An overview of the evolution of overproduced esterases in the mosquito Culex pipiens. (1/958)

Insecticide resistance genes have developed in a wide variety of insects in response to heavy chemical application. Few of these examples of adaptation in response to rapid environmental change have been studied both at the population level and at the gene level. One of these is the evolution of the overproduced esterases that are involved in resistance to organophosphate insecticides in the mosquito Culex pipiens. At the gene level, two genetic mechanisms are involved in esterase overproduction, namely gene amplification and gene regulation. At the population level, the co-occurrence of the same amplified allele in distinct geographic areas is best explained by the importance of passive transportation at the worldwide scale. The long-term monitoring of a population of mosquitoes in southern France has enabled a detailed study to be made of the evolution of resistance genes on a local scale, and has shown that a resistance gene with a lower cost has replaced a former resistance allele with a higher cost.  (+info)

Replication of dengue type 2 virus in Culex quinquefasciatus (Diptera: Culicidae). (2/958)

We were able to infect Culex quinquefasciatus by the parenteral route with dengue virus type 2. The percentage of mosquitoes infected was dose dependent and we obtained a rate of 45.6% infected Cx. quinquefasciatus when a 10(5.9) MID50 (mosquito infectious dose for 50% of the individuals as measured in Aedes aegypti) of dengue virus type 2 per mosquito was used. Infection was detected by an immunofluorescent assay performed on mosquito head squashes 14 days after infection. The replication of dengue virus in Cx. quinquefasciatus was either at a very low level of magnitude or generated a large number of noninfectious particles since the triturated bodies of infected Cx. quinquefasciatus did not infect Ae. aegypti mosquitoes when inoculated parenterally. We were unable to infect Cx. quinquefasciatus females orally with an artificial meal that infected 100% of Ae. aegypti females. These findings lead us to agree with the consensus that Cx. quinquefasciatus should not be considered a biological vector of dengue viruses.  (+info)

Can vector control play a useful supplementary role against bancroftian filariasis? (3/958)

A single campaign of mass treatment for bancroftian filariasis with diethylcarbamazine (DEC) in Makunduchi, a town in Zanzibar, United Republic of Tanzania, combined with elimination of mosquito breeding in pit latrines with polystyrene beads was followed by a progressive decline over a 5-year period in the microfilarial rate from 49% to 3%. Evidence that vector control had contributed to this long-term decline was obtained by comparison with another town, Moga, where a DEC campaign was used without vector control and where resurgence of microfilariae could be observed 3-6 years after the campaign. In Zanzibar town, treatment of 3844 wet pit latrines and cesspits with polystyrene beads reduced the adult mosquito population in houses by about 65%. Supplementary treatment of open drains and marshes with Bacillus sphaericus produced little or no additional reduction compared to a sector of the town where only pit treatment with polystyrene was carried out. The cost and effort of achieving the 65% reduction in mosquito population could hardly be justified for its impact on filariasis alone, but its noticeable impact on biting nuisance might help to gain community support for an integrated programme.  (+info)

Bancroftian filariasis on Pemba Island, Zanzibar, Tanzania: an update on the status in urban and semi-urban communities. (4/958)

Cross-sectional clinical, parasitological and entomological surveys for bancroftian filariasis were conducted in Konde, Chake Chake and Kengeja, three urban and semiurban communities on Pemba Island, and the results were compared with similar surveys done 15 years earlier. The overall prevalences of clinical manifestations among males aged 15 years or more (n = 614) was remarkably similar to those recorded 15 years earlier: elephantiasis 1.4% in 1975 and 1.1% in 1990; hydrocele, 22.4% and 21.8%, respectively. However, when the communities were compared individually, there was a reduction in the hydrocele prevalence in Konde from 22.4% to 11.5% and an increase in Kengeja from 27.0% to 35.5%. The overall microfilarial prevalence found during night blood surveys of all individuals aged 1 year or more (n = 2687) was 9.7%, compared to 14.2% recorded in 1975. The reduction was most pronounced in Konde. Of 1052 female mosquitoes caught with CDC light traps, 95% were Culex quinquefasciatus and 5% Anopheles gambiae s.l. Infective larvae of Wuchereria bancrofti were found only in the former. The filariasis situation in urban and semiurban communities on Pemba Island appears not to have changed considerably over the last 15 years.  (+info)

Use of base excision sequence scanning for detection of genetic variations in St. Louis encephalitis virus isolates. (5/958)

