摘要
应用性诱剂对湖北高山蔬菜小菜蛾的发生动态进行了监测。结果表明,2002年小菜蛾在第一茬甘蓝上有两个发生高峰,诱蛾量分别为11.7±2.4头·盆-1和9.2±1.0头·盆-1,在第二茬甘蓝上有3个发生高峰,诱蛾量分别为70.9±8.1头·盆-1、16.1±2.7头·盆-1和11.1±1.9头·盆-1;2003年小菜蛾在第一茬甘蓝上有3个发生小高峰,诱蛾量分别为4.7±1.7头·盆-1,6.2±1.9头·盆-1和6.3±2.0头·盆-1,在第二茬甘蓝上有3个发生高峰,诱蛾量分别为62.5±27.4头·盆-1,88.7±25.1头·盆-1和12.6±3.4头·盆-1。性诱剂与频振式杀虫灯相比,性诱剂监测小菜蛾更为灵敏,诱捕效果更好。
Monitoring of the diamondback moth, Plutella xylostella with sex pheromone on high mountain in Hubei were applied in 2002 and 2003. The results showed that in 2002, the population of the DBM had three peaks in the first crop of cabbage field and two peaks in the second crop of the cabbage field. In 2003 year the happen of the DBM both had three peaks in the first crop and the second crop of the cabbage fields,respeetively. The population in the second crop was more than that in the first crop in the two year. The sex pheromone was superior to pest-killing lamp in monitoring the population of DBM.
