Question

Give an example of a bacterium, a fungus and an insect that are used as biocontrol agents

Answer 1

Bacteria Bacillus thuringiensis (Bt) is used to control butterfly caterpillars. By methods of genetic engineering, the genes of B. thuringiensis responsible for killing the larvae have been incorporated into the plants. The fungus Trichoderma living in roots of plants acts as a biocontrol agent against several plant pathogens. Ladybirds and dragonflies are some insects that are used to get rid of aphids and mosquitoes.

Answer 2

Insects = Ladybird and Dragonflies

Bacteria = Bacillus thuringiensis.

Fungus = Trichoderma
