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 theÃ‚Â 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.

Rayap merupakan serangga sosial yang berperan penting dalam perputaran siklus nutrisi. Di dalam sistem pencernaan rayap, terdapat simbion yang membantu proses degradasi selulosa. Penelitian ini bertujuan mengisolasi bakteri simbion yang terdapat di dalam saluran cerna rayap tanah. Penelitian diawali dengan koleksi rayap tanah di Kampus IPB University, diikuti isolasi bakteri simbion dari saluran cerna belakang (proktodeum) yang kemudian diidentifikasi berdasarkan morfologi, fisiologi, dan molekuler menggunakan gen 16S rRNA. Enam rayap tanah yang diperoleh adalah Macrotermes gilvus, Odontotermes javanicus, Microtermes insperatus, dan Capritermes mohri (Famili Termitidae); Schedorhinotermes javanicus dan Coptotermes curvignathus (Famili Rhinotermitidae). Dari enam rayap diperoleh 43 isolat dan satu isolat yang memiliki karakter umum. Isolat bakteri kode 8A_27F berwarna putih, elevasi seperti tombol dengan tepian licin. Dari uji fisiologis, isolat ini termasuk ke dalam bakteri Gram positif, berspora, dan bersifat aerob. Identifikasi dengan gen 16S rRNA menunjukkan bahwa isolat bakteri tersebut memiliki tingkat kemiripan sebesar 98% dengan spesies Bacillus endophyticus. Kata kunci: bakteri, rayap, 16S rRNA, simbion, proktodeum

ABSTRAKKopi, karet, dan kakao merupakan komoditas penting perkebunan di Indonesia. Dalam budidayanya, rayap merupakan salah satu hama penting yang menjadi kendala pada tanaman perkebunan dan dapat merugikan secara ekonomis Tulisan ini mengulas rayap sebagai hama pada tanaman kopi, karet, dan kakao, serta perkembangan pengendalian dan strategi pengelolaannya. Beberapa pendukung keberadaan rayap pada suatu areal perkebunan adalah cukup tersedianya bahan pada media tanam dan di sekitar tanaman. Gejala kerusakan yang disebabkan oleh rayap berupa gerekan pada batang dapat menyebabkan terganggunya tanaman yang berdampak pada terhambatnya pertumbuhan dan bahkan kematian tanaman. Pada perbenihan, serangan rayap sering menyebabkan kematian bibit. Teknik pengelolaan penting dalam pengendalian rayap secara kultur teknis adalah dengan menggunakan media pembibitan yang rendah bahan dan melakukan sanitasi lahan. Selain itu, penggunaan pestisida kimiawi ternyata masih menjadi andalan saat ini, sehingga dapat mencegah investasi rayap pada wilayah perkebunan dan dapat menekan tingkat kerusakan sebesar 70-100%. Namun, demikian untuk pengelolaan hama mendukung pertanian modern berkelanjutan, pengendalian rayap yang ramah lingkungan dengan basis pengendalian hayati dan nabati, yang saat ini telah banyak didukung hasil penelitian yang memadai, perlu dikembangkan dan diimplementasikan secara nyata dengan dukungan seluruh pihak.ABSTRACTCoffee, rubber, and cocoa are leading plantation commodities in Indonesia. In its cultivation, termites are one of the important pests that are a constraint on plantation crops and can be economically detrimental. One factor that supports the termites' activity in a plantation area is the availability of organic material. Symptoms of damage caused by termites are brittle stems that disrupt plants which cause stunted growth and even death of plants. The damage becomes serious in the stage of seedlings. Low organic matter media usage and field sanitation can reduce the termites' population. In addition, chemical pesticides are still a mainstay currently, so they can prevent termite investment in plantation areas and reduce damage levels by 70-100%. However, for pest management to support sustainable modern agriculture, environmentally friendly termite control based on biological and botanical control, which is completed by adequate research, needs to be developed and implemented in real terms with the support of all stakeholders.

Subterranean termites Macrotermes gilvus (Hagen) (Blattodea: Termitidae) belongs to the subfamily Macrotermitinae they are distributed widely in Southeast Asia such as Indonesia, Malaysia, Singapore, Myanmar, Philippine, Vietnam, and Thailand. Many studies on these termites have been conducted, but the study of relatedness termites from different locations are barely done. The objective of this study was analyze the relatedness between subterranean termites M. gilvus in IPB Dramaga Campus and Yanlappa Nature Reserve, Jasinga-Bogor. The termite relatedness was analyzed with agonistic behavioral approach and molecularly, technique using mitochondrial COI gene. Termites from both locations showed identical molecular relatedness, however behavioral analysis show that they belong from different parental lineages. Agonistic assessment showed that individuals from different habitat showed aggressive behaviour, whereas those that originated from the same nest do not show any aggression. Molecular detection however have failed to show.

The cabbage crop caterpillar, Crocidolomia pavonana, that can be very damaging to Brassicaceae plants in Indonesia, particularly in the Cianjur Regency. Farmers in the area have been using synthetic insecticides like emamectin benzoate to control this pest, but it seems that continuous use of these insecticides can lead to resistance in the pest. This research aimed to determine the level of resistance and distribution of emamectin benzoate in C. pavonana in Cianjur Regency. Field populations of C. pavonana were collected from five villages in three districts in Cianjur Regency. As a comparison, a laboratory population was used to determine the resistance ratio. All populations were tested for toxicity to determine the LC50. The results showed that populations of C. pavonana from Cianjur Regency were still susceptible to emamectin benzoate. Treatment at 22.08 í— 10-4 mg a.i/l concentration in 72 hours after treatment showed that the population's mortality was >90%. The resistance ratios of C. pavonana in Cianjur Regency were quite concerning (resistance indocation), with a range of 1.33–2.01 indicating resistance to emamectin benzoate was moderate. Interestingly, the Sindang Jaya population showed the highest resistance ratio. It's worth noting that over 90% of farmers in the region use this insecticide in the field, which supports the idea of resistance to the chemical. This study provided valuable insight into the distribution of insecticide used and resistance levels of C. pavonana in the area support each other.

