Article Synopsis
- In Brazil, mosquitoes are the primary carriers of dengue, chikungunya, and Zika viruses, with an increase in dengue cases raising concerns for public health.
- The study conducted a 19-year spatiotemporal analysis of house indices (HI) related to mosquito presence, using data from the Brazilian Ministry of Health, climate data, and environmental information.
- Findings indicated a significant rise in HI surveys confirming mosquito presence, and environmental factors like urban infrastructure, rainfall, temperature, and humidity were linked to higher infestation, informing future disease control strategies.
Aedes albopictus is native to Asia and is ranked among the top 100 invasive species worldwide, with vector competence for dengue, Zika, and chikungunya viruses. Understanding Ae. albopictus dispersal is essential for effective monitoring and vector control strategies.

Consequently, it arises a challenge to public health agencies, which is the urgency use of other possibilities as botanical insecticides. Such insecticides have specific properties against insects due to the plant's ability to synthesize products derived from its secondary metabolism.

- This study documents an infection of Ascogregarina spp. in Aedes aegypti and Aedes albopictus mosquitoes in Brazil's subtropical region.
- Mosquito larvae were collected and identified from tires in four municipalities in Santa Catarina, using both morphological and molecular techniques.
- The results confirmed the presence of Ascogregarina taiwanensis through PCR, with DNA sequences archived in GenBank, indicating that both mosquito species can carry this pathogen.
Introduction:: The significant increase in dengue, Zika, and chikungunya and the resistance of the Aedes aegypti mosquito to major insecticides emphasize the importance of studying alternatives to control this vector. The aim of this study was to develop a controlled-release device containing Piper nigrum extract and to study its larvicidal activity against Aedes aegypti.
Methods:: Piper nigrum extract was produced by maceration, standardized in piperine, and incorporated into cotton threads, which were inserted into hydrogel cylinders manufactured by the extrusion of carrageenan and carob.
