Think about some of the worst crop pests that farmers have to battle each year. The brown marmorated stink bug comes to mind, as do the bollworm, nematodes, codling moth and others. In most cases, pest advance to the “worst pest” position because their populations outnumber those of other insects, including predators. According to a study that compared insect and pathogen populations between organic and conventional farming systems, predator-prey populations seem to be more balanced in systems that use more integrated approaches to pest management.
