Abstract

Pengendalian hayati rayap Coptotermes curvignathus dan Schedorhinotermes javanicus dengan menggunakan beberapa isolat cendawan entomopatogen merupakan salah satu alternatif untuk pengendalian rayap tanah yang ramah lingkungan. Penelitian ini bertujuan untuk mempelajari patogenisitas cendawan entomopatogen isolat Indonesia Metarhizium anisopliae, M. brunneum, B. bassiana, dan Myrothecium roridum dan menguji keefektifannya terhadap rayap tanah C. curvignathus dan S. Javanicus. Uji patogenisitas beberapa isolat cendawan entomopatogen terhadap C. curvignathus dan S. javanicus dilakukan dengan pencelupan rayap ke dalam suspensi konidia, masing-masing dengan kerapatan 0,105,5x105,106,5x106,dan 107 konidia per ml, setiap perlakuan diulang lima kali. Sporulasi pada tubuh rayap dihitung dari rayap C. curvignathus yang telah mati pada uji patogenisitas. Data yang diperoleh dianalisis dengan sidik ragam dan uji lanjut selang ganda Duncan pada taraf nyata 5%. Hubungan kerapatan konidia dengan mortalitas dan waktu aplikasi dengan mortalitas diolah dengan analisis probit. Berdasarkan hasil analisis probit dapat diperoleh nilai LC dan LT. Patogenisitas M. brunneum terhadap rayap S. javanicus dan C. curvignathus lebih tinggi dibandingkan dengan M. anisopliae, Beauveria bassiana, dan Myrothecium roridum. Sporulasi M. brunneum lebih tinggi dari pada M. roridum maupun B. bassiana dan sporulasi terendah terdapat pada B. bassiana. Viabilitas M. brunneum tidak berbeda nyata dengan M. roridum dan viabilitas B. bassiana berbeda nyata dengan M. roridum.Kata kunci : cendawan entomopatogen, M. brunneum, rayap

Abstract

Termites are social insects that play an important role in ecosystem. Habitat is a crucial factors determining diversity of termites. IPB University campus has quite diverse habitat types. In this research, we study the diversity and abundance of termite species around IPB University campus. Two methods used for data collection, i.e. baiting system with pine wood and transect survey within 10 x 10 m area. Six species of termites found belongs to two families, Termitidae (Macrotermes gilvus, Odontotermes javanicus, Microtermes insperatus, and Capritermes mohri) and Rhinotermitidae (Schedorhinotermes javanicus and Coptotermes curvignathus). The most diverse with the high abundance of these termites are found in the  rubber trees area, Faculty of Fisheries (FPI) and the forest behind the main administration building, Rectorate (REK) because this area provides an abundant source of cellulose as a food source for termites. While the building areas tend to have a lower diversity and abundance index because food sources for termites are not always available due to human activities. Non-metric multidimensional scaling analysis shows that the termites species composition is different between study area.

Abstract

Pests are often a problem with stored post-harvest products. One of the pests that often attack post-harvest products in storage is Tribolium castaneum (Herbst). The most common warehouse pest control effort is fumigation. Unwise and inappropriate application of fumigants can cause various negative impacts, such as pest resistance. Therefore, it is necessary to develop alternative control strategies that are more environmentally friendly through essential oils. The purpose of this study was to determine the effectiveness of kaffir lime (Citrus hystrix) essential oil as a botanical fumigant against T. castaneum that held at SEAMEO Biotrop Bogor. Kaffir lime leaf essential oil (KLLEO) is obtained by distillation. Tests in this study include the toxicity test of essential oils and essential oil fractions, resistance tests, and test the effect of essential oils on larval development. KLLEO n-hexane fraction caused high mortality of T. castaneum imago after 72 hours of fumigation. The LD95 KLLEO value in imago was 1.14 ml / l of air. MADJP also had high repellency activity against imago. The lowest dose of 0.03 ml/l air and the highest dose of 1.14 ml/l air showed a degree of 95.5 and 100% reliability, respectively, 6 hours after treatment. Chemical composition analysis using GCMS showed that citronella was the most dominant compound at 79.05%.Keywords: Citrus hystrix, fumigation, post-harvest pests AbstrakKEEFEKTIFAN MINYAK ATSIRI DAUN JERUK PURUT SEBAGAI FUMIGAN Tribolium castaneum (HERBST)Serangga hama seringkali menjadi masalah pada produk pascapanen yang disimpan.

Abstract

Tribolium castaneum is one of the important stored-product pests in tropical countries. Fumigation with phosphine is the most commonly method to control T. castaneum. However, long-term application of phosphine will cause resistance. The aims of this research were to study the effects of fumigant and repellent of peppermint oil Mentha piperita fraction against T. castaneum, and to identify the compounds contained in the active fraction. This research was conducted in Entomology Laboratory Seameo Biotrop and Forensic Laboratory of Indonesian Police Headquarters Jakarta, from January to October 2016. Peppermint oil was extracted by distillation from the leaves of M. piperita. Peppermint oil was fractionated by counter-current distribution method using three solvents: n-hexane, ethyl acetate, and methanol. Then, the three fractions were tested as fumigant and repellent against T. castaneum. The active fraction of essential oils were identified by GC-MS. The n-hexane fraction of peppermint (HFP) was the active fraction caused mortality on larvae and adults of  T. castaneum at 72 hours after fumigation. The LC95 values for the adults and  larvae was 1.9 % and 9.43 % , respectively. Sublethal concentration of HFP showed inhibitory activity on larvae development. Percentage of pupae transformed from treated larvae was 48.67-74.91 % and percentage of adults emerged was 9.12-16.59 %. The repellent activity of HFP on adults of T. castaneum was 86.7 % at 72 hours after treatment. The dominant compounds of HFP was β-pinene, limonene, isopulegol, menthone, isomenthon, menthol, pulegone, and trans-carane. The HFP or its compounds was potential to be develoved as botanical insecticides.

