Abstract While lupin has undergone extensive research to ascertain its suitability for growth as forage or grain legume crop, the present trend is for research to be centered on its applicability in the seed protein and oil industry. Study of the literature showed that no intensive study of the lupin insect fauna had been carried out in Bulgaria. The purpose of this study was to identify the insect assemblages associated with Lupinus albus and L. luteus, as well as the insect preference for them. Thrips sampling was made by the tapping-method, aphids were directly counted on the plants and the composition and population density of other species were recorded by sweepings. Insect fauna was studied for the first time in Bulgaria. The fauna was represented on L. albus by 64 species, belonging to eight orders, 28 families and 57 genera, including 23 beetles, 25 hemipteras, five thrips, three butterflies, three bees, one leaf aphid, two grasshoppers, one leafminer and one green lacewing. L. luteus had similar species composition but was less preferred by insects. The use of lupin cultivars with shorter and intense reproductive periods, with a lower content of crude protein and phosphorus, would give an environmentally friendly protection against insect pests, which would be suitable for an organic production system.

昆虫组合及其对 Lupinus albus 和 L. luteus 的偏好

摘要 虽然羽扇豆已经进行了广泛的研究以确定其作为牧草或谷物豆类作物的生长适宜性，但目前的研究趋势是将研究集中在其在种子蛋白和油工业中的适用性上。文献研究表明，保加利亚没有对羽扇豆昆虫群进行深入研究。本研究的目的是确定与 Lupinus albus 和 L. luteus 相关的昆虫组合，以及昆虫对它们的偏好。蓟马采样采用敲击法，蚜虫直接在植株上计数，其他物种的组成和种群密度通过扫查记录。保加利亚首次研究了昆虫群。动物群在 L. albus 上有 64 种，属于 8 目、28 科和 57 属，包括23只甲虫、25只半翅目、5只蓟马、3只蝴蝶、3只蜜蜂、1只叶蚜、2只蚱蜢、1只潜叶虫和1只绿草蛉。L. luteus 具有相似的物种组成，但不太受昆虫的青睐。使用繁殖期较短、强度较高、粗蛋白和磷含量较低的羽扇豆栽培品种，可提供对害虫的环保保护，适合有机生产系统。
