Brevipalpus mites associated with coffee plants (Coffea arabica and C. canephora) in Chiapas, Mexico
Tenuipalpid mites of the genus Brevipalpus are of signifcant economic and quarantine importance in agriculture. They can damage and vector phytopathogenic viruses in cofee plantations and other crops. In this study, we focused on: identifcation of the Brevipal pus species, assessment of the spread of Brevipalpus-associated viruses (CoRSV, CiLV-N, CiLVC and CiLVC2), and mite population fuctuations over the course of 1 year. The study was conducted in cofee plantations in Soconusco, a cofee-producing region in Chiapas, Mexico. The collected mites of the Brevipalpus phoenicis sensu lato species complex (635) were identifed as Brevipalpus papayensis (80.2%) and B. yothersi (19.8%) based on morphological and molecular characteristics. Their population abundance was low and there were no indications for virosis. The highest mite abundance was recorded in August–September and the lowest in February–March. An interaction was observed between mite abundance and cofee species in open-growth and shaded cultivation at various altitudes. Brevipalpus papayensis was most abundant in Cofea arabica var. Bourbon, in shaded (80%) growing conditions at an altitude of 1300 m above sea level. In C. canephora (in open-growth cultivation conditions at low altitude), B. yothersi was more abundant than in C. arabica, and as abundant as B. papayensis. We are of the opinion that, at this moment, B. papayensis and B. yothersi do not present risks to the production of cofee for the stud ied plantations. However, as the cofee-producing regions of Mexico are ecologically diverse, it will be important to continue examining the status of Brevipalpus mite populations in other regions in Mexico.
