Background: Historically, the incidence of malaria in the Hainan Province, China has been high. However, since 2001 the malaria incidence in Hainan has decreased due to large-scale, public educational, promotional campaigns and the adoption of preventative measures against malaria following the fast growth of socio-economic development. The present study analysed the correlation between prevention measures and social economic development on the incidence of malaria in Hainan from 2001 to 2013. Methods: The data of malaria preventative measures and socio-economic development were collected from various cities and counties in Hainan Province from 2001 to 2013 and analysed by the grey correlation analysis system. Results: Seasonal preventive medication and local fiscal revenue increases are significantly related to the reduction of malaria incidence from 2001 to 2013 (R1 = 0.751677; R5 = 0.764795). Conclusion: Malaria prevention and control measures and local economic development in Hainan decreased malaria incidence from 2001 to 2013. © 2014 Wang et al.; licensee BioMed Central Ltd.

The aim of this study was to further investigate the use of attractive sugar baits as an effective, inexpensive, and environmentally friendly tool for integrated mosquito management programs. Mosquitoes were offered dyed sugar bait in wells and cisterns in an urban tourist area in St. Augustine, FL. Exit traps were constructed to cover the well and cistern openings so the number of resting and emerging mosquitoes stained by feeding on the sugar bait could be monitored. Four mosquito species were collected from these structures: Aedes albopictus (Skuse), Anopheles crucians (Wiedemann), Culex quinquefasciatus Say, and Toxorhynchites rutilus rutilus (Coquillett). Overall, 90% (1482/1644) of the mosquitoes trapped were stained. In general, the number of mosquitoes stained was significantly greater in wells (P<. 0.0001) and cisterns (P<. 0.0001) than the numbers that were not stained by the colored bait. Based on the number of mosquitoes stained, we would have expected considerable mosquito mortality had the sugar bait contained an oral toxin. The results of this study support the concept of using attractive toxic sugar baits as an effective tool for integrated mosquito management. © 2012.

The international trade of lucky bamboo (Dracaena sanderiana [Asparagaceae]) is responsible for certain introductions of the exotic species Aedes albopictus (Skuse) in California and the Netherlands. Understanding the association of this species with lucky bamboo and other ornamental plants is important from a public health standpoint. The aim of this study was to investigate the importance of indoor ornamental plants as sugar sources for adult A. albopictus. If exposed to D. sanderiana, bromeliad (Guzmania spp. hybrid [Bromeliaceae]), Moses-in-the-cradle (Rhoeo spathacea [Commelinaceae]), 10 % sucrose solution, and a negative water control as the only nutrient source, adult female A. albopictus mean survival time was 12, 7, 6, 15, and 4 days, respectively. Mean survival times for adult males were not significantly different (P > 0.05) from the females and were 10, 7, 6, 14, and 3 days, respectively. Combined male and female survival times were not significantly different on lucky bamboo compared to survival times on a 10 % sucrose control. Based on our findings, A. albopictus can readily survive long enough to complete a gonotrophic cycle and potentially complete the extrinsic incubation period for many arboviruses when only provided access to lucky bamboo plants or possibly other common ornamentals. Vector control professionals should be aware of potential in-home infestations and public health concerns associated with mosquito breeding and plant tissue feeding on ornamental plants. © 2013 Springer-Verlag Berlin Heidelberg.

The sugar feeding of Aedes albopictus was studied. In outdoor cages they fed avidly on carob (Ceratonia siliqua L., Caesalpiniaceae) seed pods soiled with sugary exudates. Feeding was either from the surface or by piercing the tissue which is indicated by the presence of plant tissue residues in the gut. More than 90% were sugar positive and about a third had plant tissue residues in the gut after overnight exposure. Similar exposure to clean undamaged seed pods resulted in about two thirds sugar positive mosquitoes and all of these had plant-tissue residues in the gut.In an irrigated, field site, with abundance of sugar sources in the summer 68% of the females and 75% of the males were sugar positive whereas, 1.2% of the females and no males had plant tissue in the gut. The proportion of sugar positive mosquitoes was similar in the autumn and plant tissue was not found in 150 females and 13 males. In the dry site in the summer 42% females and 33% males were sugar positive while 22% females and 33% males contained plant tissue. In the autumn 73% females and 80% males were sugar positive while 2% females and none of the males contained plant tissue. © 2010 Elsevier B.V.

