“…However, only few chemical identifications of oviposition attractants have been conducted for Culex (Du and Millar 1999, Hwang et al 1980 and Aedes mosquitoes (Bentley et al 1979, Ponnusamy et al 2008, Sant'Ana 2003.

“…In a recent study on the essential oil from steam distillation of fresh A. occidentale leaves, 182 compounds were identifi ed, including hexadecanoic acid (Kossouoh et al 2008), which has been shown to be highly effective in inducing A. aegypti egg laying (Ponnusamy et al 2008). Although chemical analyses of the cashew leaf infusion were not performed, the presence of this carboxylic acid in the essential oil suggests its presence in the infusion, which may have an attractant potential for mosquito females.…”

-The present study investigates new sources of infusion as an oviposition attractant for Aedes aegypti L. Infusions with fetid and non-fetid odors were compared as an oviposition stimulant. Traps baited with infusions of dehydrated cashew leaves (Anacardium occidentale), potato peels (Solanum tuberosum) and graminea (Panicum maximum) were compared as attractants, and the effect of odor (fetid and unfetid) on attractiveness was tested. Oviposition activity changed signifi cantly according to the concentration and type of infusion (F = 4.1279; gl = 2; P = 0.0231). A larger number of eggs were observed in cups containing 50% A. occidentale (non-fetid odor) and 30% P. maximum (fetid odor). When compared in the same cage, comparable oviposition was found between A. occidentale and P. maximum. Moreover, approximately 20% more eggs were recorded in the infusion without odor when compared to the grass infusion and water. These fi ndings suggest A. occidentale as a new stimulant for use in ovitraps for Aedes surveillance and control, with the benefi t of having an agreeable odor.KEY WORDS: Attractive, mosquito, posture, ovitrap Epidemiologically, gravid females are the most important component of the mosquito population and are targeted in mosquito reduction programs and in the active surveillance of disease for the early detection of epidemic events (Macielde-Freitas et al 2008a). Mosquito egg traps (ovitrap) are a current trend as integral components of surveillance efforts, contributing to control efforts and monitoring of mosquito populations in countries with endemic dengue fever. This method was proven effective in detecting early infestations of Aedes aegypti L., particularly when density is low and larval indices are not good indicators (Braga et al 2000, Morato et al 2005. It is also useful in indicating critical areas for control activities (Masuh et al 2008, Regis et al 2008.There is a consensus regarding the use of organic infusions to achieve a better ovitrap performance. Most studies have used infusions of hay (Reiter et al 1991, Chadee et al 1993, Maciel-de-Freitas et al 2008b, white-oak leaf (Ponnusamy et al 2008, Trexler et al 1998, mixed grass (Regis et al 2008) and Panicum maximum (Sant'ana et al 2006, Gama et al 2007. The association of grass infusion, Eleusine indica, with the biological larvicide Bacillus thuringiensis israelensis in the fi eld has also been used (Santos et al 2003), offering the advantage of a long-term duration of traps in the wild. Recent efforts have been made to identify potential synthetic oviposition attractants/repellents for mosquitoes using certain fatty acids and esters from grass infusions (Sant'ana et al 2006) and egg extracts of A. aegypti as oviposition attractants (Ganesan et al 2006). However, different types and concentrations of organic detritus lead to variations in the abundance and types of microorganisms (Yee & Juliano 2006, Murrel & Juliano 2008, which could, in turn, infl uence the potential attraction of the infusion. Thus, the most appropriate org...

“…Em nosso trabalho, a água de criação larval foi filtrada o que, possivelmente, permitiu a remoção de microorganismos reduzindo os efeitos destes na atividade de oviposição de Aedes agypti 9 . Além disso, o fator de superpopulação larval, mecanismo regulador considerado menos favorável a oviposição, que atua como inibidor produzido pela larva, ou ainda, resultante de excesso de produto excretório 2 , pode ser descartado no presente estudo uma vez que a densidade na qual as larvas se desenvolveram (1l/3,5ml) não é considerada alta 5 11 .…”

515Revista da Sociedade Brasileira de Medicina Tropical 41(5):515-517, set-out, 2008 O sucesso reprodutivo de mosquitos está intimamente relacionado à seleção do local de oviposição, fator crítico para a sobrevivência e dinâmica de populações que influencia a distribuição larval em campo e é resultante da interação de uma complexa rede de fatores químicos e físicos, envolvendo respostas visuais, táticas e olfatórias 2 .Em Aedes aegypti, vetor dos vírus da dengue e sério problema de saúde pública no mundo, o comportamento de oviposição de fêmeas grávidas sofre a influência de fatores como a umidade, luminosidade, substrato e propriedades da água 4 7 . Diferentes autores verificaram que substâncias químicas de origem larval ou dos ovos tornam o ambiente aquático co-específico mais estimulante à deposição dos ovos 1 12 . Mendki e cols 5 isolaram e identificaram em Aedes aegypti o semioquímico de origem larval heneicosane, estimulante na oviposição desta espécie. Outros fatores químicos presentes na água de criação que estimulam a oviposição de Aedes aegypti são substâncias de origem larval heteroespecífica 1 13 e, presença de bactéria 9 .Elucidar o comportamento de oviposição de fêmeas grávidas de Aedes aegypti é um componente básico necessário com ABSTRACTTo evaluate the influence of larval rearing water on Aedes aegypti oviposition, four types of water were provided for gravid females. It was observed that more eggs were laid in the mixed larval rearing water (2,837) than in the Aedes albopictus water (690) or control water (938), but that this number was similar to what was seen in the Aedes aegypti water (2,361).
