Provedor de dados: 77
Autores: Ferreira,M. A. R; Lima,J. B; Rocha,R. M; Pimenta,P. F. P.
The midgut of adult female Anopheles aquasalis presents a narrow anterior or thoracic region and a distensible posterior or abdominal region constituted by the epithelium formed by a cell layer whose apical portion presents microvilli and the basal portion, a basal labyrinth. The thoracic region revealed heterogeneous cellular staining affinity mainly by the presence of acidic components. The ultrastructural aspect showed columnar cells with the presence of the vesicle, mitochondria, endoplasmic reticulum and secreting cells. The abdominal region of the midgut revealed an irregular epithelium whose cells presented a basophilic cytoplasm and acidophil granules. It was also found secreting and/or basal cells with narrow cytoplasm. The ultrastructural...

Temperature Effects on the Immature Development Time of Culex eduardoi Casal &amp;amp; García (Diptera: Culicidae)
Provedor de dados: 82
Autores: Loetti,V; Schweigmann,NJ; Burroni,NE.
The effect of constant temperatures on the development time from first instar to adult emergence was studied in Culex eduardoi Casal &amp;amp; García reared at 7, 10, 15, 20, 25, 30 or 33°C. Data were adjusted to the linear degree-day model and the nonlinear Briére model. According to the linear model, the development time was inversely related to the rearing temperatures between 7°C and 25°C. Maximum mortality (100%) was recorded at temperatures &gt; 30°C. According to the linear model, the development threshold temperature and thermal constant were 5.7°C and 188.8 degree days, respectively. The lower and upper threshold temperatures and the optimum temperature for the nonlinear model were -2.3, 30.0 and 28.1°C, respectively.

Provedor de dados: 82
Autores: ANDRADE,CARLOS F.S.; BUENO,VIRGÍNIA S.
The mosquito-repelling devices Anti-Pic®, Mosquito Repeller® DX-600 and Bye-Bye Mosquito® were evaluated in boxes for experimentation by exposing human hands to Aedes albopictus (Skuse) adults. Two sets of tests were performed based on 15 min. expositions. In the first set both hands were introduced in the box, one of them holding the device on. In the second set only one hand was introduced each time, holdind the device on or off. The devices failed to show efficiency in both evaluations. A seemingly 30.3% repellency due to Anti-Pic® in the first set of experiments was not confirmed in the second set. It was discussed the value of such devices for dengue prevention.

Provedor de dados: 82
Autores: Oliveira,Caroline D; Tadei,Wanderli P; Abdalla,Fábio C.
Cell hypertrophy was the first reaction of the gut epithelial cells of Aedes aegypti (L.), Anopheles albitarsis (Lynch-Arribálzaga) and Culex quinquefasciatus (Say) to the toxins of strains 2362 and S1116 of Bacillus sphaericus, as cells had an increase of intracellular secretory activity. Soon after the cell hypertrophy developed, vesicles were formed at the cell apical portion, which detached with the plasma membrane, characterizing a type of apocrine secretion like. The first pathway of contamination of the mosquito larvae by these bacteria is through the gut, by feeding. Depending on the species of Culicidae and on the bacterial strain used, the hypertrophy of the gut epithelium occurred between 5 and 15 min after exposure to the contaminated...

Mitochondrial DNA divergence between wild and laboratory populations of Anopheles albimanus Wiedemann (Diptera: Culicidae)
Provedor de dados: 82
Autores: Arias,Lida; Bejarano,Eduar E.; Márquez,Edna; Moncada,John; Vélez,Iván; Uribe,Sandra.
Studies of insect vectors may be facilitated by using laboratory colonies. However, it has been suggested that the colony insects are not representative of natural populations, sometimes yealding to erroneous interpretations of the intraspecific genetic variation between the individuals. In the present study the variability of the mitochondrial gene cytochrome b was evaluated among a closed laboratory colony of Anopheles albimanus that was founded 20 years ago and the field population from which it was derived. The analyses revealed the presence of five and three nucleotide haplotypes in the wild and colony populations, respectively. Wild individuals presented greater variability than those of the colony based on the number of polymorphic sites, haplotype...

Autores: Costa,Ethiene Arruda Pedrosa de Almeida; Santos,Eloína Maria de Mendonça; Correia,Juliana Cavalcanti; Albuquerque,Cleide Maria Ribeiro de.
In short space of time increase in temperature and rainfall can affect vector populations and, consequently, the diseases for them transmitted. The present study analyzed the effect of small temperature and humidity variations on the fecundity, fertility and survival of Aedes aegypti. These parameters were analyzed using individual females at temperatures ranging from 23 to 27 °C (mean 25 °C); 28 to 32 °C (mean 30 °C) and 33 to 37 °C (mean 35 ºC) associated to 60±8% and 80±6% relative humidity. Females responded to an increase in temperature by reducing egg production, oviposition time and changing oviposition patterns. At 25 ºC and 80% relative humidity, females survived two-fold more and produced 40% more eggs when compared to those kept at 35 ºC and 80%...

Provedor de dados: 92
Autores: Arcos,Adriano Nobre; Ferreira,Francisco Augusto da Silva; Cunha,Hillândia Brandão da; Tadei,Wanderli Pedro.
ABSTRACT Mosquitoes belonging to the Anopheles genus are of great relevance in the epidemiology and transmission of malaria, with their larval phase developing in clean waters in the presence of organic matter. However, the human presence in the Amazon has increasingly influenced the emergence of new breeding sites and larval habitats, such as clay pits, fish ponds and dams, among others. The objective of the study was to characterize mosquito larval habitats using the biotic and abiotic parameters in the metropolitan area of Manaus. We collected in 23 artificial larval habitats in Manaus, classified in dams, fish ponds and clay pits. Water samples, Anopheles larvae, aquatic macrophytes and limnological parameters were collected from each artificial larval...

