In the four typological ecosystems of the central part of the steppe zone of Ukraine, the study of apicomplex parasites for one type of beetle has been carried out. Variability of morphometric indices for the Gigaductus exiguus (Wellmer, 1911), which occurs in the intestinal tract of Pterostichus melas (Creutzer, 1799) was studied. There are significant differences in the characteristics of infection in various types of geobotanical conditions.The species of the G. exiguus is a typical unicellular parasite for P. melas. In the work 13 micrographs of gregarines are presented at different stages of life, which are extracted from the intestines. The article includes four tables of the species identification of the morphometric indices. All measurements are indicated in micrometers. The linear dimension of the gregarines gamonts is significantly different in comparison with the data of other authors. The results of morphometry for 59 detected gregarines are given: 24 organisms are presented in the form of a syzygium and 35 in the form of a gemont.
The low intensity and extensiveness of infestation by the pseudonyms for P. melas is noted. Linear characteristics and morphometric indices (n = 35) coincide with the literary data. The length of the conjugate (TL) varies from 13,65 to 46,99 (x ± SD – 26,60 ± 12,17) μm. The length of the (LP) varies between 2,44 and 10,19 (4,78 ± 2,24) μm. Deitomerite Length (LD) 10,77–41,79 (21,88 ± 10,22) μm. The width of the protomerite (WP) is 3,65–9,49 (5,51 ± 1,99) μm. The width of the deitomerite (WD) is within the range 3,85–10,58 (6,24 ± 2,28) μm. The ratio of the length of protomerite to the total length of the (LP / TL) is 0,11–0,22 (0,18 ± 0,03). The width of the protomerite to the width of the (WP / WD) is 0,77–1,03 (0,89 ± 0,07). The linear dimensions of the siziges (n = 24) coincide with the data of the researchers. The ratio of the (PTL / STL) was 0,77–1,15 (0,96 ± 0,09). The ratio of the protomerite length to the protomerite of the satellite (PPL / SPL) is 0,84–1,68 (1,25 ± 0,23). The ratio of the protomerite width of the primitive to the satellite (PPWM / SPWM) is 0,78–1,19 (1,04 ± 0,10). The ratio of the (PDL/SDL) – 0,71–1,12 (0,91 ± 0,10). The ratio of the deutorite sweep width to the satellite deutomerite width (PDWM / SDWM) is 0,89–1,18 (1,06 ± 0,07). The result of morphometry is the identification of the species as Gigaductus exiguus (Wellmer, 1911).
