Ec99-1563 Corn Rootworm Management, Robert J. Wright, Lance J. Meinke, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

Corn rootworms (Diabrotica spp.) are one of the most economically important corn insects in Nebraska. The western corn rootworm, D. virgifera virgifera LeConte, and the northern corn rootworm, D. barberi Smith and Lawrence, are the most economically important rootworm species in Nebraska. A third species, the southern corn rootworm, D. undecimpunctata howardi Barber, causes little economic damage to corn and has not been shown to overwinter in Nebraska. This publication will focus on the biology and management of the western and northern corn rootworms.

G99-1389 Cultural Practices To Improve Weed Control In Winter Wheat, Gail A. Wicks, Alex Martin, Drew J. Lyon

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains the influence of cultural practices on weeds in winter wheat. Precipitation and temperature greatly influence crop and weed growth in the semiarid areas of the central Great Plains. Precipitation in Nebraska varies from 14 to 24 inches where fallow is practiced. The purpose of fallow is to control weeds and, when not cropping a field, to store water and stabilize winter wheat fields. With good prewheat-fallow techniques, sufficient soil moisture is usually available to establish winter wheat. Peak rainfall occurs in May and June during the pollination and grain-filling period of winter wheat. The latter part of …

G99-1377 Tree Squirrels And Their Control, Dallas R. Virchow, Scott E. Hygnstrom, John M. Hobbs

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes tree squirrel biology and behavior and characterizes the types of damage they cause. It suggests control methods and equipment and describes legal restrictions.

Tree squirrels are known for their bushy tails and their ability to climb high into trees. The eastern fox squirrel (Sciurus niger) is the most common tree squirrel in Nebraska. It is common throughout the state. The eastern gray squirrel (Sciurus carolinensis) occurs only in the extreme southeastern portion of Nebraska. The southern flying squirrel (Glaucomys volans) occurs uncommonly and only in southeastern Nebraska in the forested Missouri …
