The family Tuckerellidae, or peacock mites, is a monogeneric group comprising approximately 32 species, which are usually collected from the fruits or woody parts of their host plants. Fruits and branchlets of mamey, Mammea americana L. (Calophyllaceae) trees in north-western Peru were sampled for peacock mites throughout spring and summer for two consecutive years. This is the first record of Tuckerella pavoniformis (Ewing) (Acari: Tuckerellidae) feeding on mamey. Aggregations of mites were much higher and more common on the fruit epicarps than on branchlets. Recommendations for the development of an Integrated Pest Management strategy for this peacock mite are included.

The department of Piura is the main mango producer in Peru accounting for 66.7% of the national crop. The objective of the study was to characterize the fruits of forty varieties of mango preserved since 1969 in northwestern Peru. The fruits were harvested at the El Chira Agrarian Experimental Station, Department of Piura from December 2019 to January 2020. Thirteen quantitative fruit variables were evaluated: width, thickness, length, weight, seed width, seed thickness, seed length, percentage of seed, percentage of fresh skin, percentage of pulp, texture, °Brix, and pulp / seed ratios. The varieties with the highest percentage of pulp were Tommy Atkins, Haden x carabao 1, Irwin, and Jaffra, the latter was also the variety with the highest pulp / seed ratio (17.0). The varieties with the highest ° Brix were Blacman (21.3 ° Brix) and Julie (22.0 ° Brix). Knowledge of the fruit charac...
