摘要
谷物中有多种储粮害虫,米象作为谷物中常见的储粮害虫之一,会对谷物和加工后的产品造成严重的危害,导致其品质下降。因此对米象害虫的预防和治理是谷物储藏期间的关键问题。以谷物中的小米为研究对象,在考虑温度和湿度情况下,对米象群落的发展趋势进行仿真预测研究。根据小米米象群落发展的特征和规律,定义了小米米象群落在不同温湿度情景下的停止生长、生长但不繁殖以及生长繁殖3种行为和行为规则,把米象群落发展区域分割为若干个二维和三维的元胞空间结构,把元胞空间结构中元胞状态为“米象成虫”和“米象非成虫”的网格看成是一种智能体。构建了米象群落发展趋势模型,对其发展趋势进行仿真研究,该模型能够较好地描述小米米象群落发展趋势,针对3种不同温湿度环境下的发展趋势与仿真对比分析,仿真结果与实际结果吻合较好,趋势一致,所构建的仿真模型具有较高的准确性,可以为抑制米象群落发展,保障粮食储藏安全提供一种预测和模拟方法。
Multiple grain storage pests exist in grains,and Sitophilus oryzae,as one of the common grain storage pests in grains,can cause serious harm to grains and processed products,leading to a decline in quality.Therefore,prevention and control of Sitophilus oryzae are crucial issues during grain storage.Taking millet in grains as the research object,the development trend of Sitophilus oryzae communities was simulated and predicted considering temperature and humidity conditions.Based on the characteristics and rules of millet Sitophilus oryzae population development,the three behaviors and corresponding rules of growth cessation,growth without reproduction,and growth with reproduction in millet Sitophilus oryzae population under different temperature and humidity scenarios were defined.The development area of the Sitophilus oryzae population was divided into multiple two-dimensional and three-dimensional cellular spatial structures.The grids with cellular states of“Sitophilus oryzae adult”and“Sitophilus oryzae non-adult”were regarded as intelligent agents.A model for the development trend of Sitophilus oryzae communities was constructed and simulated.The model can better describe the development trend of small Sitophilus oryzae communities,and the development trend under three different temperature and humidity environments was compared and analyzed through simulation.The simulation results are in good agreement with the actual results,and the trend is consistent.The simulation model constructed has high accuracy and can be used to suppress the deve-lopment of Sitophilus oryzae communities,and provide a prediction and simulation method to ensure the security of grain storage.
