A research on the decline of bee population and its impact on the world

  • CCD is a detrimental condition bees are suffering from, unfortunately the cause of which is still being hypothesized due to numerous possible causes;
  • Because of these controversial effects they are proposing to ban imidacloprid in the provinces of Ontario and Quebec;
  • Environmental Protection Agency EPA has indicated it will not approve new neonicotinoid pesticide uses;
  • Such failure to shift suggest an elevated susceptibility to rapid climate change;
  • This study also showed a reduction in pollinators caused a decrease in blueberry production;
  • There are many public health concerns that surround the agricultural industry, specifically with how our crops and food are handled and cared for.

By Steven Spence Given mounting evidence of rapidly declining bee populations, what would be the impact if there were no more bees? As we have seen, there are many other pollinatorsincluding bats and birds.

Imagine A World Without Bees To a limited extent wind pollination inefficient in most flowers and other pollinators can compensate for a lack of bees. In other cases, bees are essential. For example, the commercial growth of almonds is almost entirely dependent upon honey bees for pollination.

Do we understand why?

Certainly, pollination by bees of all kinds contributes to both the quantity and quality of many fruits and berries and would be difficult, if not impossible, to replace. Clover is one example of a plant primarily pollinated by bees that would be a major loss for livestock.

  3. One form of pollution that could be a large contributing factor to CCD are the toxins burned polluting the atmosphere.

  5. Environmental Protection Agency EPA has indicated it will not approve new neonicotinoid pesticide uses. Unknown benefits, hidden costs.

It is estimated that bees pollinate one sixth of all flowering plants and contribute to the pollination of 400 agricultural plants. Will we rely on flies instead of bees in the future? Why Are Bee Populations in Decline? Varroa Mites and Declining Bee Populations Varroa mites have had a significant impact on declining bee populations.

These mites are parasites of oriental honey bees Apis cerana. While the oriental honeybees have developed some resistance to the mitesthe European honeybee Apis mellifera and many wild bees have no such defense.

Declining Bee Populations Revisited

In the past decades the varroa mite has spread globally and is considered a major factor in stress on bee hives. Monoculture Crops and Habitat Loss While honey bees are excellent pollinators, studies have shown that many crops benefit from additional wild bees and other pollinators. The almond groves of California are a massive monoculture crop and, according to the California Almond Board1. In February of each year, beehives are trucked in for the pollination season and temporarily placed in the orchards.

The dramatic decline in Honeybee populations

However, during the rest of the year, there is nothing for wild bees to eat. A healthy honeybee visiting a backyard apple tree Fungicides, Pesticides, and Nosema ceranae The Nosema ceranae parasite primarily affects the oriental honeybee, but has been implicated in colony collapse of European honeybees. It also affects bumblebees. When bees eat pollen that is contaminated with fungicides, they may be three times more likely to be infected by Nosema ceranae than bees that consume uncontaminated pollen.

Neonicotioid pesticides may endanger bees most of all, according to two studies of declining bee populations. One study in Sweden demonstrated that bumblebees and wild bees foraging in crops treated with these pesticides were less likely to reproduce than bees that visit untreated crops.

Additionally, there were fewer bees in areas where the crops were treated with pesticides. In a second study, UK and Irish researchers demonstrated that honey bees and bumblebees prefer sugar solutions containing neonicotinoid pesticides over plain sugar solutions even though the bees ate less and were more likely to die. The feeling of reward from the sugar solution containing neonicotinoids causes the bees to prefer the pesticide-laced solution that harms them.

Speaking of Solutions Regulations are being put in place to stop the use of pesticides. The European Union has a moratorium in place on the use of neonicotinoids on certain crops. Environmental Protection Agency EPA has indicated it will not approve new neonicotinoid pesticide uses. Crop diversity could also help restore wild bee colonies and improve crop yields. Planting other types of flowers in hedgerows where there are large areas of monoculture, such as almond groves, could provide bees with food year round.

Farmlands with smaller fields and various crops blossoming at different times would also help wild bees find a healthy meal.
