Abstract To study the underground pest species and their occurrence regulation，field surveys were carried out from 2010 to 2013，by black light lamp trap method at alpine redish（Raphanus sativus） production base with 1 800 m altitude in Huoshaoping Town Changyang County of Hubei Province. The results showed that there were 11 species of alpine radish underground pests belonged to 4 orders and 7 families. Among them Agrotis ypsilon，Phyllotreta striolata and Delia platrua were dominant insect pests，which could cause serious damage. A. ypsilon had great population density in mid，late June，and mid July. P. striolata had great population densitiy in August.D. platura was found in radish fields with great population density in May. This paper suggests taking A. ypsilon，P.striolata and D. platura as main targets for developing underground pest forecasting and management strategy.
