This book aims to convey knowledge about the seasonal frequency of the cabbage moth and the ladybug in the cabbage ecosystem. The cabbage moth is one of the most resistant insects to conventional insecticides. In addition to the usual management aspects and methods, this chapter presents advanced control methods using novel insecticides against the cabbage moth that are safe for natural enemies in the cabbage ecosystem. Every effort has been made to assess the effectiveness of newer insecticidal molecules against DBM, and the results are expected to be helpful in combating Plutella xylostella.
