18. Summary
BPH population and attacks tend to decline in Indonesia during , as observed in many major rice fields.
Rice virus diseases found fewer than before in the endemic area of BPH.
Even though of low population of BPH in experiment site, the natural enemies existed there in a good population.
Due to the beauty of flowers of Cosmos caudatus, many farmers that visited the experimental site wish to grow it. Later, the Bupati (Head of Regency) Klaten was interested to ask farmers to grow it along the dike of rice plot.

19. Future Plan
: Survey for BPH and its natural enemies, as well as viruses.
: an Experiment for controlling BPH.
: Developing diagnostic kits (using molecular techniques) for rice virus diseases.
