Abstract: Hopper egg parasitoid communities in rice field were made up of Mymaridae and Trichogrammatidae. Anagrus ,which belonged to Mymaridae was the most numerous genus in the communities.In order of number: Anagrus>Gonatocerus>Neurotes>Mymar.The percentage of Trichogrammatidae was always low.The parasitiods of Mymaridae were the dominant natural enemies to rice hoppers,and had higher percentage in IPM rice fields than that in non IPM ones.The dynamics of the communities had close relationship with the growth of rice,and could be divided into three steps: reestablishment,development and collapse.The hopper egg parasitoid communities in IPM rice fields reestablished more quickly,developed more steadily,and collapsed more gently than those in non IPM ones.

Key words: cotton, boll period, increased temperature, functional leaf, photosynthesis.
