- Abstract
Leafhoppers (Hemiptera: Cicadellidae) that inhabit edge grasses throughout the winter were tested for the presence of corn stunt spiroplasma (CSS) and maize bushy stunt phytoplasma (MBSP). Leafhoppers were sampled using a sweep net at least once a week between Feb and Jun 2014 in Jalisco, Mexico. In total, 2,263 leafhoppers from 27 different taxa were collected. Stirellus bicolor Van Duzee and Graminella sonora (Ball) were the most abundant leafhoppers, with smaller numbers of Dalbulus maidis Delong and D. elimatus Ball. None of the leafhoppers tested positive for CSS or MBSP, suggesting that these 2 bacterial pathogens do not overwinter in leafhoppers that live on edge grasses. This is an important finding, because several studies have found that crop edges are beneficial reservoirs of insect predators and parasitoids, including those that attack insect vectors of plant pathogens.
