Abstract: a quantitative research of parasitofauna of thirty-three anuran atelopus bomolochus peters 1973 collected from seco river (80° 9'22'' lw, 5° 5'19'' ls), close to locality of chulucanas, province of morropon, department of piura, peru, in october 2000, was conducted. 13 268 specimens of parasites and seven species in total during all the survey were collected. 28 hosts were parasited (84.8 %). 13 hosts (39.4 %) showed infection with 1 parasite species, six (18.2 %), eight (24.2 %) and one (3,0 %) had two, three and four parasites species, respectively. seven parasite species with the following prevalence of infections were found: gorgoderina parvicava travassos 1922 (digenea) (6.1 %), cylindrotaenia americana jewell 1916 (cestoda) (9.1 %), batracholandros spectatus (freitas & ibá?ez 1962) freitas & ibá?ez 1965 (nematoda) (33.3 %), aplectana hylambatis (baylis 1927) (nematoda) (6.1 %), rhabdias sphaerocephala goodey 1924 (nematoda) (69.7 %), capillaria sp. (nematoda) (39.4 %), centrorhynchus sp. (acantocephala) (3.0 %). b. spectatus was the dominant species (97.8 %). the effect of length with prevalence of infection of r. sphaerocephala, a core specie was found. b. spectatus and capillaria sp. are secondary species. g. parvicava, c. americana, a. hylambatis and centrorhynchus sp. are satellite species. the relationship of helminthes parasites with a. bomolochus is discussed

Abstract: this is the first report of an ongoing study on arthropofauna of forensic importance in callao, peru using a baby pig (sus scrofa linneaus, 1758) on land as a model to determine the arthropofauna over 84 days of weekly survey between 17 july and 02 october 2 000. a total of 4,405 specimens were collected belonging to five orders and eight families: cochliomyia macellaria (fabricius, 1775) (diptera, calliphoridae) (81.62%); dermestes maculatus (de geer, 1774) (coleoptera, dermestidae) (16.35%); fannia canicularis (linnaeus, 1761) (diptera, muscidae) (0.04%); saprinus aeneus (fabricius, 1775) (coleoptera, histeridae) (1.48%); necrobia rufipes (de geer, 1775) (coleoptera, cleridae) (0.45%); linepithema humile (mayr, 1868) (hymenoptera, formicidae) (0.02%); porcellio laevis latreille, 1804 (isopoda, porcellionidae) (0.02%) and hadruroides lunatus (l. koch, 1867) (scorpionida, iuridae) (0.02%). larvae accounted for 76%, pupae 14% and adults 10% of the total collected. the arthropods were into three: necrophages (98.01%), predators (1.95%) and omnivorous (0.04%). c. macellaria were significantly higher during the decayed stage; by contrast d. maculatus was much higher in dry remains stage. the highest diversity with the shannon-weaver (h') and pielou (j) index were found during the advanced decayed stage. the absence of species of genus chrysomyia robineau-desvoidy, 1830 is discussed.

Abstract: a quantitative research of parasites of 67 endemic frog telmatobius jelskii (peters, 1863) collected from laguna tucto (76°46'11"w, 10°39'11"s) where pativilca river is originated was conducted, and was located in the province of oyon, high andean area from the department of lima, peru during september-october 2000. of the frogs collected, 23 were females and 44 males. male showed a length between 5.2 ± 0.5 cm (range = 4.0-6.4 cm) and female between 5.5 ± 1 cm (range = 3.9-7.6 cm) and were not found differences between both sexes. 86 specimens of parasite and three species in total during all the survey were collected. 28 hosts were infected (41.8%). twenty-five hosts (37.3%) showed infection with one parasite species, and three (4.5%) had two parasite species. three parasite species were found: gorgoderina parvicava travassos, 1922 (digenea: gorgoderidae) (prevalence = 40.3%; mean intensity = 3.1; mean abundance = 1.2), cylindrotaenia americana jewell, 1916 (cestoda: proteocephalidae) (prevalence = 3%; mean intensity = 1; mean abundance = 0.02) and aplectana hylambatis (baylis, 1927) (nematoda: cosmocercidae) (prevalence = 3%; mean intensity = 1; mean abundance = 0.02). g. parvicava had an overdispersed distribution and was the dominant species. an effect of sex and length with prevalence and mean abundance of infection of g. parvicava was not found. the relationship of helminthes parasites with t. jelskii is discussed. g. parvicava and c. americana are new records for t. jelskii.

