Abnormal for this time of year weather conditions lead to atypical insect behavior, the consequences of which for the following years is impossible to predict, said a senior research fellow of the Zoological Museum of Moscow state University named M.V. Lomonosov, entomologist Andrey Sviridov.
«Systematic observations about the impact of the heatwave on the behavior of insects have not yet been done, but according to the available data shows that many species have a hard time», — said the Agency interlocutor.
For example, common in Moscow moths, the so-called ribbon, found in atypical for them during the day, and show unusual behavior for them — instead, to avoid exposure of people and hide in the thickets, they can appear in public places and sit directly in the path of pedestrians.
You can observe significant deviations in the appearance of insects, which, apparently, caused by abnormal heat accompanying the development of larvae and adults.
According to the scientist, in recent times, we can mention the violation of phenology — regular alternation of insect species as changing the spring season the summer and then autumn.
«Periodic 11-year cycles of solar activity involving cyclic climatic events also lead to such violations phenology, however, in this case the changes are balanced. Today, it’s easy to see some catastrophic such changes, sometimes it is difficult to determine some changes on the background of other», — said Sviridov.
In such cases, violations of the system of feedbacks in ecosystems and food chains at the moment it is almost impossible to predict what will be the consequences on the next or subsequent years.
«In General, it can be expected that the observed because of the heat and lack of precipitation withering trees will lead to the multiplication of the respective insects», — said the scientist.
