Fucans from marine algae have been the object of many studies that demonstrated a broad spectrum of biological activities, including anti-inflammatory effects. The aim of this study was to verify the protective effects of a fucan extracted from the brown algae in animals submitted to a generalized inflammation model induced by zymosan (ZIGI). BALB/c mice were first submitted to zymosan-induced peritonitis to evaluate the treatment dose capable of inhibiting the induced cellular migration in a simple model of inflammation.

- Neurotoxic compounds like organophosphates, particularly Terbufos, affect the locomotion and behavior of insects, yet their specific impact on necrophagous flies is under-researched.
- A study investigated how Terbufos influences the movement patterns of larvae from two fly species, Lucilia eximia and Peckia chrysostoma, using various doses of the compound on larvae collected from poisoned rat carcasses.
- Results showed that Terbufos affects larval activity differently based on species and dosage, with Lucilia eximia becoming more active at higher doses, while Peckia chrysostoma exhibited reduced activity, indicating the significant impact of these neurotoxicants on the behavior of these important scavenger flies.
Predation is a major process in determining the composition and dynamics of necrophagous dipteran assemblages and has implications for the colonization of cadavers. This work describes behavioural interactions between necrophagous larvae under a predator-prey perspective, using as a model the predatory species Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae) and three species of prey: Lucilia eximia (Wiedemann) (Calliphoridae), Synthesiomyia nudiseta (Wulp) (Muscidae) and Peckia (Peckia) chrysostoma (Wiedemann) (Sarcophagidae). Using experimental arenas, we observed behavioural acts, such as escape, avoidance and prey discrimination in three experiments, which also incorporated predator density.
