Ways of the biological method perfection of the upland cotton protection

It has examined the problems of cultivating the optimum planes of the work of biological fabrics by outputting the useful entomofags (trichogramma, bracon, chryzopa cornea) against the pests of the cotton (Heliothis armigera) for the different zone with using the methods modeling and programming. Mathematical models, algorithms and programs have been developed to determine the optimal timing of the emergence of the main cotton pests of cotton and winter scoop, depending on the average annual and actual data for different zones of cotton sowing in the republic. Based on these algorithms, a program was developed to determine the timing of the appearance of cotton and winter scoops and introduced in the practice of plant protection centres in the Kashkadarya, Khorezm and Namangan regions of the Republic of Uzbekistan.
