Corn rootworm control 1984
"The three species of corn rootworms attacking corn in Missouri are commonly known as northern, southern and western corn rootworms. The northern and southern species are state-wide in their distribution. The western species is known to occur over the northern two-thirds of the state Gasper to Perry Counties and northward). Western corn rootworm larval and adult numbers were on on the increase in 1983 and comprised over 90 percent of the total rootworm population in the research plots in northwest Missouri. The potential for economic damage from northern and western species is also confined to the northwestern counties, extending from Buchanan County northeastward to Harrison County."--First page.
