Interviewed agency "Bashinform" gardeners also recorded population growth of white butterflies and expressed concern that they can cause damage to fruit and vegetable crops, once the garden pests. Specialists entomologists at the request of IA "Bashinform" insect identified by the photos as boyaryshnitsu.
According to media reports the Urals Federal District, this phenomenon is present not only in Bashkortostan. In the Middle Urals gardeners celebrate an unprecedented invasion boyaryshnits butterflies, caterpillars that cause severe damage to fruit trees and shrubs. In the vicinity of Miass, on the road towards the village Syrostan also recorded mass flight butterflies boyaryshnits.

Boyaryshnitsa spread throughout Europe as well as in North and Central Asia to Japan. In our area butterflies emerge from pupae in June.
According to experts, the butterfly itself is not dangerous to plants. However, it lays eggs, which appear in 10-15 days voracious caterpillars. They become a storm for fruit orchards. The favorite kinds of food for them are plum, pear, apple, apricot, hawthorn, mountain ash, spirea average, sloes, rosehips, cherries, cranberries.
Adult caterpillars boyaryshnitsy dark, with black and orange stripes along the body, covered with hairs. Caterpillars boyaryshnitsy susceptible to various diseases, so their massive appearance in the gardens there at intervals of several years.

Specialists of the department conduct an annual survey of forest pathology and pest control starting in the fall.
— With boyaryshnitsey in the country seriously fighting, — the head of the Raphael Naushirvanov. — Mass moths boyaryshnits forest protection experts have already fixed in 1997-98. But cause serious harm forestry tracks boyaryshnitsy then failed.
If the forest pest inspection will identify major centers, foresters will use biological control measures. And not with the butterflies, and with tracks. But, usually, nature itself regulates their numbers.

In today's mass flight chief horticulturist Republic sees nothing wrong.
— Each year, on a certain day, these butterflies fly — he said. — Just in the olden days, people did not notice. Several times I witnessed this phenomenon. It's okay for the gardens of the republic in this.
Gizyar Mansurov acknowledged that the pests in gardens this year was really more due to the fact that in the last year were good conditions for their reproduction.
