This study was performed to analyze the sugar contents from six kinds of plant and investigate their effect on the life span of ggot-mae-mi, Lycorma delicatula. Part of plants were methanol extracted from host plants such as Ailanthus altissima, Vitis vinifera and non-host plants such as Malus pumila, Pyrus calleryana, Hibiscus syriacus, and Pinus densiflora, and concentrated the water layer and then analyzed the sugar contents using HPLC. Ailanthus altissima existed high in sugar contents and followed by Fructose>Glucose, Vitis vinifera was analyzed by an order of Glucose>Fructose>Maltose>Sucrose>Rhamnose; Malus pumila was as Glucose>Fructose; Pyrus calleryana was as Glucose>Unknown>Fructose; Hibiscus syriacus was as Sucrose>Glucose; Pinus densiflora was as Fructose>Glucose>Sucrose. A parafilm bioassay was used to investigate the longevity of L. delicatula nymphs to the sugar contents. Nymphs of L. delicatula was lived as long as 13.1 days in 5% Sucrose solution, but lived as short as 6.0 days in 5% Glucose solution. When provided with only water, L. delicatula lived for 5.4 days. Life span to the each sugar contents were longer lived in an order of Sucrose>Fructose>Rhamnose>Maltose>Glucose. As investigated the life span of L. delicatula nymph according to the combination of sugar contents founded in original plants were lived longer in 5% sugar combination solution of Ailanthus altissima. Analyzed original sugar contents from Malus pumila, Pyrus calleryana, L. delicatula was lived as 7.8, and 7.1 days, respectively, comparing to the Hibiscus syriacus, and Pinus densiflora lived as 6.0, and 4.7 days, respectively. This result were judged that sugar contents affected on choosing the host plants.
