Front cover: This photo shows larvae of Andraca bipunctata Walker (Lepidoptera: Bombycidae) and their predator Eocanthecona concinna (Walker) (Hemiptera: Pentatomidae). A. bipunctata is widely distributed in main production areas of Camellia oleifera and tea in southern China, and its larvae feed gregariously on leaves of C. oleifera, C. sinensis, C. japomica, etc. E. concinna starts to prey at the 3rd instar. Under the ratio of the natural enemy to prey by 5:40, the controlling effect of E. concinna nymphs on A. bipunctata larvae was as high as 39.3%.
