The Ecological Parasitology Laboratory was established under the leadership of academician S.Asadov In 1945in the Zoological Institute.
 "Ecosystems of helminths" laboratories (founded by professor Ismayil Alakbar oglu Sadigov) was created in 1974 but "Water animals parasites" in 1971 (founded by a doctor of biological sciences, professor Mikayilov Tofig Karrar).
 In 2013, "Helmint Ecology" and "Helmint Systematics and Biology" laboratories were merged under the name of "Helminthology" laboratory.
 On the 15th of February, 2017, "Aquaculture Parasites" and "Helminthology" laboratories were merged under the name of "Parasitology".
 Doctor of biological sciences Manafov Asif Abbas leads currently the laboratory. There are 20 employees, including 1 leading scientific worker, 7 senior research workers, one senior scientific worker, 4 scientific workers, 3 senior research workers, 4 senior lobbyists, and one laboratory assistant in the laboratory.

• Species diversity of vertebrates and plants helminths, their bioecological features, distribution of landscape-ecological zones, ways of formation of helminth fauna, determination of the epidemiological and epizootic significance of helminths and preparation of preventive measures against them, development of major helminths discovering natural warmth;

• Species diversity, distribution, origin and formation of parasites;

• Micromorphology, ultrastructure, histochemical indicators, dynamics of parasites. Biology and individual development of parasites;

• Comparative-ecological analysis of parasitic fauna of water animals, diagnosis, prevention, and treatment of parasitic diseases.

  70 types of helminths belonging to trematod, cestode, acanthosefal and nematode form in rodents has been found for the first time. 2 species among them are new for Caucasian fauna and 9 species for the fauna of Azerbaijan. 19 species of ticks have been identified intermittently by monies that parasitic animals. Of the 136 species of helminths found in wild mammals, Centrorhynchus itatsinis, Taenia servi, T.laticollis, Plagiorchis elegans, Mesocestoides corti, Passalurus nonannulatus, Bronche strongylus cubcrenatus, Pharyngostomum cordatum, Euparyphium melis, Diplopylidium skryabini, Rictularia affinis were found for the first time. A new owner for 7 types of helmets has firstly been identified. 371 types of parasites belonging to various classification groups have been studied according to the study of the species, phosphorus, echocogeny, fauna origin, and fossilization of the Caspian Sea fish parasites. Ecological, zoogeographical, and epizootic analysis of parasites has been carried out in the Azerbaijani internal water basins, especially in the waters of the Kur River basin and in the coastal zone of the Caspian Sea. Two new genus and 26 new species have been identified for science. It was identified that the unique trematode fauna found in Melanopsis praemorsa L., 1758 mollusks which is an object of complex parasitological research for the first time on the territory of Azerbaijan has not ever been found anywhere in the world and in any other owner. Micromorphological images and corresponding morphological descriptions of 33 species of cercariine noted for the first time for science have been developed and the specimen has been documented. The fauna, morphology, biology and ecology of the primitive blood parasites of fish-vertebrates (fishes, amphibians and reptiles) have also been studied. Parasitic diseases spread in fishing farms of Azerbaijan and seriously damaging fisheries have been identified and their dependence on various factors has been determined; The composition of microsporids, which interacts with owners, effects on dynamics, geographical and seasonal dissemination have been investigated in the mosquito larvae. More than 800 scientific articles and 15 monographs have been published in the laboratory on the basis of many years of research. 8 people defended their dissertations for the degree of Doctor of Sciences, and 27 people defended their dissertations for the degree of Doctor of Philosophy.
