Karyotype analysis of Chorthippus (Glyptobothrus) bornhalmi harz, 1971 collected in the aydin

Morphological and anatomical features in addition karyological features have been used in living classification. In this study, chromosome number and morphology of Chorthippus (Glyptobothrus) bornhalmi was determined. Collected grasshoppers samples were brought to laboratory in convenient conditions, their testicles were extracted, pieces from testicles were got after the colchisin application. After the convenient processes, according to paste preparation procedure chromosome preparations were prepared. Prepared preparations were investigated under the microscophe, photographes of convenient phases were taken and karyotpe of species was determined. After the studies, chromosome number of species was determined 2n=17(XO). Three pairs of autosome chromosomes are submetasentric, five pairs and X chromosome were determineted acrosentric too. Mean chiasma frequency in 5 inviduals as a result of counts was found 15,36.
