Anopheles farauti, Anopheles brancofti, Anopheles punctulatus, and Anopheles koliensis are confirmed as malaria vectors in West Papua. The distribution of vectors and their potency as malaria transmission differs in each ecosystem. The aim of this research was to investigate the distribution of vectors and their potency as malaria transmission found in various ecosystem. Mosquitoes were caught  by human landing collection method, Animal-Baited Trap, and livestock-baited trap. The larval surveillance was conducted in places that have potential as breeding place for Anopheles spp. Sampling sites were conducted in Manokwari, Fak-fak and Raja Ampat districts. Each District of mosquito and larva fishing is conducted in forest ecosystem near settlement, remote forest settlement, non forest near settlement, non forest remote settlement, beach near settlement and coastal remote settlement. The result of the study demonstrated that An. farauti, An. longirostris and An. punctulatus were positive from plasmodium caught in the beach near settlement, in the remote forest settlement and in non-forest near settlement ecosystems of Manokwari Regency, respectively. Anopheles farauti caught in non-forest near settlement ecosystem of Raja Ampat Regency was also found to be positive from plasmodium. However, none mosquitoes and larvae caught in Fak-fak Regency was positive. It is concluded that those mosquitoes caught in Manokwari and Raja Ampat Regency might act as vectors of Malaria.

Vector Behavior

Biak Numfor and Asmat districts reported as malaria endemic areas in Papua (Papua Global Fund, 2011). Anopheles farauti mosquito is one of the malaria vectors in the region. Malaria control efforts have been made but there are still many cases of malaria. Malaria control will provide maximum results if there is a match between the vector behavior and programs undertaken. The purpose of this study was to determine the bionomics factors (behavioral) of malaria vector An. farauti mosquitoes in coastal ecosystems (Biak Numfor) and swamp (Asmat); namely: (a). density (b) age and (c) blood-seeking behavior. The method used in this study is human landing collection, resting collection and ELISA blood-feed. The results showed that the population density of An. farauti mosquito did not have a positive relationship with the number of malaria patients in both study areas. The activity of An. farauti mosquito on blood-seeking at the coastal and swamp ecosystems lasted all night but mainly at 18:00 to 19:00 hour. The study also showed that blood-seeking activity mostly done outside of the house. Age estimation of An. farauti mosquito population at coastal ecosystems ranging from 16-18 days, while in the swamp ecosystem is 12-14 days. Population density, approximately age and blood-seeking behavior indicates that An. farauti mosquitoes on the coastal and swamp ecosystems have the potential to be an effective malaria vector.   Keywords: Malaria, Vector, Behavior

Abstract Background Ethiopia has made great strides in malaria control over the last two decades. However, this progress has not been uniform and one concern has been reported high rates of malaria transmission in large agricultural development areas in western Ethiopia. Improved vector control is one way this transmission might be addressed, but little is known about malaria vectors in this part of the country. Methods To better understand the vector species involved in malaria transmission and their behaviour, human landing collections were conducted in Dangur woreda, Benishangul-Gumuz, between July and December 2017. This period encompasses the months with the highest rain and the peak mosquito population. Mosquitoes were identified to species and tested for the presence of Plasmodium sporozoites. Results The predominant species of the Anopheles collected was Anopheles arabiensis (1,733; i.e. 61.3% of the entire Anopheles), which was also the only species identified with sporozoites (Plasmodium falciparum and Plasmodium vivax). Anopheles arabiensis was collected as early in the evening as 18:00h-19:00h, and host-seeking continued until 5:00h-6:00h. Nearly equal numbers were collected indoors and outdoors. The calculated entomological inoculation rate for An. arabiensis for the study period was 1.41 infectious bites per month. More An. arabiensis were collected inside and outside worker’s shelters than in fields where workers were working at night. Conclusions Anopheles arabiensis is likely to be the primary vector of malaria in the agricultural development areas studied. High rates of human biting took place inside and outdoor near workers’ residential housing. Improved and targeted vector control in this area might considerably reduce malaria transmission.

