“…In a study by [55] in Manaus, a high density of A. albopictus was observed in both the central and peripheral regions of the city, where it occurred in areas of urban and periurban forest with anthropogenic alterations and a large number of artificial containers, corroborating the present results. More recently, [33] also observed predominance of A.…”

“…In general, the efficiency of the traps may have been enhanced by the presence of the grass infusion, as it has proven efficacy in attracting Aedes spp. compared with the use of only distilled or piped water [32,33,38,58]. The Vectobac WG ® (B. thuringiensis israelensis)…”

“…biolarvicide used in the experiment as well as other Bti-based products, in conjunction with traps, also can be an important aid for monitoring in view of the proven efficacy of Bti in control of the larvae of Aedes spp. Thus, if the larvae hatch from the eggs laid by the females in the reeds, they will not develop into adult form [32,33]. In addition, the effect of Bti comes from four major synergistic toxins (Cry4Aa, Cry4Ba, CryllAa and CytlAa), which may reduce the likelihood of selection of resistant target organisms [41,[59][60][61][62], besides not cause damage to other organisms (except Chironomidae and Simuliidae)) due to their high specificity for mosquitoes [40,63].…”

“…This tool is capable of promoting both monitoring of vectors as well as allowing the removal of eggs from the environment, providing indices of indirect mosquito abundance and allowing verification of their spatial and temporal distribution through the number of eggs collected [30][31][32][33][34]. In addition, they have been recommended by the Brazilian Ministry of Health to assist in the surveillance and control of Aedes spp.…”

The control of arboviruses carried by Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse) can be performed with tools that monitor and reduce the circulation of these vectors. Therefore, the efficiency of four types of traps in capturing A. aegypti and A. albopictus eggs and adults, with the biological product Vectobac WG®, was evaluated in the field. For this, 20 traps were installed in two locations, which were in the South (Londrina, Paraná) and North (Manaus, Amazonas) Regions of Brazil, from March to April 2017 and January to February 2018, respectively. The UELtrap-E and UELtrap-EA traps captured A. aegypti and A. albopictus eggs: 1703/1866 eggs in Londrina, and 10268/2149 eggs in Manaus, respectively, and presented high ovitraps positivity index (OPI) values (averages: 100%/100% in Londrina, and 100%/96% in Manaus, respectively); and high egg density index (EDI) values (averages: 68/75 in Londrina, and 411/89 in Manaus, respectively), so they had statistically superior efficiency to that of the CRtrap-E and CRtrap-EA traps in both regions, that captured less eggs and adults: 96/69 eggs in Londrina, and 1091/510 eggs in Manaus, respectively. Also presented lower OPI values (averages: 28%/4% in Londrina, and 88%/60% in Manaus, respectively); and lower EDI values (averages: 10.5/9 in Londrina, and 47/30 in Manaus, respectively). The capture ratios of Aedes adults in the UELtrap-EA and CRtrap-EA traps in Londrina and Manaus were 53.3%/29.5% and 0%/9.8%, respectively. UELtrap-E and UELtrap-EA can be adopted as efficient tools for Aedes monitoring due to their high sensitivity, low cost and ease of use.Author summaryAedes aegypti and Aedes albopictus are species of mosquitoes responsible for the transmission of several arboviruses that cause infections worldwide. However, there are still no effective and safe vaccines or medications to prevent or treat arboviruses transmitted by these vectors, except for yellow fever. Moreover, current methodologies for monitoring and controlling A. aegypti and A. albopictus are not fully effective, as evidenced by the increasing cases of the arbovirus transmitted by these mosquitoes or have incompatible costs with the socioeconomic conditions of a large number of people. Thus, the traps tested in this study can be used as more effective and economical tools for monitoring and controlling A. aegypti and A. albopictus, since they are made with low cost material and they showed high efficiency in the capture of eggs, evidenced by the high values of ovitraps positive index and eggs density index, besides that one of the models captured Aedes spp. adults in both regions where they were tested. Therefore, the traps have potential for reducing Aedes spp. eggs and adults in the environment and sensibility for determining the local infestation index, which can be reconciled with official government strategies for more accurate vector monitoring and control actions.

Abstract. Ratnasari A, Jabal AR, Rahma N, Rahmi SN, Karmila M, Wahid I, 2020. The ecology of Aedes aegypti and Aedes albopictus larvae habitat in coastal areas of South Sulawesi, Indonesia. Biodiversitas 21: 4648-4654. Aedes aegypti and Aedes albopictus are arbovirus vectors that can adapt to various environmental conditions. This study aimed to analyze the spatial distribution, habitat characteristics, and the correlation between the number of Ae. aegypti and Ae. albopictus larvae with physical factors. The larvae were collected from seven sampling locations along the coast of South Sulawesi at a distance of 100 m, 500 m, 1 km, and 2 km from the coastline. The collected samples and their water habitat were examined in the Entomology Laboratory of the Faculty of Medicine, Hasanuddin University, South Sulawesi, Indonesia. The number of larvae was counted (3182 larvae of both kinds), and the pH and salinity of the water were measured. Data analysis was performed with IBM SPSS version 24 and spatial distribution of larvae was mapped with ArcGIS version 10.5. We found that the highest number of Ae. aegypti was at a distance of 100 m from the coastline (73.34%), while Ae. albopictus was at 500 m (34.14%). Most of the mosquitos laid their eggs on discarded boats as observed in the Kurri Caddi coast (31.2%). The observed ranges of pH, salinity, and temperature of larvae habitat were 5.5-6.4, 5-2 ppt, and 28-31°C, respectively. The total number of larvae had a significant correlation p<0.05 with the physical factors, i.e., distance from the coastline, water pH, temperature, and kind of water storages (containers). This study showed that physical factors in the coastal area significantly influenced the habitat characteristics and the abundance of Ae. aegypti and Ae. albopictus larvae.
