Abstract

Termites were collected in June 2012 at residental area of Pt. Arun LNG by adopted casual collection and finding colony methods. Six species and four genera had been identified to belong to the higher termites (Kalotermitidae and Rhinotermitidae) and had been collected from different habitats throughtout the residential area. Those species randomly distributed which the highest species richness found at Tarakan (6 species). Residential condition with poor maintenance was contributes to inhabitant of the termites to harbour there. One of the most destructive species, Coptotermes curvignathus, has been found to attacking building as well as plants.

Abstract

A survey was conducted to explore species richness of termite at Bukit Lawang (North Sumatra) in 2012. Termites were sampled by adopting a standardized smpling protocol (Belt Transects) at different altitudes (150m, 250m, 350m). As many as 30 species and three families (Kolotermitidae, Termitidae) were collected. None of the species under Kalotermitidae collected from the field were probably related to the limited area surveyed and nesting behaviour (which generally inhabitant into dead branches and twigs)

Abstract

A taxonomic key based on soldier and worker characters for an open air processional column termites genera, Lacessititermes, was constructed from material collected from Sumatra and adjacent islands from 1998 to 2017. As many as seven species of the genus are taxonomically difficult and complicated. Soldier caste is efective to separate L. piliferus, L. longinsus, L. albipes and L. batavus while mandible characters are efective to separate L. laborator from L. sordidus. Combination of soldier and worker characters are highly useful for identification of Lacessititermes from Sumatra. Keywords: Termite, Lacessititermes, Taxonomy, Sumatra

Abstract

Hymenopteran parasitoids are biological control agents that contribute mortality to economically important pest of oil palm plantations. In this research we investigated the diversity and abundance of Hymenopteran parasitoids at PT. Mopoli Raya, Aceh Province, Indonesia. Data were collected by adopted a purposive sampling method in mature and immature plantations by using light trap, malaise trap, and yellow-pan trap.  Specimens were identified at Universitas Syiah Kuala and final taxonomic confirmation was conducted at Gadjah Mada University.  We found that the species richness and evenness of the Hymenoptera parasitoid species in mature oil palm plantations tended to be higher than in immature plantations.  It is suspected that in immature oil palm plants (4 years) synthetic pesticide application is more intensive and it has a negative impact on the presence of parasitoids compared to the mature.

Abstract

Abstract: Entomopathogenic fungi are essential to consider as one of the biological agents to control termite populations. This research aimed to molecularly identify entomopathogenic fungi isolates in termites based on the ITS rDNA region and to determine the relationship of fungi isolates. Identification was performed by DNA extraction, PCR amplification, electrophoresis, purification, and sequencing. Phylogenetic trees were generated using MEGA X.  Molecular identification showed that the ISO1 sample was Penicillium oxalicum, the ISO2 sample was Trichoderma ghanense the ISO3 sample was Aspergillus niger, the ISO4 sample was Aspergillus fumigatus and the ISO5 sample was Aspergillus pseudonomius. The phylogenetic tree showed that the ISO1, ISO2, ISO3, ISO4, and ISO5 samples had the closest relationship with Penicillium oxalicum strain FR6-CGR12, Trichoderma ghanense isolate TM2, Aspergillus niger isolate 77, Aspergillus fumigatus, and Aspergillus pseudonomius strain DTO 267D6, respectively.Abstrak: Kelimpahan jenis fungi entomopatogen adalah hal yang terpenting untuk dipertimbangkan sebagai agen hayati bagi populasi rayap.Penelitian ini bertujuan untuk mengidentifikasi secara molekular isolat fungi entomopatogen pada rayap, berdasarkan daerah ITS rDNA dan mengetahui hubungan kekerabatan dari isolat fungi tersebut. Identifikasi dilakukan dengan cara ekstraksi DNA, amplifikasi menggunakan PCR, elektroforesis, purifikasi dan sekuensing. Selanjutnya kontruksi pohon filogenetik menggunakan aplikasi MEGA X. Berdasarkan uji molekular menunjukkan bahwa sampel ISO1 merupakan Penicillium oxalicum.ISO2 merupakan Trichoderma ghanense.ISO3 merupakan Aspergillus niger. ISO4 merupakan Aspergillus fumigatus.ISO5 merupakan Aspergillus pseudonomius.Konstruksi pohon filogenetik menunjukkan bahwa, sampel ISO1 berkerabat dekat dengan Penicillium oxalicum strain FR6-CGR12. Sampel ISO2 berkerabat dekat dengan Trichoderma ghanense isolat TM2. Sampel ISO3 berkerabat dekat dengan Aspergillus nigerisolat 77. Sampel ISO4 berkerabat dekat dengan Aspergillus fumigatus.Sampel ISO5 berkerabat dekat dengan Aspergillus pseudonomius strain DTO 267D6.
