ecology of vector Mosquitoes in sri lanka suggestions for future Mosquito Control in rice ecosystems
Southeast Asian Journal of Tropical Medicine and Public Health, 2007Co-Authors: Junko Yasuoka, Richard LevinsAbstract:Mosquito-borne diseases are a major public health threat in Asia. To explore effective Mosquito Control strategies in rice ecosystems from the ecological point of view, we carried out ecological analyses of vector Mosquitoes in Sri Lanka. During the 18-month study period, 14 Anopheles, 11 Culex, 5 Aedes, 2 Mansonia, and 1 Armigeres species were collected, most of which are disease vectors for malaria, filariasis, Japanese encephalitis, or dengue in Sri Lanka and elsewhere in Asia. The density and occurrence of Anopheles and Culex species were the highest in seepage pools and paddy fields, where the majority of niche overlaps between larval Mosquito and aquatic insect species were observed. All 7 aquatic insect species, which are larval Mosquito predators, overlapped their niche with both Anopheles and Culex larvae. This suggests that conserving these aquatic insect species could be effective in Controlling Mosquito vectors in the study site. Correlations between several climatic factors and Mosquito density were also analyzed, and weather conditions, including higher temperature, lower relative humidity, and higher wind velocity, were found to affect Mosquito oviposition, propagation, and survival. These findings deepen our understanding of Mosquito ecology and will strengthen future Mosquito Control strategies in rice ecosystems in Asia.

On the dynamics of a deterministic and stochastic model for Mosquito Control
Applied Mathematics Letters, 2007Co-Authors: M. Predescu, G. Sirbu, Richard Levins, Tamara Awerbuch-friedlanderAbstract:Abstract In this work, we analyze a system of nonlinear difference equations describing community intervention in Mosquito Control. More specifically, we extend the model given in [M. Predescu, R. Levins, T. Awerbuch, Analysis of a nonlinear system for community intervention in Mosquito Control, Discrete Contin. Dyn. Syst. Ser. B 6 (3) (2006) 605–622] to allow for consciousness to be created in an ongoing way by educational efforts that are independent of the presence of Mosquito breeding sites. In order to quantify the effect of random external events, such as weather or public concerns, we consider a stochastic version of the model. Numerical simulations show that the stochastic model is consistent with the deterministic one.

Impact of education on knowledge, agricultural practices, and community actions for Mosquito Control and Mosquito-borne disease prevention in rice ecosystems in Sri Lanka.
The American journal of tropical medicine and hygiene, 2006Co-Authors: Junko Yasuoka, Thomas W. Mangione, Andrew Spielman, Richard LevinsAbstract:Mosquito-borne diseases are a major public health threat in Sri Lanka. A 20-week pilot education program to improve community knowledge and Mosquito Control with participatory and non-chemical approaches was developed, implemented, and evaluated using pre-educational and post-educational surveys in two intervention and two comparison villages. Correlates of baseline knowledge were sex, number of family members, ratio of family members with malaria history, school education level, and availability of electricity at the residence. Participation in the educational program led to improved knowledge of Mosquito ecology and disease epidemiology, changes in agricultural practices, and an increase in environmentally sound measures for Mosquito Control and disease prevention. The variety of actions at the post-educational stage were determined by improved knowledge, but not by sociodemographic characteristics. Such community-based educational interventions are effective in increasing understanding and active involvement in Mosquito Control and disease prevention in rice ecosystems regardless of sociodemographic characteristics.

Mosquito Control and Coastal Development: How they Have Coexisted and Matured in Florida and Australia
Journal of the American Mosquito Control Association, 2019Co-Authors: Douglas B. Carlson, Patricia Ellen Dale, Nina Kurucz, Patrick G. Dwyer, Jon Knight, Peter I Whelan, D. Diane RichardsAbstract:The aims of this review were to compare planning for both Mosquito Control and land use in east-central Florida, USA, and in New South Wales, Queensland, and the Northern Territory, Australia. Saltwater Mosquito production in mangroves and salt marsh is the predominant Mosquito Control concern in all the areas. Urban encroachment towards saltwater Mosquito habitats is a problem in both Florida and Australia. In east-central Florida and the Northern Territory, Mosquito Control is supported by comprehensive source reduction programs, whereas in Queensland and New South Wales, larviciding is the main method of Control. The long-term Control by source reduction programs reduces vulnerability to Mosquito issues as population encroaches towards wetlands, whereas larviciding programs have to respond repeatedly as problems arise. Problems from urban encroachment are exacerbated if Mosquito Control and land-use planning are not integrated. Further, urban planning that is not informed by Mosquito management can lead to increased Mosquito problems by inadvertent design or allowing residential development close to Mosquito habitats. This increases the need for Mosquito Control and related resourcing. At the regional level of governance, Florida and the Northern Territory generally have greater integration between planning for development and Mosquito Control than at the local government level in New South Wales and Queensland, where there is a lack of integration between Mosquito agencies and planners. It is concluded that coordination of planning and Mosquito Control is more effective at higher government levels than at local levels, which have less connectivity between management areas and/or insufficient resources. The lesson is that collaboration can assist in avoiding or resolving conflicts.

