Introduction The transmission of pathogens by blood-sucking insects to humans and other animals depends on vector-host interactions. As yet unexplored in Cape Verde, mosquito feeding behavior plays a crucial role in pathogen transmission. Herein, we aim to explore, through blood meal analysis, the relationship between mosquito species and common hosts in Santiago Island, Cape Verde. Methods Engorged female mosquitoes were collected through mechanical aspiration from May 2016 to December 2017 in three municipalities of Santiago Island (Praia, Santa Cruz, and Santa Catarina). Blood-feeding behavior in each municipality was assessed through blood meal analysis using an enzyme-linked immunosorbent assay (ELISA). Results We were able to determine that single-host blood meals were common in Aedes aegypti, Anopheles arabiensis, and Culex pipiens sensu lato (s.l.). In general, the mosquitoes preferred to feed on humans, dogs, and chickens, and on multiple hosts, mainly two hosts. The human blood index (HBI) was highest (i.e., 1.00) in Ae. aegypti, with the lowest value (0.40) observed in An. arabiensis. It was observed that, among single-host blood meals, the likelihood of Cx. pipiens s.l. feeding on humans was significantly high, whereas the likelihood of An. arabiensis feeding on humans was significantly low (log-odds ratio (LOR) = 0.85 and –2.44, respectively). In addition, a high likelihood of Ae. aegypti feeding on humans was observed, but this was not statistically significant (LOR = 0.85). Discussion Overall, our findings demonstrate a lack of feeding preference in Culex pipiens s.l. compared with Ae. aegypti and An. arabiensis. These results provide insights into possible parasite transmission and pathogen spillover/spillback, which threaten human/animal health and the economy in Cape Verde.

Malaria is an important public health problem, caused by Plasmodium parasites which are transmitted by female Anopheles mosquitoes that bite humans to obtain blood. The aim of this work was to identify the blood feeding sources of Anopheles female mosquitoes and calculate their entomological indices in relation to Plasmodium transmission. Mosquitoes were collected in malaria endemic localities of the Bajo Cauca and Pacific regions of Colombia using human landing catch and barrier screens, from 18:00 - 24:00 hr, in 2018-2021. Animal censuses within a radius of ∼250 meters were carried out at each sampling site. A total of 2,018 Anopheles specimens were collected and the most abundant species were Anopheles (Nys.) darlingi and Anopheles (Nys.) nuneztovari. The highest human biting rate was 77.5 bites per person per night (b/p/n) for An. nuneztovari in Córdoba-Pacific and 17.5 b/p/n for An. darlingi in Villa Grande-Bajo Cauca. Both species were active mainly in indoor unwalled rooms of the houses. Only An. nuneztovari from Córdoba-Pacific was infected with Plasmodium, with an entomological inoculation rate of 91.25 infective bites per year. Detection of blood feeding sources demonstrate that humans were the most common host, however, An. nuneztovari showed a preference for feeding on dogs and An. darlingi on pigs, dogs and Galliformes, rather than humans. These results contribute to entomological surveillance information and provide valuable data that can be used to tailor effective control interventions to minimize human-vector contact in these malaria endemic regions.

Human subcutaneous dirofilariasis, a rare zoonosis is being increasingly reported from various parts of the world. Most of the reported cases have lesions in and around the eye. The adult female dirofilariae release microfilaria into the definitive host’s blood. Various mosquitoes that serve as intermediate hosts such as Culex, Aedes and Anopheles take up the microfilariae (mf-L1) while feeding on an infected host. Microfilariae develop in the mosquitoes. The transmission to dogs or other hosts including humans occurs through mosquito bite during subsequent blood meal. Humans may be infected as aberrant (accidental) hosts, mainly by D. repens and D. immitis. D. repens usually resides subcutaneously, while D. immitis frequently ends up in the human lung. In human infections usually just one larva develops, which does not reach sexual maturity. In India, almost all reported cases of dirofilariasis in humans have involvement of face in the form of ocular dirofilariasis with a few reports on subcutaneous dirofilariasis. We report a case of human subcutaneous dirofilariasis, from western India, involving leg and showing microfilaria in tissue indicating presence of gravid female dirofilaria (sexual maturity). To the best of our knowledge, it is among rare cases of subcutaneous dirofilariasis wherein microfilariae have developed in human host.

Ayurveda, a unique formulation called Dhoopa Kalpana (Herbal fumigator) is mentioned. It is a fumigation technique mainly used in the treatment of allergic conditions. In the olden days, people used to practice Dhoopana (Fumigation) as a technique to overcome mosquitoes and there is ancient literature called Uddisa Tantra, a Sanskrit text that includes various Ayurvedic treatments where a special mentioning of herbal fumigation and is mentioned as Mashaka Nivarana Prayoga (Mosquito repellent) and based on this formulation, it is reviewed for its mosquitocide property. In this paper is suggesting few remedies to mosquitos biting problems. Generally male mosquito does not bite humans, female mosquitoes bite and suck the blood of humans because they need blood meal for the development of their eggs.

