摘要
通过对广东不同稻区钻蛀性螟虫和三化螟卵寄生性天敌资源的调查,结果表明:三化螟仍是稻区钻蛀性螟虫的优势种群,二化螟在个别地区比例较大;三化螟卵寄生性天敌以稻螟赤眼蜂为主,卵寄生率较低。
The species composition of the rice stem borer and the species parasitic rate of natural enemy on the eggs of Tryporza 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.
