    Abstract: Biodiversity can act as an indicator of the ecological system and as a medium for knowing species changes. Insects are living things in a world that has a high species diversity. One insect that has a functional role in the ecosystem is ants. The purpose of this study was to calculate and analyze diversity of the types of ants in four types of ecosystems and analyze the effect of habitat characteristics on the abundance of ants. Ant sampling using the hand sorting method was taken from the soil and litter parts in four ecosystems, namely secondary forest, ulin stands, oil palm plantations, and rubber stands in Sultan Thaha Syaifuddin Forest Park Batanghari District, Jambi Province. The results showed a total of 940 ants were obtained, from 296 individuals in Secondary Forest, 198 individuals in oil palm plantations, 307 individuals in ulin stand, 139 individuals in rubber stand. Ants are more commonly found in parts of the soil than litter. The highest ant diversity in the soil and litter is found in secondary forest. Environmental factors that influence the presence of ants in each ecosystem are soil temperature and thickness of litter. Keywords: ants, biodiversity, ecosystems, hand sorting, tahura.

    Abstract: Insects are among the most significant numbers of living things in the world that have many benefits. However, there are still many insects that have not been identified yet, for example, insects in mangrove ecosystems. Each age of the stand has differences in vegetation structure, so insect diversity research on each age difference of R. mucronata is essential. Sampling was collected by purposive sampling by taking three guludan samples measuring 5 m ´ 10 m. In each sample, a census was carried out to measure the diameter and height of R. mucronata at the age of 17, 13, 9, and 4 years for further vegetation analysis. The capture of insects is carried out using a yellow-pan trap and then identified to the level of morphospecies. The results showed a relationship between the age of different stands. At a young age had a lot of diversity and the highest value of insect abundance. The age of R. mucronata 13 years had the highest quantity dominated by the order Diptera Keywords: density, ecosystem, morphospecies, temperature, yellow-pan trap

    Abstract: The role of plantation forests will become more important in the future, along with the increasing demand for wood. However, pest infestation problems may represent significant obstacles to the development of sustainable forest plantations. Bagworms are one of the most important pests in Indonesian plantation forests. Outbreaks of bagworms have occurred in different tree species for wood or non-wood resources. This paper presents the first review of bagworms in Indonesian plantation forests. This review presents the diversity of bagworms, their pest status, and the factors affecting the outbreaks. More than 70 bagworm species were recorded in Indonesia, which is higher than the species richness recorded in neighboring countries. The subfamily Oiketicinae has the highest number of species, followed by Typhoniinae and Taleporiinae. The highest bagworm richness has been recorded in Western Indonesia, except for Papua, where many new species have recently been described. More than 10 species of bagworms have been reported as pests in Indonesian forest trees. Pteroma plagiophleps is currently considered the most important pest in the forestry sector because of the wide range of forest trees used as hosts. Bagworm outbreaks have been reported in forest trees since 1924. The first outbreak occurred only in pines in Sumatra. Currently, outbreaks occur in more host plants and on other islands. Bagworm outbreaks are influenced by multiple factors, such as the biology of the bagworms, their host plants and natural enemies, climate, and silvicultural practices.

    Abstract: Kutu lak (Laccifer lacca Kerr) (Homoptera: Kerriidae) merupakan serangga yang hidup secara parasitik pada tanaman inangnya. Serangga tersebut menghasilkan resin alami yang kompak dan tebal, yang menempel pada cabang tanaman tempat hidupnya yang biasa disebut lak. Lak cabang merupakan resin alami dari hasil sekresi serangga L. lacca berupa lapisan tebal lak yang membungkus ranting-ranting tanaman inang. Serangan parasitoid dan predator terhadap kutu lak berdampak langsung pada penurunan produktivitas lak. Penelitian ini bertujuan untuk mengidentifikasi parasitoid dan predator yang menyerang kutu lak, dan menghitung tingkat parasitisasi di BKPH Kabuaran dan Taman, KPH Probolinggo, Perum Perhutani Unit II Jawa Timur. Sampel lak cabang diambil dari BKPH Kabuaran dan Taman masing-masing sebanyak 200 sampel lak cabang. Masing-masing lak cabang dimasukkan ke dalam tabung reaksi. Pengamatan parasitoid yang keluar dari lak cabang dilakukan dalam tabung reaksi. Famili parasitoid yang dominan ditemukan, yaitu Aphelinidae, Encyrtidae, dan Eulophidae. Predator yang ditemukan pada kutu lak terdiri atas Famili Lathridiidae (Coleoptera), Cosmopterigidae, dan Noctuidae (Lepidoptera), Nabidae (Hemiptera), serta Chrysopidae (Neuroptera). Jumlah kumulatif parasitoid di lapangan lebih banyak (5.900 individu) dibandingkan dengan di gudang (5.263 individu). Pertambahan individu parasitoid tertinggi dari lapangan dan gudang terjadi pada pengamatan hari ke-7 sampai hari ke-17. Tingkat parasitisasi kutu lak di lapangan dan gudang tergolong tinggi dengan nilai rata-rata sebesar 93% dan 96%. Dapat disimpulkan bahwa kutu lak yang berasal dari lapangan maupun gudang mengalami serangan parasitoid yang sangat tinggi.

