Abstract

Citrus leprosis, one of the most important diseases for the Brazilian citrus industry, is caused by a virus and efficiently transmitted by a polyphagous and cosmopolitan mite. The control of the disease has been heavily focused on the chemical control of the Brevipalpus phoenicis vector, with high costs to the growers and the environment. These costs could be almost certainly reduced if more adequate IPM practices were used in the field. Several breakthroughs in the studies involving this complex pathosystem have been observed in the last 10 years, but on individual components of the system. Regarding the mite, it has been addressed different aspects of its biology, its dispersion within and between orchards, and the presence of an endosymbiont. The pathogen, Citrus leprosis virus (CiLV), can now be detected through molecular tests in planta and in the mite vector, since its whole genome has been sequenced. Furthermore, due to its genomic information, it received a new taxonomic classification. Studies also addressed the CiLV host range, which turned out to be significantly broader than initially thought and include plants that often occur naturally in citrus orchards. These information, however, have not been used so far to improve the management of the disease, which has spread throughout South and Central America during the last years. New strategies to manage leprosis in orchards should take in consideration not only the presence of the mite in endemic regions - the current strategy - but also, and mainly, the presence of the virus in the plants and the vector, the potential of different types of lesions to serve as sources of inoculum, the use of varietal resistance, the role of alternative hosts on the disease epidemiology, the presence and management of natural enemies etc. Hence, the objective of this project is to increase the knowledge on leprosis and optimize the management of the disease, considering all of the components of the pathosystem as well as their interactions.
