| 摘 要： | 茶须野螟(Nosophora sem itritalis)主要危害木荷(Schima superbaGardn.et Champ.)当年生的嫩芽、嫩叶与嫩梢,亦危害老叶。该虫在福建尤溪1 a发生3代,以1~2龄幼虫在缀叶中越冬。第1、2、3代幼虫危害盛期分别为5月下旬、8月上旬和翌年4月上、中旬,成虫羽化盛期分别为7月中旬初、9月中旬初和翌年5月上旬。在幼虫期用25%灭幼脲Ⅲ号2 000倍液或2.5%敌杀死1 500倍液喷雾防治;在成虫羽化期燃放“敌马”烟剂,防治效果均达90%以上。成虫羽化盛期还可用黑光灯诱杀。

| Abstract: | Nosophora semitritalis bored shoots,young leaves,young shoot of Schima superba,also bored hard mulberry leaf.It has 3 generations annually in Youxi County of Fujian and overwinters as 1~2-year-old larvae on deciduous leaves.Major onset of damage of 1~3 generations is the last ten-day of May,the first ten days of August,the first and middle ten days of April respectively.The emergence major onset of adult is the onset of the middle ten days of July,the onset of the middle ten days of September and the first ten days of May.Control by spraying by using 25% chlorbenzuron with concentration of 2 000 and 2.5% Drics with concentration of 1 500 under larval stage,touching off "Dima" smoke agent in emergence period of adult,the control efficiency reached above 90%.Taking black-light lamp for trapping adult in major onset of emergence could be used. |
