is widely known for its role as an arthropod biocontrol agent and plant bioinoculant. By using mass-production industrial methods, it is possible to produce large amounts of fungal single-celled propagules (including blastospores) to be applied in the field. However, in the environment, the solar ultraviolet components (particularly UV-B) can harm the fungus, negatively impacting its pathogenicity toward the arthropod pest.

- Aedes aegypti mosquitoes spread diseases like dengue, zika, and chikungunya, and the study investigates the use of entomopathogenic fungi, specifically Metarhizium anisopliae CG 153, as a biological control method against these mosquitoes.
- The research shows that higher concentrations of the fungus significantly decreased the survival rates of Ae. aegypti larvae (up to 95.5% reduction) and adults (with survival rates dropping to 6.7-72%) over specified monitoring periods, implying a concentration-dependent effect.
- Despite the effectiveness against larvae and adults, pupae were less affected, with survival rates between 87.8% and 100%, indicating that while M.
Evaluation of the efficacy of entomopathogenic nematodes on Ctenocephalides felis felis larvae (Siphonaptera: Pulicidae).

Ctenocephalides felis felis is a relevant and widely distributed ectoparasite that acts as a vector of disease-causing pathogens. Moreover, it is responsible for economic losses due the use of harmful chemicals to the environment and that favor the emergence of insecticide-resistant populations. Research on entomopathogenic nematodes may open up an alternative route to the insect chemical control.

In addition to its valuable amino acid composition, PP has a low environmental impact, making it a sustainable, nutritious, and viable alternative for enhanced sports performance, such as in soccer. PP Therefore, this study aimed to evaluate the effects of PP and WP supplementation on biochemical and metabolic parameters in soccer players.

Sixty-six healthy young Brazilian athletes performed a 30-minute RMR assessment. Different methods of gas exchange data selection were applied: short and long-time intervals, steady-state (SSt), and filtering.
