A state-space population model was used to evaluate the effect of plant secondary substances and ecological measures on the population dynamics of the vegetable leafminer, Liriomyza sativae. In the vegetable field, by spraying alcohol extracts of Lantana camara (1 g.100 ml-1), or spraying the petroleum spray oil (300 x), or releasing the parasitoids, the indices of population control(IIPC) of L. sativae compared with control were 0.136, 0.222 and 0.292, respectively, but the index of population trend of vegetable leafminer in control was as high as 11.15, the population of vegetable leafminer still increased by control each one of the methods. Based on the state space analysis, the controlling effects of the alcohol extracts combining with other methods on vegetable leafminer were stimulated, which showed that the alcohol extracts from Lantana camara (1 g.100 ml-1) plus horticultural spray oils(300 x) used once at the period of adult summit, and the parasitoids released 1000 to 2000 per 100 m2 gave the index of population of vegetable leafminer below 1, means that vegetable leafminer would be controlled sustainably.
利用状态空间种群模型评估植物次生代谢物质和生态措施对蔬菜潜叶蝇（Liriomyza sativae）种群动态的影响。在蔬菜田中，通过喷施马缨丹（Lantana camara）酒精提取物（1 g·100 ml-1）、喷施矿物油（300倍）或释放寄生蜂，与对照相比，蔬菜潜叶蝇的种群控制指数（IIPC）分别为0.136、0.222和0.292，但对照中蔬菜潜叶蝇的种群趋势指数高达11.15，采用上述任何一种方法后蔬菜潜叶蝇种群仍呈增长态势。基于状态空间分析，模拟了马缨丹酒精提取物与其他方法联用对蔬菜潜叶蝇的控制效果，结果表明，在成虫高峰期喷施1次马缨丹酒精提取物（1 g·100 ml-1）加矿物油（300倍），每100 m2释放1000~2000头寄生蜂，蔬菜潜叶蝇种群数量可控制在1以下，即蔬菜潜叶蝇可得到持续控制。