    Abstract: Insects are part of the forest ecosystem that plays an important role in the sustainability of the ecological functions of the forest plantations. The purpose of this study was to analyze the effect of thinning on insect communities and determine the types of insects which has potential to be bioindicators in order to assess the success of thinning in forest plantations. This research was conducted on forest plantation at the part of Forest Management Unit (BKPH) Cikawung and West Gede, Forest Management Resort (RPH) Ciguha, Forest Management Unit (KPH) Sukabumi Perum Perhutani Regional Division III West Java and Banten. The plot used in this research is a circular plot with a radius of 17.95 m. The traps used are malaise traps that is spread on thinning blocks at thinning intensity of 20%. The type of stand of thinning plots is Pinus merkusii in the age class 3. The obtained insects later identified to the morphospecies level. The results of the study show that thinning affect changes in environmental conditions and insect composition. In thinning blocks, there was decrease in the number of insect compositions by 11 families, 4 genera and also decrease of 3 morphospecies. Overall, thinning activities have no effect on changes over species richness index and evenness index of insect species. Diptera is a type of insect that can be used as a bioindicator, it states based on the consideration of ease in obtaining information related to taxonomy and biological properties, ease of identification, role of the ecosystem, pressure status and abundance parameters. Keywords: bioindicator, ecological assessment, forest disturbance

    Abstract: Kodok buduk (Duttaphrynus melanostictus) merupakan jenis kodok yang umum dijumpai di perkotaan dan keberadaannya sering diabaikan. Tujuan penelitian adalah menganalisis pemilihan pakan dari kodok buduk di habitat alamnya, kelimpahan pakan, lebar relung dan tumpang tindih relung serta mengetahui potensi kodok ini sebagai pengendali serangga hama. Analisis dilakukan pada 100 spesimen kodok buduk (50 jantan dan 50 betina) dari sekitar kampus IPB Darmaga, Bogor dengan cara pembedahan. Frekuensi pakan tertinggi di lambung jantan maupun betina kodok buduk adalah Ordo Hymenoptera, Coleoptera, Blattaria, Diplopoda, dan Isoptera. Dari segi volume, pakan tertinggi adalah Blattaria, Coleoptera, dan Scolopendromorpha, namun berdasarkan densitas relatif pakan di lambung didominasi oleh Isoptera, Hymenoptera dan Coleoptera. Ordo-ordo yang disebut di atas termasuk hama yang merugikan manusia seperti kecoak dan rayap. Tidak terdapat korelasi antara ukuran tubuh dengan volume pakan, karena terdapat bias pada data spesimen yang diambil yakni dengan ukuran tubuh 60-90 mm atau ukuran dewasa. D. melanostictus adalah satwa oportunis, namun pemilihan pakan cenderung pada jenis tertentu saja sehingga menyebabkan rendahnya nilai relung. Jantan dan betina mempunyai komposisi pakan yang sama, sehingga tumpang tindih relung menjadi tinggi. Secara umum, kodok buduk penting sebagai predator hama di daerah perkotaan.   Kata kunci: analisis kodok, kebiasaan pakan, musuh alami, sumberdaya pakan

    Abstract: Lac insect (Laccifer lacca Kerr) is phytophogus insect, that feed on Kesambi Tree (Schleichera oleosa Merr). During its life cycle, lac insect has been producing secretion in liquid form, known as LAK and having many uses, such as varnish/polish, food cover, drug capsule, cassette ribbon, etc. In 2005, Perum Perhutani has produced 60.547 kg LAK pellets, but has not fulfilled yet market demand. Cultivation technique is still conducted in a very sampling, and easy to be studied. Investment in developing lac insect is also profitable, and promising. There are two choices of management schemes in it cultivate, the first is by infecting lac insect to the host tree when the tree is 15 years old (project I) and the second is by infecting lac insect when the tree is 4 years old (project I). Financially, the Project II is more beneficial than Project I, so that the investment for project II is reasonable to be done.

    Abstract: Pest attack on the forest can have an impact on the productivity and quality of existing stands (such as reducing average plant growth, decreasing seed germination power, and appearance of forest aesthetics). This study aims to identify the types of pest management and analyze the relationship between perception and community actions in the community forest in Karyasari Village, Leuwiliang District, Bogor Regency. Data collection is done by semi-structured interview, observation and recording of secondary data. The type of pest management carried out by the community uses three pest management techniques, including chemical, mechanical and a mixture of chemical and mechanical. Farmers do not use biological techniques. Mechanical pest management is less used in society compared to chemical management. Many farmers use chemical management techniques with pesticides because they kill pests quickly. In addition, some small farmers use a mixture of chemical and mechanical management. There is a relationship of perception with the characteristics of respondents, such as land area, education and role in society. There is a relationship of action with the characteristics of respondents, such as the role in society, land area, education and employment.
