摘　　要：利用寄生变红卵和仔代成蜂数量作为繁殖力估计等方法,编制了稻虱缨小蜂(Anagrus nilaparvataepang and wang)在褐飞虱(Nilaparvata lugens(Stal))卵和白背飞虱(Sogatella furcifera(Horvath))卵上繁殖的实验种群生命表,测定了稻虱缨小蜂寄生褐飞虱和白背飞虱的生殖力,分析了稻虱缨小蜂对稻飞虱卵的寄生能力。结果表明:在相同的繁蜂条件下,稻虱缨小蜂寄生褐飞虱卵的净生殖力R0为10.26,内禀增长率rm为0.2213,平均单雌产仔数为14.52头;寄生白背飞虱卵的净生殖力R0为8.78,内禀增长率rm为0.1840,平均单雌产仔数为12.20头。两组生命表参数比较分析显示褐飞虱卵具有较强的室内繁蜂潜能,可利用其进行室内繁蜂。应用稻虱缨小蜂、褐飞虱及白背飞虱的生命表参数讨论了稻虱缨小蜂在稻飞虱生物防治中的应用潜能及其可能的利用途径。The experimental population of A.nilaparvatae was reared separately in the eggs of N.lugens and S.furcifera to study the life table.Fecundity was estimated by the number of reddened parasitized eggs or progeny adults.It was followed by the study of its parasitic ability to the eggs of rice hopper.Population rearing,characters were compared by experimental population life tables on the eggs of N.lugens and S.furcifera.The parameters of the life table studied on the eggs of N.lugens were as follows： R0=10.26,T=10.52（day）,rm=0.2213,λ=1.2477,P♀=0.7065,R′0=R0/ P♀=14.52;where as the values of different parameters of life table studied on the eggs of S.furcifera remained at： R0=8.78,T=11.81（day）,rm=0.1840,λ=1.2020,P♀=0.7191,R′0=R0/ P♀=12.2032.These results showed that the eggs of N.lugens were suitable for the rearing of A.nilaparvatae as compared to the eggs of S.furcifera.This study also provides adequate information about the application potential of A.nilaparvatae in the rice against rice pests that can be helpful in the production of organic rice with better quality.
