Abstract. A 3-yr study was conducted in California’s southern San Joaquin Valley to determine the overwintering survival of the corn leafhopper, Dalbulus maidis. The corn leafhopper, Dalbulus maidis (Delong and Wolcott) is found only in subtropical and tropical areas of America. Its host range is limited to maize and its . The corn leafhopper, Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Cicadellidae), is one of the most important pests of corn, Zea mays L. (Poaceae), in Latin.

Little information has been published on the control of the corn leafhopper and the corn stunting diseases it transmits. Control tactics can be directed at the vector, the pathogens, or both. Chemical Control Due to the variable regulations around de- registration of pesticides, we are for the moment not including any specific chemical control recommendations.
For further information, we recommend you visit the following resources: EU pesticides database www. However, the leafhopper is a significant pest as a vector of three stunting pathogens: At least one, if not all three, of these pathogens have been reported present wherever the corn leafhopper is found.
The diseases are frequently reported occurring sporadically in many regions but can cause widespread and serious disease in newly introduced, non-adapted maize varieties and maixis where maize is grown throughout the year, with irrigation during the dry season. Damage to maize is most severe when plants are inoculated at the seedling stage, however, grain yield may significantly decrease even when plants are infected at the leaf stage Massola et al.
All three stunting pathogens are persistently transmitted by the dallbulus leafhopper; once an insect becomes a vector, it transmits for life.
The pathogens multiply in the vector and undergo a latent period; after the corn leafhopper acquires the pathogen by feeding on an infected plant, a period of 2 weeks for MRFV, and weeks for CSS and MBSP, must maiids before vectors become inoculative.
