Pesticides have become necessary in today’s world to guard the crops that have to support such a large consumerism. However, people might have to make some sacrifices according to recent scientific findings. A team of researchers discovered that a common pesticide in today’s industry might be at fault for weakened honey bees.
Researchers Planted Three Fields in Three Different Countries with Treated and Non-Treated Seeds
Honey bees are another reason why humans are still dependent on nature despite so many technological advancements. Without them, farmers can’t grow their crops because of lack of pollination process. Unfortunately, it has come to authorities’ attention that their population is starting to shrink down year after year.
As a consequence, scientists tried to decipher the cause of this negative phenomenon. They looked to almost all aspects, be it parasites, diseases, pesticides, and poor diet. However, none of them compare in complexity with the research paper coming from an international team from Germany, Hungary, and Britain.
They started their work by planting around 7.7 square miles with rapeseed. From this plant comes a type of cooking oil, which is called canola in America. One part of the territory received seeds treated with insecticides, and the other got seeds as they were. Afterward, researchers recorded the activity of bees in the spring of 2015. At this period, the seeds gave flowers, and new bees were born.
Pesticides Are Partly to Be Blamed for Weakened Honey Bees
The bees from the treated fields of Hungary and Britain experienced a weaker reproduction session the following period. However, the fields in Germany did them no harm. Scientists took some honey samples to their labs and discovered that their diet was more varied than other beehives.
This means that the worker bees brought back pollen from many other sources. Bees resorted only 10% to pesticide-treated crops. By comparison, the bees from Germany and Hungary didn’t go too far, and 50% of their nutrition relied on treated flowers.
This means that the controversial pesticides neonicotinoids do lead to weaker honey bees. However, the authors of the study said that the cause resembles cancer in its depth. Healthy hives can survive pesticide as long as they remain disease-free and enjoy a diverse nutrition.
