Another study confirms negative impact of pesticides on bees

bees2A new study published in the scientific journal Nature has confirmed yet again that have an adverse impact on wild . This study follows on the available research confirming that pesticides significantly harm the environment and impact on the pollination ability of .

“We saw a clear on growth and ability to reproduce in colonies near treated rapeseed fields,” said Maj Rundlöf from , the coordinator and principal investigator for the field study.

The study revealed that there are fewer wilder present on the rapeseed fields treated with pesticides. The specific tested was clothianidin on treated rapeseed fields. It’s unclear whether the study tested for the of genetically modified rapeseed plants. The researchers attribute a on the colony environment in general and the pollinating behavior of wild was modified to avoid the fields treated with this type of .

“If we only investigate how a new affects honeybees, that is not sufficient to predict the consequences for wild in a real landscape,” said Maj Rundlöf. “The results show that it is inappropriate to use clothianidin on rapeseed,” said Thorsten Rahbek Pedersen, project manager at the Swedish Board of Agriculture. “We need alternative preparations and new cultivation methods if we are to continue growing spring rapeseed in Sweden.” “We are testing new methods of dealing with flea beetles,” said Riccardo Bommarco from the Swedish University of Agricultural Sciences.
