Influence of physical chemical water parameters on abundance and presence of the arbovirus vector Aedes Albopictus (Dipteria: Culicidae) in Larval habitats of forest fragments

Nymphaeion alliance vegetation is dominant floating-leaved vegetation in the Danube–Tisza–Danube hydrosystem in northwestern Serbia and comprises Nymphaeetum albae, Nymphaeetum albo-luteae, Nymphoidetum peltatae and Trapetum natantis associations. Comparative analysis of physical-chemical water parameters on localities where these – in most parts of Europe endangered and vulnerable stands – develop showed that most phytocenoses are associated with specific habitat conditions. Of the analyzed water properties, the factors that cause Nymphaeion alliance phytocenoses differentiation are primarily pH, alkalinity and COD-MnO4. Formation of the Nymphaeetum albae stands is significantly associated with the highest values of pH, COD-MnO4 and alkalinity, and the lowest nitrate, nitrite, dissolved and the total phosphorus content values, in comparison to the other studied associations. Nymphoidetum peltatae stands develop in waters characterized by the lowest pH and COD-MnO4, low alkalinity, and the highest nitrate and nitrite values in relation to the other analyzed phytocenoses. Trapetum natantis stands, on the other hand, prefer the warmer sections of the canal network, neutral pH, and the highest values of BOD5, dissolved and total phosphorus. Habitat conditions in which Nymphaeetum albo-luteae stands develop are of the widest range in comparison to other investigated phytocenoses.

The objective of the present study was to determine the diversity of phytoplankton and itsrelationship with physical-chemical water parameters of Gampong Pulot Lagoon, Leupungsubdistrict, Aceh Besar. The collecting of phytoplankton and water quality were conducted inDecember 2014. According to field assessment, there were six stations to represent the study site.We recorded 25 species of phytoplankton from class Bacillariophyceae, Dinophyceae andCyanophyceae. The abundance of Bacillariophyceae was 1202.02 ind / L classified as moderate,while Dinophyceae and Cyanophyceae were 621.13 ind / L and 208.49 ind / L, respectively,classified as low abundance. Bacillariophyceae was dominated by Rhizosolenia sp. with 26% ofcomposition. The diversity index has varied from 1,88 to 2,63 indicated as moderate value. Basedon Principal Component Analysis (PCA) showed that the physical-chemical water parameters relatedto the abundance of phytoplankton in Gampong Pulot Lagoon.Keywords: phytoplankton, lagoon, diversity, leupung

Virus Vectors

The primary dengue virus vectors, Aedes aegypti and Aedes albopictus, are primarily daytime biting mosquitoes. The risk of infection is suspected to be considerable in urban parks due to visitor traffic. Despite the importance of vector control for reducing dengue transmission, little information is available on vector populations in urban parks. The present study characterized mosquito habitats and estimated vector densities in the major urban parks in Ho Chi Minh City, Vietnam and compared them with those in adjacent residential areas. The prevalences of habitats where Aedes larvae were found were 43% and 9% for the parks and residential areas, respectively. The difference was statistically significant (prevalence ratio [PR]: 5.00, 95% CI: 3.85–6.49). The prevalences of positive larval habitats were significantly greater in the parks for both species than the residential areas (PR: 1.52, 95% CI: 1.04–2.22 for A. aegypti, PR: 10.10, 95% CI: 7.23–14.12 for A. albopictus). Larvae of both species were positively associated with discarded containers and planters. Aedes albopictus larvae were negatively associated with indoor habitats, but positively associated with vegetation shade. The adult density of A. aegypti was significantly less in the parks compared with the residential areas (rate ratio [RR]; 0.09, 95% CI: 0.05–0.16), while the density of A. albopictus was significantly higher in the parks (RR: 9.99, 95% CI: 6.85–14.59). When the species were combined, the density was significantly higher in the parks (RR: 2.50, 95% CI: 1.92–3.25). The urban parks provide suitable environment for Aedes mosquitoes, and A. albopictus in particular. Virus vectors are abundant in the urban parks, and the current vector control programs need to have greater consideration of urban parks.

Aedes albopictus is commonly referred to as the ?Asian Tiger Mosquito?, a name that describes its distinctive black and white banding and its origins in Southeast Asian rainforests. This highly invasive species is a competent vector of dengue viruses (DENVs) and was the primary vector during the recent resurgence of chikungunya virus (CHIKV) in the islands of the western Indian Ocean. Ae. albopictus is also a vicious biter and can transmit dog heartworm, Dirofilaria immitis, between dogs. In the last 30 years, it has colonised many parts of Europe, North and South America and Africa. Until recently, Australia had been spared infestation by Ae. albopictus. However, widespread populations were discovered in the Torres Strait in 2005 and genetic analysis suggested that it had been repeatedly introduced from the New Guinea landmass [N.W. Beebe, L.A. Hill and A.F. van den Hurk, unpublished data]. Should Ae. albopictus become established on the mainland, it has the potential to colonise much of coastal Australia, including southern areas, thus rendering them receptive to possible DENV and CHIKV transmission.

Macrozoobenthos used as a bioindicator of the waters, this happens because of the nature of the benthos which has mpergerakan low so it got a lot of influence from the environment. This study aims to determine the condition of the river Kundur with a view the community structure of macrozoobenthos which include: species composition, abundance, diversity, uniformity and dominance as well as the physical and chemical parameters of water as a paremeter supporters. Based on the results of observations, macrozoobenthos were found during the study in the river Kundur consists of 3 phylum, 4 classes, 17 family with 11 species. The composition of the class of macrozoobenthos in the whole of the observation station consists of a Gastropod (37%), Insecta (23%), Malacostraca (20%), Polychaeta (10%) dan Malacostraca (20%). The value of an abundance ranged from 325,7 - 3309,6 ind/m3. With the value of the total abundance at Station I which is equal to 3690,1 ind/m3, Station II 3723,1 ind/m3, Station III 3692,3 ind/m3 can be categorized diversity are light polluted with the value of the index of uniformity (E) that describes the spread of the individual tends to be uniform or relatively the same. While the condition of the physical-chemical parameters and the substrate bottom of the river Kundur in general has a range of relatively homogeneous, spread evenly throughout the observation stations and still be able to support life macrozoobenthos. To the results of measurements of the parameters of physico-chemical water and substrate in the river kundur in general has a range of relatively homogeneous in the whole observation stations and still be able to support the life of the macrozoobenthos.
