more insects

………………………………….

A rise in the Earth’s temperature could lead to an increase in the number of insects worldwide, with potentially dire consequences for humans, a new study suggests.

New research shows that insect species living in warmer areas are more likely to undergo rapid population growth because they have higher metabolic rates and reproduce more frequently. The consequences could be more serious than just a few extra bug bites each summer.

“If they’re crop species, we could count on needing to use more pesticides and it could be very costly,” said Melanie Frazier, a doctoral student at the University of Washington and lead author of the study.
