Conserving tropical forests is one of the top challenges for the future of humanity. TFs harbour most of the terrestrial biodiversity in the world, including the most species-rich group, insects. Considering that we still have some window to conserve the tropical forests and its impressive fauna, in this chapter, we cover the threats and causes of insect decline in tropical forests. Then, we shed light on the main research topics, gaps, and regions studied in recent years involving insect conservation through a bibliometric analysis of the literature. Some examples of initiatives involving insect conservation across tropical forests are highlighted and avenues to bend the curve of insect loss in tropical forests are proposed.
