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 1stand 2ndtrophic lines, as a result of which siblings of the 1storder are obtained. At the second (final) stage, the crossing of the 3rdtrophic line and siblings of the 1storder is organized, as a result of which siblings of the 2ndorder 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).1 cl, 1 dwg, 2 tbl

Opposite to the support plate and aligned with its central bore is a plunger for forming the hole in the bag and an annular heating plate which descends onto the periphery of the thus formed hole to seal it around the valve. The valve itself is fed from the side into the insertion and welding position through a feed duct. Pref. this valve feed duct has a transverse branch, along which the valve is pushed by a lever linkage into the final position. Used esp. for fitting an air valve into a plastics bag which has already been sealed along three sides, the fourth side remaining open. The appts. ensures that any flash or waste material from the punching out of the hole is extracted via the suction duct. PS.
