Biology, Pest Status and Management of Armyworm Spodoptera litura and Cutworm Agrotis ipsilon (Noctuidae: Lepidoptera) on Sugar Beet

Abstract

Sugar beet (Beta vulgaris L.: Chenopodiaceae), a temperate, biennial crop, is infested by more than 500 insects and non-insect pests throughout the world. Among all the defoliating pests, beet armyworm (Spodoptera litura) and cut worm (Agrotis ipsilon) are of major concern in India. In this chapter, the spectrum of various pests, pest status, and the economic losses caused by them are discussed. The biology and distribution of armyworm and cutworm, which are the major pests of the sugar beet crop in the country, are illustrated with larval, pupal, and adult periods. Suitable integrated management practices including cultural, biological, and chemical interventions and future prospects are also discussed. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
