Karyotypes and morphology of the male reproductive system of seven species of Psylloidea (Trioza abdominalis, T. cirsii, T. dispar, T. flavipennis, T. munda, T. senecionis, and Bactericera femoralis) were described for the first time.

Different morphological types of B-chromosomes in Rhinocola aceris from Katowice (southern Poland) were found for the first time in Psylloidea. Four types of supernumerary chromosomes: B1, B2, B3, and B4 were described on the basis of their morphology and heterochromatin pattern. Their behaviour during meiosis suggests a high tolerance of this species for different numbers of B-chromosomes.

Karyotypes of four species of Pachypsyllinae were reinvestigated (Pachypsylla celtidismamma, P. celtidisvesiculum, P. venusta, Pachypsylla sp. 2, and Tetragonocephala flava) in order to interpret contradiction in the literature data. The morphology of testicular follicles for three species was described for the first time.

Karyotype variation in Psylloidea (Hemiptera) was analysed. Chromosome numbers and type of chromosome sex determination of 153 species belonging to 51 genera and five out of six families (except tropical Phacopteronidae) are listed. Some important cytological characteristics, such as chromosome type, structure of karyotypes, sex determination type, pattern of male meiosis, type of chromosome rearrangements, and B chromosome occurrence, as well as the C-heterochromatin and NOR localization, are discussed. In addition, a comparison of chromosome systems between Psylloidea and other superfamilies of Sternorrhyncha (Aphidoidea, Coccoidea, and Aleyrodoidea) was undertaken.

Meiotic karyotypes were studied in males of Craspedolepta sonchi (Foerster, 1848), Diaphorina chobauti Puton, 1898, D. lamproptera Burckhardt, 1981, Psylla hartigii Flor, 1861, Cacopsylla palmeni (Loew, 1878), C. hippophaes (Foerster, 1848), C. melanoneura (Foerster, 1868), C. pyricola (Foerster 1848), C. moscovita (Andrianova, 1848), Bactericera salicivora (Reuter, 1876), Trioza abdominalis Flor, 1861, T. lauri = Lauritrioza alacris (Flor, 1861). Karyotypes were 2n = 25 (24 + XO) in all species except B. salicivora with 2n = 26 (24 + neo-XY). Testes consisted of two follicles each in all species but P. hartigii with four-follicular testes in males. The discussion covers the problems of chromosome numbers, sex-determining chromosome systems, B-chromosomes, patterns of C- banding, testis structure, and spermatid development in Psylloidea.

The karyotypes and structure of the testes were studied in 12 species of Psylloidea belonging to the families Aphalaridae, Psyllidae and Triozidae. Males of ten species, namely Aphalara avicularis Oss., A. rumicicola Klimasz., Camaratoscena speciosa (Flor), Cacopsylla ambiqua Frst., C. peregrina Frst., Bactericera curvatinervis Frst., B. striola Flor., Trioza anthrisci Burckhardt, and T. apicalis Frst. have two seminal follicles per testis, this being the most typical testis structure in Psylloidea. Males of Psylla betulaenanae Oss. and P. ledi Flor. were found to display 4 follicles per testis. Ten species share 2n=24+X0 in males, which is the basic karyotype in Psylloidea as a whole, whereas Bactericera curvatinervis Frst. and B. striola Flor. have 2n=24+neo-XY. In some karyotypes, one B-chromosome was found. Its peculiar behaviour during some stages of the first meiotic division was examined. The karyotype of A. rumicicola was studied after Giemsa C-banding. Using C-band in an autosome pair as the marker of one of the telomeres it was proved that holokinetic chromosomes of psyllids are in fact dikinetic in the first meiotic division.

Meiotic karyotypes in males of 16 species (assigned to 9 genera and 7 subfamilies) of the family Psyllidae and 3 species (assigned to 3 genera of the subfamily Triozinae) of the family Triozidae are described for the first time. The first data on the genus Ligustrinia are presented. All the species were shown to exhibit the modal karyotype for psyllids, 2n = 24 + X, except Bactericera nigricornis and Arytainilla spartiophila, in which 2n = 24 + XY and 2n = 22 + X were found, respectively. The karyotype of Ctenarytaina eucalypti (Psyllidae, Spondyliaspidinae) was reinvestigated, and the karyotype 2n = 10 + X, characteristic of Spondyliaspidinae, was revealed. The karyotypes of Strophingia fallax, S. arborea, and Craspedolepta topicalis were studied using the C-banding technique.

The study presents all data recently available on the number of follicles and arragement of their spermatocyte cysts in 132 species of psyllids representing the world fauna.Anatomical differences in the male reproductive system of psyllids and their validation for phylogenetic relations are discussed in detail.
