| 摘 要： | 木兰突细蛾Gibbovalva urbana(Meyrick)]是木兰科植物叶部的害虫,在福建省南平地区一年发生6代,以蛹越冬。翌年2月上、中旬正值木兰科植物盛花期,开始羽化。成虫上树补充营养、交配产卵。卵散生在嫩叶表面,经2～4天孵化为幼虫。幼虫期18～19天,蛹期8～20天,越冬蛹36～49天,成虫寿命2～5天。试验表明:50％甲胺磷乳剂、50％辛硫磷乳剂、40％氧化乐果乳剂、40％水胺硫磷乳剂、2.5％溴氰菊脂乳剂,以1000～3000倍液防治中龄幼虫,均有良好效果。该虫主要天敌有多胚跳小蜂(Ageniaspis sp.)绒茧蜂(Apanteles sp.)姬小蜂科(Eulophidae)以及陆马蜂Polistes(Megapostes)rothneyi grahami van der vecht]广腹螳螂(Hierodula patellifera serville.)等。

| Abstract: | Gibbovalva urbana feeds on the leaves of the trees of Magnoliaceae. It has six generations per year and overwinters as pupae in Nanping Prefectu-ral area. Between early February and middle February the overwintering pupae emerge as adult, which flies to the trees to take food and mate there.The eggs are laid on the surface of the tender leaves, which, in 2-4 days, bagin to hatch. The larvae stage last about 18-19 days and the pupal stage lasts about 8-20 days (the overwintering pupal stage lasts 36-49days), and the adult's life-span is 2-5 days. Our experiment showed that the following control measures are effective respectively: spraying of 50% methamidophos, 50% phox-im emulsion, 40% Omethoate emulsion, 40% Isocarbophos emulsion and 2.5% Deltamethrin emulsion in concentration of 1:1000-3000.
The important natural enemies of Gibbobalva urbana are Ageniaspis sp., Apanteles sp. , Eulophidae, Polistes (Megapostes) rothmeyi grahami Van der Vecht, Hierodula patellifera serville and the like. |
