Biological control examples

Biological control example

An example of biological control is the release of parasitic wasps to control aphids. Aphids are a pest of plants and cause huge damage to plants as they remove nutrients from the plant.
The parasitic wasp lays eggs in aphids, as shown in the movie. The aphids will die when the eggs come out and the young wasps start to grow. In this way the aphid population will decrease quickly.
More information about the Biocomes approach to control Aphids is found here.


Entomopathogenic nematodes to control wine weevil

Heterorhabditis bacteriophora nematodes are used to control pests such as wine weevil; their control effect is helped by releasing bacteria into the soil which attack the wine weevil.

Sclerotinia sclerotiorum controlled by fungal spores

Soil application of fungal spores of Coniothyrium minitans is used to destroy surviving structures of the common plant pathogen Sclerotinia sclerotiorum.
More information is found on the Bayer website.

Control of powdery mildew by Ampelomyces quisqualis

Another example of biological control is leaf application of fungal spores of Ampelomyces quisqualis to control mildew on greenhouse crops.