Twenty-two isolates of St. Louis encephalitis (SLE) virus of various geographical origins (Brazil, Argentina, Panama, Texas, Missouri, Maryland, California, and Florida) were examined for genetic variation by the base excision sequence scanning (BESS T-scan) method. A fragment was amplified in the envelope gene with the forward primer labeled in the PCR. The BESS T-scan method determined different clusters according to the profiles generated for the isolates and successfully grouped the isolates according to their geographical origins. Two major clusters, the North American cluster (cluster A) and the South and Central American cluster (cluster B), were defined. Two subgroups, the Texas-California subgroup (subgroup A1) and the Missouri-Maryland-Florida subgroup (subgroup A2), were distinguished within group A. Similarly, group B strains were subclustered to a South American subgroup (subgroup B1) and a Central American subgroup (subgroup B2). These results were consistent with those obtained by DNA sequencing analysis. The ability of the BESS T-scan method to discriminate between strains that present with high degrees of nucleotide sequence similarity indicated that this method provides reliable results and multiple applications for other virus families. The method has proven to be suitable for phylogenetic comparison and molecular epidemiology studies and may be an alternative to DNA sequencing.  (+info)

Study on the transmission threshold value of bancroftian filariasis. (6/958)

OBJECTIVE: To elucidate the transmission dynamic and epidemic trend of bancroftian filariasis occurred under the condition with no control measure taken 5 years after elimination of filariasis. METHODS: A 10-year longitudinal observation (from 1984 to 1994) was made in Huayuan Village in Shengli Township of Tancheng County, which used to be a high bancroftian filariasis-endemic area in southern part of Shandong Province. RESULTS: The microfilarial rate decreased from 0.56% before the study to 0.12% after the study and 8 out of the 9 previous microfilaria-positive cases became negative gradually. During the study period, 6 new microfilaremia cases were detected, 5 of which became negative naturally within 3 to 4 years. Eighty-eight point eight nine per cent of the detected patients with microfilaremia converted into IgG4-negative after 10 years. The natural infective rate of vectors decreased year by year and became zero by the tenth year of the study, the annual transmission potency decreased also from 3.47 to zero by the tenth year. CONCLUSIONS: It showed that under the local natural environment the biting rate representing the vector density which was obtained by capture method was from 24.1 to 52.5 person/night among the residents who did not use mosquito nets, and 13.5 to 21 person/night among the residents who used mosquito nets. The microfilarial rate of 0.56% in population with the average microfilarial density of 6.6 to 20.7 capita/60 microliters ear blood of residual microfilaria-positive patients might be considered as the terminal threshold of transmission.  (+info)

Model ecosystem evaluation of the environmental impacts of the veterinary drugs phenothiazine, sulfamethazine, clopidol, and diethylstilbestrol. (7/958)

Four veterinary drugs of dissimilar chemical structures were evaluated for environmental stability and penchant for bioaccumulation. The techniques used were (1) a model aquatic ecosystem (3 days) and (2) a model feedlot ecosystem (33 days) in which the drugs were introduced via the excreta of chicks or mice. The model feedlot ecosystem was supported by metabolism cage studies to determine the amount and the form of the drug excreted by the chicks or mice. Considerable quantities of all the drugs were excreted intact or as environmentally short-lived conjugates. Diethylstilbestrol (DES) and Clopidol were the most persistent molecules, but only DES bioaccumulated to any appreciable degree. Phenothiazine was very biodegradable; sulfamethazine was relatively biodegradable and only accumulated in the organisms to very low levels. Data from the aquatic model ecosystem demonstrated a good correlation between the partition coefficients of the drugs and their accumulation in the fish.  (+info)

Production of Cry11A and Cry11Ba toxins in Bacillus sphaericus confers toxicity towards Aedes aegypti and resistant Culex populations. (8/958)

Cry11A from Bacillus thuringiensis subsp. israelensis and Cry11Ba from Bacillus thuringiensis subsp. jegathesan were introduced, separately and in combination, into the chromosome of Bacillus sphaericus 2297 by in vivo recombination. Two loci on the B. sphaericus chromosome were chosen as target sites for recombination: the binary toxin locus and the gene encoding the 36-kDa protease that may be responsible for the cleavage of the Mtx protein. Disruption of the protease gene did not increase the larvicidal activity of the recombinant strain against Aedes aegypti and Culex pipiens. Synthesis of the Cry11A and Cry11Ba toxins made the recombinant strains toxic to A. aegypti larvae to which the parental strain was not toxic. The strain containing Cry11Ba was more toxic than strains containing the added Cry11A or both Cry11A and Cry11Ba. The production of the two toxins together with the binary toxin did not significantly increase the toxicity of the recombinant strain to susceptible C. pipiens larvae. However, the production of Cry11A and/or Cry11Ba partially overcame the resistance of C. pipiens SPHAE and Culex quinquefasciatus GeoR to B. sphaericus strain 2297.  (+info)

