Detection of Maize Bushy Stunt Phytoplasma in Leafhoppers Collected in Native Corn Crops Grown at High Elevations in Southeast Mexico

“…because more female leafhoppers were caught than males (Table 1). An excess of female leafhoppers as evidence of immigration previously is described for M. quadrilineatus, E. fabae, and D. elimatus (Drake & Chapman 1965;Emmen et al 2004;Moya-Raygoza et al 2012). The collection dates also may influence the differences between the number of females and males (Pinedo-Escatel & Moya-Raygoza 2015).…”

“…Along with maize bushy stunt phytoplasma, other pathogens are efficiently transmitted by leafhoppers from the genus Dalbulus, such as maize rayado fino virus and corn stunt spiroplasma Spiroplasma kunkeii (Whitcomb et al 1986) (Entomoplasmatales: Spiroplasmataceae) (Moya-Raygoza et al 2012). Together, the 3 pathogens form the corn stunt complex, which is a well-known cause of yield loss in corn production in Central and South America.…”

Exitianus obscurinervis (Hemiptera: Cicadellidae), a New Experimental Vector of Spiroplasma kunkelii

“…An analysis of body size differences (Moya-Raygoza et al 2007, 2012 suggested that D. maidis and D. elimatus adults can move both locally and over long distances. Dalbulus maidis adults infected with CSS could have migrated to high-elevation sites such as Zapopan from low-elevation sites (less than 1,000 m) elsewhere in Mexico where maize is cultivated (Moya-Raygoza et al 2007).…”
