Mp92-63 Adult Corn Rootworm Management, Lance J. Meinke

University of Nebraska-Lincoln Extension: Historical Materials

The western corn rootworm (WCR), and the northern corn rootworm (NCR) are among the most economically important insect pests of field corn in the Unitd States. Crop losses and control expenses attributed to corn rootworms annually cost producers millions of dollars. Corn rootworm larvae can cause substantial injury to corn plants by feeding on corn roots.

This Extension circular covers these two corn rootworms, their population dynamics, management considerations, and research/emerging technologies.

University of Nebraska-Lincoln Extension: Historical Materials

Mixing, safety, restrictions, and precautions for insecticides used to control external swine parasites.

Hog Lice and Mange Mites

External parasites of swine include the hog louse and two species of mange mites (the common itch mite and the less common hog follicle mite). Excessive scratching and rubbing by pigs nearly always indicate an infestation of hog lice or mange mites.

Hog lice and mange mites infest a high percentage of swine slaughtered at Midwest slaughter plants.
