METHOD FOR BREEDING PREDATORY TICKS BY INTERLINEAR CROSSING Russian patent published in 2021 - IPC A01K67/33 A23K10/18 

FIELD: biotechnology.

SUBSTANCE: invention relates to the field of biotechnology. The method for breeding siblings of predatory ticks (for example, Transeius montdorensis (Schicha), Mesostigmata: Phytoseiidae), is carried out by interlinear crossing. The method can be shown by the example of a three-line crossing of a predatory tick (Fig.), while all lines are grown on different types of feed ticks (for example, line No. 1 on the hairy tick Lepidoglyphus destructor (Schrank), line No. 2 on the narrow tick Thyreophagus entomophagus ( et Robin), line No. 3 on the dried fruit tick Carpoglyphus lactis). At the first (initial) stage, the development of biological material is organized on the basis of intermediate interlinear crossing of the 1^st and 2^nd trophic lines, as a result of which siblings of the 1^st order are obtained. At the second (final) stage, the crossing of the 3^rd trophic line and siblings of the 1^st order is organized, as a result of which siblings of the 2^nd order are obtained, which is in this case the final product.

EFFECT: resulting final biological product has increased quality indicators of vital activity, has the ability to exterminate a wide range of harmful arthropods, in particular various species of herbivorous ticks (Prostigmata), thrips (Thripidae) and whiteflies (Aleyrodidae).
