G93-1136 Potato Leafhopper Management In Alfalfa, Stephen D. Danielson, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to detect and manage potato leafhoppers to minimize alfalfa damage.

The potato leafhopper is capable of causing serious damage to alfalfa in Nebraska. This insect overwinters in the gulf states and migrates northward in the spring, usually in April or early May. During the summer months, several generations develop while feeding primarily on legumes such as alfalfa and clover. Although an occasional host, soybeans rarely suffer economic damage, particularly with the pubescent (i.e. hairy) soybean varieties that are commonly grown today. Infested potatoes also can sustain economic damage from this insect. Generally, the potato leafhopper is …

G93-1167 Spider Mite Management In Corn And Soybeans, Robert J. Wright, Ronald C. Seymour, Leon G. Higley, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the two common spider mites found in Nebraska corn and soybeans, their natural enemies and management.

Two species of spider mites, the Banks grass mite and twospotted spider mite, commonly feed on Nebraska corn. Banks grass mites (BGM) feed almost exclusively on grasses, including corn and sorghum. Twospotted spider mites (TSM) not only feed on many species of grasses, but also on soybeans, fruit trees and a variety of vegetables and ornamental plants. Although these two species are somewhat similar in appearance, they differ in several biological characteristics and in their susceptibility to pesticides.

Banks grass mites …
