Utilizing Natural Biological Control for Cotton Aphids: Cotton Aphid Fungus Sampling Service Twelfth Year

摘要

RESEARCH PROBLEM - Cotton aphids, Aphis gossypii, have been a persistent problem in cotton aphid production for the past 16 years. Each year since 1988 the fungus, Neozygites frese-nii, has terminated aphid populations in many fields throughout Arkansas, Alabama, Georgia, Mississippi, Louisiana, South Carolina, and North Carolina. The Cotton Aphid Fungus Sampling Service, supported by Cotton Incorporated, has played a valuable role in helping growers, extension agents, and consultants determine whenthe fungus would terminate aphid problems in fields, counties, and states. The service completed its twelfth year of assisting the cotton community in 2004.
