UMD Study: Pesticides not the sole cause of bee colony collapse

A new study conducted by University of Maryland scientists and published in the journal PLOS ONE points out that pesticides are not the sole cause of bee colony collapse. Click Green reveals that researchers observed the effects of imidacloprid (a strain of neonicotinoids) on bee colonies over a three year period. The times when bee colony collapse occurred was when the dosage of insecticide used was four and even twenty times more than recommended levels.

While the manuscript does not entirely absolve pesticides from having an effect on bee populations, it does point out pesticides and insecticides are factors but not the sole cause. Other factors that contribute to bee colony demise include parasites, disease, climate stress and malnutrition. The research was headed by Dr. Galen Dively emeritus professor of entomology at University of Maryland and Click Green went on to report:

For the study, Dively and his colleagues fed pollen dosed with imidacloprid to honey bee colonies. The team purposely constructed a worst-case scenario, even at lower exposure levels. For example, they fed the colonies tainted food for up to 12 continuous weeks. This is a much longer exposure than bee colonies would experience in real-world scenarios, because most crops do not bloom for such an extended period of time.

Environmentalists have used the issue of bee colony collapse and have blamed the usage of neonic pesticides as the reason why it is occurring. This University of Maryland study puts claims made that bee colonies are on the decline and it is due to a combination of neonic pesticide use to bed. As this new manuscript makes crystal clear, honey bees have a lot of things they have to deal with such as malnutrition and threats from other predators. Bee exposure to insecticides is a factor but not the sole villain leading to bee colony demise.

However, I have no doubt in my mind that despite this study’s findings it will not prevent or halt efforts on the part of environmentalists to continue to seek prohibiting neonicotinoid and other pesticides that are used to fend off insects and other pests from infesting crop yields that feed people. Environmentalists hate human beings and the best way to speed up the demise of the human race is to attack the one thing that helps sustain and enhance human populations: our food supply. Rid the planet of pesticides and the result is lower food crop production since farms that grow fruits and vegetables have a harder time preventing insects from consuming crop yields. This, in turn, results in reduced crop production which leads to hunger, starvation, and ultimately death.
