Miss Carson and other scientists were very concerned about the harmful effects of DDT and other insect-killing chemicals called pesticides.

She says the effect of disease is made worse by the buildup of insect-killing pesticides in bee colonies.

The study found that many farmers have better harvests, better weed control and fewer losses from insect damage compared to traditional crops.

The team also tested the insect material on methicillin-resistant staphylococcus aureus, also known as the disease MRSA.

are very similar genetically. "And that's a real problem when you're trying to overcome new insect or disease threats or pressures, or trying to breed a plant that's more water efficient, or even finding genetic variation for water production."
