Story: Insect pests of crops, pasture and forestry

Biological control of grass grubs

Biological control of grass grubs

To control grass grubs biologically, a natural enemy or disease is artificially cultivated and introduced into the soil. This pasture soil has been drilled with the bacterium Serratia entomophila. The grub on the right has become infected with amber disease and will soon die, while the grub on the left is unaffected.
