Historical Materials from University of Nebraska-Lincoln Extension

This NebGuide describes the most common species of spiders found in Nebraska, including the black widow and brown recluse, and how to control them.

General Description and Habits

Spiders can be distinguished easily from insects. All spiders have two major body regions and four pair of legs; insects have three body regions and three pair of legs.

Historical Materials from University of Nebraska-Lincoln Extension

This NebGuide provides step-by-step instructions for fumigating stored grain on the farm with aluminum phosphide.

Regardless of formulation, all fumigants are poisonous and toxic to humans and other warm-blooded animals as well as to insects and other pests. Because fumigant chemicals are highly toxic and hazardous to use, they are Restricted Use pesticides. They can only be used by ...

Historical Materials from University of Nebraska-Lincoln Extension

The life cycle and control of the chinch bug is discussed, with descriptions of possible management options.

The chinch bug is a native North American insect that can destroy cultivated grass crops, especially sorghum and corn, and occasionally small grains, such as wheat and barley. Broad-leaved plants are immune to feeding damage. Crop damage from this insect is most often found in southeast Nebraska and northeast Kansas and is associated with dry weather, especially in the spring and early summer months. Chinch bugs have few effective natural enemies. Ladybird beetles and other common insect predators found in Nebraska prefer to ...
