Transmission of maize bushy stunt phytoplasma by Dalbulus maidis leafhopper

摘要

The maize bushy stunt phytoplasma (MBS) transmission by Dalbulus maidis was studied using two colonies of leafhoppers caged for five days in two MBS symptomatic plants. After the latent period, one leafhopper was confined per seedling in two different maize genotypes (popcorn hybrid and L22 inbred line). Leafhoppers samples were submitted to PCR analyzes before and after inoculation. Colony 1 and 2 had 27.5% and 3.3% of infected leafhoppers, respectively. Maize bushy stunt phytoplasma transmission to popcorn was almost 100% and around 30% to L22.