Intense insecticide application is thought to cause a decline in bee colonies worldwide. Bees are effective pollinators in increasing the production of agricultural commodities. The stingless bee Tetragonula laeviceps (Apidae: Meliponini) is widely cultivated and found around plantations. The insecticides used in the toxicity test were imidacloprid 200 g/L, fipronil 50 g/L, lambda-cyhalothrin 25 g/L, profenofos 500 g/L, and chlorantraniliprole 50 g/L followed by a semi-field test using imidacloprid, fipronil, and profenofos insecticides on the cucumber plant. The LC50 value showed that exposure to imidacloprid, fipronil, and profenofos insecticides caused toxic effects on T. laeviceps by contact and orally. Lambda-cyhalothrin was found harmful on contact exposure, in contrast, chlorantraniliprole was harmful through oral. Classification of insecticide toxicity based on LD50 contact for imidacloprid, fipronil, lambda-cyhalothrin, and profenofos were very toxic and needed a risk assessment. However, chlorantraniliprole was classified as moderately toxic and low risk. In semi-field test results, imidacloprid and fipronil insecticides caused a significant decrease in the leave-return and bee-visiting activity on cucumber flowers. These insecticides also produced a low average yield of fruit weight. Insecticide application can affect the role of T. laeviceps as the pollinator which impacts the production of agricultural commodities.

Mulberry plant (Morus alba) is a plant that has social and economic importance. This plant development is often done to harvest the fruit and leaves. The social importance can be found in that this plant, especially in its leaves, is used in silkworm feed (Bombyx mori) and then silk is used in traditional clothes in Indonesia. Cultivation of mulberry plant (leaves and fruit) ideally by Integrated Pest Management (IPM) is necessary so that mulberry plants grow ideally and leaves have high quality and quantity without becoming a source of inoculum for pests and diseases of silkworm maintenance. Mulberry cultivation is generally carried out without using pesticide input so it is interesting in monitoring pests and natural enemies in the mulberry ecosystem. The research was conducted on two varieties of mulberry plants, namely Morus alba var. Kanva-2 and Morus cathayana in the same agroecosystem. Observation of pests and natural enemies was carried out using yellow sticky traps (YST) and pitfall traps (PFT). The orders and families found in the two varieties showed acroceridae family of 37.81% in the YST and hypogastruridae family with a value of 83.76% in the PFT observation.Keywords: IPM, Morus alba, natural enemies, pest, trapping.

Padi merupakan komoditas utama yang paling banyak dikonsumsi oleh masyarakat di Indonesia. Produksi padi mengalami fluktuasi setiap tahunnya, hal ini salah satunya disebabkan karena daya dukung nutrisi yang diperoleh oleh tanaman kurang optimal. Sumber nutrisi dapat berasal dari kombinasi pupuk hayati dan anorganik. Penelitian ini bertujuan untuk mengetahui kombinasi aplikasi pupuk hayati dan anorganik terhadap pertumbuhan padi sawah. Rancangan percobaan yang digunakan yaitu rancangan acak kelompok dengan 4 ulangan. Perlakuan disusun dalam 5 taraf pemupukan yaitu: tanpa aplikasi pupuk (P0), 1.00 dosis NPK (P1), 1.00 dosis NPK + 1.00 dosis pupuk hayati (P2), 3/4 dosis NPK + 1.00 dosis pupuk hayati (P3) dan 1/2 dosis NPK + 1.00 dosis pupuk hayati (P4). Hasil pengujian menunjukkan bahwa perlakuan P3 menghasilkan tanaman yang lebih tinggi, jumlah anakan yang lebih banyak, dan warna hijau daun yang lebih gelap dari perlakuan kontrol (P0) serta memiliki hasil yang serupa dengan perlakuan P1. Perlakuan P3 juga menghasilkan jumlah anakan produktif yang lebih banyak, meningkatkan produksi ubinan dan dugaan produktivitas gabah kering panen (GKP) dan gabah kering giling (GKG) lebih tinggi dari perlakuan kontrol (P0) dan sama banyaknya dengan P1. Hal ini berdampak pada nilai agronomi relatif yang lebih tinggi dibandingkan pupuk NPK terhadap perlakuan kontrol.Kata kunci: dosis pupuk, efektivitas agronomi relatif, gabah, mikroba

[Kuantitas dan kualitas buah mentimun dari berbagai metode penyerbukan]. Metode penyerbukan mentimun yang berbeda dapat menyebabkan efektivitas yang berbeda dalam pembentukan buah dan, pada gilirannya, menentukan hasil akhir dan kualitas buah. Penelitian ini bertujuan untuk membandingkan pengaruh penyerbukan oleh lebah T. laeviceps dan serangga penyerbuk lainnya terhadap produksi tanaman mentimun. Perlakuan yang dilakukan yaitu penyerbukan terbuka dengan bantuan T. laeviceps dan serangga penyerbuk liar, penyerbukan dengan bantuan manusia, dan penyerbukan oleh angin. Indikator yang diamati meliputi kuantitas dan kualitas hasil panen termasuk umur simpan buah. Hasil penelitian menunjukkan bahwa penyerbukan terbuka dapat meningkatkan persentase pembentukan buah, kenormalan, panjang, diameter, berat, dan jumlah biji. Namun, pada penelitian ini menunjukkan bahwa penyerbukan tidak mempengaruhi umur simpan buah mentimun.
