Dengue is the most important emerging tropical viral disease of humans in the world today. Aedes aegypti is a major mosquito vector responsible for transmitting many viral diseases and this mosquito that spreads major health problems like dengue fever. The resistance of Ae. aegypti to insecticides is already widespread and represents a serious problem for programmes aimed at the control and prevention of dengue in tropical countries. The search for compounds extracted from medicinal plant preparations as alternatives insecticide for mosquito control is in immediate need. Alternative approach for control Ae. aegypti dan virus dengue using the medicinal plant will be discussed in this paper.Key words: Medicinal plant, Aedes aegypti, dengue fever, dengue haemorragi fever, dengue shock syndrome

Severe human diseases are spread by mosquitoes, causing millions of deaths every year. Many well-known and severe problems have been caused by the indiscriminate use of synthetic chemical insecticides, such as the residual insecticides for humans and environment and high operating cost in addition to the possibility of developing insect resistance.The larvicidal and delayed effects of the body wall extract of Holothuria scabra and leaves extract of Acalypha fruticosa against 4th instar larvae of mosquito, Aedes aegypti were evaluated. Ethanolic extract of H. scabra recorded more larvicidal efficiency(LC50, 79.31 ppm) than A. fruticosa leaves extract (152.86 ppm) by about 1.93 folds.Morphological features showed abnormalities on the larval and pupal stages with H. scabra and to less extent with A. fruticosa. Therefore, it is possible to build on the results of this study to use these two extracts to control of A. aegypti mosquitoes and in line with recent trends in adopting combat methods that are safe on humans and the environment.

Dengue fever is an infectious disease caused by a virus and is transmitted by the Aedes aegypti mosquito. Dengue fever has not yet found a cure and the only prevention is through mosquito vector  control. Health Department policy to prevent and eradicate dengue fever today is to make eradication by means of mechanical, physical, chemical or biological. Biological is one of alternative  control of mosquito vectors that are safe for humans and the environment but still effective in suppressing the mosquito vector. One attempt to do that is by using animals to fight other creatures, or better known as biological control. In the present research was performed using fish of Betta spp, Cyprinus carpio and Oreochormis niloticus as a natural predator of the Aedes aegypti mosquito. The design of this research is  Completely Randomized Design (CRD) with three treatments are 3 types of fish with 5 times repeated. Data were analyzed with analysis of the range and tested further with the Smallest Real Differences Test (LSD) on the real level 5%. The result of this research is the ability Betta spp eating is higher than the Oreochromis niloticus and Cyprinus carpio by the number of larvae that consumed between 34.6 to 36.9 mosquito larvae tail. The ability to eat at various types of fish against mosquito larvae, influenced by several factors: the agressive, espesialisasi fish to food, the active duration and the amount of time the fish is active in 24 hours.

Dengue Vectors

Mosquitoes of Aedes species are vectors of several arboviral diseases which continue to be a major public health problem in Nigeria. This study among other things, morphologically identified Aedes mosquitoes collected from Nsukka LGA and used an allele specific PCR amplification for discrimination of dengue vectors. Larval sampling, BG-sentinel traps and modified human landing catches were used for mosquito sampling in two selected autonomous communities of Nsukka LGA (Nsukka and Obimo). A total of 124 Aedes mosquitoes consisting of five (5) different species were collected from April to June, 2019 in a cross-sectional study that covered 126 households, under 76 distinct geographical coordinates. Larvae was mainly collected from plastic containers 73% (n=224), metallic containers 14% (n=43), earthen pots 9% (n=29) and used car tyres 3% (n=9), reared to adult stage 69.35% (n=86), and all mosquitoes were identified using standard morphological keys. Five (5) Aedes mosquito species were captured; Aedes aegypti 83(66.94%), Aedes albopictus 33(26.61%), Aedes simpsoni (4.48%), Aedes luteocephalus (≤1%) and Aedes vittatus (≤1%). Nsukka autonomous community had higher species diversity than Obimo. Allele specific amplification confirmed dengue vectors, Aedes aegypti and Aedes albopictus species on a 2% agarose gel. Since the most recent re-emergence of arboviral diseases is closely associated with Aedes species, findings of this study, therefore, give further evidence about the presence of potential arboviral vectors in Nigeria and describe the role of a simple PCR in discriminating some. Further entomological studies should integrate PCR assays in mosquito vector surveillance.

