Abstract
En el Perú las áreas para la producción de cítricos (mandarinas, tangelos, naranjas, limones y toronjas) se concentra en la costa peruana siendo la mandarina la más cultivada en sus distintas variedades, en cuanto a la producción nacional de mandarina: Lima es el que posee el 57% de la producción total, seguido de Ica con un 22%. (MINAGRI, 2014). La costa peruana presenta condiciones agroclimáticas como son temperaturas cálidas y alta humedad que son condiciones favorables para el desarrollo del ácaro del tostado Phyllocoptruta oleivora (Ashmead), cuyo daño ocasiona el manchado o bronceado en la fruta y afecta la calidad interna del fruto donde la concentración de azucares incrementa por la pérdida de agua a causa de las picaduras. En el manejo integrado de plagas; se han de emplear distintas estrategias y técnicas. Uno de ellos es la poda es un control físico donde se elimina ramas de poco vigor y de baja productividad para lograr un buen ingreso de luz al interior de árbol; por otro lado, el control cultural del lavado de plantas ayuda a eliminar la presencia de polvo en follaje, la de líquenes en las ramas y tronco. En el control químico los umbrales de acción nos indican el momento adecuado para el uso de acaricidas, estos valores se obtienen de las evaluaciones del ácaro del tostado, y a partir de ello elaborar la fluctuación poblacional que mostrará los periodos críticos para el control de Phyllooptruta oleivora. Todas estas estrategias en conjunto ayudan al adecuado manejo sanitario del acaro del tostado.
In Peru, citrus production areas (mandarins, tangelos, oranges, lemons and grapefruit) are concentrated on the Peruvian coast, with mandarins being the most cultivated in their different varieties. In terms of national mandarin production: Lima has 57% of total production, followed by Ica with 22% (MINAGRI, 2014). The Peruvian coast presents agroclimatic conditions such as warm temperatures and high humidity, which are favorable conditions for the development of the citrus rust mite Phyllocoptruta oleivora (Ashmead), whose damage causes staining or tanning in the fruit and affects the internal quality of the fruit where the concentration of sugars increases due to the loss of water because of the bites. In integrated pest management, different strategies and techniques have to be used. One of them is pruning, which is a physical control that eliminates branches of low vigor and low productivity to achieve a good entry of light into the tree; on the other hand, the cultural control of washing plants helps to eliminate the presence of dust on foliage, lichens on the branches and trunk. In chemical control, the action thresholds indicate the appropriate moment for the use of acaricides, these values are obtained from the evaluations of the toast mite, and from this to elaborate the population fluctuation that will show the critical periods for the control of Phyllooptruta oleivora. All these strategies together help in the adequate sanitary management of the citrus rust mite.
