Integrated 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...
متن کاملPLANTÐINSECT INTERACTIONS Patterns of Starch Accumulation in Alfalfa Subsequent to Potato Leafhopper (Homoptera: Cicadellidae) Injury
Patterns of starch accumulation in alfalfa,Medicago sativa L., were studied in response to injury causedbypotato leafhopper,Empoasca fabae (Harris).Using image analysis of iodine-stained leaf tissues, we compared lightness scores of leaves from leafhopper-injured and healthy plants sampled at early morning and mid-afternoon. In addition, we related lightness scores to standard chemical analyses...
متن کاملPotato 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 کاملGlandular-haired alfalfa resistance to potato leafhopper (Homoptera: Cicadellidae) and hopperburn: development of resistance indices.
Eight proprietary genotypes of glandular-haired alfalfa, Medicago sativa L., supplied by two different companies, were compared for the degree and types of resistance to the potato leafhopper, Ernpoasca fabae (Harris), and hopperburn. A tube cage no-choice bioassay was developed to test leafhopper mortality, feeding, settling preferences, severity of hopperburn symptoms (in this case, defined a...
متن کاملPhysiological response of glandular-haired alfalfa to potato leafhopper (Hemiptera: Cicadellidae) injury.
Plant tolerance to herbivory is a key approach for managing pests. In alfalfa, Medicago sativa, the potato leafhopper, Empoasca fabae, is a major pest as a result of the cascade of plant responses to piercing-sucking injury. To identify tolerance to its injury based on alfalfa physiology, experiments were conducted in the field and greenhouse. In our comparison of the response of field-grown al...
