This study was conducted in Gedarif and Khartoum States to detect whether the insect found in Khartoum is similar to that in Gedarif. Adults of Pachnoda interrupta were collected from infested plants and taken to the laboratory at the Faculty of Agriculture, University of Khartoum. Specimens of sorghum chafer which were collected from both study sites were subjected to morphometric microscopic examinations, collected data were analyzed. Correlation coefficient was calculated for measurements of different parts of insect body. Observations of collected beetles revealed that the adult is black with reddish-brown margins and number of spots and stripes of the same color. Beetles have lamellate antennae, black legs with 5 tarsal segments and 2 claws; the hindwings are black transparent. Specimens of beetles collected from both states are not different in terms of the measurement of body, head, antennae, thorax, hindwings, hind legs and abdomen. Length of forewings (11.9 mm), forelegs (9.4 mm) and mid legs (12.5 mm) of specimens collected from Khartoum State were significantly higher than the respective parts of specimens collected from Gedarif State (9.2, 7.8, 9.9 mm, respectively). Correlation coefficient between different pair-wise parts of the insect body collected from the two sites of the study revealed that, the percent of the difference was 87.5%. This indicates that the specimens of the sorghum chafer which were collected from Gedarif State seem to be different from those which were collected from Khartoum State. The results recommend further studies, especially at the DNA level to confirm these findings.
