“…In our previous work we found that Ae. albopictus possessed greater energy reserve accumulation in vegetational zones that they frequently were collected or found resting (Samson et al 2013). Because mosquitoes may rest and sugar feed within the same vegetation, seeking out a sugar meal presented in a bait station may have less of an impact in sub-tropical environments where sugar meals are readily available.…”

The purpose of this study was to test the efficacy of bait stations and foliar applications containing attractive toxic sugar baits (ATSB) and eugenol to control Aedes albopictus. At the same time the potential impact of these control methods was evaluated on non-target organisms. The study was conducted at five tire sites in St. Augustine, Florida. Aedes albopictus populations were significantly reduced with ATSB-eugenol applications applied directly to non-flowering vegetation and as bait stations compared with non-attractive sugar baits and control. The application of ATSB made to non-flowering vegetation resulted in more significant reductions of mosquito populations compared to the application of ATSB presented in a bait station. Over 5.5% of the non-targets were stained in the flowering vegetation application site. However, when the attractive sugar bait application was made to non-flowering vegetation or presented in bait stations the impact on non-target insects was very low for all non-target orders as only 0.6% of the individual insects were stained with the dye from the sugar solutions, respectively. There were no significant differences between the staining of mosquitoes collected in flowering vegetation (206/1000) or non-flowering vegetation (242/1000) sites during the non-target evaluation. Our field studies support the use of eugenol as an active ingredient for controlling the dengue vector Ae. albopictus when used as an ATSB toxin and demonstrates potential use in sub-tropical and tropical environments for dengue control.

“…Sugar feeding patterns of field captured Ae. albopictus mosquitoes have only been reported from three other locations: Israel, Italy, and Florida [16, 23, 32]. Our study reports Asian tiger mosquito sugar feeding patterns for the first time from the northern edge of its invasion in the Eastern USA.…”

“…albopictus , we know surprisingly little about its sugar feeding patterns in nature. Only four field studies have been conducted to date across vastly different habitats [16, 23, 32, 33]. Two studies indicated that season, habitat, and sugar availability might be important, as well as temperature and humidity [16, 23].…”

“…In Florida, where the only other US study was conducted, Ae. albopictus fructose concentration did not vary significantly with plant species utilized as resting habitat; unfortunately, no analyses were conducted to determine the proportion sugar fed [32]. Another limitation of these studies was the lack of established baseline fructose levels, leading to the potential misidentification of larval nutrients as adult sugar meals.…”

8 Background 9 Sugar feeding is an important behavior which may determine vector potential of mosquitoes.10 Sugar meals can reduce blood feeding frequency, enhance survival, and decrease fecundity, as 11 well as provide energetic reserves to fuel energy intensive behaviors such as mating and host 12 seeking. Sugar feeding behavior also can be harnessed for vector control (e.g. attractive toxic 13 sugar baits). Few studies have addressed sugar feeding of Aedes albopictus, a vector of 14 arboviruses of public health importance, including dengue and Zika viruses. To address this 15 knowledge gap, we assessed sugar feeding patterns of Ae. albopictus for the first time in its 16 invasive northeastern USA range. 1718 Methodology/ Principal Findings 19 Using the cold anthrone fructose assay with robust sample sizes, we demonstrated that a large 20 percentage of both male (49.6%) and female (41.8%) Ae. albopictus fed on plant or homopteran 21 derived sugar sources within 24 hrs of capture. Our results suggest that sugar feeding behavior 22 increases when environmental conditions are dry and may vary by behavioral status (host 23 seeking vs. resting). Furthermore, mosquitoes collected on properties with flowers (>3 blooms) 2 24 had higher fructose concentrations compared to those collected from properties with few to no 25 flowers (0-3). 2627 Conclusions/Significance 28 Our results provide the first evidence of Ae. albopictus sugar feeding behavior in the 29 Northeastern US and reveal relatively high rates of sugar feeding. These results suggest the 30 potential success for regional deployment of toxic sugar baits. In addition, we demonstrate the 31 impact of several environmental and mosquito parameters (environmental dryness, presence of 32 flowers, host seeking status, and sex) on sugar feeding. Placing sugar feeding behavior in the 33 context of these environmental and mosquito parameters provides further insight into 34 spatiotemporal dynamics of feeding behavior for Ae. albopictus, and in turn, provides 35 information for evidence-based control decisions. 37 Introduction 38Ae. albopictus is a vector of numerous pathogens, including dengue, Chikungunya and 39 Zika viruses as well as dog heartworm parasites [1, 2]. It is rapidly expanding its global range 40 and is pushing northward in the USA, enabled by local adaptation and winter egg diapause [3, 4].41 This highly adaptable mosquito can survive in drastically varied ecosystems, ranging from 42 tropical to temperate climates, making it one of the most successful invasive species globally [5].43 Understanding this mosquito's feeding behavior and ecology across its invasive range is essential 44 for understanding risk and devising control methods. 45Sugar feeding is an important mosquito behavior with implications for disease 46 transmission and control [6]. It can impact mosquito life history through a number of 3 47 mechanisms and can vary between mosquito species [7]. For females, there may be trade-offs in 48 transmission potential between blood and sugar feeding ...

27 Background 28 Three arthorpod-borne viruses (arboviruses) causing human disease have been the focus 29 of a large number of studies in the Americas since 2013 due to their global spread and 30 epidemiological impacts: Zika, dengue, and chikungunya viruses. A large proportion of 31 infections by these viruses are asymptomatic. However, all three viruses are associated with 32 moderate to severe health consequences in a small proportion of cases. Two mosquito species, 33 Aedes aegypti and Aedes albopictus, are among the world's most prominent arboviral vectors, 34 and are known primary vectors for all three viruses in the Americas. 35 Objectives 2 36 This review summarizes the state of the entomological literature surrounding the biology 37 and ecology of vectors of Zika, dengue and chikungunya viruses and factors affecting virus 38 transmission. The rationale of the review was to elucidate consensus and discord between 39 studies, and guide future research based on identified knowledge gaps. 40 Results 41 A total of 196 studies were included in the scoping review after initial screening and 42 subsequent exclusion of out-of-scope studies, secondary data publications, duplicate records, and 43 studies unavailable in English language. 44 Key findings 45 Temperature and humidity have the strongest impact on mosquito distribution and 46 dynamics, development of immatures and arborviral infection rates. Low socioeconomic status 47 and related factors, including poor infrastructure, inconsistent access to water, and high 48 household resident density, have been consistently associated with arbovirus vector occurrence. 49 Effects of interspecific competition on arboviral vector species is currently poorly understood. 50 Vector competence for Zika virus is well established for Ae. aegypti and Ae. albopictus. 51 Information on Zika virus vector transmission dynamics is sparse in contrast to the wealth of 52 research available for dengue and chikungunya viruses. 53 Conclusions 54Based on the internationally recognized urgency of Zika virus infection as a public health 55 concern, further research on arbovirus vectors and transmission dynamics is of pressing need. 56 57
