More than 40% of insect species are threatened with extinction in the short term. So says a study conducted by the University of Sydney and published by the Scientific Journal Biological Conservation. This report places climate change and intensive agriculture as the main culprits of this disinsection, exonerating the pest control companies that are only responsible for eliminating these insects, when they pose a problem for society.

Annually there is a decrease of 2.5% of the total insect population.

A figure eight times greater than those of other animal species such as: mammals, reptiles or birds. In fact, it is estimated that with the passage of time if this number does not descend, the insects will disappear completely in 100 years.

The presented study gathers the results of 73 partial studies carried out, especially in developed countries of Europe and North America and reinforces the data that appeared in another report, where it is ensured that the insect population in Germany and Puerto Rico has dropped drastically .

According to the researchers, the elimination of insects would mean a “catastrophic collapse” throughout the world, since for many ecosystems this figure is paramount, whether as food for other creatures, to pollinate plants or recycle nutrients.


Why are insects disappearing?


The causes for which the insects are becoming extinct are diverse, being the most important the ones referring to the human being’s performance as:

  • Pollution, the use of pesticides and synthetic fertilizers
  • Urbanization and consequent loss of insect habitat.
  • Intensive agriculture
  • Climate change.
  • The study ensures that the only solution to stop the elimination of insects involves a change in agricultural practices, especially the use of pesticides and contribute by ecological and sustainable methods.

This extinction of insects does not affect all species equally. The most affected species of insects are: leipdópteros (butterflies), hymenoptera (bees, wasps or ants) and coleoptera (beetles). In addition, four aquatic orders such as: the odonata (the dragonflies), the trichoptera and the plecoptera (insects that develop in the water) have lost a considerable proportion of their species.

As the study states, insects are indispensable in our ecosystem and we only have to perform disinsection tasks, when they pose a problem for humans. Therefore, the pest control companies only act when necessary and using treatments that respect the environment.
