The potato tuber moth (PTM), Phthorimaea operculella (Zeller 1873) (Lepidoptera: Gelechiidae), is a destructive pest of stored potatoes and potato crop. Biopesticides are certain types of pesticides derived from animals, plants, and bacteria. Botanicals are especially efficient in the form of antifeedant, repellent, protectants, and growth-disrupting hormones. They are also sources of secondary metabolites that are safer than synthetic insecticides. Present research was conducted to evaluate some botanical extracts as natural local alternatives against PTM under storage conditions. Twelve different 80% ethanolic plant extracts were tested on PTM during storage condition (30 ± 2°C and 70 ± 5% RH) at a light regime of the day 10-h light and 14-h dark. Biological parameters of the pest, evidence of the potato tubers damage, and continuation of protection to the tubers were recorded. Extracts of mint, zygophyllum, coriander, arnoglosse, harmel, and solanum indicated a total inhibition of egg deposition at 2.5% concentration; also, they provided high protections to the potato tubers from the PTM infestation for about 3 months and without observations’ effect on tubers germination. Senna, colocynth, and basil reduced the number of deposited egg/female. Jasmine, geranium, and chamomile recorded a low potential on egg deposition. Basil showed the highest potency in decreasing development of larvae that hatched from eggs, therefore, reduced the number of next adult offspring (F1) and followed by jasmine and geranium. Variable levels of extracts’ protection can be arranged according to their damage evidence as follows: basil > colocynth > jasmine > geranium > senna > chamomile.

在储存条件下，针对马铃薯块茎蛾Pthorimaea operculella（Zeller 1873）（鳞翅目：Gelechiidae）的植物提取物。

马铃薯块茎蛾（PTM），Phthorimaea operculella（Zeller 1873）（鳞翅目：Gelechiidae），是储存的马铃薯和马铃薯作物的破坏性害虫。生物杀虫剂是源自动物，植物和细菌的某些类型的杀虫剂。植物药以拒食剂，驱虫剂，保护剂和破坏生长激素的形式特别有效。它们也是次生代谢产物的来源，其比合成杀虫剂更安全。目前的研究旨在评估一些植物提取物在储存条件下作为天然抗PTM的替代品。在储存条件下（30±2°C和70±5％RH），在光照10h和黑暗14h的光照条件下，在PTM上测试了十二种不同的80％乙醇植物提取物。害虫的生物学参数，马铃薯块茎受损的证据，并记录了对块茎的持续保护。薄荷，合子，香菜，生铁片，harmel和茄属植物的提取物在2.5％的浓度下可完全抑制卵的沉积。而且，它们为马铃薯块茎提供了3个月的PTM侵害的高度保护，并且没有观察到对块茎发芽的影响。番泻叶，芋和罗勒减少了产卵/雌性的数量。茉莉，天竺葵和洋甘菊的卵沉积潜力低。罗勒对减少从卵中孵出的幼虫的发育表现出最高的效力，因此减少了下一个成年后代（F1）的数量，其次是茉莉和天竺葵。提取物的保护程度可根据其破坏证据而定，如下所示：罗勒>芋头>茉莉>天竺葵>
