Russian scientists from the Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences have discovered an amazing phenomenon: the ash aphid has occupied all of Europe in less than two decades after being discovered on the continent. For the first time, woolly ash aphids were registered in 2003 in Budapest, and only sixteen years later they were spotted in Belarus and eight regions of the European part of Russia. It usually takes much longer for insects to spread, which is why scientists have paid such close attention to aphids. The results of the study, supported by a grant from the Russian Science Foundation (RSF), are published in the journal Forests.
The aphids are small insects, but due to their ability to reproduce quickly they can cause tremendous harm to plants not only in parks, forests or gardens, but in households as well. This seemingly harmless creature sucks the juice from the aboveground organs of plants, as a result of which the leaves curl and die off, the buds are deformed and wither, growth slows down, and the fruits stop ripening.