Dam constructions are considered a great concern for public health. The current study aimed to investigate malaria transmission in the Nyabessan village around the Memve’ele dam in South Cameroon. Adult mosquitoes were captured by human landing catches in Nyabessan before and during dam construction in 2000–2006 and 2014–2016 respectively, as well as in the Olama village, which was selected as a control. Malaria vectors were morphologically identified and analyzed for Plasmodium falciparum circumsporozoite protein detection and molecular identification of Anopheles (A.) gambiae species. Overall, ten malaria vector species were identified among 12,189 Anopheles specimens from Nyabessan (N = 6127) and Olama (N = 6062), including A. gambiae Giles (1902), A. coluzzii Coetzee (2013), A. moucheti Evans (1925), A. ovengensis Awono (2004), A. nili Theobald (1903), A. paludis Theobald (1900), A. zieanni, A. marshallii Theobald (1903), A. coustani Laveran (1900), and A. obscurus Grünberg (1905). In Nyabessan, A. moucheti and A. ovengensis were the main vector species before dam construction (16–50 bites/person/night-b/p/n, 0.26–0.71 infective bites/person/night-ib/p/n) that experienced a reduction of their role in disease transmission in 2016 (3–35 b/p/n, 0–0.5 ib/p/n) (p < 0.005). By contrast, the role of A. gambiae s.l. and A. paludis increased (11–38 b/p/n, 0.75–1.2 ib/p/n) (p < 0.01). In Olama, A. moucheti remained the main malaria vector species throughout the study period (p = 0.5). These findings highlight the need for a strong vector-borne disease surveillance and control system around the Memve’ele dam.

ABSTRACT An unprecedented malaria outbreak occurred in Ubon Ratchathani Province, northeastern Thailand, in 2014. The province showed the highest number of malaria cases of all Thai provinces. Five entomological surveys were conducted at 8 sentinel sites from September 2013 to September 2015 to address the role of different Anopheles species in malaria transmission. Mosquito collections were conducted using human landing catches and cow bait. A total of 10,369 Anopheles mosquitoes were collected and 2,240 were morphologically identified as potential malaria vectors, including An. dirus (n = 78), An. minimus (n = 18), An. sawadwongporni (n = 4), An. barbirostris s.l. (n = 819), An. philippinensis (n = 612), An. nivipes (n = 676), An. annularis (n = 42), An. aconitus (n = 7), and An. rampae (n = 142). Real-time polymerase chain reaction was used to screen for the presence of Plasmodium spp. in salivary glands. The proportion of primary vectors of surveyed villages was very low (&lt;1%), and no Plasmodium-infected specimens were detected among in the 2,240 Anopheles mosquitoes tested. The absence of positive Plasmodium samples during malaria outbreaks suggests that malaria transmission most likely occurred outside the villages, particularly in the deep-forested hilly areas that provided suitable habitats for competent malaria vectors. These results emphasize the need to develop vector control related to village community activities to reduce malaria transmission along Thailand border areas.

Abstract Anopheles barbirostris (An. barbirostris) is a malaria vector in several provinces in Indonesia. Bionomics An. barbirostris vary from region to region. The difference between bionomic and mosquito behavior affects the potential of An. barbirostris as a vector of malaria. The latest information about An. barbirostris is needed to determine the potential for malaria transmission in several provinces in Indonesia. The aim of the research was to get the latest information on An. barbirostris and the potential for malaria transmission in several provinces in Indonesia. Mosquitoes catching was carried out in several provinces in Indonesia using the human landing collection method, catching around livestocks, animal bited traps, light traps and morning resting. Larvae surveys were conducted in a place that had the potential for breeding ground place for An. barbirostris. Analysis of the presence of Plasmodium in An. barbirostris was performed using PCR. The examination results showed that An. barbirostris positive Plasmodium in South Sulawesi and Central Kalimantan. An. barbirostris’s behavior tended to be found to suck blood outside the home and some had been known to suck blood from people indoors. Fluctuation and density of An.barbirostris in April and June varied in the Provinces of West Papua, Central Kalimantan, North Kalimantan, South Sulawesi, Bali, Spesial Region of Yogyakarta (DIY), DKI Jakarta, Riau, Jambi, and Riau Islands. In general, An. barbirostris were known to suck the blood of people and animals with different percentages in each province. The breeding ground for An. barbirostris were found in rice fields, ponds, ditchesm and rivers. The potential for malaria transmission to be transmitted by An. barbirostris can occur in the provinces of South Sulawesi and Central Kalimantan.

Infectious vectors are generally sensitive to environmental change, including climatic factor. Climate may affect the ability of vector in transmitting the disease. The purpose of this study was to determine the effect of climatic factors on density of Anopheles farauti Laveran in coastal and marsh ecosystems. The mosquito was collected by using human landing collection method. The climatic data recorded during the research were air suhue, wind velocity and humidity, while the rainfall rate data was obtained from the Provincial office of Meteorology and Geophysics Agency Suhue of Papua Province. The result showed that Anopheles farauti was constantly found during the study period as air suhue, humidity, rainfall and wind velocity fluctuated. This result suggest that during the data collection climatic factors did not significantly affect the presence and density of Anopheles farauti. Key words: climatic factor; mosquito density; coastal; swamp; Anopheles farauti.