Setting the reference for the use of Chironomus sancticaroli (Diptera: Chironomidae) as bioindicator: Ontogenetic pattern of larval head structures
Provedor de dados: 103
Autores: Rebechi,Débora; Navarro-Silva,Mário Antônio.
Species of Chironomidae are widely used as bioindicators of water quality, since their larvae undergo morphological deformities when in contact with sediment contaminated with chemicals. In this work we endeavored to study the morphology of head structures (antennae, mandible, mentum, pecten epipharyngis, ventromental plate and premandible) throughout the development of the four larval instars of Chironomus sancticaroli Strixino &amp;amp; Strixino, 1981, which can be used in environmental impact analyses. Our results show that it is possible to differentiate among larval instars by doing a quantitative analysis on the number of striae on the ventromental plates. The six structures analyzed changed during larval ontogeny. These changes are part of the...

Provedor de dados: 99
Autores: Loetti,María Verónica; Burroni,Nora E.; Prunella,Paula; Schweigmann,Nicolás.
The aim of this research was to evaluate the effect of temperature on the development time and survival of Culex (Culex) hepperi Casal and García, 1967. Individuals were reared in the laboratory, from the first larval stage to adult emergence, at five constant temperatures: 15, 20, 25, 30, and 33°C. The total development time was inversely related to temperature between 15 and 25°C. No differences were observed in the development time between sexes and no adults emerged at 33°C. In the larval stages III and IV, the time required for molting to the next stage increased at 30°C. The highest survival was recorded at 20°C. The more developed stages were less resistant to temperatures above and below 20°C. According to the nonlinear model of Briére, the lower...

ABSTRACT Control strategies using insecticides are sometimes ineffective due to the resistance of the insect vectors.In this scenario new products must be proposed for the control of insect vectors.The complexes L-aspartate Cu (II) and L-glutamate-Cu (II) complexes were synthesized and characterized by elemental analysis, visible ultraviolet, infrared spectroscopy and potentiometric titration. The toxicity of these complexes was analyzed in Aedes aegypti (Diptera: Culicidae) larvae and Gram-negative and Gram-positive bacteria. The interaction between the ligands and the amino acid balance and the distribution of the species as a function of pH were discussed. The lethal concentration median (LC50) for Ae. aegypti larvae were: L-glutamic acid-Cu (II) -...

Dimorfismo sexual alar em Aedes scapularis (Diptera: Culicidae)
Provedor de dados: 49
Autores: Devicari,Mariana; Lopes,Adriana Rios; Suesdek,Lincoln.
A detecção do sexo de mosquitos da família Culicidae é importante em estudos faunísticos e epidemiológicos, pois somente as fêmeas possuem competência vetora para patógenos. O dimorfismo sexual de genitália e de apêndices cefálicos é, em geral, facilmente visível em culicídeos. As asas também podem ser dimórficas e assim poderiam complementar o procedimento de sexagem. No entanto, tal distinção não é facilmente notável à observação direta. Visando descrever formalmente o dimorfismo sexual alar em Aedes scapularis, um culicídeo vetorialmente competente para arbovírus e filárias, asas de machos e fêmeas foram comparadas usando-se métodos de morfometria geométrica e análise estatística multivariada. Nestas análises, populações dos municípios São Paulo e...

Effect of ivermectin on the life cycle and larval fat body of Culex quinquefasciatus
Provedor de dados: 52
Autores: Alves,Stenio Nunes; Serrão,José Eduardo; Mocelin,Giovani; Melo,Alan Lane de.
The present work investigated the behavior, survival rate and lethal effect of 1.5 ppb ivermectin on Culex quinquefasciatus larvae, based on morphological and biological parameters, and possible alterations of their fat body. Changes in the number of eggs/egg mass and length of the larval stage were investigated. For this experiment, 600 larvae of 3rd and 4th instars of the mosquito were tested. The laid eggs were separated and the hatched larvae were counted. Some larvae submitted to 1.5 ppb ivermectin solution were used to prepare samples for histological study. Results obtained showed that ivermectin in a concentration of 1.5 ppb caused paralysis to the larvae with a mortality rate of 73.38%, mobilization of substances stored in the fat body and...

The polytene chromosomes of the mosquito Anopheles bellator compared with those of Anopheles cruzii
Provedor de dados: 54
Autores: Ramirez,Corolla C.L.; Dessen,Eliana M.B.
A photographic map was made of polytene chromosomes of ovarian nurse cells of Anopheles bellator females. The chromosomes of this species have complete or partial homology with those of A. cruzii, mainly in the telomeric and centromeric regions. Variability at the single band level was observed as asymmetric bands at seven different positions. One inversion (3Ra) was detected in the 3R arm.

Dirofilariose: zoonose emergente negligenciada
Provedor de dados: 65
Autores: Silva,Rodrigo Costa da; Langoni,Helio.
A dirofilariose é uma zoonose pouco conhecida causada por Dirofilaria spp., nematódeo mais conhecido como verme do coração dos cães (Dirofilaria immitis), parasita do sistema circulatório desses animais, mas que também pode acometer gatos e o ser humano. Sua ocorrência está intimamente ligada à presença de mosquitos vetores (Aedes spp., Anopheles spp., Culex spp.), condições climáticas favoráveis, assim como trânsito entre regiões indenes e endêmicas/epidêmicas. O ser humano pode se infectar com D. immitis (pulmão), Dirofilaria repens (pulmão, subcutâneo) e Dirofilaria tenuis (subcutâneo). A fisiopatologia está intimamente ligada à morte do parasita onde, no cão, pode induzir a obstrução de vasos circulatórios e no ser humano produzir uma lesão nodular com...
