“…funestus population. 3,[64][65][66][67][68][69][70][71] The longevity of An. funestus is particularly important because a higher proportion of malarial parasites can successfully develop and, combined with frequent exposure to infections still present in the local human population, can continue transmission into the wet season.…”

Abstract. Nchelenge District in Luapula Province, northern Zambia, experiences holoendemic malaria despite implementation of vector control programs. The major Anopheles vectors that contribute to Plasmodium falciparum transmission in this area had not previously been well defined. Three collections performed during the 2012 wet and dry seasons and the 2013 wet season revealed Anopheles funestus sensu stricto and Anopheles gambiae sensu stricto as the main vectors, where 80-85% of each collection was composed of An. funestus. Both vectors were found to be highly anthropophilic, and An. funestus has higher sporozoite infection rates (SIRs) and entomological inoculation rates (EIRs) year-round compared with An. gambiae: SIRs of 1.8-3.0% and 0-2.5%, respectively, and EIRs of 3.7-41.5 infectious bites per 6-month period (ib/p/6mo) and 0-5.9 ib/p/6mo, respectively. Spatial and temporal changes in each vector's dynamics and bionomics were also observed. Anopheles funestus was the predominant vector in the villages near Kenani Stream in both wet and dry seasons, whereas An. gambiae was found to be the main vector in areas near Lake Mweru during the wet season. The vector data illustrate the need for broader temporal and spatial sampling in Nchelenge and present unique opportunities to further our understanding of malarial transmission and implications for malarial control in high-risk areas.

Mosquitoes act as vector of fatal diseases such as malaria and dengue hemorrhagic fever since a long time ago. Thru its biting, it can transfer diseases from one sick individu to another 'immunologically naïve' people. Biting patterns and host preference play an important role in transmission of disease. Those two might differ among species, even between strain from different region. Geographic and some other enviromental play an important role on mosquitoes's individual ability. By knowing those factors will built better understanding on the role of mosquitoes on disease transmission Keywords: mosquitoes, transmission, parasite, hospes, geography Nyamuk merupakan serangga hematofagus terpenting dari sisi medis karena perannya sebagai vektor penyakit pada manusia. Penyebaran penyakit seperti demam berdarah, malaria, filariasis limpatik, Japanese encephalitis dan chikungunya sangat bergantung pada kemampuan dan kompetensi nyamuk dalam mempertahankan benih penyakit yang bertumbuh dalam badannya.1 Kenyataan bahwa jutaan orang di dunia hidup dalam bayangbayang terinfeksi oleh penyakit-penyakit yang ditularkan melalui nyamuk telah berlangsung sejak dahulu.1-4 Kemajuan zaman dan teknologi memberi dimensi baru dalam upaya pencegahan dan pemutusan rantai penularan penyakit, diantaranya dengan penggunaan piranti lunak komputer dalam pemetaan jenis dan wilayah geografis habitat tempat hidup nyamuk.4 Meski fenomena-fenomena baru dalam infeksi seperti strain yang resisten terhadap obat insektisida, man made breeding places atau jenis vektor baru juga bermunculan. Upaya kontrol dan pencegahan penularan dengan insektisida dan obat-obatan yang telah dilakukan dimasa lalu ternyata berkontribusi terhadap munculnya strain nyamuk yang resisten terhadap insektisida dan parasit yang resisten terhadap obat anti-parasit. 3Penyebaran penyakit yang ditularkan sangat bergantung kepada viabilitas dan kompetensi nyamuk sebagai vektor.2 Transmisi ditentukan oleh jumlah kontak nyamuk sebagai vektor dengan inang (hospes) yang digigitnya.3,4 Kapasitas vektor dan kompetensi nyamuk sebagai vektor (vectorial capacity dan vector competence) secara kasar menggambarkan kemampuan suatu jenis nyamuk sebagai vektor penular penyakit. Kapasitas vektor bersifat kuantitatif serta dipengaruhi oleh variabel seperti densitas/kepadatan dan usia nyamuk.

Predicting the Potential Role of Non-human Hosts in Zika Virus Maintenance

2017

Arboviruses are often maintained in complex cycles involving vertebrates such as mammals or birds and blood-feeding mosquitoes. However, the role of wildlife hosts in their emergence or re-emergence in human populations has received little attention. The recent emergence of Zika virus in America, and previous occurrences of chikungunya and dengue, forces us to confront a potential new disease-emergence phenomenon. Using a spatial data mining framework to identify potential biotic interactions, based on the degree of co-occurrence between different species, we identified those mammal species with the highest potential for establishing mammal-vector interactions, considering as principal vector Aedes aegypti. Seven of the top ten identified mammal species with highest potential were bats, with two of them having previously been confirmed as positive hosts for dengue in Mexico. We hope that this will raise interest of Mexican public health authorities and academic institutions to assess the role of wild hosts in the maintenance and spread of arboviruses.
