玫瑰三节叶蜂是月季的重要害虫之一,在福建南平,室内饲养一年发生8代,世代重叠,以蛹于土中茧内越冬。卵多个呈两排,整齐地产于嫩稍的枝条内,达髓部深处。幼虫取食嫩叶,可吃净嫩梢,甚至整个枝条,影响月季的正常生长,降低了月季的观赏价值。幼虫老熟时下地入土结茧。两性或孤雌生殖。幼虫6龄,少数为4龄或5龄。 在室内对3—6龄幼虫喷洒90％的敌百虫晶体10,000倍液或50,000倍液;80％敌敌畏乳油30,000倍液或50,000倍液;40％乐果乳油10,000倍液;50％的辛硫磷乳油10,000倍液或20,000倍液均有良好防治效果。
Rose three leaf bee is one of the important pests of rose, in Nanping, Fujian, indoor breeding occurred eight generations a year, generations overlap, with pupa in the soil cocoon winter. Multiple eggs in two rows, neatly produced in tender branches, reaching the depths of the medulla. Larvae feeding young leaves, eat clean shoots, or even the entire branches, affecting the normal growth of the rose, reducing the ornamental value of the rose. When the larvae mature into the soil cocoon. Bisexual or Parthenogenesis. 6 larvae, a few for the 4 or 5 age. 3-6 instar larvae were sprayed indoor with 10,000 times of 90% trichlorfon crystals or 50,000 times of liquid; 30,000 times of 80% dichlorvos EC or 50,000 times of liquid; 10,000 times of 40% dimethoate EC; 50% Phospholipid 10,000 times or 20,000 times liquid have good control effect.