Mosquitoes are a major player in the spread of malaria, a parasite that killed an estimated 627,000 people in 2020 alone—as well as viruses like Zika and dengue. The Anopheles gambiae mosquito, common in rural Africa, is often called “the deadliest animal on Earth,” according to a 2020 study. There are about 3,500 species of mosquito, but “only about 100 are likely to bite and spread disease to humans.” The most medically important genera, Culex, Anopheles, and Aedes, carry a range of diseases, including malaria, dengue, West Nile fever, yellow fever, Zika, chikungunya, and lymphatic filariasis. Mosquito-borne diseases have been a serious scourge for humans and animals. This review aims to bring together a wealth of information and evidence about which mosquito species transmit diseases or cause health problems in Iraq. One of the most common diseases in Iraq is malaria, which is caused by the Plasmodium parasite. This disease is spread by the bite of female Anopheles mosquitoes. Anopheles mosquitoes are commonly referred to as “malaria mosquitoes” due to their association with malaria transmission. These mosquito species are best known as vectors of malaria, a life-threatening disease caused by Plasmodium parasites. They can also transmit other diseases, such as lymphatic filariasis and various forms of encephalitis. Given their role in transmitting malaria, controlling Anopheles mosquitoes is critical to preventing the spread of the disease. Strategies include residual spra

Mosquitoes are considered tiny as well as inconspicuous (hidden) insects in the world that are responsible for transmitting many of the deadliest diseases to humans. They have small, itchy bites and in some cases, causes life-threatening diseases. Mosquito-borne diseases (MBDs), including malaria, Japanese encephalitis (JE), lymphatic filariasis, Zika fever, Kala Azar, Chikungunya and dengue, are major public health concerns in different states in India which are increasing day by day. The climate of India is predominantly tropical which is very friendly for mosquito breeding and for this reason India is going to be the threat of mosquito-borne diseases looms large. Many efforts are given to control of mosquitoes and their diseases, but despite all trying they are flourishing in India also in worldwide. Mosquitoes are the member of the fly family, Culicidae and order, Diptera. Male mosquitoes do not bite. They feed on only water and nectar of plants. Female mosquitoes also feed same but they need blood so that they can able to reproduce. Thus, female ones bite humans but male ones do not. Over 400 mosquito species and subspecies (Anopheles, Aedes, Culex, Mansonia, Armigeres and more) are present in India.

The female mosquito of Mosquito-borne diseases or mosquito-borne illnesses are diseases caused by bacteria, viruses or parasites transmitted by mosquitoes. Nearly 700 million people contract mosquito-borne illnesses each year, resulting in over a million deaths. Diseases transmitted by mosquitoes include malaria, dengue, West Nile virus, chikungunya, yellow fever, filariasis, tularemia, dirofilariasis, Japanese encephal Only female mosquito bite on only warm blooded animals, they have capability to identify and target their hosts from 1–3 miles away in real time proportioning to 1500 miles in human distance. Even us, we only can identify miles far targets through vision, by the rays they emit, so do mosquitoes, they must be able to see our warmth, or our thermal images because warmth is an obligatory condition they are on the hunt and because electromagnetic radiation is the only media that has miles long atmospheric reach. then for the trap to target only female mosquitoes it must utilize their capacity to see thermal images to use warmth as attractant or a warm lure such as:. with distinct preferences, between side-by-side 37 °C, 40 °C and 42 °C thermal image footprints, they choose to go to the warmer first.

<h4>Background</h4>Malaria and dengue fever are transmitted by female mosquitoes of the Anopheles and Aedes genera, respectively. These diseases are among the most prevalent in sub-Saharan Africa, with dengue fever posing an increasingly significant threat. In this context, studying the species diversity of vectors, as well as their bionomics, including their ecological and behavioral traits, is essential for a better understanding of transmission dynamics, and for guiding appropriate vector control strategies. This study aims to characterize the species diversity and human bite rates of malaria and dengue vectors in central and northern Benin simultaneously, using a multimethod sampling approach combining larval surveys, captures on human volunteers, oviposition trap use, and pyrethrum spraying captures.<h4>Results</h4>Combined diurnal and nocturnal collections yielded a total of 2,337 adult mosquitoes across the five study communes. Species composition was dominated by the genera Aedes and Anopheles, with marked spatial heterogeneity among localities. The statistically significant intercommunal differences (p < 0.001) indicated a heterogeneous spatial distribution of the mosquito populations, which was further supported by the diversity indices. During larval surveys, 993 potential breeding sites were inspected, of which 51.0% were positive. In the study area, household containers such as buckets, jars, and jerry cans are the most abundant and productive breeding sites for Aedes. After emergence, 1,988 adult mosquitoes were identified, representing seven species: Aedes aegypti, Ae. albopictus, Ae. vittatus, Anopheles gambiae, Culex nebulosus, Cx. quinquefasciatus, and Cx. tigripes. Pyrethrum spray collection revealed five species and confirmed the presence of endophilic vectors, notably An. gambiae and Cx. quinquefasciatus. Analysis of biting activity revealed a pronounced circadian pattern: Aedes aegypti exhibited predominantly diurnal biting activity, whereas Anopheles gambiae showed a marked increase in nocturnal activity. The concurrent detection of Anopheles gambiae s.l. and Aedes aegypti during both daytime and nighttime, even at relatively low abundance levels, represents a noteworthy epidemiological signal suggesting a potential combined risk of malaria and dengue transmission.<h4>Conclusion</h4>The multimethod approach highlights the importance of integrated entomological surveillance to anticipate emerging epidemiological dynamics and adapt vector control strategies to local ecological conditions.
