为了防止害虫造成储藏产品中的谷物损失，需要采用替代杀虫剂喷洒的虫害控制技术。为此目的使用天然材料可能是有益的，在这种情况下，我们筛选了21种植物，发现一种山茶科植物抑制鳞翅目昆虫幼虫的生长。因此，在纯化和分析来自I. Virginicaleaves、allitol和d-阿洛酮糖（阿洛酮糖）被鉴定为针对地中海面粉蛾Ephestia kuehnielaZeller（鳞翅目：螟蛾科）幼虫的生长抑制剂。大蒜中大蒜素和d-阿洛酮糖的含量均高于对照。估计Virginicaleaves分别为14.4和4.17 mg/g fr. wt，其半最大有效浓度（EC 50）值分别为15.7和30.3 mg/g饲料。因此，I. virginicaleaves主要归因于大蒜糖醇的存在。然而，这两种化合物都可以用于杀虫试剂，特别是，由于d-阿洛酮糖的安全性已经得到证实，因此可以使这种害虫管理试剂直接与储存产品食品混合。
To prevent the loss of grains in stored products due to pests, an alternative pest control technique to insecticide spraying is required. The use of natural materials for this purpose can be beneficial, and in this context, we screened 21 plants and found that anIteaceaeplant inhibited the growth of lepidopteran insect larvae. Accordingly, following purification and analysis of the plant extract fromI. virginicaleaves, allitol andd-allulose (psicose) were identified as growth inhibitors against larvae of the Mediterranean flour moth,Ephestia kuehniellaZeller (Lepidoptera: Pyralidae). The contents of allitol andd-allulose inI. virginicaleaves were estimated to be 14.4 and 4.17 mg/g fr. wt, respectively, and their half-maximal effective concentration (EC50) values were 15.7 and 30.3 mg/g diet, respectively. Therefore, the growth inhibition activity inI. virginicaleaves was mainly attributed to the presence of allitol. However, both compounds may be used in insecticidal reagents, and in particular, since the safety ofd-allulose has already been confirmed, it could allow this pest management reagent to be directly mixed with stored-product foods.
