PRACTICAL PROBLEMS FOR BIOLOGICAL CONTROL OF SPIDER MITES BY THE USE OF PHYTOSEIIDS.

为了给实际农业生产中的生物防治提供参考，本文建立了植绥螨捕食者与叶螨捕食者相互作用的计算机模拟模型，该模型能较好地模拟捕食者与被捕食者之间的相互作用格局。猎物相互作用。在多个地点的多种作物和蔬菜中收集了模拟生物防治所需的温度数据在日本，这些数据被输入计算机作为文件，用于应用植绥螨在温室栽培植物上的螨类害虫生物防治中的有效性预期。该模拟模型可以评价植绥螨捕食者在一定环境下作为生物防治剂的效率，因此，模拟的计算机程序可以作为一个简单的控制工具，手册.

A simulation model of the interaction between phytoseiid predators and tetranychid prey by the use of a personal computer was developed in order to provide a manual of biological control in practical agricultural fields.The simulation model developed could simulate well an observed pattern of predactor-prey interaction.Temperature data which should be necessary for the simulation of biological control was collected in several crops and vegetables in several locations in Japan.These were inputed in a computer as files for applying expectation of the availability of phytoseiids in biological control of mite pests on greenhouse cultivating plants.By the use of the temperature data, the simulation model could evaluate the efficiency of the phytoseiid predactor at certain environments as an agent of biological control.Thus the computer program for the simulation may become useful for such a control attempt as a simple manual.
