 自制的防治蚜虫的杀虫剂

蚜虫,通常被称为植物虱子或蚜虫,是通过吸食植物汁液而进食的小昆虫。

如何检测蚜虫的存在

它的作用是通过直接观察植物上的个体,或通过植物在它面前获得的粘性外观来检测。

这是因为这些昆虫在进食时排泄糖分,在植物表面形成一个粘性层。

这一层被真菌定植是非常正常的,真菌利用可用的糖分,形成特有的黑色外观,称为fumagina。

辅助性昆虫

蚜虫活动给植物带来的主要问题是,它们因营养物质被剥离而变弱,因烟雾覆盖而减少光合作用。

这些昆虫的繁殖速度很快,因为雌性会产生其他雌性,而不需要产卵。 它们有许多天敌,最著名的是瓢虫。

在控制蚜虫种群时,我们应该始终依靠这些辅助昆虫,然而,害虫往往达到的水平证明了更快速的 "修正"。

自制的杀虫剂

有许多授权的蚜虫杀虫剂,但自制配方非常容易,它可以帮助控制害虫,对帮助昆虫的副作用较少。

其中一个选择是使用基于肥皂或洗涤剂的杀虫剂,可以在家里制作。

这种方法适用于所有小的和身体比较脆弱的昆虫,如粉蚧、蓟马、牛皮癣等,也适用于红蜘蛛等螨虫。

营养成分

  • 洗涤剂(洗碗剂)
  • 大蒜或辣椒丁香

材料

  • 花园喷雾器
  • 搅拌糖浆的勺子或器皿

准备工作:

  • 每升水稀释1茶匙洗洁精。 每升水切碎1个大蒜瓣或1个大辣椒并加入混合物。
  • 立即对植物进行喷洒,总是试图弄湿蚜虫所在的区域。 两三天后检查,必要时重复。 总是检查植物是否被肥皂灼伤。

肥皂溶解了覆盖在蚜虫身上的蜡,使它们在脱水时得不到保护。 它们是脆弱的昆虫,在使用这种混合物的几小时内就会死亡。

添加大蒜或另一种驱虫剂,如辣椒,可能会改善这种喷雾的作用,因为那些没有死亡的个体可能会有动力离开植物。

由于它们繁殖迅速,可能需要多次使用该混合物以达到充分减少个体数量的目的。

请注意,肥皂可能会损害一些植物,所以如果有疑问,请在植物的某个部分做一个小测试,看看它是否受到损害。
