제주마의 위장관에 기생하는 Gasterophilus spp의 분류 및 분포조사
김승호 濟州大學校 農科大學 動物科學硏究所 1993 動物科學論叢 Vol.8 No.1
This paper dealt with the situation and the hatch rate of bot's eggs on the equine hairs in Cheju horse with the species grouping of the bot flies of equine(genus Gasterophilus). The prevalence and infection dynamics of Gasterophilus spp. larvae was also evaluated in the equine alimentary canal sub-mitted in this laboratory for the necropsy or from the abattoir. Samples including Gasterophilus spp larvae, bot's flies and its eggs, which were collected from the alimentary canal and equine hairs. respectively, were studied and classified by morphology The morpho-logic feature of the spines of Gasterophilus larvae were studied by scanning electron microscope 1. Gastercphilus intestinalis larvae concentrated in the nnnglandular portions of the stomach The infer-tion of second-, and third stage larvae were common in November, and from January to October. respec-tively. Casterophilus nasalis larvae were commonly identified on the gastric pylorus and upper portion of duodenum. Second stage larvae were found from October to December, and 3rd stage larvae. from january to September. 2. The hatch rate of laid eggs of Gasterophilus intestinalis was 28.4%. and that of Gasterophilus nasalis was 79.5%. The hatch rate of Gasterophilus intestinalis eggs was highest(62.5%) in December. The hatch rate of laid eggs were higher in the region of scapula(64.0%) and limbs(62:5%) than on the maned hairs. The eggs of Gasterophilus nasalis were completely hatched by October. 3. Eight hundred five Cheju horses examined in this study were infected with the eggs of Gasterophibus spp. Gasterophilus intestinalis eggs on the body regions from sixty horses were recognized in phalangeal (14.4%). in abdominal(13.8%). metacarpal, brachial and cervical regions. Gasterophilus nasalis eggs were uncommon and recognized in submandibular regions(1.4%). 4. In conclusion. the infection of imago, larvae and eggs of both Gasterophilus intestinalis and Gastero-philus nasalis were indentified in cheju horse.
