“…As a consequence, A. aegypti is mainly controlled by assessing its breeding sites and sampling larvae and pupae in urban areas. This method is used to assess the levels of infestation in order to reduce the larvae and pupae and consequently minimize the risk of epidemics 7 . This strategy is adopted because the vector uses artificial containers that are often found within dwellings or in the peridomicile area as breeding sites 8 .…”

INTRODUCTION: Dengue is a serious public health problem worldwide, with cases reported annually in tropical and subtropical regions. Aedes aegypti (Linnaeus, 1762), the main vector of dengue, is a domiciliary species with high dispersal and survival capacities and can use various artificial containers as breeding sites. We assessed potential container breeding sites of A. aegypti in the municipality of Caxias, Maranhão, Brazil. METHODS: In the initial phase, we analyzed 900 properties in 3 neighborhoods during the dry and rainy seasons (August-October 2005 and February-April 2006, respectively). During the second sampling period, September 2006-August 2007, we used 5 assessment cycles for 300 properties in a single neighborhood. RESULTS: During the dry and rainy seasons, water-storage containers comprised 55.7% (n = 1,970) and 48.5% (n = 1,836) of the total containers inspected, and showed the highest productivity of immature A. aegypti; we found 23.7 and 106.1 individuals/container, respectively, in peridomicile sites. In intradomicile sites, water-storage containers were also the most important breeding sites with 86.4% (n = 973) and 85.6% (n = 900) of all containers and a mean of 7.9 and 108.3 individuals/container in the dry and rainy seaso-October 2006 (1,342). The highest number of positives (70) was recorded in May, mostly (94%) in storage containers. CONCLUSIONS: Storage containers are the principal and most productive A. aegypti breeding sites and are a major contributing factor to the maintenance of this vector in Caxias.

“…Strategies to combat the mosquito vector are still limited, but include the dissemination of chemicals and/or insecticidal bacteria in the environment. In fact, synthetic pesticides, chitin synthesis inhibitors (BPU's), hormone analogues and some bacterial species have been the only chemical and biological strategies developed to reduce insect proliferation (Braga & Valle 2007). However, such strategies have proven to be relatively ineffective or undesirable due to the development of resistance in mosquito populations, negative environmental impacts and the fact that the bacteria show rapid sedimentation from the larval feeding zone, UV light sensitivity and a narrow host range that has hampered their development (Porter 1996).…”

Resumo: Tremor é o distúrbio do movimento mais frequente na população, e pode estar associado a exposição a agrotóxicos. O objetivo foi avaliar a chance de tremor essencial em 442 guardas de endemias do Estado do Rio de Janeiro, Brasil, expostos a agrotóxicos. Foram selecionados 51 casos e 204 controles (1:4). Todos os participantes responderam a um questionário sobre aspectos sociodemográficos, ocupacionais e toxicológicos. A influência da exposição a agrotóxicos sobre o desenvolvimento do tremor foi estimada por regressão logística não condicional, ajustada por covariáveis selecionadas. A idade média da população estudada foi de 49 (DP = 7) anos, sendo a diferença entre casos (média = 50,8; DP = 6,9) e controles (média = 48,5; DP = 6,9) estatisticamente significativa (p = 0,03). Além disso, aqueles com 16 a 16,9 anos de aplicação de agrotóxicos foram os que estiveram sob maior chance de apresentar a doença (OR ajustada = 4,60; IC95%: 1,29-16,41). Nossos resultados sugerem que o período entre 16 e 16,9 anos de aplicação de agrotóxicos teve impacto importante para o desenvolvimento dessa doença.
