“…The observed inhibition of hatching of eggs laid by females resulted from larvae treated with the LC 50 of the heavy metals tested as indicated in the present study was in agreement with Rayms-Keller et al, (1998) using Cd, Cu, Pb andHg against A. aegypti, Salama (2002) using Cd, Cu, Pb, Hg and Zn against C. pipiens and Kitvatanachai et al, (2005) using Pb against C. quinquefasciatus. However, Romi et al (2000) found that there were no effects on egg hatchability of Aedes albopictus treated with CuSO 4 .…”

Different concentrations of selected heavy metals in the form of cadmium chloride (CdCl 2), copper sulphate (CuSO 4), lead nitrate (Pb (NO 3) 2) and mercuric nitrate (Hg (NO 3) 2) were tested against immature and mature stage of C. pipiens to assess the toxicity, LC 50 , total carbohydrate and lipid content. The survival potential of 2 nd instar larvae was highly affected by the contamination with the tested heavy metals. On the basis of LC 50 , Cd was the most toxic metal against the larval stage followed by Hg, Cu and Pb. The late toxicity of heavy metals tested on the adult females resulted from larvae treated with the LC 50 of each heavy metal decreased significantly the number of eggs laid by female. The fecundity recorded 81.7±5.03, 90.3±2.52, 92.7±3.5 and 78.6±1.52 eggs/♀ for females resulted from larvae treated with the LC 50 of CdCl 2 , CuSO 4 , Pb (NO 3) 2 and Hg (NO 3) 2 ; respectively, compared to 186±4 eggs/♀ for control females. The hatchability percent of eggs laid with the LC 50 of CdCl 2 , CuSO 4 , Pb(NO 3) 2 and Hg (NO 3) 2 was significantly decreased to 37, 73, 80 and 39 %; respectively, compared to 97 % for eggs laid by untreated females. A significant decrease in total carbohydrate content in the whole body of males and females, C. pipiens resulted from larvae treated with the LC 50 of CdCl 2 or the LC 50 of Hg (NO 3) 2 was observed. Also, the present study showed a significant decrease in total lipid content of females by the LC 50 CuSO 4 and the LC 50 of Hg (NO 3) 2 , while in males a significant increased was caused by the LC 50 CuSO 4 and the LC 50 of Pb(NO 3) 2. It is clear from the results obtained in this study that the presence of such elements in the environmental system of the mosquito C. pipiens water as possible to contribute to the reduction of mosquito breeding.

“…The fact that some materials are less suitable for breeding could be explained by high temperature in the water of the vase, the overheating of the inner surface where eggs are laid as well as by release of toxic particles as apparently occur with some types of metallic materials (i.e. copper) (Romi et al, 2000;Vezzani & Schweigmann, 2002). This could explain the low CI recorded in glass containers and other varied materials.…”

“…graves or stationary jars) are the second most abundant container, other alternative measures are required, for example, the application of copper or larvicide-based control techniques. Adequate application of electric wire in flower pots with A. albopictus resulted very promising in reducing the immature stages in cemeteries of Europe (Romi et al, 2000;Eritja & Herreros, 2017). The use of the larvicide temephos in an environment with high availability of potential breeding sites was effective in reducing A. aegypti populations in a cemetery of Argentina (Vezzani et al, 2004).…”

Mosquitoes (Diptera: Culicidae) are important vectors of diverse pathogenic organisms, particularly arboviruses and protozoa. The immature stages of mosquitoes occur in a wide range of natural or human-made aquatic habitats. On this basis, some anthropogenic places such as cemeteries, usually serve as thrive and productive artificial-breeding habitats for mosquitoes. Despite being important foci for vector species, urban cemeteries are frequently overlooked in control and surveillance programs. This study evaluates the association of ecological variables and attributes (type of material, presence of flowers, water availability and height from the ground) of the breeding sites with the levels of infestation of mosquito immature stages. In 2017, an entire urban cemetery in Jarabacoa (Dominican Republic) was sampled at two different climatic periods (March: dry and August: rainy) for the characterization of the artificial breeding-sites, collection of immature stages of culicids and subsequent laboratory rearing for species identification. In total 968 containers were studied, containing 7 758 immature stages in 203 (21.0 %) water-filled containers which accounted for four species: Culex quinquefasciatus (50.5 %), Aedes aegypti (47.1 %), Aedes albopictus (1.9 %) and Culex nigripalpus (0.4 %). The mean of A. aegypti immatures in infested containers was roughly two times higher compared to C. quinquefasciatus and significantly lower compared to A. albopictus. The total Container Index (CI) was 20.9 %, and among the type of materials, those made from rock (cement, ceramic, and mud) and plastic had the highest CI = 25.9 % and 23.4 %, respectively. Almost 95 % of the total infested water-filled containers were made of plastic or rock. No association was found between the type of material of the containers and the density of mosquitoes. However, overall, greater densities of immature stages were found at ground than at higher levels. A weak positive correlation between water volume and density was found in some species of immature stages. Significantly higher number of C. quinquefasciatus were recorded in containers with flowers and large water volume. In contrast, A. aegypti immature stages were more frequent in containers without flowers. A weak negative association between water volume and infestations was found for A. albopictus immatures. As reflected of their opportunistic behaviour and broad ecological plasticity, Culex spp. and Aedes spp. mosquitoes were abundant pests in cemetery habitats where were able to breed in almost any kind of water-filled container regardless the type of material. However, our study showed that some ecological variables have critical impact for the development of the immature stages of some species. The health authorities and cemetery keepers can benefit from these results by focusing on the implementation of detailed plans and integrated strategies for the control and prevention of cemetery infestations by mosquitoes.

Artificial container-breeding mosquitoes, such as Aedes aegypti, Ae. albopictus, and Culex pipiens, are well-recognized vectors of diseases throughout the world. Cemeteries are considered major sources of mosquitoes and the results of more than 30 studies concerning mosquitoes in cemeteries have been published over the last decade. The characteristics of these environments in regard to the availability of resources for mosquito development were discussed. Also, studies about early detection of Aedes vectors, ecological issues, and mosquito control performed in cemeteries were reviewed. Among 31 mosquito species found breeding in cemeteries from 16 countries, the invasive Ae. aegypti and Ae. albopictus were the most frequent ones. Species of the genus Ochlerotatus, Culex, Toxorhynchites, Culiseta, Armigeres, Lutzia, Uranotaenia, and Tripteroides were also reported. Overall, cemeteries are highly suitable habitats for artificial container-breeding mosquitoes due to the great availability of the different resources that they need (i.e. sugar substances, blood, shelter and water-filled containers). In addition, these places are mostly ideal settings to perform studies in urbanized areas because of high mosquito abundance, heterogeneity of macro- and microhabitats, and an easier access in comparison with private premises. However, the feasibility of a cemetery as a study area must be evaluated in each case considering the objectives of the study and cemetery characteristics.
