Which organism does NOT require control according to the IPM guidelines?

Beneficial insects play a crucial role in maintaining ecological balance and support agricultural productivity through processes such as pollination and pest control. Integrated Pest Management (IPM) principles emphasize the protection of these organisms because they provide significant ecosystem services. The aim of IPM is to manage pests while preserving beneficial species that can help in keeping pest populations under control. Thus, the focus in IPM guidelines is to optimize pest management strategies rather than eliminate all organisms, especially those that contribute positively to agriculture.

In contrast, weeds, pathogenic bacteria, and rodents can become detrimental to crops and may require management to prevent economic loss or harm to the ecosystem balance. This understanding guides the approach in IPM to focus on controlling harmful organisms while allowing beneficial ones to thrive.
