Objective: To describe the Aedes aegypti container profile in the three parishes of Portland, St. Anns and St. Catherine, Jamaica.
Method: Traditional stegomyia and pupae per person indices.
Results: A total of 8855 containers were inspected. A. aegypti were breeding in 19.2% of the 4728 containers in Portland, in 6.7% of the 2639 containers in St. Ann, and in 27.2% of the 1488 containers in Tryhall Heights, St. Catherine. Container types differed between Portland (P > 0.02) on one hand and St. Ann and Tryhall Heights, St. Catherine on the other hand: there were with no vases or potted plants with water saucers in St. Ann and St. Catherine. A. aegypti were breeding in more containers in St. Catherine (38%) (38% in wet season and 21% in the dry season) than in Portland (19%) or St. Ann (6%), both of which had more containers but A. aegypti breeding in fewer: 17.7% and 11.2% in the wet and 20.4% and 3.5% in the dry seasons respectively. The daily production of adult mosquitoes in the three study sites was 1.51, 1.29 and 0.66 adult female mosquitoes per person in Portland, St. Ann and St. Catherine during the dry season and 1.12, 0.23 and 1.04 female mosquitoes per person in the wet season respectively.
Conclusion: All three communities are at risk for dengue outbreaks and vector control should concentrate on reducing the mosquito populations from the most productive containers before a new dengue virus serotype is introduced into Jamaica.

Objectives: The aim of this study was to identify chikungunya vectors and study their bioecology in order to contribute to the response to the 2020 epidemic in the cities of Abéché and Biltine in eastern Chad.
Materials And Methods: Immature stages of mosquitoes were collected and epidemic risk indices (Container index, House index and Breteau index) were calculated and compared using the Chi-square test. The collected larvae and nymphs were reared, and the resulting adults were morphologically identified using a dichotomous key.

Background: Trash piles and abandoned tires that are exposed to the elements collect water and create productive breeding grounds for Aedes aegypti mosquitoes, the primary vector for multiple arboviruses. Unmanned aerial vehicle (UAV) imaging provides a novel approach to efficiently and accurately mapping trash, which could facilitate improved prediction of Ae. aegypti habitat and consequent arbovirus transmission.

Blood meal patterns of mosquitoes (Diptera: Culicidae) are strongly influenced by host availability. However, the role of community composition and abundance of vertebrate hosts in determining such patterns is still unclear. Here, we analysed the blood meal sources of field-collected mosquitoes in settings with a permanent overabundance of a specific vertebrate species.

This study aimed to characterize microbiota composition using DNA extracted from water in artificial breeding sites, immature stages, and adults of in Leticia, Amazonas. Additionally, the physicochemical water variables were correlated with the bacterial communities present.

Annually, the Philippines is burdened by a high number of infections and deaths due to Dengue. This disease is caused by the Dengue virus (DENV) and is transmitted from one human host to another by the female mosquito. Being a developing country, most of the high-risk areas in the Philippines are resource-limited and cannot afford equipment for detection and monitoring.
