| 摘 要： | 木兰突细蛾Gibbovalvaurbana(Meyrick)为木兰科植物叶部的重要害虫之一。在广州年发生 8代 ,世代重叠 ,以蛹越冬。翌年 2月下旬、3月上旬成虫羽化、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。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有良好防治效果。幼虫期、蛹期主要天敌有姬小蜂科 2种。蛹期还有一种病菌感染。

| Abstract: | Gibbovalva urbana (Meyrick)is one of important leaf pests on Magnolia plants.It has 8 generations a year in Guangzhou and the generations overlap.It overwinters as pupae.The adult emerges,mates and lays eggs from the end of February to the beginning of March in the next year.The larvae feed on mesophyll tissues and make leaves yellow and defoliated.Conventional spraying of 50% Monocrotophos,50% Methamidophos or 40% Omethoate emulsion oil can effectively control the pest. |
