Q&A with entomologist: Fewer bees and other pollinating insects lead to shrinking crops

Many plants, from crops to carnations, cannot bear fruit or reproduce without bees, beetles, butterflies and other insects to pollinate them. But the population of insect pollinators is dropping in the U.S., due in part to pesticides, climate change, invasive plants and diminished habitats. Rachel Mallinger, assistant professor of entomology at the University of Florida, explains why these insects are in decline and how homeowners can create yards and gardens that are good for pollinators.
