NC State: Lack Of Plant Diversity Fuels Cankerworm Damage

North Carolina State University researchers are looking into stopping an invasive species of caterpillar that can damage and kill urban trees and shrubs.   

Cankerworms are born from the eggs of wingless moths.  The moths climb the trunks of trees to nest in the winter.

N.C. State professor and entomologist Steve Frank says these young larvae do most of the damage to trees and bushes that dot the city landscape.

"And then in early Spring just as the leaves are opening on the trees, the cankerworm eggs hatch and the caterpillars start eating the leaves," says Frank.

NC State Study: Genetic Diversity Key To Honey Bee Survival

Honey bee populations have been struggling in recent years. New research out of NC State underlines the importance of genetic diversity as key to the honey bees' survival. The study took samples from 80 commercial colonies used to pollinate about a third of the food we eat. It found queens that mated at least seven times were nearly three times more likely to survive the season.

Ready Or Not, Here Come The Cicadas!

North Carolinians in the western Triangle and Triad soon will be visited en masse by the ear-splitting song of the 17-year cicadas. Over the next ten days or so, cicadas from  a group classified as Brood II will begin emerging from the ground and begin a month-long mating frenzy. The females will lay their eggs by sawing little slits into twigs on trees and depositing their eggs into those slits. When the eggs hatch, the nymphs drop to the ground and tunnel into the soil to feed on tree roots, where they'll stay for another 17 years until they become adults.
