Abstract

A study about ectoparasites on the small mammals at Pasar Raya Padang, West Sumatera was conducted from November 2012 to January 2013. The purpose of this study was to know the species variety of ectoparasites on the small mammals. Present study used purpossive sampling method. The results showed that, two classes (Arachnida and Insecta), two orders (Acarina and Siphonaptera), three families (Sarcoptidae, Laelapidae and Pulicidae), and four species of ectoparasites (Echinolaelaps echidninus, Laelaps nuttalli, Sarcoptes scabiei and Xenopsylla cheopis) were found on two small mammal species (Rattus tanezumi and Suncus murinus). The highest number of individuals of ectoparasites was Echinolaelaps echidninus (46 individuals) and the lowest one was Sarcoptes scabiei (9 individuals).

Abstract

The micromorphology capsule and spore are important characters for identification and clarification of problematic taxa in Bryophyta. The number of Pogonatum species in West Sumatra are still unclarified. The purpose of this study is to identify and to make a Pogonatum cluster based on micromorphology of capsule and spore characters. This study has been conducted from March to August 2013. Samples were directly collected in two exploration routes namely Cagar Alam Lembah Anai (Kandang Ampek - Mega Mendung route) and Singgalang Mountain (Pandai Sikek - Top Singgalang route). The micromorphology of capsule and spore of Pogonatum were observed using a Scanning Electron Microscope (SEM). The results showed that five species of Pogonatum (P. ciratum, P. microstomum, P. macrophyllum, P. Teysmannianum , and P. cf. urnigerum) were identified. The key characters of Pogonatum was nematodontous peristome teeth, monolete spore type, prolate spore shape with granulate and echinate ornamentation. Cluster analysis of 44 individuals indicated that Pogonatum tends to be in the same group. Based on micromorphological analysis, the results supported that Pogonatum was similar to Polytrichum. Keywords: peristome teeth, Pogonatum, Polytrichum, SEM, spore

Abstract

The morphological analysis of Puntius binotatus Valenciennes 1842 (Pisces: Cyprinidae) collected from several locations in West Sumatra has been conducted from April to June 2012. Several morphological characters were measured and analyzed using principal component analysis (PCA) and UPGMA. This study found significant morphological variations of the standard length (SL), head length (HL), least depth of caudal peduncle (HCPD), length of caudal peduncle (LCPD), eye diameter (ED), caudal fin length (CFL), caudal fin length up (CFL up), caudal fin length bottom (CFL bottom), length of maxillary barbels (LMB) and length of snout barbels (LSB). Those variations were more likely influenced by elevations and western-eastern side of Barisan Mountain in Sumatra.Keywords: Barisan Mountain, cyprinidae, morphological characters, P. binotatus

Abstract

An experiment on respiration rate of German cockroach (Blattella germanica, Dictyoptera; Blattellidae) that had been resistant to pyrethroid insecticide was done from December 2012 to Mei 2013. This experiment used completely randomized design with two treatments (with insecticide and without insecticide exposured) and three replications. The respiration rate were measured using the Scholander Respirometer. The control subject were VCRU-WHO as a susceptible strain standarized by WHO, while the resistance strains were GFA-JKT, KRSA-BDG, PLZ-SMRD and PLZ-PDG consisted of female, male and nymph Individuals. The results shown that respiration rates were not significant difference between susceptible and resistance strains on females (F: 0.373, df: 4, P: 0.823), males (F: 0.562, df: 4, P: 0.696) and nymphs (F: 0.402, df: 4, P: 0.803). The respiration rate were also not significant difference between with insecticide and without insecticide exposured, except within GFA-JKT females (F: 9.161, df: 4, P: 0.039), VCRU-WHO males (F: 11.779, df: 4, P: 0.026) and GFA-JKT nymphs (F: 8.733, df: 4, P: 0.042). Those results support that resistant cockroach do not increase respiration rate in responding insecticide exposured. Keywords: German cockroach, respiration rate, strains, insecticide exposured
