桃小食心虫 (Carposina niponensis) 在中国北方是为害苹果树的重要食心虫。该虫的性信息素已广泛用于测报和诱捕防治。本文报道用交配干扰法防治桃小食心虫试验结果。 本试验采用日本信越化学公司提供的桃小性信息素塑料管剂型,于1989年在北京市南口农场三分场进行。选两块苹果地作为试验区。交配干扰区苹果树为24年生,对照区为25年生,品种皆为金冠。面积各为10亩。试验区内每棵树的四周距地面1.5米的树枝上均匀地挂上信息素塑料管7枚。对照区不作处理。在试验区和对照区内各设置5枚性诱剂诱捕器,定期检查
Carposina niponensis is an important insect in the apple tree in northern China. The insect sex pheromone has been widely used in monitoring and trapping prevention and treatment. This article reports the use of mating interference method to prevent peach moth test results. In this experiment, a small peach pheromone plastic tube dosage form provided by Shin-Etsu Chemical Co., Ltd. was used in 1989 in the third farm of Nankou Farm in Beijing. Pick two apples as a test area. Intercropping disturbance area apple tree is 24 years old, control area is 25 years old, all varieties are golden crown. Area of 10 acres each. In the test area, seven pheromone plastic tubes were evenly hung on the branches 1.5 meters from the ground around each tree. Control area without treatment. In the experimental area and the control area each set 5 sex attractant traps, regular inspection
