Abstract

The larva of trombidioid which parasitic on host separates from host
after enough feeding and pass to protonymph (inactive)
stage, then it passes to deutonymph stage by leaving larva skin (exuviae). In this study, the parasitic
larvae, which were collected from host and deutonymphs, which obtained from
other larvae on host, were
identified as the same species. This identification was achieved by the
comparison of larvae and exuviae that has been released while passing
deutonymph stage. With this method, three mite species, Allothrombium sp., Trichotrombidium muscarum (Riley, 1878), Trombidium holosericeum (Linnaeus, 1758) were diagnosed from
samples                                                                                                           
collected from one
harvestmen (Opilionida)

and two fly
(Diptera) species (Rhagio sp., Musca domestica). At the same time, it was determined that
larval skins, observed in previous studies but not emphasized to date, showed
the same characteristics as the larvae and could be used in morphological
diagnosis.

Trombidioid (Acari: Parasitengona) Larva Derilerinin Değerlendirilmesi ve Teşhisteki Önemi

Abstract

Konak üzerinde parazit olan trombidioid
larvası, yeteri kadar beslendikten sonra konaktan ayrılır ve protonimf
(hareketsiz) safhasına, sonrasında larva derisini atarak deutonimf safhasına
geçer. Bu çalışmada, konak üzerinden toplanan parazit larvalar ile konak üzerindeki diğer
larvalardan elde edilen deutonimflerin aynı tür olduğu tespit edildi. Bu
tespit, larvalar ile deutonimfe geçerken atılan larva derilerinin (exuviae)
karşılaştırılmasıyla sağlandı. Bu yöntemle, bir otbiçen (Opilionida) ve iki sinek (Diptera) türü (Rhagio sp., Musca domestica) üzerinden toplanan parazit akarlardan, Allothrombium sp., Trichotrombidium
muscarum (Riley, 1878) ve Trombidium
holosericeum (Linnaeus, 1758) olmak üzere üç akar türü teşhis edildi.
Aynı zamanda daha önceki çalışmalarda gözlenen ancak bugüne kadar üzerinde
durulmayan larva derilerinin, larvalar ile aynı karakteristik özellikleri
gösterdiği ve morfolojik teşhiste kullanılabileceği belirlendi