Abstract

Main insect pollinator of chayote in the neotropics is the stingless bees. In Indonesia, there is no information available on chayote pollination. Research was conducted with the objective to study the flowering phenology of chayote and the role of two specieses of stingless bees Heterotrigona itama (Cockerell) and Tetragonula laeviceps (Smith) (Hymenoptera: Apidae) on chayote pollination. Measurements included the number of staminate and pistillate flowers, volume of nectar and sugar concentration, floral handling time and visitation rate, and fruit set. Chayote plants produced more staminate flowers than pistillate flowers, with the ratio of 18:1. There was no difference in nectar volume and sugar concentration between staminate and pistillate flowers. H. itama and T. laeviceps visited both type of flowers, with the peak of daily visitation were occurred at 08:30-10:30 am local times. There were significant differences in the floral handling time and foraging rate of H. itama and T. laeviceps. Pollen load was significantly higher in H. itama (2137.50±184.49 grains) than those in T. laeviceps (1675.00±110.47 grains). H. itama seemed to deposite more pollen (14.1±4.1 grains) on stigma than T. laeviceps (9.8±3.1 grains). Flowers prevented from insect visits resulted in zero fruit set. Single flower visit by H. itama and T. laeviceps resulted in 60 and 40% fruit set, respectively. Higher percent of fruit set (80-85%) was noticed in open-pollination, suggesting that multiple visits by insect pollinators might increase the chances of successful pollination.

Abstract

Transformasi habitat seperti pengalihan hutan alam ke bentuk habitat lain mempengaruhi aktivitas kehidupan organisme penting di dalamnya. Rayap merupakan organisme penting yang mempunyai peran sebagai dekomposer. Oleh sebab itu perlu dikaji dari komposisinya pada habitat-habitat dengan tingkat ketergangguan yang bervariasi. Penelitian ini bertujuan mempelajari komposisi rayap pada beberapa tingkat ketergangguan habitat. Penelitian ini dilakukan pada empat tipe penggunaan lahan di Kabupaten Dharmasraya Provinsi Sumatera Barat, yaitu hutan alam, hutan kebun, perkebunan kelapa sawit dan permukiman. Penelitian dilakukan dengan cara observasi di lapangan dan identifikasi spesies rayap di laboratorium. Untuk observasi, dilakukan di tiap habitat dengan petak pengamatan berukuran 50 m x 10 m. Satu petak pengamatan dibagi dalam sub petak pengamatan dengan ukuran 5 m x 5 m sehingga diperoleh 20 sub petak pengamatan. Setiap sub petak pengamatan dilakukan survei selama 30 menit, sehingga total untuk satu petak pengamatan adalah 600 menit atau 10 jam. Identifikasi rayap dilakukan di laboratorium dengan berpedoman pada beberapa kunci identifikasi spesies rayap. Pada penelitian ini ditemukan 14 spesies rayap pada beberapa habitat di Kabupaten Dharmasraya. Hasil analisis terhadap feeding group, indeks keanekaragaman, indeks kekayaan dan dominansinya menunjukkan habitat hutan alam dan hutan kebun cenderung memiliki kedekatan komposisi rayap yang lebih dekat daripada komposisi rayap yang ada di perkebunan kelapa sawit dan permukiman, kemudian komposisi rayap di perkebunan kelapa sawit dan permukiman memiliki tingkat kesamaan yang lebih dekat pula.ABSTRACTThe transformation of habitats such as natural forests to other forms of habitat affects the life activities of important organisms in them. Termites are important organisms that have a role as decomposers. Therefore, it is necessary to study its composition in habitats with varying levels of disturbance. This study aims to study the composition of termites at several levels of habitat disturbance. This research was conducted on four types of land use in Dharmasraya Regency, West Sumatra Province, namely natural forest, secondary forest, oil palm plantation, and settlement. The research was conducted by observing in the field and finding termite species in the laboratory. For observations, conducted in each habitat with an observation plot measuring 50 m x 10 m. One observation plot in the observation sub-plot with a size of 5 m x 5 m in order to obtain 20 observation sub-plots. Each sub-plot was observed for 30 minutes, so that the total observations in one plot were 600 minutes or 10 hours. Termite identification is carried out in the laboratory based on several key termite discoveries. In this study, 14 species of termites were found in several habitats in Dharmasraya Regency. The results of the analysis of food groups, diversity index, richness index and dominance showed that natural forest and secondary forest tended to have closer proximity than the composition of termites in oil palm plantations and settlement and the composition of termites in oil palm plantations and settlement had high levels of even closer similarities.
