Plutella xylsotella: Bioecología y control

Abstract

La polilla o palomita de las coles o del dorso de diamante, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae) es un insecto herbívoro oligófago y el más dañino dentro de los complejos de plagas que atacan los cultivos de Brassicaceae en todas las regiones productoras del mundo. Los costos de manejo y las pérdidas ocasionadas a los cultivos por esta plaga fueron estimados recientemente en U$S 4.000 a 5.000 millones por año a nivel mundial. La importancia económica de P. xylostella es generalmente mayor en las regiones tropicales, subtropicales y en las partes más cálidas de la región templada, por la menor duración de su ciclo de vida y el cultivo de brásicas a lo largo de todo el año (Furlong et al., 2013;Grzywacz et al., 2010; Li et al., 2016; Conte de Oliveira et al., 2011; Sarfraz, 2014;Shelton, 2004; Talekar y Shelton 1993; Zalucki et al., 2012). Se ha sugerido y es ampliamente aceptado que se originó en la región mediterránea o Asia Menor por considerarse los lugares de origen de las principales especies de crucíferas cultivadas, por la presencia de un complejo de enemigos naturales y por no haber desarrollado un estado de diapausa resistente a bajas temperaturas (Hardy,1938). Más recientemente, Kfir (1998) y Liu et al. (2000) proponen como centro de origen a Sudáfrica o China, respectivamente, sobre la base de las numerosas plantas hospedantes silvestres endémicas y de la riqueza y diversidad de la fauna de parasitoides nativos presentes en esas regiones.
