Miscelanea 152 (2024): Dalbulus maidis (Hemiptera: Cicadellidae), vector of corn stunt disease: Relevant biological aspects, with special reference to knowledge generated in Argentina

Abstract

Due to its frequency, abundance in crops, and remarkable capacity to efficiently transmit at least four pathogens, Dalbulus maidis stands out as one of the most significant threats to maize crops in Latin America. The recent population outbreak of this pests observed in Argentina has highlighted its potential to cause significant damage to maize crops, with estimated losses reaching up to 80%. Consequently, one of the most pressing needs is to integrate and disseminate fundamental knowledge on various bioecological aspects of this vector to researchers, technicians and stakeholders interested in maize crop health. This contribution is a summary of the knowledge on the main biological characteristics of the vector acquired over more than 50 years. Among other topics, the provided information encompasses its identification, biological traits, distribution, pest significance, life cycle and development, voltinism, host plants, behaviors, and natural enemies. All this information is crucial for developing an effective pest management program in Argentina.
