Factors influencing aster leafhopper (Hemiptera: Cicadellidae) abundance and aster yellows phytoplasma infectivity in Wisconsin carrot fields.
In Wisconsin, vegetable crops are threatened annually by infection of the aster yellows phytoplasma (AYp), the causal agent of aster yellows (AY) disease, vectored by the aster leafhopper, Macrosteles quadrilineatus Forbes. Aster leafhopper abundance and infectivity are influenced by processes operating across different temporal and spatial scales. We applied a multilevel modeling approach to p...
متن کاملOverwintering non-crop sources of aster yellows phytoplasma
Research Overview: This project is directed at further enhancing our present understanding of the epidemiology and overwintering biology of the aster yellows phytoplasma (AYp) with a focus on factors that influence its geographical distribution in the upper Midwest and spread into Wisconsin muck crops. Our current research program focuses on: 1) generating new information about the identity, ge...

متن کاملSeasonal Infectivity of Aster Leafhoppers in Carrot
Problem Defined: Each year, Wisconsin growers produce carrots on an average of 4200 acres grossing over $6 million dollars in revenues (USDA-NASS, 2007 annual bulletin). Unfortunately, carrot fields are threatened annually by the occurrence of aster yellows phytoplasma (AYp), which is obligately transmitted by the aster leafhopper (Macrosteles quadrilineatus Forbes). Current control practices s...
