稻虱缨小蜂类Anngrus spp.是褐稻虱卵期重要寄生性天敌。福建沙县早稻本田、晚稻秧田及本田褐稻虱卵寄生率分别为35.1,29.1,20.1％;江苏东台县弶港农场直播稻田9月上、中旬田间褐稻虱卵寄生率达32.47—55.64％。为进一步探明其在稻田的种群消长规律及其对褐稻虱田间种群数量的控制能力,从而为组建天敌子模型以及进而组建褐稻虱田间种群动态预测模型和管理模型提供参数估值。作者在1984—1986三年间,首先对稻虱缨小蜂Anagrus nilaParvatae Pang et Wang成虫生物学进行了较为系统的研究。
Anaphoris spp., An important parasitic natural enemy of the brown planthopper in egg stage. Fujian Shaxian early rice Honda, late rice seedling and Honda brown planthopper egg parasitism rates were 35.1,29.1,20.1%; Jiangsu Dongtai Xingang farm direct seeding rice fields in September, mid-brown rice louse egg parasitization rate of 32.47-55.64%. In order to further ascertain its population dynamics and its controlling ability to the brown planthopper population in the paddy field, this paper provides the parameter estimation for establishing the natural enemy animal model and further establishing the dynamic prediction model and management model of the brown planthopper population. In the three years from 1984 to 1986, the author first conducted a systematic study on adult biology of Anagrus nila Parvatae Pang et Wang.