Abstract: Se realizó una investigación cuantitativa de la fauna parasitaria del anfibio Atelopus bomolochus Peters 1973 (Bufonidae). treintaytres especímenes fueron colectados manualmente de las inmediaciones del río Seco (80° 9'22'' LW, 5° 5'19'' LS), en las cercanías de la localidad de Chulucanas, provincia de Morropón, departamento de Piura, Perú en octubre del 2000. En total se colectaron 7 especies y 13.268 especímenes. Veintyocho hospederos estuvieron parasitados (84,8 %). Trece hospederos (39,4 %) mostraron infección con 1 especie de parásito, seis (18,2 %), ocho (24,2 %) y uno (3,0 %) tuvieron 2, 3 y 4 especies de parásitos, respectivamente. Se encontraron siete especies de parásitos con las siguientes prevalencias de infección: Gorgoderina parvicava Travassos 1922 (Digenea) (6,1 %), Cylindrotaenia americana Jewell 1916 (Cestoda) (9,1 %), Batracholandros spectatus (Freitas & Ibá ez 1962) Freitas & Ibá ez 1965 (Nematoda) (33,3 %), Aplectana hylambatis (Baylis 1927) (6,1 %); Rhabdias sphaerocephala Goodey 1924 (Nematoda) (69,7 %), Capillaria sp.

Sólo se encontró efecto de la longitud con la prevalencia de infección de R. sphaerocephala, una especie central. B. spectatus y Capillaria sp. fueron especies secundarias. G. parvicava, C. americana, A. hylambatis y Centrorhynchus sp. fueron especies satélites.

Abstract: A quantitative research of parasites of 67 endemic frog Telmatobius jelskii (Peters, 1863) collected from Laguna Tucto (76°46'11"W, 10°39'11"S) where Pativilca River is originated was conducted, and was located in the Province of Oyon, high Andean area from the Department of Lima, Peru during September-October 2000. Of the frogs collected, 23 were females and 44 males. Male showed a length between 5.2 ± 0.5 cm (range = 4.0-6.4 cm) and female between 5.5 ± 1 cm (range = 3.9-7.6 cm) and were not found differences between both sexes. 86 specimens of parasite and three species in total during all the survey were collected. 28 hosts were infected (41.8%). twenty-five hosts (37.3%) showed infection with one parasite species, and three (4.5%) had two parasite species. Three parasite species were found: Gorgoderina parvicava Travassos, 1922 (Digenea: Gorgoderidae) (Prevalence = 40.3%; mean Intensity = 3.1; mean abundance = 1.2), Cylindrotaenia americana Jewell, 1916 (Cestoda: Proteocephalidae) (Prevalence = 3%; mean Intensity = 1; mean abundance = 0.02) and Aplectana hylambatis (Baylis, 1927) (Nematoda: Cosmocercidae) (Prevalence = 3%; mean Intensity = 1; mean abundance = 0.02). G. parvicava had an overdispersed distribution and was the dominant species. An effect of sex and length with prevalence and mean abundance of infection of G. parvicava was not found. The relationship of helminthes parasites with T. jelskii is discussed. G. parvicava and C. americana are new records for T. jelskii.

Of the fishes collected, 21 were females and 29 males. Male showed a standard length between 21-95 cm (52.6 ± 24.9) and female between 18-96 cm (43.2 ± 21.1) and was not found differences between both sexes. 358 specimens of parasite were collected in total during all the survey, with a mean abundance of 7.2 ± 3.2 (2-18). The mean parasite species richness 1.2 (1-3) was not correlated with standard body length. All hosts were parasited. Forty-two hosts (84%) showed infection with 1 parasite species, and eight (16%) had 2 parasite species. Three parasite species: Paraeurysorchis sarmientoi (Tantaleán, 1974) (Monogenea) (Prevalence = 14%, mean Intensity = 1, mean abundance = 0.14), Neobothriocephalus aspinosus Mateo & Bullock, 1966 (Cestoda) (Prevalence = 100%; mean Intensity = 7.02, mean abundance = 7.02) and Lernanthropus trachuri (Brian, 1903) (Copepoda) (Prevalence = 2%, mean Intensity = 1, mean abundance = 0.02) were found. Neobothriocephalus aspinosus had an overdispersed distribution and was the dominant species. An effect of sex and standard length with prevalence and mean abundance of infection of P. sarmientoi and N. aspinosus were not found. Paraeurysorchis sarmientoi showed the most prevalence of infection in the second gill-arch. Finally, we included a complete list of all metazoan parasites of S. violacea reported from Peru.
