“…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.

Mosquitoes and sandflies exhibit a wide range of blood feeding patterns, targeting a wide range of vertebrate species, including birds, mammals, reptiles, and amphibians, for proteins vital for egg development. This broad host range increases the opportunity for them to acquire pathogens of numerous debilitating‐and‐fatal diseases from various animal reservoirs, playing a significant role in disease crossover between animals and humans, also known as zoonotic transmission. This review focuses on the intricate blood‐feeding habits of these dipteran vectors, their sensory systems and the complex dance between host and pathogen during disease transmission. We delve into the influence of blood sources on pathogen spread by examining the insect immune response and its intricate interplay with pathogens. The remarkable sense of smell guiding them towards food sources and hosts is explored, highlighting the interplay of multiple sensory cues in their navigation. Finally, we examine the challenges in mosquito control strategies and explore innovations in this field, emphasizing the need for sustainable solutions to combat this global health threat. By understanding the biology and behaviour of these insects, we can develop more effective strategies to protect ourselves and mitigate the burden of vector‐borne diseases.
