摘要
拟隐脉叶蝉原分布于东南亚及我国南方,近年传入美国并在夏威夷等地爆发
    成灾。为了从拟隐脉叶蝉的原产地寻找有效天敌,以便在传入地开展生物防治,
    我们近年在福建省福州市对淡色拟隐脉叶蝉和叉线拟隐脉叶蝉的种群动态、生物
    学特性及其天敌进行了初步调查。结果获知:淡色拟隐脉叶蝉和叉线拟隐脉叶蝉
    年可发生3~4代,若虫5龄,世代重叠,没有明显的越冬现象。在福州,淡色拟
    隐脉叶蝉的寄主有番石榴、大豆、花生、甘薯和扁豆,罩养条件下,其也能在相
    思树上取食产卵,夏秋时节,甘薯上取食为害的数量多于其它寄主;叉线拟隐脉
    叶蝉的寄主包括相思树、番石榴、甘薯、花生和扁豆。8~10月份,淡色拟隐脉
    叶蝉卵期平均为19.2天,叉线拟隐脉叶蝉平均为21.8天。它们的天敌已知有14
    种,其中寄生性天敌11种,捕食性天敌3种。在10种卵寄生蜂中,毛翅缨小蜂
    Chaetomymar sp.为优势种,占寄生蜂总数的57.6%。自然条件下,淡色拟隐脉叶
    蝉卵寄生率平均为50.6%,9月份最高时可达91.4%。不同植物、不同生境条件
    下寄生蜂种类、数量及寄生率都有差异。
Sophonia leaihoppers originally distributed in Southeast Asia and southern
    
     China. They were inadvertently introduced to Hawaii in recent years and have caused
    
     severe damage to many agricultural crops as well as endemic plants. In order to find
    
     out the effective natural enemies in their native regions for biological control, the
    
     exploration and investigation of their natural enemies were conducted in Fuzhou from
    
     1998. Studies on the population dynamics of Sophonia pal/ida (Melichar) on guava and
    
     Sophoniafurcilinea (kuoh et kuoh) on Acacia confusa in Fuzhou indicated that the 2
    
     kinds of Sophonia leafhoppers occurred 3? generations per year. They keep
    
     developing without distinct overwintering and have overlapping generations. Nymphs
    
     occur 5 instars. In Fuzhou, the plant hosts of S. pal/ida included guava, soybean,
    
     peanut, sweet potato and hyacinth bean. When caged on the shoots of Acacia confusa,
    
     S. pallida could also feed and oviposit on them. In guava orchard, S. pallida would like
    
     to feed on sweet potato more than on other plant hosts in summer and fall. The plant
    
     hosts of S. furcilinea included Acacia confusa , guava, peanut, sweet potato and
    
     hyacinth bean. During August to October, the egg's mean development duration of S.
    
     pa//ida and S. furcilinea was 19.2 and 21 .8 days respectively. Three kinds of predators
    
     and eleven kinds of parasites have been found in Fuzhou. Among the 10 kinds of egg-
    
     parasitoids, Chaetomytnar sp. (Mymaridae) is the most abundant species which
    
     occupies 57.6% in the total parasites population. The egg percent parasitism in natural
    
     orchards is 50.6% in average, with a peak parasitism in September reaching up to
    
     91 .4%. The parasitoid guild and percent parasitism varied depending on plant and on
    
     habitat.
