“…is found in the legs and lower abdomen. The same thing was also reported by Lendzele et al 2019 who conducted research on the bionomics of this fly species in African Cameroon. This fly is very mobile has the ability to fly high (Rochon et al 2021), hence it is not collected in this research because the collection was carried out using insect nets.…”

Abstract. Nangoy M, Sondakh E, Koneri R, Hadi UK.2021. Fly species on cows around the Tangkoko Nature Reserve, North Sulawesi, Indonesia and their role as disease vectors. Biodiversitas 23: 631-636. Climate and land-use changes in additional to livestock rearing systems play a role in the distribution, species, and population of fly pests, which may pose a risk to humans and animal health. The rearing and grazing of cows at the forest edge and in coconut plantations provide an ideal medium for the growth and development of flies. This study aimed to identify the diversity and abundance of fly species found on cows grazing in two habitat types: forest edge habitat and coconut plantation,located at the Tangkoko Nature Reserve in North Sulawesi, Indonesia. The study was conducted from April 2021 to June 2021 using 24 Ongole Crossbred cows including three adult males and three adult females (250-300 kg) and three males and three female calves (60-75 kg) in each habitat. Flies were collected using two fly nets that were swung along the cows in each habitat type with ten swings. The flies collected were identified based on morphology. A total of 6,982 flies were collected and identified to the following taxonomic groups: Muscidae family (Haematobia exigua 91.21%, Stomoxys calcitrans 1.65%, Musca crassirostris 0.67%, S. indicus 0.54%, S. sitiens 0.42%, and Musca domestica 0.11%), and Tabanidae family (Tabanus factiosus 4.91%, Tabanus striatus 0.47%, and Chrisops sp. 0.01%). The abundance of Haematobia exigua in the coconut plantation habitat was higher than in the forest edges, while the number of T. factiosus at the forest edges was higher than in the coconut plantations. Our results confirm that the presence of a variety of fly species and their abundance depends part on the grazing habitat of the cows. Further study of fly species diversity and pathogen status is critical to provide epidemiological data needed to develop control strategies to prevent the emergence of zoonotic diseases.

“…For this purpose, the blood of any warm-blooded host is sufficient, regardless of whether a host is dark-or bright-coloured, shaded or sunlit. In spite of this, blood-seeking female tabanids prefer dark and sunlit hosts [1,2,3,4,5,6,7], and this is the reason why horsefly traps usually have black decoys and are most effective in sunshine [8,9,10,11,12,13,14,15,16]. Our main assumption was that bloodseeking tabanids prefer to land on sunlit dark hosts to keep their body warm, which aids their rapid escape when the host performs such typical antiparasite reactions as removing horseflies from their coats with tail brushing, stamping and dislodging the flies, or by nibbling their skin [1,28].…”

“…Among white, brown and black cattle, black individuals are the preferred targets of Tabanus spp. horsefly attacks [7]. The attractiveness of sunlit brown horses to tabanids is about four times larger than that of sunlit white ones, and in comparison with a white horse, a brown horse spends two times longer in a tabanid-free shaded forest than in a sunny field with intense tabanid attacks [1].…”

Why do biting horseflies prefer warmer hosts? tabanids can escape easier from warmer targets

et al. 2020

Blood-sucking horseflies (tabanids) prefer warmer (sunlit, darker) host animals and generally attack them in sunshine, the reason for which was unknown until now. Recently, it was hypothesized that blood-seeking female tabanids prefer elevated temperatures, because their wing muscles are quicker and their nervous system functions better at a warmer body temperature brought about by warmer microclimate, and thus they can more successfully avoid the host's parasite-repelling reactions by prompt takeoffs. To test this hypothesis, we studied in field experiments the success rate of escape reactions of tabanids that landed on black targets as a function of the target temperature, and measured the surface temperature of differently coloured horses with thermography. We found that the escape success of tabanids decreased with decreasing target temperature, that is escape success is driven by temperature. Our results explain the behaviour of biting horseflies that they prefer warmer hosts against colder ones. Since in sunshine the darker the host the warmer its body surface, our results also explain why horseflies prefer sunlit dark (brown, black) hosts against bright (beige, white) ones, and why these parasites attack their hosts usually in sunshine, rather than under shaded conditions.

“…At present, most research focuses on the causes, early warning systems, post-disaster evaluation, and recovery following fires, snow disasters, and droughts [103,112,113]. Few studies have been conducted on insect disasters [114]. Drought and fire have consistently been grassland research hotspots in arid areas [18,46].…”

Grassland remote sensing (GRS) is an important research topic that applies remote sensing technology to grassland ecosystems, reflects the number of grassland resources and grassland health promptly, and provides inversion information used in sustainable development management. A scientometrics analysis based on Science Citation Index-Expanded (SCI-E) was performed to understand the research trends and areas of focus in GRS research studies. A total of 2692 papers related to GRS research studies and 82,208 references published from 1980 to 2020 were selected as the research objects. A comprehensive overview of the field based on the annual documents, research areas, institutions, influential journals, core authors, and temporal trends in keywords were presented in this study. The results showed that the annual number of documents increased exponentially, and more than 100 papers were published each year since 2010. Remote sensing, environmental sciences, and ecology were the most popular Web of Science research areas. The journal Remote Sensing was one of the most popular for researchers to publish documents and shows high development and publishing potential in GRS research studies. The institution with the greatest research documents and most citations was the Chinese Academy of Sciences. Guo X.L., Hill M.J., and Zhang L. were the most productive authors across the 40-year study period in terms of the number of articles published. Seven clusters of research areas were identified that generated contributions to this topic by keyword co-occurrence analysis. We also detected 17 main future directions of GRS research studies by document co-citation analysis. Emerging or underutilized methodologies and technologies, such as unmanned aerial systems (UASs), cloud computing, and deep learning, will continue to further enhance GRS research in the process of achieving sustainable development goals. These results can help related researchers better understand the past and future of GRS research studies.
