Characterization of fruits of varieties of mango (Mangifera indica) conserved in Peru
(Sociedade Brasileira de Fruticultura, 2021-04-23) Tuisima Coral, Lady Laura; Escobar García, Héctor Alonso
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 characteristics is essential for proper selection and use by the industry, especially those with a higher pulp weight to obtaining higher yields in processing.

Manual técnico para la conservación y propagación de especies de algarrobo (Prosopis spp.)
(Instituto Nacional de Innovación Agraria, 2020-12) Carrillo Castillo, Fredesvinda; García Cochagne, Judith; Cabrera Pintado, Rosa María; Vásquez Oroya, Jhair; Tuisima Coral, Lady Laura; Escobar García, Héctor Alonso; Aguirre Gil, Oniel Jeremías; Quintana Palacios, Cristina; Amasifuen Guerra, Carlos Alberto
El Ministerio de Desarrollo Agrario y Riego (MIDAGRI) a través del Instituto Nacional de Innovación Agraria (INIA) tiene la misión de conservar los recursos genéticos de uso agrario, y fomentar su puesta en valor y producción. Por lo tanto, se vienen desarrollando investigaciones enfocadas en mitigar la disminución poblacional de algarrobo y de esta forma, contribuir en la recuperación de los ecosistemas de bosques secos del Perú. El presente manual proporciona información relevante sobre la propagación y conservación de las especies de algarrobo, se ha elaborado en base a literatura científica referida a las especies identificadas como P. pallida, P. chilensis, P. alba, P. laevigata, P. flexuosa, P. kuntzei, P. limensis, P. nigra, P. glandulosa, P. juliflora, P. tamarugo y P. spicigera. Asimismo, se ha tomado en cuenta información generada en los trabajos de conservación, micropropagación e identificación de plagas, que se han venido realizando en el INIA. En este manual se describen las características botánicas y agroecológicas del algarrobo, se proporciona información relevante respecto a las plagas asociadas a esta planta, y se describen las técnicas de selección, propagación y conservación de las semillas, que permite asegurar el mantenimiento de material vegetal representativo de su variabilidad genética, para su conservación.
Preliminary survey, diversity, and population density of mites in banana, Musa AAA (Cavendish subgroup) cv. Williams in Peru
(Taylor & Francis, 2021-02-01) Escobar García, Héctor Alonso; Andrade, Daniel Junior
Banana is produced mainly by smallholder farmers and considered a staple food in many developing countries. This study aimed to evaluate the diversity and population densities of mites in plants of Musa AAA (Cavendish subgroup) cv. Williams in Peru. Mites were collected every fortnight for 14 months (February 2016 to March 2017) from a banana crop system located at the Universidad Nacional de Piura, northwestern Peru. The following species were found: Tetranychus abacae (Tetranychidae), Neoseiulus fallacoides and Euseius concordis (Phytoseiidae). This is the first report for T. abacae and N. fallacoides in Peru. The most abundant mite was T. abacae, which was found in all evaluations and had the lowest populations between June and August, corresponding to the winter time locally. Both N. fallacoides and E. concordis were found in very low numbers. Knowing mite species in banana plants is essential for a proper crop management, mainly for pest control strategies.
Report of Tuckerella pavoniformis (Acari: Tuckerellidae) on Mamey, Mammea americana (Calophyllaceae), in Northwestern Peru
(MDPI, 2022-05-18) Escobar García, Héctor Alonso; Beard, Jennifer J.; Ochoa, Ronald
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.
