ABSTRACT. For the first time the cytogenetic features of some grasshopper species from Israel were studied. In this paper we conducted comparative cytogenetic analysis of four Israel grasshoppers belonging to Pamphagidae (Tmethis pulchripennis (Serville, 1838) and Prionosthenus syriacus (Brisout de Barneville, 1854)) and Acrididae (Heteracris syriaca (Brunner von Wattenwyl, 1861) and Heteracris morbosa (Serville, 1838) families. We report an information on chromosome sets and C-banding patterns of studied species. P. syriacus and T. pulchripennis have karyotypes consisted of 19 acrocentric chromosomes in male (2n# = 18+X0; NF = 19). Karyotypes of H. syriaca and H. morbosa consisted of 23 acrocentric chromosomes in mail (2n# = 22+X0; NF = 23). All studied species have X0#/ XX+ sex determination. Analysis of the localization and size of C-positive regions revealed only pericentromeric C-blocs in chromosomes of studied species.
KEY WORDS: Pamphagidae, Acrididae, grasshoppers of Israel, karyotypes, autosomes, sex chromosomes, C-banding.
