Corn Flea Beetle
A very small, shiny black to bronze flea beetle with a compact, oval body. It vectors Stewart's wilt bacterium, making it both a direct and indirect pest of sweet corn.
Did You Know?
The severity of Stewart's wilt in a given year can be predicted by winter temperatures, since cold winters reduce overwintering beetle populations.
Corn Planthopper
A cosmopolitan planthopper pest of maize with a yellowish-brown body. It transmits maize mosaic virus and maize stripe virus, causing significant crop losses in tropical regions.
Did You Know?
Its species name 'maidis' comes from Zea mays (maize), and it is one of the most widely distributed planthoppers, found on every continent where corn is grown.
