Urban bees use plastic to build hives Thursday, May 1, 2014 "Busy" may need to be changed to "resourceful." A recent study by scientists from the University of Guelph and York University shows that two Toronto bee species are using bits of plastic waste as construction material for their brood cells. Scott MacIvor and Andrew Moore published their findings in Ecosphere in December. By observing trap nests in Toronto, they discovered that the Megachile campanulae hives, traditionally made with plant and tree resins, had bits of polyurethane exterior house sealant incorporated into them. And the hives of Megachile rotundata (leafcutter bees), usually made with leaves, contained chewed-up pieces of plastic bags. The study shows that the use of plastics was "incidental" rather than accidental and not a result of a shortage of natural building materials. Larvae developed successfully from the trap nests. Plastic may have an advantage as it can physically impede parasites. BF Herbicide resistance a problem . . . for somebody else Behind the Lines - May 2014
