Cochinillas presentes en viñedos de Colonia Caroya, Córdoba, Argentina. Incidencia en el cultivo y efectos sobre la calidad de los mostos

Abstract: En viñedos de Colonia Caroya, Córdoba, se ha observado un incremento de la población de cochinillas a partir de 2001-2002. El objetivo del trabajo fue determinar las especies presentes, su incidencia en viñedos de la zona y sus efectos sobre calidad de mostos. Para identificar las especies se recolectó material vegetal de variedades tintas y blancas; se cuantificó la incidencia y la intensidad de la especie más abundante en 15 viñedos en 2010 y 2011 y se determinó el efecto de las cochinillas sobre la calidad … Show more

“…The vine mealybug, Planococcus ficus Signoret (Hemiptera: Pseudococcidae), is an invasive phloem-feeding insect from the Mediterranean area, which has become a serious pest in many grape-growing regions worldwide (Daane et al,2012;Mansour et al, 2017;. In Argentinian vineyards, P. ficus was first detected in 2001, although it might have been present earlier, and it has spread across all grape-growing provinces of the country (Becerra et al, 2006;Viglianco et al, 2016). The problem is aggravated by the presence of the invasive Argentine ant Linepithema humile Mayr (Schulze-Sylvester et al, 2018), a common mutualist of P. ficus, which can increase mealybug densities on grapevine (Vitis vinifera L.) plants and clusters by 2-to 80-fold (Daane et al, 2007;Mgocheki and Addison, 2010).…”

“…The honeydew excreted by mealybugs promotes the growth of sooty mould on leaves and fruits, reducing leaf photosynthesis and grape marketability (Daane et al, 2012). Mealybug infestation has also been shown to affect wine and must quality, but the underlying mechanism is unclear; it may be linked to the presence of mealybugs in the grape bunches (i.e., the "mealybug flavour"), to the honeydew and fungus associated with their feeding, or to changes in the plant's physiology (Bordeu et al, 2012;Chiotta et al, 2010;Viglianco et al, 2016). Moreover, viral plant diseases, such as the grapevine leafroll-associated virus (GLRaV) which can be vectored by mealybugs, have also been shown to reduce crop yield and wine quality (Herrbach et al, 2017).…”
