Pest management, ecosystem: study



Washington D.C., Nov. 10: Heavy urban pollution causes serious injuries to insects and the ecosystem, according to a recent study.

The research has shown that plants that are exposed to high levels of nitrogen dioxide (NO2), similarly to large urban centers, are better protected against plant insects.

In a study by Nature Communications, the study showed that plants exposed to increased pollution produce more defensive chemicals in their leaves.

The results of the study show that the insects that feed on these leaves develop poorly, indicating that high levels of air pollution can have negative effects on the communities of herbivores.

Stuart Campbell, lead author of the study, said: "Nitrogen dioxide is a pollutant that causes serious health problems in humans, but our research has found that it can also have a significant impact on plants and insects. Insects are a key part of nature and the world, in The insects are crucial for the healthy functioning of ecosystems. "

"Many people may be aware that pollinators of insects, such as thousands of bee species, along with flies, butterflies and butterflies, are vital for food production, but they also ensure the long-term survival of crops, bushes and trees," Campbell added.

Campbell also explained that insects fed on plants (herbivorous insects) help to return plant nutrients to the soil and are food for wild birds, reptiles, mammals and more insects. Insects are also extremely important for the decomposition of organic matter that decays, and the preservation of healthy soils. Scientists point to a huge reduction in insects, which would be extremely worrying for anyone who values ​​the natural world and our food sources.

"Nitrogen dioxide is the main ingredient of smog and is an example of pollution caused by human activity, in particular our dependence on fossil fuels. The level of this pollutant in the atmosphere remains particularly high in cities and especially in the United Kingdom. An example of the risk of pollution in our environments and reasons why we must unite efforts to resolve it, "Campbell said.
