The aim of this study was to evaluate the natural infectivity of Dalbulus maidis with spiroplasma (corn stunt spiroplasma'CSS'Spiroplasma kunkelii), phytoplasma (maize bushy stunt phytoplasma'MBSP), and virus (maize rayado fino virus'MRFV) through transmission tests using two densities of leafhoppers (one and five adult D. maidis) collected fortnightly from maize fields during two agricultural years. During 35 months D. maidis adults were collected in maize at intervals of 15 days with entomological net (Sete Lagoas/MG, Brazil). The leafhoppers were confined in number of one or five individuals by maize plant (V2 stage) for an inoculation access period (IAP) of five days. At flowering stage, plant disease symptoms were evaluated. The total percentage of plants showing symptoms of infection by at least one of the pathogens (spiroplasma, phytoplasma or MRFV) was significantly higher for plants that were exposed to five leafhoppers (24.2%) compared to those exposed to one leafhopper (12.3%). The percent of diseased plants was similar in Autumn (20.0%), Winter (18.8%), Springer (16.1%) and Summer (18.3%). However, spiroplasma infection was predominant in Summer. Our results demonstrated that a five-fold increase in the number of D. maidis on maize plants led to a two-fold increase in the number of symptomatic plants. Under natural conditions, leafhoppers have the ability to visit multiple plants during the post-emergence phase, thereby transmitting pathogens to multiple plants that become source plants for corn stunt and virus diseases. Therefore, population reduction of D. maidis can be a critical strategy for managing these diseases in maize crops.
