Abstract


Efforts to increase crop production often faced difficulty with pests and diseases. The use of high yielding varieties can be an alternative control. This study aimed to determine the population and intensity of pest damage Plutella xylostella on five varieties of cabbage (Brassica oleraceae L.). The experiment was conducted in the village Waipirit in October 2012 until January 2013. The study was designed using a randomized block design with five treatments, namely cabbage as the Grand 11, KK-Cross, Green Coronet, Green Hero, and Investor.
