Incidencia de las plagas de lepidópteros en el cultivo de Brassica oleracea

Abstract

[ES] El cultivo de Brassica oleracea (L.) está ampliamente distribuido en el Noroeste de España. En estas condiciones, los daños ocasionados por diferentes plagas de insectos pueden llegar a ser importantes. El objetivo•de este trabajo consistió en identificar las distintas especies de lepidópteros presentes en el cultivo de B. oleracea en Galicia para conocer su abundancia relativa y su importancia a la hora de diseñar un programa de mejora y de manejo integrado de plagas. Se utilizaron trampas de feromonas sexuales para la captura de adultos y las poblaciones larvarias se estimaron mediante conteos de larvas durante los meses comprendidos entre mayo y diciembre de 1999. En este periodo, la especie más abundante fue el noctuido Mamestra brassicae (L.), pudiendo considerarse esta especie como la principal plaga en Galicia. También se encontraron, aunque en menor frecuencia, larvas de Pieris rapae (L.) y Pieris brassicae (L.).

[EN] Brassica olemcea (L.) is a widely spread culture in northwestern Spain, which is affected by different pests causing significant damage. The objective of this study was to identify the species of injurious lepidopterous attacking this culture in Galicia to asses their importance and relative abundance in order to design a breeding program based on the search for resistant germplasm. Sex pheromone traps were used to collect adults and larval populations were estimated by counting the larvae in the field from May to December 1999. The most abundant species was the noctuid Mamestra brassicae, which may be considered the major pest. Pieris rapae and Pieris brassicae larvae were also found, although in lower frequencies.
