Abstract

Zemne grinje (oribatidne grinje) rasprostranjene su po cijelom svijetu i igraju bitnu ulogu ne
samo u ekosustavu kao razlagači biljnog detritusa, već i u veterinarskoj medicini zbog uloge
posrednika u razvojnom ciklusu trakavica. Trakavica Moniezia expansa je endoparazit tankog
crijeva ovaca za čiji je razvoj potrebna upravo grinja s larvalnim stadijem trakavice. Prema
dosadašnjim istraživanjima na livadama u umjerenim klimatskim područjima se nalazi
najmanje trideset do pedeset vrsta grinja. S obzirom da nema podataka o morfološkim
istraživanjima oribatidnih grinja kod nas, osnovni cilj ovog diplomskog rada bio je pronaći
oribatidne grinje na pašnjaku na kojem se napasuju ovce i morfološki ih opisati, tj.
identificirati ih. Tijekom istraživanja uzorkovana je trava pet puta kroz pet mjeseci te je
izdvojeno 2227 grinja od kojih je na 446 provedena identifikacija. Na pretraživanom pašnjaku
identificirane su tri skupine grinja. Prva i najbrojnija skupina grinja pripada rodu
Protoribates, druga skupina pripada vrsti Lucoppia burrowsii i treća pripada skupni
Brachypilina, holoidne građe tijela. Tijekom pregleda grinja nije pronađena niti jedna
invadirana ličinačkim stadijem trakavica. Potrebna su daljnja istraživanja na većem broju
uzorka i širem geografskom području kako bi se mogle determinirat i ostale vrste grinja,
između ostalog i one koje su posrednici u razvoju M. expansa.

Abstract (english)

Moss mites (Oribatid mites) are world wide distributed and play an important role not only in
the ecosystem as decomposers of plant detritus, but also in veterinary medicine due to their
role as intermediate hosts in tapeworm life cycle. Moniezia expansa is an endoparasite of the
sheep small intestine, which requires a mite containing the tapeworm larval stage. According
to previous research, in meadows in temperate climate areas, there are at least thirty to fifty
mite species. According to the fact that there are no data about morphological research on
moss mites in our country, the main goal of this research was to find oribatid mites on a
pasture where sheep graze in order to identify them and describe morphologically. During the
research, the grass was sampled five times over five months, and 2227 mites were collected,
of which 446 were used for identification. Three groups of mites were identified in
researched. The first and most numerous group of mites belongs to the genus Protoribates,
the second group belongs to the species Lucoppia burrowsii and the third belongs to the group
Brachypilina, with a holoid body structure. During the mites examination not a single mite
was found invaded with larval stages. Further research is needed on a larger sample number
and a wider geographical area in order to be able to determine other mite species, and among
others also those which are intermediate hosts in the development of M. expansa.