Does Mosquito Control have an effect on Mosquito-borne disease? The case of Ross River virus disease and Mosquito management in Queensland, Australia.
Journal of the American Mosquito Control Association, 2011Co-Authors: Deanna Majella Tomerini, Patricia Ellen Dale, Neil SipeAbstract:We examined the relationship between types of Mosquito Control programs and the Mosquito-borne Ross River virus (RRV) disease in Queensland, Australia. Mosquito Control information was collected through a survey of the responsible agencies (local governments), and RRV disease notification data were provided by the Queensland state health authority. The study developed a typology of Mosquito Control programs, based on the approaches used. Based on the analysis of data on RRV disease rates between Mosquito Control types within 4 climatic regions, each region had different combinations of Mosquito Control strategies in their programs; there were also general similarities in the relationship between program types and RRV rates between the regions. The long-term RRV disease rates were lower in areas where the Mosquito Control program included pre-emptive (rather than reactive) surveillance based on an extensive (rather than incomplete) knowledge of Mosquito habitats, and where treatment of both saltwater and freshwater habitats (compared to only saltwater habitats, in coastal areas) occurred. The data indicate that Mosquito Control is an effective public health intervention to reduce Mosquito-borne disease; hence, climate change adaptation strategies should ensure that adequate resources are available for effective vector Control so as to manage the risk of Mosquito-borne diseases.

Does Mosquito Control reduce Mosquito-borne disease? A Ross River virus example from Australia.
2009Co-Authors: Deanna Majella Tomerini, Patricia Ellen Dale, Neil SipeAbstract:This paper reports the results of a study to assess the effect of Mosquito Control strategies on the incidence of Ross River virus, a polyarthritic disease transmitted by Mosquitoes. Although several Mosquito species are implicated in its transmission, the major vectors are the salt marsh Mosquito Aedes vigilax (Skuse) and the freshwater species Culex annulirostris Skuse. The four areas reported here are in eastern Queensland, selected by Koeppen climate class to minimise the effects of climatic variation. The disease data were obtained from the Queensland State Health department and Mosquito Control information was collected from Local Government Authorities by survey, using a structured questionnaire. Mosquito Control practices were categorized according to their surveillance protocols and treatment regimes, and Analysis of Variance was used to compare the Mosquito Control types to long-term disease incidence. The results showed that long-term RRV disease incidence was lowest in areas with programs that included routine and pre-emptive surveillance combined with extensive treatment of both saltwater and freshwater Mosquito habitat. It is concluded that integrated programs that include surveillance and treat all major habitats of the vectors can have a significant effect on the incidence on Mosquito borne disease, in this case RRV.

Four Degrees of Latitude: Mosquito Control on the “Right” Coasts of Australia and Florida, USA
Journal of the American Mosquito Control Association, 2008Co-Authors: Patricia Ellen Dale, Douglas B. Carlson, Clive S. EastonAbstract:This study compares Mosquito Control within similar environments between 26 and 30 degrees of latitude on the east central coasts of Florida and of Australia. It describes and compares the relevant Mosquito-producing environments, the development of Mosquito Control, legislative framework, funding arrangements, and organizational differences between the areas, including the international interactions that have facilitated good practices. The article identifies some strengths and weaknesses of the programs in each area. Significant strengths include some aspects of funding and administration; collaborations with other organizations; the roles of national and state organizations, including research agencies; and commitment of individuals. Potential weaknesses in programs that are part of larger organizations include their relatively low position in the organizational hierarchy and the need to compete for resources. Programs that are independent districts may lack opportunity to interact with other land management units. Other weaknesses include the relatively high turnover of staff in state environmental resource agencies and the potential loss of institutional memory when long-term Mosquito Control staff members leave. The case comparison highlights similarities in product use at the individual program level (Indian River Mosquito Control District and Gold Coast Pest Management Unit) and differences in practices including aerial adulticiding being used in Florida but not in Australia.

