“…However, studies with other plants taking as base their lethal concentrations and indication for use, served as reference for the potentiality of C. reticulata oil-resin for use in C. quinquefasciatus control. Pizzarro et al (1999) studied the activity of the dehydrated gross extract and saponine fraction of Agave sisalana and estimated the lethal concentration LC 50 , LC 90 and LC 95 for 3 rd instar C. quinquefasciatus, that were 183, 408 and 512 ppm, respectively. These concentrations were much higher than those reported in this study, but these authors suggested its use for control of this mosquito.…”

Neotropical Entomology 32(4): 729-732 (2003) Atividade Larvicida do Óleo-Resina de Copaifera reticulata Sobre Culex quinquefasciatus Say (Diptera: Culicidae)RESUMO -A evolução de resistência de Culex quinquefasciatus Say aos inseticidas sintéticos e a modificação da suscetibilidade desse mosquito aos piretróides, estimularam estudos sobre a atividade de plantas inseticidas, como alternativa para o seu controle. Neste trabalho foram realizados ensaios biológicos para verificar a atividade larvicida do óleo-resina de Copaifera reticulata sobre C. quinquefasciatus. Para a realização dos bioensaios o óleo-resina foi solubilizado com dimetilsulfóxido (DMSO), na proporção de 0,4 ml do DMSO para 24,6 ml de água destilada. Para cada estádio, os bioensaios foram realizados em copos descartáveis, contendo 100 ml de solução na qual colocavam-se 20 larvas, com quatro réplicas para ajuste das concentrações letais. PALAVRAS-CHAVE: Inseticida botânico, elefantíase, controle, CulicinaeABSTRACT -The appearance of resistance of Culex quinquefasciatus Say to chemical insecticides and the modification of the susceptibility of this mosquito to pyrethroid has stimulated studies on the activity of plants as alternative for its control. In this study, bioassays were carried out to verify the larvicidal activity of the oil-resin of Copaifera reticulata on C. quinquefasciatus. The bioassays were carried out with the oil dissolved in dimethylsulfoxide (DMSO), at the proportion of 0.4 ml of DMSO to 24.6 ml of distilled water. For each instar, the bioassays were carried out in plastic glasses with 100 ml solution using 20 larvae, wit four replications to adjust the lethal concentrations. The mortality observations were made after 48h exposure of the larvae to the solution. The control was carried out in distilled water and DMSO, with the same number of replications as the bioassays. The experiments were carried out in a biological chamber, controlled at 28 ± 1°C, 80 ± 5% relative humidity and 12h light. The larvae without movement were considered dead. The C. reticulata oil-resin demonstrated larvicide activity for all the C. quinquefasciatus instars. The LC 50 found for the 1 st , 2 nd , 3 rd and 4 th larval instars were: 0.4, 0.9, 39 and 80 ppm, and the LC 99 were 15, 15, 50 and 180 ppm, respectively.

“…O mosquito Culex é transmissor da fi lariose linfática ou elefantíase que é uma doença endêmica, causada por um parasita que provoca obstruções nos vasos sangüíneos provocando inchaço, sobretudo dos membros inferiores. Pode ocorrer também linforréia (derramamento de linfa), varizes linfáticas, náuseas, febre e dor no corpo do indivíduo infectado (Pizarro et al, 1999).…”

"Chemical-biological study of the essential oils of Hyptis martiusii, Lippia sidóides and Syzigium aromaticum against larvae of Aedes aegypti and Culex quinquefasciatus." The interest for a biological assay against larvae of Aedes aegypti and Culex quinquefasciatus is due to the fact that these species are distributed by the whole national territory, being therefore an activity carried out by countless researchers of Brazil. The essential oils of Syzigium aromaticum, Hyptis martiusii and Lippia sidoides were tested in the combat of the transmitter of the dengue and of the fi lariosis, using larvae of third stadium were exposed in triplicate to different concentrations (1000, 500, 250, 100, 50, 25 and 10 ppm). The larvicidal activity was observed after ten minutes of the beginning of the treatment, in the end showed very signifi cant results, with mortality potentials of up to 100% of the tested larvae, indicating accentuated toxical effects in some representatives of the volatile compounds present in the oils. For the oils of S. aromaticum, L. sidoides and H. martiusii DL 50 of 1,0; 1,0 and 8,0 ppm, respectively, were observed. Keywords:Aedes aegypti, Culex quinquefasciatus, Hyptis martiusii, Lippia sidoides, Syzigium aromaticum, essential oil, larvicidal activity. INTRODUÇÃOO dengue é uma doença infecciosa aguda de curta duração podendo assumir formas graves e letais que vem preocupando as autoridades médico sanitárias de todo o mundo. É transmitida pelos culicídeos do gênero Aedes, especifi camente pela picada do mosquito fêmea infectado. Aedes aegypti é o principal vetor de dengue no mundo, sendo que essa espécie está amplamente distribuída nas regiões tropicais e subtropicais. No Brasil sua existência é conhecida desde o século XVII (Halsted et al., 1997).Nos últimos anos o número de casos registrados e de mortes vítimas da dengue aumentou, visto que o mosquito se tornou resistente aos inseticidas convencionais (Hemingway et al., 2000). Sabe-se que a maneira mais efi caz e ideal para o controle do dengue

“…Several studies have on focused natural products for controlling Aedes mosquitoes as insecticides and larvicides, but with varied results (Consoli et al 1988, Perich et al 1995, Jayaprakasha et al 1997, Sathiyamoorthy et al 1997, Chariandy et al 1999, Pizarro et al 1999, Rahuman et al 2000, Markouk et al 2000, Ciccia et al 2000 (Ezeonu 2001), thyme and clove (Barnard 1999) and components of essential oils such as eugenol, cineole, and citronellal (Hummelbrunner & Isman 2001) was determined in laboratory tests. Studies with Lippia sidoides (Carvalho et al 2003) and Cymbopogon citratus (Sukumar et al 1991) essentials oils suggest that they are promising as larvicides against A. aegypti.…”
