As it is known, generally recognized and widely used in many countries of the world including Uzbekistan, the so-called integrated system of plants protection (ISPP) provides carrying out of such tactics of plants protection at which number (density) of the pest(s) restrains at economic-harmless level, practically reducing their number to criterion of economic thresholds of harmful number (ETH). Control levers of such system are all possible methods, to some extent capable to lower the number of harmful organisms (organizational-economic, agro technical, mechanical, selective, genetic, biological, chemical, etc.) to economic imperceptible level. Hence, a biological method of protection of plants calculated on efficiency of not only artificially flooded bio agents (trichogramma, bracon, lacewing, etc.), but also on natural self-control of arthropods animals, is being one of the elements of ISPP. And as value of this method is great, the method of biological protection of plants is one of the basic and solving in ISPP [1-4]. Nevertheless, it is impossible to forget, that it is only one of protection methods of ISPP elements and that it is not all-powerful [6]. There are results of numerous experiences which say that in natural conditions the entomophages seldom destroy their victim on 100 %. At least for this purpose coincidence of two factors is necessary: high density and vital indicators of one or several target entomophages and adversity of climatic conditions for successful development of a harmful organism.

. Work was spent in the Andizhan area of Uzbekistan. In work methods of laboratory raring and application of entomophages [7, 8] have been used. Accounts of insects were spent according to methodical instructions [9].
