Life tables are an important tool to forecast the performance of biological control agents used in pest management programs, and they are often assessed in terms of population growth. In the present study, the suitability of the aphids Scopoli and (Sulzer) for the ladybird predator Mulsant was assessed for the first time. For this, we evaluated and compared the life history traits of immature individuals and adults of the predator fed single-aphid diets and the consequences of the single-aphid diets for the demographic parameters. that were fed were significantly more fecund and presented a shorter immature development time than those fed . The predators fed had a significantly higher net reproductive rate, an intrinsic and finite rate of increase, while their doubling time was significantly lower than that of those fed . The aphid species used in this study are new additions to the essential prey list of the ladybird, with the predator presenting a better biological performance than that found on the previously known essential prey species.
生命表是预测害虫管理项目中所使用的生物防治剂性能的重要工具，并且它们通常根据种群增长情况进行评估。在本研究中，首次评估了蚜属蚜虫和（苏尔泽）蚜虫对瓢虫捕食者穆尔桑特的适宜性。为此，我们评估并比较了以单头蚜虫为食的捕食者未成熟个体和成虫的生活史特征，以及单头蚜虫饮食对种群统计学参数的影响。取食的捕食者比取食的捕食者繁殖力显著更高，未成熟发育时间更短。取食的捕食者净繁殖率、内禀增长率和有限增长率显著更高，而其加倍时间显著低于取食的捕食者。本研究中使用的蚜虫种类是瓢虫必需猎物名单中的新成员，该捕食者在生物学性能上比之前已知的必需猎物种类表现更好。
