After Passing three winters in the second half of June the larva enters the stage of pupation; pupal size of about 40 mm. Marble beetle emerges from her 3 weeks later. In a shaded and cool places time of development of larvae may be renewed for another year: the stage of pupation, it enters through season 4.

The Larva of the cockchafer marble: harm

The Adult beetle beetle eats a bit, so radical harm to plants does not cause. The most dangerous pests are the larvae. Being in the stage of the first age, they feed on humus and rootlets of young plants. In the second period of development damage the roots of fruit trees and grape cuttings, than cause the death of plants. Willingly eat potato tubers, beets, garlic, onions, cabbage, canola, corn. Individuals of the third age in parallel eat up the roots of old trees. Larvae of the last year of development is able not only to cut the root of the young pines, but also gnaw the powerful tree root.marble beetle

Preferring to settle on poor soils where immunity of plants to disease and pests is lowered, marble beetle larvae cause enormous damage to young plantations of vineyards and fruit trees. Significantly increase its activity in the absence of moisture in the soil. There were cases of almost complete (70 %) destruction of the vine cuttings are planted on the banks of the Dnieper.

Biological method of protection

To combat the beetle larvae marble in several ways, which is preferably carried out in combination with the others.beetle beetle

This is a biological method, which uses the natural enemies of marble Khrushchev, in particular scolia (Scolia quadripunctata). Easy looking in the soil the larva of a potential enemy (moving towards her almost in a straight line), Scola paralyzes the victim of a prick, then lays an egg in her abdomen. Sometimes the eggs are not produced, but the shot struck the victim still dies. Subsequently this results in scolii as food uses the larva of the host – sort of always fresh food: immobilized, but with the continued circulation. Then the process of becoming a pupa and the adult insect. The latter feeds on the nectar of such flowers as singalovski, bow-headed, phacelia. Therefore, experts suggest that in the territories subject to the wrecking activities of the larvae marble Khrushchev, to plant these plants to attract scolii. Flowers recommended to sow several successive years, thus ensuring continuity of the process of destroying the pest.

Methods of struggle

In order to protect cultural spaces from marble Khrushchev, it is recommended to apply the treatment of root system of seedlings with insecticides. Contaminated soil is required to treat with pesticides.marble beetle

Marble beetle primarily inhabits areas of treeless wastelands, so in areas of its habitat is required to provide the density of trees. Fresh cutting it is recommended to take under planting young forest and old clearings is required to produce a deep plowing parallel with the introduction of chemicaldrugs. Clusters of marble of beetles on trees removed with solutions of chemicals.
