German nature reserves experience massive decline in Insects

A steep drop in flying insects has been observed by Researchers in Germany. These declines were observed at several nature reserves in the past 30 years and pesticides may be responsible.

The study documented in PLOS ONE is the first of its kind to show that insects have notably decreased all through Germany in 1989.

Pesticides have been said to be responsible

Sticky traps were employed by researchers to attract insects at reserves, then the biomass was estimated.

Research provides good reason for insect drop

A 76% decline has been observed in 27 years with the pangs being felt most this summer (82%).

No reason for the drop was pinpointed by the research or by the expert contributions of consulted professionals. However several reserves were surrounded completely by farm fields and the pesticides are to blame.

Kroon, a scientist, said that the ecosystem is dependent on insects for the cause of pollination. He opined that less has to be done in order to estimate the negative impact, such as when pesticides are used.

More work has to be done at extending the reserves of nature and decreasing the percentage of reserves bordered by areas of agriculture.