Abstract. The mosquito-transmitted pathogen West Nile virus (WNV) is not yet present in the Galápagos Archipelago of Ecuador. However, concern exists for fragile endemic island fauna after population decreases in several North American bird species and pathology in certain reptiles. We examined WNV vector competency of a Galápagos strain of mosquito (Culex quinquefasciatus Say). Field specimens were tested for their capacity to transmit the WN02-1956 strain of WNV after incubation at 27°C or 30°C. Rates of infection, dissemination, and transmission all increased with days post-exposure to WNV, and the highest rates were observed at 28 days. Infection rates peaked at 59% and transmission rates peaked at 44% (of mosquitoes tested). Vector efficiency increased after day 14. Rates of infection but not of transmission were significantly influence by temperature. No vertical transmission was detectable. We demonstrate that Galápagos Cx. quinquefasciatus are competent WNV vectors, and therefore should be

Florida SLE Mosquito - Culex nigripalpus TheobaldFlorida SLE Mosquito - Culex nigripalpus Theobald
Due to the medical significance of this species, vector surveillance, with the ultimate goal of predicting human cases of SLE virus, is of critical importance. Historically, New Jersey light traps and CDC miniature light traps have been used to monitor the abundance of Culex nigripalpus adults. However, we have found that resting collections made with ground aspirators, provide a superior measure of Culex nigripalpus adult populations. This is because males as well as females in all gonotrophic conditions (host seeking, blood fed, partially blood fed and gravid) are taken in aspirator collections. Due to their green color, newly emerged adults of both sexes can be identified and counted, thus providing an accurate measure of adult emergence. Because Culex nigripalpus females prefer to lay their eggs in freshly flooded ditches, huge numbers of adults are often observed during the wet summer months in south Florida. The vast number of breeding habitats in which this species is found results in ...

Coloured scanning electron micrograph (SEM) of Common house mosquito (Culex pipiens). A female mosquito with prominent antenna and proboscis. Culex species lay their eggs in the form of egg rafts that float in still or stagnant water. In the United States, West Nile virus is transmitted primarily by Culex pipiens mosquitoes. Culex spp. become infected by biting certain birds carrying the West Nile virus and in turn transmits the virus to humans where it can cause encephalitis and meningitis. Culex spp. are also disease vectors of western equine and Saint Louis encephalitis. In addition, Culex spp. are carriers of viral encephalitis and filariasis.

Abstract St. Louis encephalitis (SLE) virus has continued to be active in the Colorado Desert region of Southern California (Coachella and Imperial Valleys) since 1973, while it has virtually disappeared from the Sacramento and San Joaquin Valleys of Central California. Consequently, comparative vector competence studies were undertaken from 1978 to 1981 to evaluate the susceptibility of populations of Culex quinquefasciatus and Culex tarsalis from the San Joaquin and Coachella/Imperial Valleys to oral infection with representative SLE viral strains from each geographical area. Culex quinquefasciatus females from both areas were equally susceptible to infection with both viral strains by the pledget and viremic chick feeding techniques. Although susceptibility profiles were similar by both feeding techniques, infection thresholds (i.e., ID50s) obtained with Cx. quinquefasciatus females were at least 10,000-fold lower when fed on viremic chicks than on virus soaked pledgets.

