But surely widespread pesticide usage wouldn’t have similar subtle effects on the growth and development of humans.Via the Guardian:
Bumblebees could be shrinking because of exposure to a widely-used pesticide, a study suggests.
Scientists in the UK conducted laboratory tests which showed how a pyrethroid pesticide stunted the growth of worker bumblebee larvae, causing them to hatch out reduced in size.
Pyrethroid pesticides are commonly used on flowering crops to prevent insect damage. The study, the first to examine the pesticides’ impact across the entire lifecycle of bumblebees, tracked the growth of bee colonies over a four month period.
Currently a Europe-wide moratorium on the use of three neonicotinoid pesticides is in force because of their alleged harmful effect on bees. As a result, the use of other types of pesticide, including pyrethroids, is likely to increase, say the researchers.
