| Abstract: | The species composition of the rice stem borer and the species parasitic rate of natural enemy on the eggs of Tryporyza incertulas were studied by investigating different rice areas in Guangdong.The results showed that Tryporyza incertulas was still the predominance species of the rice stem borers;and the proportion of Chilo suppressalis were high in some areas.The Thehmpmma sp.was the main parasitic natural enemy on the eggs of Tryporyza incertulas,and its parasitic rate was low. |
