The beneficial insects can be used as a natural method of combating plant pests. We reveal how parasitic wasps can be used successfully against aphids, whiteflies, and the like.<\/p>\n
Ichneumonidae are beneficial insects that live as parasites. They lay their eggs to develop in insects or insect larvae, which causes them to die after the larvae hatch. As soon as all host insects have been killed, the parasitic wasp no longer holds anything on the scene and it disappears almost unnoticed. This makes it an elegant and ecological alternative to chemical crop protection.<\/p>\n
But the use of parasitic wasps should be well prepared: The useful little helpers are very specific when it comes to the choice of their host. However, you shouldn’t be put off by the high host specificity. Most parasitic wasp suppliers also provide comprehensive advice and help you make the right choice. We’ll tell you in which areas and how exactly you can use parasitic wasps.<\/p>\n
Parasitic wasps are a very species-rich family of insects. Due to a large number of different species, parasitic wasps can also be used against various pests. They are useful against both aphids (Aphidoidea) and scale insects (Coccoidea) and whitefly (Aleyrodoidea), better known as whitefly. They can be used both in closed rooms such as greenhouses or living rooms as well as outdoors. In closed rooms, the little helpers do not migrate so quickly, which is why their use is particularly effective here. Ichneumon wasps can be used at air temperatures of 15 to 30 \u00b0 C. It is therefore not recommended to use it until late spring.<\/p>\n
