The introduction of flowering plants into orchards can increase functional biodiversity in pome fruit cultivation. Plants provide nectar, pollen and prey resources supporting pollinators and natural enemies. However, pests may also benefit from floral diets and a careful selection of plants is necessary to reduce any risk of pest proliferation. The codling moth Cydia pomonella is a major pest in apple growing worldwide and adults are known to consume sugars. The impact of floral diets (parsnip, wild carrot, coriander, red clover) on longevity, fecundity and fertility of adult codling moth was examined under laboratory conditions. In general, male moths lived longer than females, regardless of dietary treatments. Moths survived longest when supplied with parsnip flowers as a floral diet. Contrary to carrot, coriander resulted in higher longevity of adult C. pomonella compared to moths provided with red clover as a negative control. Adult nutrition on floral diets did not affect fecundity substantially. As expected, the majority of eggs were laid within the first week. Prolongation of moths’ lifespan by floral diets did not significantly increase the total number of eggs laid in contrast to a diet with 25% sucrose solution. According to these results, the risk of inadvertently promoting codling moth when growing selected flowering plants in the orchard will be rather low, because the fitness of the moths and especially the reproduction of the females will not be substantially enhanced.

花卉资源是否会影响成虫 Cydia pomonella (Linnaeus 1758)（鳞翅目：Tortricidae）的适应性？


将开花植物引入果园可以增加仁果种植的功能性生物多样性。植物提供花蜜、花粉和猎物资源，支持传粉媒介和天敌。然而，害虫也可能受益于花卉饮食，因此必须仔细选择植物以减少害虫繁殖的风险。苹果蠹蛾苹果蠹蛾是世界范围内苹果种植的主要害虫，众所周知，成虫会消耗糖分。在实验室条件下研究了花卉饮食（防风草、野胡萝卜、香菜、红三叶草）对成年苹果蠹蛾的寿命、繁殖力和繁殖力的影响。一般来说，无论饮食治疗如何，雄性飞蛾的寿命都比雌性长。当以防风草花作为花卉食物时，飞蛾存活时间最长。与胡萝卜相反，香菜可以延长成年人的寿命苹果蠹与提供红三叶草作为阴性对照的飞蛾相比。花卉饮食中的成虫营养并不会显着影响繁殖力。正如预期的那样，大部分鸡蛋是在第一周内产下的。与含有 25% 蔗糖溶液的饮食相比，花卉饮食延长了飞蛾的寿命，但并没有显着增加产卵总数。根据这些结果，在果园中种植选定的开花植物时，无意中促进苹果蠹蛾的风险相当低，因为苹果蠹蛾的适应性，特别是雌性的繁殖不会得到实质性的增强。
