Some aspects regarding the fight against cereals beetle in the conditions of the Republic of Moldova

Abstract

Scientific research over several years has shown that the productivity of grain crops declines considerably both quantitatively and qualitatively under the influence of various harmful organisms, the population often outweighing the economic threshold of harm.Of the entire range of insect pest species, a special place and a primordial economic importance have the grubby beetle of grain. It is considered the most dangerous pest of autumn paws. Attacks numerous cultivated and spontaneous grasses, causing greater damage to wheat, barley, rye. It attacks both the adult and the larva, but produces particularly large damage to the larvae. Adults attack all the spinal organs. The biggest damage is caused by the larvae attacking the leaves, especially in the winter wheat, with a characteristic attack. They do not rotate the leaves, but chew them in the mouthpiece, extracting cellulite juice. The larval attack at first occurs in the form of winds, which gradually increase and encompass the entire culture. In large invasions, the sowing can be completely destroyed.
