A major new study published in the journal Global Ecology has found that insect populations around the world are declining at an alarming rate, with some regions seeing drops of up to 75% over the past 50 years.
The research, conducted by an international team of entomologists and ecologists, analyzed data from over 1,500 monitoring sites in 45 countries. The findings highlight habitat loss, pesticide use, climate change, and pollution as the main drivers of the decline.
"Insects are the foundation of many ecosystems—they pollinate crops, decompose organic matter, and provide food for countless species," said Dr. Maria Keller, lead author of the study. "Their disappearance will have ripple effects that could threaten food security and global biodiversity."
The study calls for immediate policy action, including stricter pesticide regulations, preservation of natural habitats, and funding for long-term insect monitoring programs.
Conservation groups have echoed the urgency of the report, urging governments and the agricultural sector to shift toward more sustainable practices. A global summit on biodiversity later this year is expected to address the issue.
