Mites associated with blackberry (Rubus sp. cv. Tupy) in two areas of Michoacan, México

Abstract

Damage caused by phytophagous mites is one of the main phytosanitary problems on blackberry crop. The mite species identification is a very significant activity to implement a program of integrated pest management. The aim of this study was to identify the species of phytophagous mites, predators, and other mites associated with blackberry crop in two locations of Michoacan, Mexico. The research was performed in two blackberry orchards located at Ziracuaretiro and Tacambaro municipalities, which had different type of management: conventional and non-conventional, respectively. In each orchard, 18 samples were collected at 15 d-intervals during an annual cycle, from June 2015 to May 2016. The collected mites were mounted in permanent slide for their taxonomic determination with specific keys with specific keys. Seventeen mite species belonging to ten families were identified, which six were phytophagous species, six were predatory, and five had varied habits. Six of the 17 taxa identified are new records of mites associated with blackberry crop. Most of the mites were collected in the conventional crop (65.4 %), while the abundance of predator mites was highest in the no-conventional crop.

Trap colour and aggregation pheromone dose affect the catch of western flower thrips in blackberry crops

“…This insect feeds on approximately 500 plant species, some of them of economic importance (Badillo‐Vargas et al., 2012; Margaria et al., 2014; Morse & Hoddle, 2006; Ogada, Maiss, & Poehling, 2013; Tzanetakis, Guzmán‐Baeny, VanEsbroeck, Fernandez, & Martin, 2009). In Mexico, this species is considered one of the main insect pests of avocado (Bravo‐Pérez et al., 2018; Ramírez‐Dávila, Solares‐Alonso, Figueroa‐Figueroa, & Sánchez‐Pale, 2013) and soft fruits (Ayala‐Ortega et al., 2019; Cubillos‐Salamanca et al., 2020). Adults and larvae scrape and suck the cell fluids on the surface of leaves and flower petals, causing visible streaks and discolourations, and necrosis of the flower petals, respectively (Castañeda‐González, Johansen‐Naime, Hernández‐Vásquez, & Aparicio‐Parra, 2011; Castresana et al., 2008).…”

Distribución espacial y fluctuación poblacional de familias de ácaros asociados a plantas de zarzamora silvestre (Rubusfruticosits L.)

“…Los estudios referentes a familias y especies de ácaros asociados al cultivo zarzamora son escasos, mientras que aquellos que viven en plantas de zarzamora silvestre son inexistentes. En un estudio realizado en Brasil, Marchetti y Ferla (2011) reportan 12 familias de ácaros asociados al cultivo, mientras que en México, en dos municipios de Michoacán, Ayala-Ortega et al (2019) encontraron un total de 10 familias asociadas. La identificación de ácaros asociados al cultivo de zarzamora es fundamental para conocer su diversidad y dinámica poblacional, y resulta útil también para determinar las especies que pueden ser consideradas como plagas para el cultivo.…”
