摘要
本文报道了福建省漳浦地区马尾松毛虫(Dendrolimus punctatus)的生物学、生态学特征及种群动态行为,并建立了种群动态的模拟模型。通过实验研究,考察了马尾松毛虫各阶段的存活率、成虫生殖力、世代分化情况,以及松树受害程度对松毛虫存活率的影响。在此基础上,建立了松树失叶率与松毛虫存活率之间的关系模型以及松毛虫种群动态过程的计算机模拟模型。应用这些模型进行了马尾松毛虫种群动态的预测,并模拟了马尾松毛虫暴发的过程。
Some aspects of the population dynamics of masson pine Caterpillar (Dendrolimus punc-tatus Walker) and their simulation models are investigated. Results of field experimental studies concerning several important processes in the natural dynamics of the insect pest are pre-sented. These include the survival rates of various stages in the life cycle, the fertility of the moth and the interaction between the pest and the host tree. Based on experimental data, a mathematical model describing the effect on the degree of leaf damage of pine tree on the survival rates of the pest is proposed. Computer simulation models are developed to predict po-pulation dynamics and to demonstrate the outbreak cycle of the pest.
