The Greenhouse Whitefly Population Dynamics And Control Measures Simulation System Development In The Different Varieties Of Cucumbers

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.