The Coronator Group encompasses Culex coronator Dyar & Knab, Culex camposi Dyar, Culex covagarciai Forattini, Culex ousqua Dyar, Culex usquatissimus Dyar, Culex usquatus Dyar and Culex yojoae Strickman. Culex coronator has the largest geographic distribution, occurring in North, Central and South America. Moreover, it is a potential vector-borne mosquito species because females have been found naturally infected with several arboviruses, i.e., Saint Louis Encephalitis Virus, Venezuelan Equine Encephalitis Virus and West Nile Virus. Considering the epidemiological importance of Cx. coronator, we investigated the wing shape diversity of Cx. coronator from South and Southeast Brazil, a method to preliminarily estimate population diversity. Field-collected immature stages of seven populations from a large geographical area in Brazil were maintained in the laboratory to obtain both females and males linked with pupal and/or larval exuviae. For each individual female, 18 landmarks of left wings were marked
First report on human-biting Culex pipiens in Sweden | Parasites & Vectors | Full TextFirst report on human-biting Culex pipiens in Sweden | Parasites & Vectors | Full Text
Mosquitoes of the genus Culex are the vectors of bird-hosted arboviruses that occasionally cause disease in humans, such as Sindbis virus (SINV) (Alphavirus) West Nile virus (WNV) and Usutu virus (USUV) (Flavivirus), all circulating in Europe. Seven potential vector species are recognised within the genus Culex in Europe, most of which show a preference for biting birds (ornithophilic). One of the species, the northern house mosquito Cx. pipiens, has been described as having two separate biotypes: Cx. pipiens biotype pipiens and Cx. pipiens biotype molestus, of which the latter fulfils certain criteria that separates it from the other: it does not hibernate in winter (homodynamic), it utilizes underground larval habitat (hypogeous), it can mate in confined spaces (stenogamous), it can lay its first egg batch without a blood meal (autogenous), and it feeds on humans (mammophilic). Culex pipiens biotype molestus has been reported from many central and southern European countries but never from ...

Surprising genetic differences id-ed in southern house mosquitoSurprising genetic differences id-ed in southern house mosquito
In a paper published in the February issue of the American Journal of Tropical Medicine and Hygiene, Dr. Dina Fonseca and her team identified different strains of the southern house mosquito (Culex quinquefasciatus). Until now, researchers were unaware that this one species of mosquito could have consistent variations in its genetic makeup and that the geographical distribution of the mosquito variants explained the occurrence of serious diseases. The diseases include elephantiasis (a disfiguring disease), West Nile virus and other encephalitides, avian malaria and poxvirus. "The surprising thing is that there is actually structure in this mosquito. Researchers had thought that all populations of this mosquito were the same," explained Fonseca, who was the first to examine the genetic makeup of this important disease transmitter ...

Two species of arbovirus vector, Culex torrentium and Culex pipiens (Diptera: Culicidae), occur in several European countries, but difficulties in their accurate identification and discrimination have hampered both detailed and large-scale distribution and abundance studies. Using a molecular identification method, we identified to species 2559 larvae of Cx. pipiens/torrentium collected from 138 sites in 13 European countries ranging from Scandinavia to the Mediterranean coast. In addition, samples of 1712 males of Cx. pipiens/torrentium collected at several sites in the Czech Republic were identified to species based on the morphology of their hypopygia. We found that the two species occur together in large areas of Europe, and that Cx. torrentium dominates in northern Europe and Cx. pipiens dominates south of the Alps. The transition in dominance occurs in central Europe, where both species are roughly equally common. There was a strong correlation between the length of the growing season at ...
Molecular characterization of adult diapause in the northern house mosquito, Culex Pipiens - OpenThesisMolecular characterization of adult diapause in the northern house mosquito, Culex Pipiens - OpenThesis
One of the primary avian vectors of West Nile virus in the northern United States, Culex pipiens (L.), enters an adult diapause in late summer and early fall in response to short daylength and low temperature. The mosquitoes first appear in overwintering sites such as caves, culverts, and unheated basements as early as August and remain there until spring when environmental conditions again become favorable for development. Only females enter diapause and most are inseminated prior to entering the hibernation site. In preparation for diapause, females increase their lipid reserves by feeding on sugar-rich sources such as nectar and rotting fruit. Although females programmed for diapause can be enticed to take a blood meal by being placed in close proximity to a host, it appears this rarely, if ever, happens in the field. Failure of diapausing females to take a blood meal is presumably the reason that so few of the overwintering females harbor West Nile virus. Many aspects of diapause in Cx. ...

