fajas de cartón corrugadoEl Ministerio de Producción advirtió que colocar bandas corrugadas de diez a 15 centímetros de ancho en árboles y parcelas, a partir de enero, sirve como trampa contra las larvas invernantes de carpocapsa y grafolita que afectan a frutales de carozo y pepita. Esto, porque las larvas bajan del árbol y se introducen en las canaletas del cartón. Este método es efectivo, de fácil instalación, y con bajos costo de implementación e impacto ambiental.

El Ministerio de Producción, a través del Instituto de Sanidad y Calidad Agropecuaria Mendoza (Iscamén), les advirtió a los trabajadores rurales que pueden reducir la carga de larvas invernantes de carpocapsa y grafolita que afecta a frutales de carozo y pepita colocando fajas de cartón corrugado en árboles y parcelas a partir de enero.

Estas bandas trampa son una herramienta efectiva, de fácil instalación, bajo costo de implementación y bajo impacto ambiental. Su utilización ayuda a disminuir las poblaciones de estas plagas, ya que las larvas bajan del árbol y se introducen en las canaletas del cartón. Estos cartones deben retirarse desde fines de abril hasta junio.

faja de cartón corrugado Las bandas trampa son tiras o fajas de cartón corrugado, de entre diez y 15 centímetros de ancho. Normalmente se utilizan los sobrantes del cartón empleado en el embalaje, ya que cualquier tipo de corrugado funciona como trampa para esas plagas.

Cuando la larva de cualquiera de las dos plagas se “tira” de la fruta para empupar, confunde la corteza del árbol con la

trampa de cartón. Por eso es posible, después de un tiempo, encontrar los cartones con larvas invernantes. Así, correctamente

utilizados, disminuyen la población de plagas presentes en el monte.

Formas de colocación

En la parcela: en las dos primeras hileras perimetrales de la parcela se deben colocar bandas trampa en todos los árboles.

Dentro de la parcela se colocan árbol por medio e hilera por medio.

faja de cartón corrugado En el árbol: las “tiras” de cartón corrugado deben colocarse envolviendo el tronco del árbol a unos 30 centímetros del suelo; también se pueden colocar en las ramas primarias. Se debe raspar el tronco y luego colocar las bandas envolviéndolo, de forma que las partes corrugadas del cartón queden enfrentadas entre sí, sosteniéndose con grampas o alambre.
