For many years the use of chemical agents such as pesticides and
herbicides has been effective in controlling the many varieties of
pests that infest both agricultural crops and backyard gardens.
However, these pests are gradually becoming resistant to these
agents, because the agents themselves are acting as selective
factors making the pests better and better able to resist and
persist. As a result, the use of biological controlling agents is
increasing.
