肉桂突细蛾 Gibbovalva quadrifasciata(Stainton)是樟科植物叶部重要害虫 ,在漳州华安 1年发生 8代 ,世代重叠 ,以蛹于 1 2月中、下旬在地表落叶、杂草和树皮缝中越冬。翌年 2月底、3月初成虫羽化、交配、产卵。幼虫孵化后潜入叶表皮取食叶肉组织造成叶枯黄凋落。虫害在林分的上部发生重于中、下部 ,林缘重于林内。用 5 0 %久效磷乳油、5 0 %甲胺磷乳油、40 %氧化乐果乳油常规喷雾均有良好防治效果 ,用做树干注射可明显降低害虫发生率。幼虫期主要天敌有姬小蜂科 2种和扁股小蜂科 1种 ,蛹期有姬小蜂科 2种
Gibbonvalva quadrifasciata (Stainton) is an important insect in leaves of Lauraceae. Occurred 8 generations a year in Hua’an, Zhangzhou.

Pests occur in the upper part of the forest in the middle and lower part of the edge of the forest in the forest. With 50% monocrotophos, 50% methamidophos, 40% omethoate conventional spray has good control effect, used as a trunk injection can significantly reduce the incidence of pests. The main natural enemies of larvae have two kinds of small diptera and two kinds of flat beewort 1 species, pupal stage have two kinds of small insects Division 2
