Abstract
Insect populations have declined worldwide, with an estimated 5–10% of
species lost since the Industrial Revolution. Nearly 70% of these declines are
linked to anthropogenic pressures and climate-related stressors that disrupt
reproduction. Insects support 35% of global crop production through
pollination, biological control, and nutrient cycling, yet the extensive use of
insecticides in Asia (59% of global consumption) endangers beneficial species,
weakens pollination networks, and threatens food security. Evidence shows that
crop rotation enhances maize yields by 28.1% and reduces drought losses by up
to 89.9%, while agroforestry and ecological intensification sustain
biodiversity with reduced chemical inputs. Climate change is expected to
intensify pest pressures, with Helicoverpa armigera potentially reaching
14.2 generations annually in India by 2090 and Spodoptera frugiperda
continuing its global expansion. Conserving insect biodiversity is therefore
essential to stabilize crop yields and strengthen agroecosystem resilience
under changing climatic conditions.
