Abstract

Diplopods constitute the third largest terrestrial arthropod class, they are important soil fauna members, because they act as decomposers, participating in cycling and disposal of nutrients present in decomposing organic matter, assisting in the soil humification process. Although its population is usually formed by little groups, environmental factors may trigger population explosions that take large numbers of these animals to the urban environment, causing inconvenience to the general human population. Thus, some insecticides like deltamethrin, have been applied in order to control the diplopods invasion in residences. Such insecticide is generally characterized by having action on the nervous system, however, its effects on diplopods have not been analyzed yet. Additionally, there are few studies about the morphology and structure of diplopods nervous system. Thereby, the present project aims to elucidate the anatomy and morphology of the Gymnostreptus olivaceus species nervous system and evaluate the deltamethrin effects in this system through morphological analysis by light and confocal microscopies.
