17. 2. Monitoring of planthoppers with yellow sticky traps

19. 3. survey results for Rice plant hoppers, rice viruses and plant species

20. There had no more serious of Planthoppers (GPH, BPH, WPH and ZPH)or virus outbreak in three provinces where were surveyed, but there had only more population of Green planthopper, they didn’t damage rice plant.
The peak migration time in planthopper was from half February to last March, but it was not serious in the rice field. There was also had not the peak occurrence time in rice viruses in rice plant areas.

21. Project plan
Continue to Survey for rice planthopper and viruses infection of rice plant, monitoring of planthoppers with light trap and monitoring of planthoppers with yellow sticky traps.
Publish as newspaper, newsletter, booklets,
etc of the research results to every part of the country, especially the locations where have rice production.
