| 摘 要： | 在高海拔地区对甘蓝田昆虫采用不同防治措施,研究了天敌变化及天敌对害虫的控制作用。结果表明:采用性信息素防治,天敌数量及种类均明显多于化学防治田,田间主要害虫蚜虫和小菜蛾的寄生率显著高于常规化防田,蚜虫被捕食率也高于常规化防田。应用信息素防治有利于保护天敌、发挥天敌的控制作用。

| Abstract: | The population dynamic,parasitic rate and predatory rate of natural enemies were studied in chemical control field and mating disruption field.The results showed that the number of predatory natural enemies in mating disruption field was higher than that in chemical control field.At the same time,the parasitic rates of aphids or diamondback moth and the predatory rate of aphids was higher in the mating disruption control field than in chemical control field. |
