Population Of Flying Insects Drops By 75 Percent

A new study shows that the population of flying insects across Germany's nature reserves has dropped significantly by 75 percent over a period of about 27 years. Scientists say that the drop in populations could place ecosystems in jeopardy. The 27 Years Of Study: 'An Alarming Discovery' The research, published in PLOS ONE, examines data collected from 63 nature protected areas in Germany since 1989. To gather samples and data, entomologists have been using "Malaise traps" over the course of 27 years to keep track of the number of "total insect biomass" every year. Malaise traps are tents used to capture over a thousand of samples of flying insects. They were used in spring, summer, and early autumn, operating continuously every day and night. The data were then analyzed alongside researchers from the Netherlands and England. The study reveals a 76 percent seasonal decline, and an 82 percent mid-summer drop in flying insect biomass over the 27 years of study. Caspar Hallmann of Radboud University said that the areas in which samples were collected were protected nature reserves and yet the numbers have dropped dramatically.