The Culex pipiens subgroup of mosquitoes contains some of the most important vector species internationally. In Australia, there are four species currently present that belong to that subgroup, with Culex molestus one species that is closely associated with urban environments, and concern has been raised as to the potential role this species may play in the transmission of exotic and endemic Flaviviruses. An understanding of the biology and ecology of this species is crucial for the establishment of laboratory colonies and further experimentation. Using field‐collected adult mosquitoes, a laboratory colony of Cx. molestus was established and sustained for 10 generations. The species was strongly stenogamous and, across all generations, over 95% of females laid autogenous egg rafts with a mean egg raft size of 54.2 ± 17.7 eggs. The females did not display a preference for highly organic oviposition water and readily laid eggs in clean water. While colony maintenance could be sustained on ...
Effects of halofenozide (RH-0345) on cuticular hydrocarbons of mosquito larvae of Culex pipiens - Université de BourgogneEffects of halofenozide (RH-0345) on cuticular hydrocarbons of mosquito larvae of Culex pipiens - Université de Bourgogne
Insect cuticular hydrocarbons are known to have a protection and a pheromonal role. Quantitative changes in the cuticular hydrocarbons of Diptera occur over time and were used in a preliminary attempt to age-grade of mosquitoes. Halofenozide (RH-0345) is an insect growth regulator belonging to the class of non-steroidal ecdysone agonists. In a previous study, halofenozide was found to be effective against larvae of Culex pipiens L. (Diptera: Culicidae) and exerted its toxicity primarily by the induction of a precocious lethal molting (Boudjelida et al., 2005). In this study, newly molted 4th instar larvae of C. pipiens were exposed to halofenozide (23% EC) for 24 h at LC50 (12.58 µg/l) and LC90 (28.58µg/l) concentrations under standard laboratory conditions according to WHO recommendations. Then, to better understand the mode of action of halofenozide, the profiles of the cuticular hydrocarbons in treated and control larvae were evaluated using gas chromatography (GC) and gas chromatography-mass

Cry4Ba is a δ-endotoxin produced by Bacillus thuringiensis subsp. israelensis and Cyt2Aa2 is a cytolytic δ-endotoxin produced by B. thuringiensis subsp. darmstadiensis. Cry4Ba produced in Escherichia coli was toxic to Aedes aegypti larvae (LC50= 140 ng ml-1) but virtually inactive to Culex quinquefasciatus larvae. Cyt2Aa2 expressed in E. coli exhibited moderate activity against A. aegypti and C. quinquefasciatus larvae with LC50values of 350 and 250 ng ml-1, respectively. Co-expression of both toxins in E. coli dramatically increased toxicity to both A. aegypti andC. quinquefasciatus larvae (LC50= 7 and 20 ng ml-1, respectively).

Aedes aegypti (Yellowfever mosquito) (Culex aegypti)Aedes aegypti (Yellowfever mosquito) (Culex aegypti)
Aedes aegypti is the principal vector of the etiological agents of yellow fever, dengue fever and chikungunya fever. In 1901, Walter Reed and colleagues showed that yellow fever was transmitted by Aedes aegypti. Their work was based on Carlos Finlays hypothesis that mosquito bites could transmit the organism causing the disease. Due to its easy adaptation to laboratory culture it is the most studied species within the Culicinae, and has extensively contributed to our understanding of mosquito biology, physiology, genetics, and vector competence.. The Aedes aegypti complete genome sequence was first published in 2007. About 47% of the genome consists of transposable elements, probably contributing to the expansion in size and organization of the Aedes aegypti genome over time. ...

Board of Health combating Culex mosquitoes - The Boston GlobeBoard of Health combating Culex mosquitoes - The Boston Globe
The Andover Board of Health is advising residents to drain any standing water on their property to prevent their yard from becoming a source of mosquitoes, which thrive in water-holding containers, including birdbaths, childrens toys, stored tires, and clogged gutters. Residents should also ensure that air conditioner drip pans are empty and that water features in landscaping are aerated with pumps. Mosquitoes are the primary vectors transmitters of West Nile virus, a virus that can cause fever, meningitis, or encephalitis. Early symptoms include fever, headache, stiff neck, and muscle weakness. A sumithrin-based insecticide with low mammalian toxicity recently was sprayed south of Route 133, from the Tewksbury line to Bellevue Road, along Bellevue Road and Blanchard Street and the nearby side streets, to address the recent discovery of mosquitoes in Tewksbury that tested positive for West Nile virus.

