EL HONGO BLANCO [1] PARA EL CONTROL DEL GORGOJO DE LOS ANDES O GUSANERA DE LA PAPA [2]

Qué es el hongo blanco?

El hongo es un microbio (Fig. 1) que enferma y mata al gusano de la papa (Fig. 2) en todas sus formas de desarrollo como larva, pupa y adulto, cubriéndolo de una pulvurulencia blanca (Fig. 3).

El hongo se puede producir en granos enteros o molidos de cebada, arroz, o maíz en bolsas de plástico. EI hongo no ataca a la persona ni a los animales domésticos.

Cómo actua el hongo blanco?

Cuando el hongo se pone en contacto con la superficie del insecto (larva, pupa o adulto) ingresa a travéz de su piel y se desarrolla en su interior (Fig. 4).

Esto generalmente ocurre dentro del suelo que debe estar húmedo para facilitar el desarrollo y la penetración del hongo. Las larvas muertas toman inicialmente un color rosado pero Juego se cubren con el desarrollo del hongo que le da un aspecto algodonoso blanco (Fig. 5).

Cuando los gusanos de la papa han completado su desarrollo, salen de la papa y penetran al suelo para convertirse en pupas y, después, en gorgojos adultos (Fig. 6).

Los gusanos comienzan a salir de la papa un poco antes de la cosecha; y continúan saliendo durante la cosecha, selección y almacenamiento (Fig. 7). Si en este momento el hongo esta presente en el suelo, el gusano es atacado y muere. El gusano es el estado mas susceptible. Algunas larvas enfermas pueden llegar a empupar pero mueren como pupas. Lo importante es asegurarse que el hongo esté en el suelo y que el suelo se mantenga húmedo para asegurar su sobrevivencia.

Qué cantidad y cómo se aplica el hongo?

Por ahora el uso del hongo se restringe a los lugares donde se amontona la papa especialmente en los almacenes. Se está investigando su utilización en el campo. Se usa 2 bolsas (1 kg por bolsa) de producto comercial por metro cuadrado de suelo, en almacenes y lugares de amontonamiento de papa. Las bolsas deben presentar un color blanco pulverulento. (Fig. 8) (Fig. 12)

El suelo a tratar debe estar húmedo (alrededor de su capacidad de campo). Si esta seco se le agrega agua y se deja orear. Luego se pica el suelo superficialmente y con una lampa se retira a un lado una capa de tierra de 5 cm. de grosor. Sobre la superficie que queda se distribuye el hongo (Fig. 9) y se cubre con la tierra que se había retirado previamente. Sobre la superficie así tratada se amontona la papa que se desea seleccionar o almacenar (Fig. 10). A los cuatro meses se puede comprobar el efecto del hongo (Fig. 11).

Qué ventajas tiene el hongo blanco sobre los insecticidas?

• No es tóxico para el hombre ni animales domésticos
  
• Es relativamente específico para la plaga. No afecta a escarabajos benéficos
  
• Es un organismo natural que no contamina el medio ambiente
  
• Una vez que se establece en el suelo, su efecto es duradero en tanto se le mantenga húmedo
  
• Es efectivo y evita que los almacenes de papa se convierten en focos de emergencia de gorgojos que migran a los campos de papa.
