Dalbulus maidis represents one of the main pests of corn in tropical and subtropical areas, including the north of Argentina. It is a vector of four pathogens: 1) Spiroplasma kunkelii, causing the disease Corn Stunt Spiroplasma (CSS) 2) Maize phytoplasma, caused by Candidatus Phytoplasma asteris, causing the disease Maize bushy stunt phytoplasma (MBSP) 3) Maize rough dwarf virus (MRFV) 4) Maize striate mosaic virus (Mastrevirus, Geminiviridae). The first three cause maize stunting, an endemic disease and the most important one in northern Argentina. Once the sharpshooters acquire the pathogen, they remain infectious throughout their entire life.
It is a phytophagous species, practically monophagous or specialist, as it feeds almost exclusively on plants of the genus Zea, including corn (Z. mays L.) and its wild ancestors (teosintes). It is only capable of completing its development and reproducing on these plant species.
In Argentina, it is the most common species in cornfields north of the 30ºS parallel (Paradell et al. 2001, Remes Lenicov & Paradell 2012).
