6. For the life cycle of nematode , there is only one stage to eliminate the insects: Infective Juvenile (IJ). The most efficiency of eliminating insects is Steinernema carpocapsae. Introduction
7. There is, in nematode intestine, symbiosis bacteria Xenorhabdus nematophila . This bacteria produces some substances that can eliminate insects. Introduction
8. Developing methods to eliminate Coptotermes curvignathus by using nematode Introduction
9. To study efficiency of nematode and bacteria from the entomopathogenic nematode to eliminate termite in para rubber Objective Para rubber

Good morning. Ladies and Gentlemen. My name is … and … . We come form mahidol Wittayanusorn school Thailand. Today we would like to present our project. The title is Efficiency of nematode ( Steinernema carpocapsae ) and symbiosis bacterium Xenorhabdus nematophila from the entomopathogenic nematode for eliminating termite Coptotermes curvignathus in Para Rubber. Now we would like all of you to know about the background and introduction of our work.
