All over the world, there is a decrease in both the number and diversity of insects. This worrying trend can be explained by several factors, including: active use of land for agriculture and construction, climate change and invasion of invasive speciesIt is a result of trade. Invasive species are non-native organisms that pose a threat to native ecosystems and species. A clear example of the damage done by invasive species can be seen in Brazil, where new fish are emerging. led to a significant reduction in the population of freshwater insects that feed on insects.

what is known

These negative factors interact closely with each other. For example, ecosystems that have been degraded by man are more susceptible to climate change, as are insect communities. Invasive species take root more easily in areas damaged by human land use and exclude native species.. While many insect species decline or disappear altogether, others, including invasive ones, thrive and multiply. All this leads to the so-called homogenization of communities – the acquisition of a more homogeneous structure, a decrease in diversity, etc.

Consequences and ways to overcome the problem

The consequences of the extinction of insects are disastrous for ecosystems.

• Thus, the loss of bumblebee diversity has led to a reduction in the number of plants pollinated by bumblebees.
• Insects not only pollinate plants, but also control pests.
• Insects are also food for many birds and animals. After losing this food source, they begin to die themselves, leading to a reduction in the number of other species that feed on them.

In the article, scientists suggest ways to better respond to negative insect trends. Standardized methods should be used to monitor diversity between countries. For species to move from one habitat to another, it is necessary to create an interconnected network of reserves. Less heat-tolerant insects will be able to migrate from areas where global warming is causing temperatures to rise to more mountainous or colder regions in the north.

Scientists also recommend controlling the spread of invasive animal and plant species from global trade and tourism.
