【摘要】 在山西省调查结果,美洲斑潜蝇的寄主有29种栽培植物,11种野生植物,它们分属16个科,其中以葫芦科、茄科和豆科的种类居多。应用选择系数法和适合性指数法定量测定了16种常见寄主对美洲斑潜蝇的适合度,建立了选择强度与适合度估测模型。根据适合度将美洲斑潜蝇的寄主植物划分为3个类型,即适宜寄主、较适宜寄主和次要寄主。在上述研究的基础上,测定了该蝇在不同寄主上的虫道面积和蛹的重量,明确了不同寄主植物对害虫发育的影响,为美洲斑潜蝇的防治决策提供了理论依据。更多还原

【Abstract】 The host plant species of vegetable leafminer Liriomyza satiae Blanchard in Shanxi Province were investigated There were 29 cultivated and 11 wild plant species under 16 families determined as its host plants and Cucurbitaceae,Solanaceae and Leguminosae were dominant The goodness of fit of 16 common host plants to the leafminer were quantitatively tested and the model for estimating their selection intensity and fitness level was established According to the fitness indexes,the host plants of L sativae have been divided into three categories by the hierachical clustering analysis:the most suitable,suitable and secondary Through the determinations of the mine area and pupal weight for L sativae on host plants,the effects of different host plants on the development of L sativae were preliminarily defined The results provided a theoretical basis for the control decision of this leafminer更多还原
