Endemik Kum Kriketi Schizodactylus inexpectatus (Werner, 1901) (Orthoptera: Schizodactylidae)’un Biyolojisi, Nimf Evreleri ve Yaşam Alışkanlıkları

Bu çal›flma Çukurova Deltas› (Adana) ve Alata (Mersin)’da 2000-2007 tarihleri aras›nda yürütülmüfl ve ülkemiz için endemik olan kum kriketi Schizodactylus inexpectatus (Werner, 1901) (Orthoptera: Schizodactylidae)’un biyolojisi ve yaflam flekli araflt›r›lm›flt›r. Araflt›rma sonuçlar›na göre gece aktif S. inexpectatus’un 9 nimf dönemi geçirdi¤i yap›lan ölçümlerle belirlenmifltir. Her döneme ait ölçüm sonuçlar› LSD testine göre istatistiki aç›dan önemli farkl›l›klar göstermifl, her dönemin kendine has vücut büyüklü¤ü oldu¤u ortaya ç›kar›lm›flt›r. Yuva özelliklerinin de verildi¤i çal›flmada yuva derinliklerinin ergin ve ergin öncesi dönemlere göre de¤iflmedi¤i, tamamen yuva için seçilen bölgenin nem durumu ile ilgili oldu¤u ortaya ç›kar›lm›flt›r. Kannibalist özellik gösteren Schizodactylus inexpectatus’un besin tercihleri de do¤a koflullar›nda araflt›r›lm›flt›r. S. inexpectatus yok olma riski alt›ndad›r ve bu yüzden bu türün tek do¤al habitat› olarak hizmet eden kumul alanlar›n korunmas›n› amaçlayan programlar›n›n oluflturulmas› önerilmektedir. 

The Biology, Nymphal Stages, and Life Habits of the Endemic Sand Dune Cricket Schizodactylus inexpectatus (Werner, 1901) (Orthoptera: Schizodactylidae)

The biology, nymphal stages, and life habits of the endemic dune cricket Schizodactylus inexpectatus (Werner, 1901) (Orthoptera: Schizodactylidae) were investigated in this study carried out between 2000 and 2007 in the Çukurova delta (Adana province) and in Alata (Mersin province), Turkey. The study showed that S. inexpectatus, which is a nocturnal insect, passes through 9 nymphal stages, each characterised by its own body size. The present study showed that certain properties of burrows, such as their depths, do not depend on either adult or immature stages of the insect. Food preferences of cannibalistic species of S. inexpectatus were also investigated under field conditions. S. inexpectatus is at risk of extinction and therefore the establishment of conservation programmes aimed at preserving sand dunes, which serve as the only natural habitat of this species, is advised.