The endangered Illidge's ant blue butterfly (Acrodipsas illidgei) from an intertidal habitat managed for Mosquito Control.
Journal of the American Mosquito Control Association, 2004Co-Authors: Mark Juergen Breitfuss, Patricia Ellen DaleAbstract:Acrodipsas illidgei is an endangered butterfly inhabiting mangrove forests in southeastern Queensland, Australia. Concern over the effects of Mosquito Control activities prompted a broad-scale survey for the species at Coomera Island, in southeastern Queensland. The butterfly was recorded on the edge of an old-growth mangrove forest in close proximity to Mosquito Control runnels. Other forms of Mosquito Control at Coomera Island are unlikely to impact on the species because of the mode of action of larvicides used and the fact larvae occur within ant colonies formed in hollow stems and branches of mangrove trees. Further studies are required to more fully understand the relationships between Mosquito Control activities and the population dynamics of endangered species such as A. illidgei.

Environmental and socioeconomic effects of Mosquito Control in Europe using the biocide Bacillus thuringiensis subsp. israelensis (Bti)
The Science of the total environment, 2020Co-Authors: Carsten A. Brühl, Laurence Després, Oliver Frör, Chandrashekhar D. Patil, Brigitte Poulin, Guillaume Tetreau, Stefanie AllgeierAbstract:Bacillus thuringiensis subsp. israelensis (Bti) has been used in Mosquito Control programs to reduce nuisance in Europe for decades and is generally considered an environmentally-safe, effective and target-specific biocide. However, the use of Bti is not uncontroversial. Target Mosquitoes and affected midges represent an important food source for many aquatic and terrestrial predators and reduction of their populations is likely to result in food-web effects at higher trophic levels. In the context of global biodiversity loss, this appears particularly critical since treated wetlands are often representing conservation areas. In this review, we address the current large-scale use of Bti for Mosquito nuisance Control in Europe, provide a description of its regulation followed by an overview of the available evidence on the parameters that are essential to evaluate Bti use in Mosquito Control. Bti accumulation and toxin persistence could result in a chronic expose of Mosquito populations ultimately affecting their susceptibility, although observed increase in resistance to Bti in Mosquito populations is low due to the four toxins involved. A careful independent monitoring of Mosquito susceptibility, using sensitive bioassays, is mandatory to detect resistance development timely. Direct Bti effects were documented for non-target chironomids and other invertebrate groups and are discussed for amphibians. Field studies revealed contrasting results on possible impacts on chironomid abundances. Indirect, food-web effects were rarely studied in the environment. Depending on study design and duration, Bti effects on higher trophic levels were demonstrated or not. Further long-term field studies are needed, especially with observations of bird declines in Bti-treated wetland areas. Socio-economic relevance of Mosquito Control requires considering nuisance, vector-borne diseases and environmental effects jointly. Existing studies indicate that a majority of the population is concerned regarding potential environmental effects of Bti Mosquito Control and that they are willing to pay for alternative, more environment-friendly techniques.

Mosquito Control EMERGENCY PREPAREDNESS AND RESPONSE TO NATURAL DISASTERS.
Journal of the American Mosquito Control Association, 2020Co-Authors: C. Roxanne Connelly, Jeff N. BorchertAbstract:On February 9, 2019, the Bipartisan Budget Act of 2018 was signed into law and appropriated $200M in hurricane funding to the Centers for Disease Control and Prevention (CDC) for preparation, response, recovery, mitigation, and other expenses related to the consequences of Hurricanes Harvey, Irma, and Maria. The CDC then awarded, through CDC-RFA-TP18-1802 Cooperative Agreement for Emergency Response: Public Health Crisis Response notice of funding opportunity, $51,136,347 in extramural funding. Funding specific to vector-borne diseases, including intramural and extramural (partners and jurisdictions), was $37,628,235 to Florida, Georgia, Louisiana, Mississippi, Texas, Puerto Rico, and US Virgin Islands. State and territorial funding supported the implementation of conventional and novel Mosquito Control techniques, training for public health pest Control applicators, replacement of Mosquito surveillance and Control supplies utilized in the aftermath of the 2017 hurricanes, insecticide resistance testing and training, and source reduction. Additionally, the CDC hurricane funding supported this special issue of the Journal of the American Mosquito Control Association (JAMCA) focused on Mosquito Control response in the wake of natural disasters. We invited hurricane relief funding grantees, Mosquito Control programs, academics, manufacturers, product distributors, and applicators to submit response plans or descriptive articles related to their experience with Mosquito Control after natural disasters. The objective of this special issue of JAMCA is to provide a comprehensive volume that includes resources to help guide Mosquito Control in areas affected by natural disasters. The shared experiences should serve to assist others involved in Mosquito Control in planning for and responding to natural disasters.

