“…Moreover, they can mechanically transmit other pathogens, such as the etiologic agents of infectious diseases like African horse sickness, anthrax, bovine anaplasmosis, bovine besnoitiosis, bovine leucosis, equine infectious anemia, lumpy skin disease, and tularemia [2][3][4]. In Thailand, approximately 80 species of Tabanus and their distributions have been recorded [5][6][7]. The most common species are T. striatus, T. megalops, and T. rubidus [5,[7][8][9].…”

Tabanus spp., also known as horse flies (Diptera: Tabanidae), are important vectors of several animal pathogens. Adult females of Tabanus megalops and Tabanus striatus, which are members of the T. striatus complex, are morphologically similar and hence difficult to distinguish using morphological characteristics. In addition, molecular identification by DNA barcoding is also unable to distinguish these species. These two species can occur sympatrically with Tabanus rubidus, which is morphologically similar to T. megalops and T. striatus. Wing geometric morphometrics has been widely used in various insects to distinguish morphologically similar species. This study explored the effectiveness of landmark-based geometrics at distinguishing and identifying T. megalops, T. rubidus, and T. striatus in Thailand. Specimens were collected from different geographical regions of Thailand, and only unambiguously identified specimens were used for geometric morphometric analyses. Left wings of females of T. megalops (n = 160), T. rubidus (n = 165), and T. striatus (n = 85) were photographed, and 22 wing landmarks were used for the analysis. Wing shape was able to distinguish among species with high accuracy scores, ranging from 94.38% to 99.39%. We showed that morphologically very close species of Tabanus can be reliably distinguished by the geometry of their wing venation, and we showed how our experimental material could be used as a reference to tentatively identify new field collected specimens.

“…The highest proportion of horse flies was collected in Thailand villages (39.13%), followed by primary forests (34%) and secondary forests (26.87%). The species diversity of horse flies in primary forests was higher than in other habitats (Changbunjong et al, 2018b). In the central Amazon of Brazil a total of 169 larvae were collected.…”

Twenty-one species and one subspecies of tabanids belonging to two genera have been established on cattle and horse pastures in Central Yakutia as follows : Chrysops (6 species) and Hybomitra (15 species and one subspecies). In addition, varieties (dark forms) of two types have been found, namely, Hybomitra bimaculata var. bisignata and H. montana var. flaviceps. In Central Yakutia, the Hybomitra genus is distinguished by the greatest species diversity. Hybomitra montana montana (DI 45.29%), H. lundbecki lundbecki (DI 24.97%) and H. ciureai (DI 11.20 %) have been the dominant ones, H. arpadi (DI 5.85%), H. nitidifrons (DI 4.03%) and H. nigricornis (DI 2.97%) subdominant. In total, these species accounted for 94.31% of the collections. Two more species H. lurida (DI 1.88%) and H. lundbecki sibiriensis (DI 1.13%) have been small in number, accounting for 3.1% in the collections. The remaining 13 species and one subspecies refer to the group of rare ones and make up 2.59% in the collections. The mixed zoogeographical structure of the tabanid fauna of Central Yakutia, which is part of the middle taiga subzone, consists of three types of Palearctic fauna : Boreurasian (19 species, one subspecies), arid Afro-Eurasian (one species) and East Asian (one species). The Boreurasian type is distinguished by the greatest species diversity. The Boreurasian fauna species belong to four faunistic complexes as follows : tundra two species taiga 14 species and one subspecies, East Siberian forest one species, and forest-steppe two species. The Afro-Eurasian arid type of fauna includes a steppe complex represented by one species. The East Asian type of fauna consists of the Sino-Japanese faunistic complex, including one species.

“…(Diptera: Tabanidae)) are blood-sucking parasites of animals and humans. They are considered as important pests of livestock in Thailand, causing direct problems in animal health especially with horses, cattle, and buffaloes, and considerable economic losses [ 1 , 2 , 3 , 4 ]. Annual economic losses due to stable flies are estimated to be more than USD 2 billion in the United States [ 5 ].…”

The stable fly, Stomoxys calcitrans (Diptera: Muscidae), and the horse fly, Tabanus megalops (Diptera: Tabanidae), are important ectoparasites of livestock in Thailand. These species affect animal health and cause economic losses. This study investigated the insecticidal activity of Plectranthus amboinicus essential oil against S. calcitrans and T. megalops through contact and fumigant toxicity tests and evaluated the effects of the essential oil on these flies through histopathological and scanning electron microscopic (SEM) studies. The results of the contact toxicity test indicated that the median lethal dose against S. calcitrans and T. megalops was 12.05 and 131.41 µg/fly, and the 90% lethal dose was 45.53 and 200.62 µg/fly, respectively. The results of the fumigant toxicity test showed that the median lethal concentration against S. calcitrans and T. megalops was 1.34 and 7.12 mg/L air, and the 90% lethal concentration was 4.39 and 30.37 mg/L air, respectively. Histopathology revealed neuronal degeneration in the brain of S. calcitrans and interstitial neuronal edema of the brain and ovarian necrosis in T. megalops. No external morphological changes were observed via SEM. Given its insecticidal properties against S. calcitrans and T. megalops, P. amboinicus essential oil could be developed into a natural insecticide to control these fly species.