DISTRIBUTION AND MOLECULAR ANALYSIS OF AVIAN MALARIA VECTORS ON FOUR C by Catherine Wallace"DISTRIBUTION AND MOLECULAR ANALYSIS OF AVIAN MALARIA VECTORS ON FOUR C" by Catherine Wallace
Avian malaria is a devastating disease that has decimated numerous bird species. This study sought to identify the vectors of avian malaria at four central Virginia Prothonotary warbler breeding sites. Twenty one thousand mosquitoes were collected and Culex salinarius, Cx. erraticus, and Cx. pipiens/restuans were found to be the dominant species at these sites. Geographic factors, such as crop land and forest type, were determined to be potential indicators for species abundance variation between sites. Of the mosquitoes collected, ninety one (0.4%) were identified as blood fed. The blood fed mosquitoes were found to have fed on avian, mammalian, amphibian, and reptilian hosts and a 12.1% Plasmodium infection rate. Of the non-blood fed mosquito pools tested, Deep Bottom had the highest rate of infection (10.5%). Of the species tested, Cx. salinarius, Cx. erraticus, and Cx. pipiens/restuans were determined to be the most probable vectors of avian malaria the four sites.

In Australia, flavivirus infections of particular public health importance are DENV, KUNV, MVEV and JEV. Yellow fever is reported under Quarantinable diseases. These infections are nationally notifiable. No specific treatment is available for these diseases and care is largely supportive. A vaccine is available to prevent JEV infection50 but there are no vaccines currently for DENV, MVEV or KUNV infection. Infection with MVEV, KUNV or JEV is usually asymptomatic or produces a non-specific illness, but a small percentage of cases progress to encephalomyelitis of variable severity. Culex annulirostris is the major vector of MVEV, JEV and KUNV. DENV has 4 serotypes, each containing numerous genotypes. The serotypes isolated from returning travellers (and thus involved in local outbreaks) vary by year and geographical region. Infection with 1 serotype probably confers lifelong immunity to that serotype,21 but subsequent infection with a different serotype is 1 factor thought to increase the risk of ...

Reisen said he was surprised and humbled to receive the award. "John Belkin was a world-class mosquito taxonomist who set the bar for standards for mosquito descriptions.". Reisen, who received the honor at the AMCAs recent conference in Detroit, is the second UC Davis-affiliated entomologist to receive the award. Tom Zavortink, research associate with the Bohart Museum of Entomology at UC Davis and a retired professor of biology at the University of San Francisco, won the award in 1984.. Past recipients hail from England, Australia, Argentina, Brazil, Japan and Panama, as well as the United States (California, Florida, Utah, Illinois, Maryland, Pennsylvania and Washington D.C.) Reisen works in CVECs Arbovirus Research Program and serves as an adjunct professor with the Department of Pathology, Microbiology and Immunology at the UC Davis School of Veterinary Medicine. He currently focuses his research on Culex mosquitoes and their ability to transmit arboviruses, including West Nile virus. ...

Japanese encephalitis (JE) is an infectious disease that is caused by a virus transmitted by mosquitoes. Domestic and feral pigs, some species of birds, and humans are all involved in the transmission cycle of this very serious zoonosis. JE is endemic in some areas of Asia, where the major vector identified is Culex tritaeniorhynchus. Even though this specific mosquito is not present in US, all vectors competent for West Nile virus are potentially competent for JEV too, posing a serious threat for the US. Modeling JE presents major challenges, as all vector-borne zoonoses. Due to the complexities of multiple populations involved, the direct use of a network approach, similar to the one used by our group to model RVF [1], will lead to a large set of equations with many parameters to be estimated. To overcome this problem, the PI proposes to explore novel modeling approaches based on interconnected networks [2]. Interconnected networks are an abstract representation where two or more simple ...
Sinaloa has 180 cases of dengue - The Mazatlán PostSinaloa has 180 cases of dengue - The Mazatlán Post
The official explained that this year there has been no death due to dengue.. It works to close 2019 without deaths for this disease that can be prevented.. In recent days mosquitoes have proliferated in several parts of the city after the rains, but many are of the culex species, which are only a nuisance, the one that is at risk is Aedes aegypti.. To attack the vector of dengue, zika, and chikungunya, Vector and Zoonosis personnel travel through the homes of the riskiest areas and there are intensified actions for the elimination of hatcheries and the application of abbe. Where cases or suspects are recorded, it is fumigated to attack the adult mosquito. Source: el debate. The Mazatlan Post. ...

Insecticide resistance to organophosphates and carbamates can be the result of changes in acetylcholinesterase activity conferred by the ACE-1 mutation. Detection of this altered target site mutation is important in guiding informed decisions for resistance management. In this study we compared a competitive enzyme assay with a polymerase chain reaction assay utilizing a restriction enzyme. Both assays detected the ACE-1 mutation in Culex quinquefasciatus and agreement was 100%. The costs and benefits of each assay are presented ...