Mosquito Control Activities during Local Transmission of Zika Virus, Miami-Dade County, Florida, USA, 2016.
Emerging infectious diseases, 2020Co-Authors: Janet C. Mcallister, C. Roxanne Connelly, Mario C. Porcelli, Johana Medina, Mark J. Delorey, Marvin S. Godsey, Nicholas A. Panella, Nicole Dzuris, Karen A. Boegler, Joan L. KenneyAbstract:In 2016, four clusters of local Mosquitoborne Zika virus transmission were identified in Miami-Dade County, Florida, USA, generating "red zones" (areas into which pregnant women were advised against traveling). The Miami-Dade County Mosquito Control Division initiated intensive Control activities, including property inspections, community education, and handheld sprayer applications of larvicides and adulticides. For the first time, the Mosquito Control Division used a combination of areawide ultralow-volume adulticide and low-volume larvicide spraying to effectively Control Aedes aegypti Mosquitoes, the primary Zika virus vector within the county. The number of Mosquitoes rapidly decreased, and Zika virus transmission was interrupted within the red zones immediately after the combination of adulticide and larvicide spraying.

North American Wetlands and Mosquito Control
International journal of environmental research and public health, 2012Co-Authors: Jorge R. Rey, William E. Walton, Roger J. Wolfe, C. Roxanne Connelly, Sheila M. O'connell, Joe Berg, Gabrielle E. Sakolsky-hoopes, Aimlee D. LadermanAbstract:Wetlands are valuable habitats that provide important social, economic, and ecological services such as flood Control, water quality improvement, carbon sequestration, pollutant removal, and primary/secondary production export to terrestrial and aquatic food chains. There is disagreement about the need for Mosquito Control in wetlands and about the techniques utilized for Mosquito abatement and their impacts upon wetlands ecosystems. Mosquito Control in wetlands is a complex issue influenced by numerous factors, including many hard to quantify elements such as human perceptions, cultural predispositions, and political climate. In spite of considerable progress during the last decades, habitat protection and environmentally sound habitat management still remain inextricably tied to politics and economics. Furthermore, the connections are often complex, and occur at several levels, ranging from local businesses and politicians, to national governments and multinational institutions. Education is the key to lasting wetlands conservation. Integrated Mosquito abatement strategies incorporate many approaches and practicable options, as described herein, and need to be well-defined, effective, and ecologically and economically sound for the wetland type and for the Mosquito species of concern. The approach will certainly differ in response to disease outbreaks caused by Mosquito-vectored pathogens versus quality of life issues caused by nuisance-biting Mosquitoes. In this contribution, we provide an overview of the ecological setting and context for Mosquito Control in wetlands, present pertinent information on wetlands Mosquitoes, review the Mosquito abatement options available for current wetlands managers and Mosquito Control professionals, and outline some necessary considerations when devising Mosquito Control strategies. Although the emphasis is on North American wetlands, most of the material is applicable to wetlands everywhere.

Countering a bioterrorist introduction of pathogen-infected Mosquitoes through Mosquito Control.
Journal of the American Mosquito Control Association, 2011Co-Authors: Walter J. Tabachnick, C. Roxanne Connelly, William R. Harvey, James J. Becnel, Gary G. Clark, Jonathan F. Day, Paul J. Linser, Kenneth J. LinthicumAbstract:The release of infected Mosquitoes or other arthropods by bioterrorists, i.e., arboterrorism, to cause disease and terror is a threat to the USA. A workshop to assess Mosquito Control response capabilities to mount rapid and effective responses to eliminate an arboterrorism attack provided recommendations to improve capabilities in the USA. It is essential that Mosquito Control professionals receive training in possible responses, and it is recommended that a Council for Emergency Mosquito Control be established in each state to coordinate training, state resources, and actions for use throughout the state.
