We compared the survival of larvae of Scepticus griseus (Roelofs) (Coleoptera: Curculionidae) fed on roots of carrot Daucus carota L. subsp. sativus (Hoffm.) Arcang. (Apiaceae), peanut Arachis hypogaea L. (Fabaceae), and seven species of green manure crops in a conical tube experiment to find crops that can be grown in the habitat of this weevil without increasing its numbers. Many weevils survived or emerged when raised on carrot, peanut, African marigold Tagetes erecta L. (Asteraceae), and rye Secale cereale L. (Poaceae), some on mustard Brassica juncea (L.) Czern. (Brassicaceae) and Avena strigosa Schreb. (Poaceae), few on showy crotalaria Crotalaria spectabilis Roth (Fabaceae) and Sudan grass Sorghum × drummondii (Nees ex Steud.) Millsp. et Chase (Poaceae), and none on sorghum Sorghum bicolor (L.) Moench (Poaceae). Thus, showy crotalaria, sorghum, and Sudan grass are not suitable and mustard and A. strigosa are less suitable as hosts for S. griseus , and therefore could be grown as green manure crops in areas where the weevils are found. However, investigation of the effects of the plants on oviposition by weevils is needed to prevent immigration of adults to new habitats.

七种绿肥作物作为蔬菜和大田作物害虫 Scepticus griseus（鞘翅目：仙茅科）幼虫的拮抗剂的评价

我们比较了以胡萝卜 Daucus carota L. subsp. 的根为食的 Scepticus griseus (Roelofs)（鞘翅目： Curculionidae）幼虫的存活情况。sativus (Hoffm.) Arcang。(Apiaceae)、花生 Arachis hypogaea L. (Fabaceae) 和七种绿肥作物在锥形管实验中寻找可以在这种象鼻虫栖息地生长而不增加其数量的作物。许多象鼻虫在用胡萝卜、花生、非洲万寿菊万寿菊（菊科）和黑麦禾本科（禾本科）饲养时存活或出现，一些在芥菜（L.）Czern 上饲养。（十字花科）和Avena strigosa Schreb。（禾本科），少数对艳丽的crotalaria Crotalaria spectabilis Roth（豆科）和苏丹草高粱×drummondii（Nees ex Steud.） Millsp。et Chase（禾本科），高粱上没有 Sorghum bicolor (L.) Moench (Poaceae)。因此，艳丽的crotalaria，高粱和苏丹草不适合，芥菜和 A. strigosa 不太适合作为 S. griseus 的寄主，因此可以在发现象鼻虫的地区作为绿肥作物种植。然而，需要调查植物对象鼻虫产卵的影响，以防止成虫迁移到新的栖息地。
