Cómo aprovechar el lenguaje de las plantas para mejorar el control de plagas en tomate

Abstract

En los últimos años, el uso de míridos depredadores (Hemiptera: Miridae) en cultivos de invernadero ha aumentado considerablemente. Además de su elevada eficacia como agentes de control biológico sobre un amplio rango de presas, en los últimos años se ha comprobado que su fitofagia puede inducir respuestas de defensa en las plantas sobre las que se alimenta. Se ha demostrado cómo una planta activada defensivamente por la alimentación de míridos emite volátiles que son repelentes frente a varias especies plaga y atractiva sobre enemigos naturales. También se ha demostrado que estas defensas inducidas son capaces de reducir la reproducción y desarrollo de fitófagos y la multiplicación de virus. Además, una planta de tomate activada defensivamente por míridos puede alertar a plantas intactas que se encuentren en su proximidad mediante la comunicación por volátiles, y éstas entrar en un estado de alerta (priming) y activar mecanismos de defensa mediados por la ruta del ácido jasmónico. Recientemente hemos identificado qué volátiles son los responsables de esta inducción por comunicación. En este trabajo se presentan varias aproximaciones de cómo utilizar estos volátiles en programas de manejo de plagas cómo elicitores de defensa en el cultivo de tomate.
