The carnation tortrix moth, Cacoecimorpha pronubana (Hübner, [1799]) (Lepidoptera: Tortricidae), is one of the most economically important insect species affecting the horticultural industry in the UK. The larvae consume foliage, flowers or fruits, and/or rolls leaves together with silken threads, negatively affecting the growth and/or aesthetics of the crop. In order to understand the polyphagous behaviour of this species within an ornamental crop habitat, we hypothesized that different host plant species affect its life history traits differently. This study investigated the effects of the host plant species on larval and pupal durations and sizes, and fecundity (the number of eggs and the number and size of egg clutches). At 20°C, 60% RH and a 16L:8D photoperiod larvae developed 10, 14, 20 and 36 days faster when reared on Christmas berry, Photinia (Rosaceae), than on cherry laurel, Prunus laurocerasus (Rosaceae), New Zealand broadleaf, Griselinia littoralis (Griseliniaceae), Mexican orange, Choisya ternata (Rutaceae), and firethorn, Pyracantha angustifolia (Rosaceae), respectively. Female pupae were 23.8 mg heavier than male pupae, and pupal weight was significantly correlated with the duration of larval development. The lowest and the highest mean numbers of eggs were produced by females reared on Pyracantha (41) and Photinia (202), respectively. Clutch size differed significantly among moths reared on different host plants, although the total number of eggs did not differ. This study showed that different ornamental host plants affect the development of C. pronubana differently. Improved understanding of the influence of host plant on the moth's life history parameters measured here will help in determining the economic impact that this species may have within the ornamental plant production environment, and may be used in developing more accurate crop protection methodologies within integrated pest management of this insect.

康乃馨 tortrix 蛾，Cacoecimorpha pronubana(Hübner, [1799]) (鳞翅目: Tortricidae)，是影响英国园艺业的最重要的经济昆虫物种之一。幼虫吃树叶、花朵或果实，和/或将叶子与丝线一起卷起，对作物的生长和/或美观产生负面影响。为了了解该物种在观赏作物栖息地中的多食行为，我们假设不同的寄主植物物种对其生活史特征的影响不同。这项研究调查了寄主植物物种对幼虫和蛹的持续时间和大小以及繁殖力（卵的数量和卵窝的数量和大小）的影响。在 20°C、60% RH 和 16L:8D 光周期的条件下，在圣诞浆果石楠中饲养的幼虫发育速度快 10、14、20 和 36 天（蔷薇科），比对樱桃月桂、月桂属（蔷薇科）、新西兰阔叶、西海参（ Griseliniaceae）、墨西哥橙、半夏（芸香科）和火棘、火棘（蔷薇科）分别。雌蛹比雄蛹重23.8 mg，蛹重与幼虫发育时间显着相关。以火棘(41) 和石楠 ( Photinia )饲养的雌性产卵量最低和最高（202），分别。尽管卵的总数没有差异，但在不同寄主植物上饲养的飞蛾的离合器大小差异很大。本研究表明，不同的观赏寄主植物对红花的发育影响不同。更好地了解寄主植物对此处测量的飞蛾生活史参数的影响，将有助于确定该物种在观赏植物生产环境中可能产生的经济影响，并可用于在害虫综合管理中开发更准确的作物保护方法这种昆虫。
