The Great Lakes region has been invaded by another non-native species. But this one may be more beneficial than it is a nuisance. The Great Lakes Radio Consortium’s Tracy Samilton reports on the Asian ladybird beetle.


They’re everywhere, it seems: landing on us and pacing up and down the windows of our homes. The ladybug look-alikes were first introduced in the South. And they’ve since moved north. Tom Ellis is an entomologist at Michigan State University.

The bugs main prey is aphids and last year’s healthy aphid population means a lot of beetles too. The beetles are probably here to stay and there may be even more of them next year. For the Great Lakes Radio Consortium, I’m Tracy Samilton.

Mutant Ladybugs Control Pests

It’s nothing new to get predators to get rid of pests. The colorfuland cute ladybug, for example, loves to devour aphids, mites andmealybugs and is used by many people instead of pesticides. But workingwith these flying predators presents some problems. Now, one researchermay have a solution. The Great Lakes Radio Consortium’s Wendy Nelsonreports:
