Mountain Pine Beetle In Ponderosa Pine: Effects Of Phloem Thickness And Egg Gallery Density, Gene D. Amman, Judith E. Pasek

Judith E Pasek

Effects of phloem thickness in ponderosa pine (Pinus ponderosa) on mountain pine beetle (Dendroctonus ponderosae) were determined in a laboratory study. Brood production, beetle size, sex ratio, and rate of emergence were significantly related to phloem thickness, egg gallery density, and attack density.

G86-806 Chinch Bug Management (Revised January 1993), Barbara P. Spike, Robert J. Wright, Stephen D. Danielson

University of Nebraska-Lincoln Extension: Historical Materials

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 …

G86-792 Spiders, David L. Keith, Stephen D. Danielson, Timothy P. Miller

University of Nebraska-Lincoln Extension: Historical Materials

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. Spiders vary widely in color, shape, size, and habits. All produce venom that is poisonous to their normal prey. Few spiders are considered dangerous to humans, however. These animals are predacious by nature and use their venom, which is injected through hollow fangs …

G86-790 Fumigating Farm-Stored Grain With Aluminum Phosphide (Revised May 1998), Clyde Ogg, David L. Keith

University of Nebraska-Lincoln Extension: Historical Materials

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

Fumigants act on all insect life stages. They control pests by diffusing through the air spaces between grain kernels as well as into the kernel itself. Fumigants are able to penetrate into places that are inaccessible to insecticide sprays or dusts.

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 …
