A home made spray system was used on insecticide experiment on parasitic wasp, Anastatus japonicus Ashmead. This system was associated with bioclimatic chambers to provid a series simulated farm conditions for the experiment of testing the insecticide toxicity on A.

根据生产的需要，研制实用仿真农药喷雾实验系统，配以一定数量的大功率人工设备，并以几种典型的常用农药为例，探讨荔枝蝽卵平腹小蜂在仿真喷雾条件下死亡率与农药田间使用浓度的再稀释浓度的关系。

The biological characteristics and parameters for different geographic populations of Anastatus japonicus Ashmead in the eggs of Antherea pernyi were compared with the method of life table. The results show that the fecundity properties parameters of Vietnamese population including the net reproduction rate (R0), intrinsic rate of increase, finite rate of increase, doubling time, number of eggs laid per female, preoviposition period and oviposition period are superior to Guangxi, Guangdong and Hainan population.

应用生命表技术对荔蝽平腹小蜂Anastatus japonicus Ashmead不同地理种群以柞蚕卵为繁殖寄主的条件下的重要生物学指标和参数进行测定和比较，结果表明，越南种群的主要生殖力指标，包括净生殖力（R0）、内禀增长率、周限增长率、种群倍增时间、单雌产卵量、产卵前期和产卵历期均比广西、广东和海南种群的理想；4种群的雌蜂寿命、羽化率和雌性比率则没有显著差异。
