sake.
