Are Bees Endangered? - What We Can Do to Help

Bees are threatened with extinction and have experienced a significant decline due to a combination of factors:

Diseases

The health of bees has been compromised by the indiscriminate use of toxins, making them more susceptible and vulnerable.

There are also a number of parasites and fungi that affect bees worldwide. For example, the invasive mite of the species Varroa destructor is the parasite with probably the greatest economic impact on the beekeeping industry. This mite causes significant damage to honey bees by weakening their immune systems and making them more susceptible to viruses. Significant mite infestation results in the death of a honey bee colony, usually in late fall to early spring. Additionally, other diseases like Nosema, a fungal parasite, have been shown to exacerbate the decline of bee colonies by impairing digestion and energy levels.

Poor nutrition

There has been a change in the nutritional status of bees recently, likely linked to the excessive use of chemicals in the plants they feed on, which ultimately impacts the quality of the food they eat. Moreover, urbanization and habitat destruction limit the availability of diverse floral resources, leading to nutritional deficits in bee populations.

Industrial agriculture

Another danger to which bees are exposed is industrial agriculture. In this case, we are dealing with a multiple cause, because industrial agriculture is linked to the endangerment of bees in several ways. Essentially, this is the destruction of natural habitats in which the different species of bees develop, in order to transform them into cultivated ecosystems that are heavily interfered with, which has great harmful effects on these insects.

On the other hand, the control of the plant diversity that grows in these areas often leads to monocultures, so that the different plant species for a healthy and adequate development of bees are significantly limited. It should be noted that monocultures not only reduce food diversity but also increase vulnerability to pests, leading to even more pesticide use.

Finally, the habitat changes described above are increasingly limiting nesting opportunities for these insects, significantly affecting their reproduction and development.

Use of insecticides and herbicides

The use of chemicals such as insecticides and herbicides is undoubtedly one of the main causes of mass mortality not only of bees, but of natural pollinators around the world in general. Chemical compounds of this type have been developed that not only remain outside plants, but also penetrate their tissues and remain over time in the cycles of plant development and production, including pollen and nectar, which are the food sources of bees, ultimately impacting the health of insects. Furthermore, neonicotinoids, a class of insecticides, have been particularly implicated in bee declines due to their persistence in the environment and sub-lethal effects on bee behavior.

Pollution

Increasing air pollution makes it difficult for bees to find the plants they feed on and eventually pollinate, because these chemical compounds mask the smell of flowers and bees can no longer detect them as they used to. Air pollutants such as ozone, sulfur dioxide, and nitrogen oxides can interfere with the volatiles emitted by flowers, thereby reducing the ability of bees to locate food sources.

Climate change

Finally, we can mention that the effects of climate change also have a negative impact on bee populations due to the change in temperatures, rainfall, and the increasing development of extreme weather events. The use of pesticides on crops poses an incredible threat to our future. In addition, climate change can lead to mismatches in the timing of flowering and bee activity, disrupting the delicate balance of pollination.

Wild bee species have attracted the most attention because, although the species that produce honey in certain regions are threatened with extinction, there are still significant populations on a global scale. However, this does not mean that they may not face extinction in the future.

The bee species that are threatened with extinction include:

• Western honey bee (Apis melifera)
• Red mason bee (Osmia bicornis)
• Red-shanked carder bee (Bombus ruderarius)
• Shrill carder bee (Bombus sylvarum)
• Great yellow bumblebee (Bombus distinguendus)
• All bees of the genus Hylaeus

In addition to these, the rusty patched bumblebee (Bombus affinis) has experienced dramatic population declines and is listed as endangered in several regions. Loss of habitat, disease, and climate change are some of the critical threats facing these bee species. If you want to know more about the different types of bees, read on in this other article where we discuss all the different types of honey bees, including the different species, pictures and their characteristics.

Among the measures we can take to prevent the extinction of bees:

• Transform current systems of industrial agriculture to organic agriculture. This change involves adopting practices that enhance biodiversity and soil health.
  
  
• Significantly limit the use of agrochemicals. Emphasizing the use of natural pest control methods can help reduce reliance on harmful chemicals.
  
  
• Minimize the use of insecticides in domestic and industrial settings. Encouraging the use of biological pest control can also be effective.
  
  
• Replace monoculture with diversely farmed land. Planting hedgerows and maintaining wildflower margins can support bee habitats.
  
  
• Stop the destruction of natural areas where bees nest. Protecting these areas ensures the preservation of bee habitats.
  
  
• Controlled reforestation of areas where bees have naturally evolved. Creating bee-friendly landscapes can foster the recovery of bee populations.
  
  
• Strengthen research and education projects in favor of the development and conservation of bees. Raising public awareness about the importance of bees is crucial for their survival.

Furthermore, individuals can contribute by planting bee-friendly gardens with a variety of flowers that bloom throughout different seasons. Supporting local beekeepers and purchasing organic produce can also have a positive impact on bee conservation efforts.
