摘    要:应用种群动态控制的状态空间分析法,通过生命表参数模拟美洲斑潜蝇种群数量动态,通过输入不同的控制措施(施用非嗜食植物次生化合物即马缨丹乙醇提取物、施用机油乳剂和释放美洲斑潜蝇寄生性天敌)对美洲斑潜蝇种群动态控制的作用,研究这些控制措施的组合对美洲斑潜蝇种群动态的控制,模拟结果表明,在美洲斑潜蝇成虫产卵高峰期施用马缨丹乙醇提取物(1g·100ml^-1和机油乳剂(300X),在幼虫高峰期释放寄生蜂(2000头·100m^-2),可以达到控制美洲斑潜蝇种群增长的效果,起到保护菜豆免害的作用。

关 键 词:美洲斑潜蝇  次生化合物  机油乳剂  寄生蜂  种群动态控制

Abstract: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.
Keywords:Liriomyza sativae  Secondary substance  Petroleum spray oil  Parasitoids  Population control
