“…Insect population dynamics is an important part of insect ecology research [30][31]. In the reports on the fauna of horse stomach bot fly, the prevalence of G. pecorum was low in most countries and regions [2,13,32], but it is more common in the digestive tract of equines in Mongolia-Xinjiang and Qinghai-Tibet regions of China [12,33], central and northern Kazakhstan [14], the Republic of Mongolia [34] and the Yakut Republic of Russia [35]. This high incidence of this species showed a certain regionality.…”

Background: The departure of the mature larvae of the horse stomach bot fly from the host indicates the beginning of a new infection period, and the Gasterophilus pecorum becomes the dominant species in the desert steppe, showing its special biological characteristics. The population dynamics of G. pecorum were studied to reveal the population development rule of G. pecorum in the arid desert steppe. Method: The larvae were collected and recorded in the newly excreted feces by tracking the Przewalski’s horses (Equus przewalskii), meanwhile, the larval pupation experiments were carried out under natural conditions. Results: (a) There was a positive correlation between the survival rate and the number of larvae (r = 0.630, p < 0.01), indicating that the species development had the characteristics of centralized occurrence; (b) The main periods of mature larvae discharge were from early April to early May (peak Ⅰ) and from mid-August to early September (peak II), and the larval population curve showed a sudden spike in increase and gradual decrease at both peaks; under higher temperature, the number of adults from peak II had higher survival rate, higher pupation rate, higher emergence rate and less eclosion time than that of peak I; (c) Although it has one generation a year, the occurrence peak twice annually displaying a unique “ double rhythm development ” phenomenon, which forms a “ dual rhythm parasitism ” pressure on the local host. This phenomenon is very rare in the study of insect life history, especially in the parasite epidemiology. Conclusion: The natural discharge period of the G. pecorum larvae in Kalamaili Nature Reserve (KNR) is longer than 7 months and have the potentially long term infection effect on the host. The above phenomenon is one important reason for the local equine animals to be severely infected with equine myiasis.

“…Kejadian myiasis pada kulit paling sering dijumpai pada ternak dengan manifestasi klinis berupa furunkula, migrasi dan traumatika (Francesconi dan Lupi, 2012). Secara umum, jenis lalat yang menyebabkan myiasis termasuk dalam famili Calliphoridae (Stevens, 2003), Sarcophagidae (Giangaspero et al, 2017), Hypodermatidae (Pavlásek dan Minář, 2014), Oestridae (Zanzani et al, 2016) dan Gasterophilidae (Huang et al, 2016). Sedangkan jenis lalat yang menyebabkan myiasis furunkula adalah Dermatobia hominis (Meurer et al, 2016), Cordylobia anthropophaga (Fujisaki et al, 2008), Wohlfahrtia vigil (Dehghani et al, 2014), dan spesies Cuterebra (Crumley et al, 2011).…”

Myiasis is defined as a condition in which maggots are from certain fly species that utilize living, dead, or necrotic tissue from the host as a feed source for their growth and development and attack all types of vertebrate animals that are warm-blooded including humans. myiasis is often found in domestic animals in tropical regions throughout the world, especially in developing countries such as Indonesia and is generally associated with low levels of welfare of farmers. The diagnosis of myiasis is based on a clinical examination of wound bleeding, fever, a characteristic odor, the discovery of exudates and maggots in the wound. Myiasis treatment is generally local followed by manual removal of larvae and necrotic tissue debris. Systemic treatment usually uses broad-spectrum antibiotics especially when secondary infections occur. Disease prevention can be done by providing information to farmers to pay attention to and carry out livestock sanitation, pens, the surrounding environment and control flies using various methods. Keywords: clinical examination, disease prevention, maggot, myiasis

Oviposition by Gasterophilus pecorum on shoot tips of Stipa caucasica is a key determinant of its severe infection of the reintroduced Przewalski’s horse (Equus przewalskii). Volatiles in shoots of grasses on which Przewalski’s horse feeds, including S. caucasica at preoviposition, oviposition, and postoviposition stages of G. pecorum, S. caucasica, Stipa orientalis, and Ceratoides latens at the oviposition stage, and S. caucasica in various growth periods, were collected by dynamic headspace adsorption and analyzed by automatic thermal desorption gas chromatography-mass spectrometry. Among five volatiles with highest relative contents under three sets of conditions, caprolactam and 3-hexen-1-ol,(Z)- were common to all samples. Caprolactam was highest in C. latens at oviposition stage of G. pecorum and lowest in S. caucasica at postoviposition stage, and that of 3-hexen-1-ol,(Z)- was lowest in C. latens and highest in S. caucasica at its oviposition stage. Particularly, in S. caucasica during the three oviposition phenological stages of G. pecorum, 3-hexen-1-ol,acetate,(Z)-, 2(5H)-furanone,5-ethyl-, and 3-hexen-1-ol,acetate,(E)- were unique, respectively, to the preoviposition, oviposition, and postoviposition stages; in three plant species during the oviposition stage of G. pecorum, 3-hexen-1-ol,acetate,(Z)-, 3-hexenal, and 1-hexanol were unique to S. orientalis, acetic acid, hexanal, and 2(5H)-furanone,5-ethyl- to S. caucasica, and 1,3,6-octatriene,3,7-dimethyl-, cis-3-hexenyl isovalerate, and acetic acid hexyl ester to C. latens; in S. caucasica, 2-undecanone,6,10-dimethyl- was unique to the early growth period, acetic acid and 2(5H)-furanone,5-ethyl- to the flourishing growth period, and 3-hexen-1-ol,acetate,(Z)- and 1,3,6-octatriene,3,7-dimethyl- to the late growth period. Furthermore, substances specific to S. orientalis and C. latens were also present in S. caucasica, except at oviposition stage. Our findings will facilitate studies on G. pecorum’s adaptation to the arid desert steppe and its future control.
