The Colorado potato beetle wreaks havoc on potato plantings and is also notorious for becoming insecticide-resistant.
According to the portal potatonewstoday.com, in the journal Crop Science published a study by scientists from Michigan State University, dedicated to the description of genetic tools to create new varieties of potatoes with improved natural resistance to the pest.
The researchers have also created recombinant inbred lines that will aid in the development of new varieties of potatoes.
Some of the wild relatives of modern cultivated potatoes have natural defenses against the beetle. "Savages" produce their own compounds capable of killing the larvae and the beetle itself.
For humans, these compounds are dangerous in large quantities, so it is necessary to create varieties that will produce these compounds only in inedible potato leaves. The beetles will eat the leaves and die.
This summer, scientists have expanded the field trials of the resulting resistant plants.
