Bacterial microbiota on digestive structure of Cybister lateralimarginalis torquatus (Fischer von Waldheim, 1829) (Dytiscidae: Coleoptera).

Abstract

In the List of World Edible Insects, Cybister sp. (Dytiscidae) genus of species is known to be consumed by humans. Dried Cybister lateralimarginalis torquatus (Fischer von Waldheim, 1829) which has been collected in Turkey long before and compared to other edible insects having large body, belonging to the Dytiscidae family from the aquatic beetle fauna was aimed to determine microbiota (in digestive structure) of the insect species. In this study, Lelliottia amnigena (Enterobacter amnigenus) (male insect) and Citrobacter freundii (female insect) bacteria species were detected from insect digestion structures. Finally, the DNA sequences of the obtained bacteria were matched from the Gene Bank with the accessory numbers. Moreover, levels of some heavy elements (Al, Cr, Fe, Co, Ni, Cu, Zn, As, Se, Cd, Hg, Pb) were evaluated in this study to observe whether Dytiscidae (Coleoptera) is a useful candidate for biomonitoring studies. The result of the study analyzes agricultural, ecological and health research, influence on the microbial flora and the effect of environment would be and how big the problem we would face in our future. Calculated analysis of the results will give a positive impetus and the fighting method to destroy it in the source.
