Adult northern corn rootworm are in (6 mm) long with uniformly greenish to yellowish color and no markings on the wing covers. Adult southern corn rootworm are between in ( mm) long, with a yellow-green body, black head and antennae, and 12 black spots on their wing covers. In Canada, northern corn rootworm is found in southern Ontario and Quebec. Northern corn rootworm and western corn rootworm, Diabrotica virgifera LeConte, can both be found in the same fields, but western corn rootworm has displaced northern corn rootworm, or at least reduced its abundance, in some areas. Displacement has been attributed to.
Corn rootworms (including western, northern and southern corn rootworms) are a major pest to corn plants and can cause significant crop damage. The good news is that beneficial nematodes are a great, all natural and completely safe way to kill these insect pests. The larvae and adults of southern corn rootworm feed on many plant species. Damage: Larvae of all species feed on corn roots. Feeding may result in plant lodging, “goosenecking”, and yield loss. Southern corn rootworm larvae also may decrease corn plant stand by feeding on developing seedlings. Adults feed on corn silks, leaves, and pollen.

The three species of rootworm found in Iowa include the northern corn rootworm (NCR), southern corn rootworm (SCR), and western corn rootworm (WCR). Adults of all three species can be found until the first frost. Knowing how to distinguish the three species is important for making management decisions for future growing seasons.
Southern Corn Rootworm This insect is often called the corn budworm (Diabrotica undecimpunctata howardi), which in South Carolina more accurately describes its habits than the name rootworm. It is not usually found in the roots and as a rule does not feed on them, as is the case with rootworms.
The adult southern corn rootworm is 5 to 9mm long. The beetle is a bright yellow-green and has a black head, antennae, and legs.
They typically have 11 black spots on their back. The egg is a light yellow, oval in shape and a short mm in length. Southern Corn Rootworm The southern corn rootworm damages corn by feeding on the root system.
The adult southern corn rootworm female lays eggs around the base of seedling plants in early spring and the larvae move Table 2.

Labels related to the pest - Beetle, Southern Corn Rootworm. The spotted cucumber beetle or southern corn rootworm (Diabrotica undecimpunctata) is a species of cucumber beetle that is native to North America.
The species can be a major agricultural pest insect in North America. Spotted cucumber beetles cause damage to. Corn. Studies on corn pests suggest that closely related insect species can have different responses to conservation tillage when compared to conventional tillage.
Under reduced tillage, western corn rootworm populations increased , northern corn rootworm populations were unaffected  and southern corn rootworm populations decreased .
Range. Corn rootworms are one of the most economically significant consumers of maize in the United States. The western corn rootworm, D. virgifera virgifera, and the northern corn rootworm, D. barberi, are the most significant rootworm species in Iowa, a major corn-growing area.A third species, the southern corn rootworm, D.
undecimpunctata howardi, causes much economic damage in other. Southern Corn Rootworm, Diabrotica undecimpunctata howardi Barber Southern corn rootworm (SCR) adults are approximately 3/8 inch long and yellow to green with eleven black spots on the forewings (elytra).
Eggs, larvae, and pupae of the SCR are similar in appearance to the same stages of NCR and WCR. This species overwinters as an adult, instead. The male rootworm from this type is usually smaller and darker. The Northern Corn Rootworm, on the other hand, has a green to yellow body and the female is usually the one that is larger.
It has an average length of ¼ inch. Lastly, the Southern Corn Rootworm has a green body that is easy to distinguish because of the black spots on its back.