Blue tansy essential oil (BTEO) ( Tanacetum annuum L.) was analyzed by GC-MS and GC-FID using two different capillary column stationary phases. Sabinene (14.0%), camphor (13.6%), myrcene (8.0%), β-pinene (7.7%), and chamazulene (6.9%) were the main components using an SE52 column (non-polar). On a polar CW20M phase column, sabinene (15.1%), camphor (14.4%), α-phellandrene (7.9%), β-pinene (7.7%), and myrcene (6.9%) were the most abundant compounds. To assess the oil for potential applications in integrated pest management strategies, behavioral bioassays were conducted to test for repellency against yellow fever mosquito Aedes aegypti, and for attractant activity for Mediterranean fruit fly Ceratitis capitata. Results showed that BTEO was not effective in repelling Ae. aegypti (minimum effective dosage [MED]: 0.625 ± 0.109 mg/cm2 compared with the standard insect repellent DEET (N,N-diethyl-3-methylbenzamide). In assays with male C. capitata, BTEO displayed mild attraction compared with two positive controls (essential oils from tea tree Melaleuca alternifolia and African ginger bush Tetradenia riparia). Additional studies are needed to identify the specific attractant chemicals in BTEO and to determine if they confer a synergistic effect when combined with other known attractants for C. capitata. To the best of our knowledge, this study represents the first investigation of BTEO for repellency against the mosquito vector Ae. aegypti and for attractancy to C. capitata, a major agricultural pest worldwide.

Introducción. Aedes aegypti y Ae. albopictus son reconocidos vectores de arbovirus como los del dengue, la fiebre amarilla, el chikungunya y el Zika, en regiones tropicales y subtropicales del mundo. En Colombia, la distribución geográfica de Ae. albopictus ha sufrido un incremento y hoy incluye ciudades como Cali y Medellín. Hasta ahora, sin embargo, no se ha recabado información concluyente sobre su infección viral y su capacidad de transmisión a los humanos.Objetivo. Determinar la infección natural por dengue en ejemplares de Ae. albopictus recolectados en un área urbana de Medellín.Materiales y métodos. Se recolectaron individuos de Ae. albopictus en el campus de la Universidad Nacional de Colombia, sede Medellín. Se confirmó su clasificación taxonómica mediante el análisis del gen citocromo oxidasa I (COI), y se extrajo el ARN total para la identificación del virus del dengue y de los respectivos serotipos. La presencia del genotipo DENV se infirió mediante el análisis del gen NS3.Resultados. El análisis del COI corroboró el estatus taxonómico de Ae. albopictus. Uno de los mosquitos procesados fue positivo para DENV-2 y el análisis del NS3 mostró una gran similitud con el genotipo asiático-americano.Conclusión. Se reporta la infección con DENV-2 en Ae. albopictus en Medellín, Colombia. La presencia del genotipo asiático-americano en una zona urbana sugiere su posible circulación entre humanos y en Ae. albopictus, lo cual alerta sobre su eventual papel en la transmisión del DENV-2, y sobre la necesidad de incluir esta especie en la vigilancia entomológica en Colombia.

Research Results

A Dengue é registrada em Curitiba/PR desde a década de 1990. A incidência da doença nesta cidade tornou-se alarmante em 2002, quando os primeiros casos autóctones foram registrados no mês de abril. Aplicando a análise rítmica dos tipos de tempo, foi possível observar como as condições climáticas foram favoráveis ao desenvolvimento do vetor (Aedes Aegypti) e, conseqüentemente, da ocorrência dos referidos casos autóctones. Os resultados desta pesquisa evidenciaram que o clima da cidade tem apresentado mudanças, tornando-se mais quente (principalmente no verão e outono), o que criou condições para a ocorrência de casos autóctones de Dengue em Curitiba. Outros aspectos ambientais também foram envolvidos na análise. Dengue Fever in Curitiba/PR: a climatological approach about March/April - 2002 event Abstract Dengue Fever has been registered in Curitiba/PR since 1990 decade. Such fact went on and became alarming in 2002, when the first autocton cases was registered in April. Applying the rhythmic analysis of weather types of, it was possible observe how the climate conditions were favorable to the vector development (Aedes Aegypti) and, consequently, the autocton cases happened. This research results showed that city climate has changed, it has become warmer than before (mainly summer and autumn), and created conditions to the occurrence of autocton cases of Dengue Fever. Others environmental aspects were also involved in this analises.
