Abstract
Insects are introduced as the largest group of animals in the animal kingdom. There is always a risk of disease outbreaks from insects that greatly affects people's health. Hundreds of thousands of species have been determined, whereas many others remained unnamed and unidentified. This study was carried out to identify the insect species obtained in Mo Cay Bac district, Ben Tre province, Vietnam, and identify the human pathogenic bacteria that parasitize on this insect. The study results showed that the insect carried Bacillus cereus and Micrococcus luteus, two strains of bacteria capable of causing festering wounds; whereas, the antibiotic Gentamicin (10 µg/mL) was shown to be capable of inhibiting Bacillus cereus and Micrococcus luteus. Based on morphological characteristics and DNA fragment of COII gene, the insect species has been identified as a species belonging to the Scatopsidae family, which belongs to complete metamorphosis. Its life cycle lasts 7-8 days and goes through 4 stages, including egg (1 day), larva (3-4 days), pupa (2-3 days), and adult. This insect species carry the biological characteristics of an entirely new insect species.
