Potato Leafhopper (Hemiptera: Cicadellidae) Ecology and Integrated PestManagement Focused on Alfalfa
This article summarizes the knowledge to date on biology of the potato leafhopper, Empoasca fabae (Harris), including its distribution, development, migration, agricultural host plants, and mechanics of injury to host plants. Damage to alfalfa, potatoes, soybeans, and snap beans, and treatment guidelines, are summarized. Particular attention is given to integrated pest management options in alf...
متن کاملVariation in tolerance and resistance to the leafhopper Empoasca fabae (Hemiptera: Cicadellidae) among potato cultivars: implications for action thresholds.
The potato leafhopper, Empoasca fabae (Harris) (Hemiptera: Cicadellidae), is an emerging pest of potato and insecticide applications to control this insect have increased in recent years. Based on field observations of leafhopper-crop dynamics, however, currently recommended action thresholds seem to be overly conservative. As a result, we initiated two experiments designed to quantify the impa...
متن کاملPopulation Dynamics of Empoasca fabae (Hemiptera: Cicadellidae) in Central Iowa Alfalfa Fields
Adults and nymphs of Empoasca fabae Harris (Hemiptera: Cicadellidae) and adults of predatory species in the families Coccinellidae, Anthocoridae, Nabidae, Chrysopidae, and Hemerobiidae were sampled in Iowa alfalfa fields from June to September in 1999 and 2000. The relationship between each predatory taxa and E. fabae was examined using regression analysis. In 2000, all predators were found to ...

متن کاملIntegrated Management of the Potato Leafhopper in Alfalfa
A fully developed integrated pest management (IPM) system uses all available strategies for a given pest or pest complex in a cropping system; incorporating host plant resistance, biological, cultural and physical controls and chemical control when necessary (Pedigo, 1999). Several such management strategies have been developed in alfalfa for the potato leafhopper (Empoasca fabae) (PLH). The fi...