Sugar is the main source of energy for the activities of mosquitoes; however, information on the vital sugar feeding of Aedes albopictus in the field is scanty and often anecdotal. Using glue traps and baits, we evaluated the attraction of Ae. albopictus to 28 different, potential sugar sources. Control traps were baited with either sugar-water solution or water alone, and since there was no significant difference between these controls, the water control was used as the standard for comparison. The total catch amounted to 1347 females and 1127 males. An attraction index (mean number of mosquitoes attracted to the baits/mean number of mosquitoes attracted to the control) was used to compare the relative attraction of the baits. The attraction index of significantly attractive baits ranged from 2.5 to 50.0 and the index of others ranged from 0.50 to 2.75. None of the baits were repellent. Significantly high attraction was observed for four of six ornamental flowers (Tamarix chinensis, Vitex agnus-castus, Polygonum baldchuanicum, Buddleja davidii), four of eleven wild flowers (Prosopis farcta, Ziziphus spina-christi, Polygonum equisetiforme, Ceratonia siliqua), the only tested seed pod when damaged and fermenting (C. siliqua), and all five of the tested fruits: Opuntia ficus indica (sabra), Ficus carica (fig), Punica granatum (pomegranate, damaged), Eriobotyra japonica (loquat), and Rubus sanctus (raspberry). Unlike damaged, fermenting carob seed pods and pomegranates, the fresh fruits were not attractive. Attraction to foliage soiled with honeydew excretion of three different aphid species was also not significant. The potential to use attractive sugar sources for mosquito control is discussed. © 2011 Elsevier B.V.

In this study, 27 CDC traps were modified with various attractive features and compared with a CDC trap with no light source or baits to evaluate the effects on attraction to Phlebotomus papatasi (Scopoli) north of the Dead Sea near Jericho. Attractive features included CO2, lights, colored trap bodies, heat, moisture, chemical lures and different combinations of the same. Traps were placed 20m apart and rotated from one trap location to the next after 24h trapping periods. The most significant attractive feature was CO2, which attracted more sand flies than any other feature evaluated. Ultraviolet light was the next most attractive feature, followed by incandescent light. When evaluated alone, black or white trap bodies, heat and moisture, all influenced trap catch but effects were greater when these attractive features were used together. The results of this study suggest that traps with CO2 and UV light could be used in batteries as control interventions if suitable CO2 sources become available. © 2014 Elsevier B.V.

Two permethrin formulations, AquaReslin® and AquaKontrol®, were applied by ultra-low volume truck-mounted sprayers on test plots under appropriate meteorological condition at Jacksonville, FL. The method of application was followed from the product label. The application rate for each formulation was 0.79 g permethrin per acre. AquaReslin and AquaKontrol demonstrated similar results against Anopheles quadrimaculatus; the former was superior to the latter used against Aedes aegypti, and Ae. albopictus. Teflon®-coated standard glass slides were used to collect the aerosol components. Volume median-diameter droplets per square centimeter varied with pesticides and distance from spray source, and the mortality of the 3 species at 18 h ranged from 61.3% to 91.7%. © 2011 by The American Mosquito Control Association, Inc.

DUET™ was evaluated against field-collected mosquito populations in St. John's County, FL, under laboratory and field conditions. Ten serial dilutions ranging from 22 to 2.2E-08 g/ml of the product were tested against Aedes albopictus, Ae. taeniorhynchus, Culex quinquefasciatus, and Psorophora columbiae. At 0.0022 μg/ml, 100 mortality was recorded for all species except for Cx. quinquefasciatus. The 50 lethal concentration value for Cx. quinquefasciatus was 0.0029 g/ml (CI 0.00069 to 0.013). At the lowest dilution (2.2E-08 μg/ml) evaluated, Ae. albopictus, Ae. taeniorhynchus, and Ps. columbiae showed >50 mortality. Ground ultralow-volume application of DUET resulted in overall average mortality of 87 of field-collected Cx. quinquefasciatus mosquitoes. There was a significant difference in mortality based on the distance of the caged mosquitoes (P < 0.05). However, mortality was >70 at the farthest distance from the application (106 m). © 2010 by The American Mosquito Control Association, Inc.

The OFF! Clip-on mosquito-repellent device was tested outdoors against Aedes aegypti (L.). A single treatment device was used against batches of caged adult, nonblood fed Ae. aegypti at multiple locations 0.3m from treatment center. Another set of cages was stationed 0.6m from treatment. A final set of cages was placed 0.9m away. Trials ran for durations of 5, 15, 30, and 60 min. Initial knockdown and mortality after 24 h was recorded. The devices had effective knockdown and mortality. This was not sustained at distances greater than 0.3m from the device. © The Authors 2016.

Seven commercial synthetic disinfectant and antibacterial soap products were evaluated as mosquito larvicides against Culex quinquefasciatus Say in the laboratory. Three aerosol disinfectant products, at 0.01% concentration resulted in 58-76% mortality of laboratory-reared fourth instar mosquito larvae at 24 h posttreatment. Four antibacterial soap products at 0.0001% concentration resulted in 88-100% larval mortality at 24 h posttreatment. The active ingredient of the antibacterial soap products, triclosan (0.1%) resulted in 74% larval mortality. One of the antibacterial soap products, Equate caused the highest mosquito larval mortality in the laboratory. Equate antibacterial soap at the application rate of 0.000053 ppm resulted in 90% mortality of the introduced fourth instar larvae of Cx. quinquesfasicatus in the outdoor pools. In laboratory and field bioassays, the antibacterial soap resulted in significant larval mosquito mortality. © 2013 Entomological Society of America.
