“…In the State of Ceará, containers used to store water, such as tanks, drums, and rooftop water tanks, predominated as the principal breeding sites of A. aegypti 18,21 . The problem of water supply was also mentioned as one of the aggravating factors in necessitating the large number of these containers in residences, as was their predominant role as breeding sites 18,19 . In other countries, such as Cuba and Nicaragua, water-storage containers were most often found to contain the largest number of immature A. aegypti [21][22][23] .…”

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.

“…16 In Ceará state, various fi sh species have been used to control the immature forms of Aedes aegypti. In the fi rst instance, under laboratory conditions, a male specimen of the Betta splendens was found to be capable of removing 500 Aedes aegypti larvae in less than 24 hours.…”

OBJECTIVE:To evaluate the effi cacy of fi sh as predators of the Aedes aegypti larvae in laboratory conditions. METHODS:The male and female of fi ve different fi sh were included in the experiment. The tests to measure their consumption ability lasted fi ve weeks for each species. Each trial involved four test tanks and four control tanks. Two control tanks contained just one fi sh, and the other two just larvae. Each of the test tanks contained one fi sh and the larvae. During the fi rst week, 100 larvae were placed in the tank, with an additional 100 added every week, up to a maximum daily amount of 500 larvae. The length and weight of the fi sh were measured at the beginning and end of every week. RESULTS:A total of 369,000 larvae were used. The Trichogaster trichopteros was the only species in which both sexes ate 100% of the available larvae. The Betta splendens failed to eat only 15 larvae. The male Poecilia reticulate showed a strong capacity for larvae eating, compared with the female of the same species. In terms of weight and size, the Betta splendens proved capable of eating 523 larvae per gram of weight per day. CONCLUSIONS:The female and male Trichogaster trichopteros and Astyanax fasciatus, and the female Betta splendens and Poecilia sphenops proved to be the most effective predators of the Aedes aegypti larvae. And although the male Poecilia sphenops and female Poecilia reticulata were less effective, they were also capable of eradicating the total number of Aedes aegypti larvae that could appear over 24 hours in a breeding site under natural conditions. The male Poecilia reticulata, however, proved incapable of doing so.

“…A adoção do controle integrado, inclusive com o uso de peixes larvófagos em depósitos domiciliares, é uma prática que já vem sendo largamente utilizada no Estado do Ceará 11 . Diante do quadro de resistência das populações de A. aegypti avaliadas é preciso que seja intensificado esse tipo de controle, como também, proceder a avaliação de amostras de populações de A. aegypti em outras localidades, além do monitoramento permanente dos produtos utilizados nas ações de controle do vetor.…”

A crescente incidência do dengue nas últimas décadas e o risco de reurbanização da febre amarela requerem estratégias efetivas e eficientes para o enfrentamento desses complexos processos ecológico-epidemiológicos pelos serviços de saúde pública no Brasil. Tradicionalmente, a principal estratégia para o controle do Aedes aegypti tem sido o uso intensivo de inseticidas para a eliminação do mosquito adulto ou de suas larvas. Para o combate ao adulto, utilizam-se com mais Resistência do Aedes aegypti ao Temefós em Municípios do Estado do CearáAedes aegypti resistance to temefos in counties of Ceará State ABSTRACTThe susceptibility of Aedes aegypti to temefos was evaluated by means of samples of eggs and larvae from four large counties in the State of Ceará (Fortaleza, Barbalha, Juazeiro do Norte and Crato). The technique standardized by the World Health Organization for tests with larvicides was used. The CL50 of eight samples from populations of Aedes was determined, as were their respective resistance ratios, compared to the CL50 of the susceptible Rockefeller strain. All populations submitted to the experiment showed resistance to temefos, with resistance ratios varying between 8 and 16. Analysis of these results reinforces prior evidence regarding the dissemination of temefos resistance in different locations in the state, subjected to considerable pressure for control in recent decades. The larvicide may lose its effectiveness if an urgent attempt is not made to reestablish the susceptibility of Aedes aegypti in these areas, profoundly affecting control campaigns currently under way.

No controle de larvas, o principal larvicida, empregado há décadas no país, é o organofosforado temefós, utilizado a 1ppm de princípio ativo, adsorvido em grãos de areia numa formulação contendo 1% dessa substância, que pode ser aplicada em água para o consumo humano, graças à sua baixa toxicidade oral para mamíferos.
