Forest ecosystems are a cornerstone of global environmental health, supporting a vast array of biodiversity, regulating climate through carbon sequestration, and providing numerous economic and cultural benefits. However, these ecosystems face significant threats from forest insect pests, which can lead to tree mortality, alter forest structure and function, and trigger cascading ecological effects. Traditional pest control methods, primarily reliant on chemical pesticides, have raised concerns due to their environmental impacts, non-target effects, and the development of resistant pest populations. In response, there is a growing emphasis on sustainable, eco-friendly pest management strategies. This chapter delves into the realm of eco-tech strategies, focusing on the intersection of biological and biotechnological innovations in forest insect pest control. These strategies represent a transformative approach, moving away from conventional chemical treatments towards methods that harness the power of nature and cutting-edge science.
