Insects could completely disappear from the Earth within 100 years if they continue to decline at current rates, The Guardian notes: "More than 40% of insect species are declining and a third are endangered, the analysis found".
The total mass of insects on our planet is droppping by 2.5% a year - meaning that insects could be wiped out altogether within a century.
The review, which looked at 73 studies conducted around the world, claimed that more than 40 per cent of insect species are now declining, adding that the rate of extinction is about eight times faster than the respective rate for birds, mammals and reptiles.
The warning was issued in a global review of insect declines, in which the authors called for a dramatic rethinking of agricultural practices and better strategies for cleaning polluted waters.
Review author Francisco Sanchez-Bayo told The Guardian that if insect species loss can not be halted, it will also have catastrophic consequences for the survival of mankind.
'Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades. "The repercussions this will have for the planet's ecosystems are catastrophic to say the least", the journal warned. In 10 years you will have a quarter less, in 50 years only half left and in 100 years you will have none'.
