S.Asadov’s researches were devoted to the development and analysis of the ecological and geographical fauna of helminths, wild and domestic ruminants in various zones of Azerbaijan, measures to combat helminthic diseases of farm animals.
The scientist identified 12 new species of helminths, unknown to science. He determined the horizontal and vertical zoning of the distribution of helminthic fauna of ruminant animals throughout the territory of the Republic and divided it into 3 main ecological lowlands, foothills and mountain zones, foothills of the mountain ranges of the Greater Caucasus, Central and Eastern Azerbaijan, including heights and surrounding semi-zones.
For the first time in Azerbaijan, the plains were divided into 5 semi-zones (northeastern Azerbaijan, Absheron-Gobustan, along with the untouched parts of the desert, lowland of western Azerbaijan), the foothill zone for 4 semi-zones (Southern foothills of the Greater Caucasus, Eastern foothill areas of the Greater Caucasus, foothills, looking at the Kura-Araz plain, the foothills of the Talish mountains) and in the mountain zone of two half-zones (the heights of the Greater and Lesser Caucasus mountains).
In 1975 under leadership S.M.Asadov and the editorial board were published maps of the distribution of helminths and helminthiases of agricultural animals on zones and intensities of fighting helminthes in Azerbaijan.
