5. Khrushch or May beetle - double pest

May beetle (Melolontha) is a large polyphagous pest. The body length of an adult insect reaches 3.5-4.0 cm. The body of the May beetle is light brown or brownish brown. The flight and reproduction of the May beetle begins approximately in the second decade of May. Large white larvae with a black head, equipped with a mouth-gnawing apparatus, hatch from the eggs in 1.0-1.5 months. Their white, segmented body is folded in the shape of a fetus.

The larva of the May beetle lives and feeds in the soil for 3-4 years. By the end of the summer of the 4th year, an adult beetle emerges from the pupa, which remains in the soil until spring. In the spring, appearing on the surface of the earth, the imago begins to feed intensively. During this period, the beetle is the most dangerous pest, since the larvae in the soil damage the root system, beetles on the surface damage the flowers and vegetative mass.

May beetle danger level

Under favorable conditions, the number of May beetles increases significantly and rapidly. The threshold of harmfulness of the May beetle is 1 larva per 1 sq. m area. At present, in some regions, 2-3 larvae are recorded, and near forest belts up to 20 or more larvae per sq. m. Thus, the threshold of harmfulness has been exceeded many times over; we can talk about epiphytotic reproduction of the May beetle.

What crops are affected by the beetle and its larva?

May beetle is a polyphagous and especially dangerous pest. They harm plants by adults and larvae. Adult May beetles feed on leaves, flowers and ovaries of all fruit and ornamental trees and shrubs during the summer and breeding season (about 1-2 months a year, mainly in spring).

May beetle larvae gnaw at the roots of strawberries / strawberries, black and other types of currants, cherries, pears, apple trees (especially fond of), aspen, birch, cedar, spruce and other plants. Moreover, the appetite of the larvae of this pest increases with age. At the present time, there is a 10-year activity in the increased reproduction of the beetle and its flights to new places. Right now it is necessary to take all measures to protect plants and destroy the pest.

Signs of damage to plants by the May beetle

In plants damaged by an adult May beetle, leaf blades, buds, partially ovaries and young needles on conifers are eaten. If the roots are damaged by the larvae, the plant lags behind in development, withers, and easily breaks out of the soil.

May beetle control methods


  • May beetles and their larvae do not tolerate the smell and release of lupine, the presence of nitrogen compounds in the soil. By sowing white clover, peas and other nitrogen-fixing crops or sowing mustard and cruciferous green manures under the tree-trunk circles, it is possible to significantly reduce the number of May beetle larvae per unit area of ​​the plot.
  • During a mass flight (end of April - May) in the morning at temperatures not higher than +12.. + 15 ° С), shake the branches and collect May beetles.
  • Mulching the soil with fine mulch in the form of shavings, crushed bark, chopped straw, chopped elderberry branches, chopped mass of lupine, various crucifers, up to cabbage leaves.


The following chemicals are recommended specifically for beetle larvae.

  • Pochin and Zemlin, Aktara, Bazudin, Vallar - contact-intestinal insecticides.
  • Antichrusch is a modern environmentally friendly drug that has a long-term effect of active influence on the pest.
  • From harmless chemicals, you can use a solution of ammonia water to destroy the larvae of the May beetle.


  • Nemabact developed on the basis of a soil nematode. The biological product maintains a positive balance of pests in the soil for more than 2 years. Kills the pest within 3 days.
  • Biological products Aktofit, Boverin, Fitoverm effectively destroy the larvae of the May beetle.Before use, be sure to read the recommendations.
