【摘要】 计算机模拟技术作为一种研究复杂系统的重要手段,已经在有害生物综合治理研究中得到广泛应用。而构建种群动态计算机模拟模型是害虫最优管理中一项主要内容,同时也是研究温室生态系统健康监测与诊断研究工作有待解决的一个课题。温室白粉虱(Trialeurodesvaporariorum Westwood)是我国北方乃至全世界温室作物最重要的害虫之一,已经对瓜类、茄果类、豆类等多种蔬菜生产构成了严重威胁。 本研究针对温室白粉虱最优管理中种群动态模拟问题,以温室主要作物黄瓜为例,研究温室白粉虱在不同黄瓜品种上的种群参数,并就几个北京市主栽黄瓜品种对白粉虱种群增长的影响作简单的评估,构建温室白粉虱在不同黄瓜品种上种群动态模拟模型。模拟结果表明在黄瓜生育期的前期和中期(2月28日-4月15日)温室白粉虱在四个黄瓜品种上的种群数量与实际调查相差不大,但在黄瓜的生育后期(4月17日以后)表现出了差异。本文尝试结合生命表研究技术,获得温室白粉虱在不同黄瓜品种上的种群参数,为建立温室白粉虱在不同黄瓜品种上的种群动态模拟数学模型提供参数,同时也为初步评估不同黄瓜品种对温室白粉虱的种群增长的影响提供了依据。 在以上研究的基础上,最后利用计算机可视化语言形成了软件—温室白粉虱在不同黄瓜品种上种群动态与防治措施计算机模拟系统。这些工作可为制定温室白粉虱的最优控制方案提供参考,同时通过分析温室环境自动监控系统监测得到的环境数据与温室害虫种群动态二者之间的关系,可进一步为温室生态系统健康监测与诊断工作提供有利的工具。

【Abstract】 The Study of the Computer Simulation Model of Whitefly Population Dynamic and its Prevention Measures on difference Cucumber Varieties The technique of computer simulation has been abroadty applied in 1PM research as an important measure to study a complex system. Especially, the construction of a pest population simulation model is a main part of optimum pest management, which is also an urgent problem to research healthy monitoring and diagnosing in the greenhouse ecosystem. Whitefly is one of the most important pests in the north of China even in all part of the world. This pest has been a severe threat to many kind of vegetables. Such as melon, aubergine and legume. This article aimed at optimum pest management in greenhouse, We researched the whitefly population parameter on four cucumber varieties, and simply assessed the influence of the cucumber varieties which are planted abroadly in Beijing, and constructed the whitefly population dynamic simulating model. The simulating res!lts showed that there was little difference between the simulating number and the practical investigating in the most part of the cucumber bearing period, but there was an evident diversity in the back period. We attempt to use life table technique to acquire the whitefly population parameter, so that this means can provide parameter for the simulating mathematical model, it also is easy to assess the influence of the four cucumber varieties, on caomi, sandongmici, lishi and tiancuilu. According to the results, we designed the software ?the simulation system of whitefly population dynamic and management measure. These work provided reference for finding an optimum management scheme, also supply an avail implement for analyzing the relation between environmental data and whitefly population dynamic, it can do good to healthy monitoring and diagnosing in greenhouse ecosystem health.
