Pengendalian rayap selama ini lebih tergantung pada penggunaan insektisida kimia yang pada umumnya tidak ramah lingkungan. Pengendalian secara biologis, misalnya menggunakan cendawan patogen serangga, sedang dikembangkan untuk mengurangi penggunaan bahan-bahan kimia beracun tersebut. Penelitian ini bertujuan untuk menentukan efektivitas 6 strain cendawan patogen serangga, Metarizhium anisopliae (Metschnikoff) Sorokin, yang diperoleh dari berbagai lokasi, sebagai penyekat serangan rayap tanah Coptermes curvignathus. Beberapa tingkat ketebalan cendawan yang dibiakkan dalam media beras digunakan sebagai penyekat yang disusun bersama-sama dengan media pasir dan umpan blok kayu tusam (Pinus meskusii) dalam tabung reaksi. Rayap tanah sebanyak 50 ekor terdiri dari 45 ekor rayap pekerja dan 5 ekor rayap prajurit dimasukkan ke dalam masing-masing tabung reaksi, dan kemudian percobaan disimpan pada suhu kamar selama 9 hari.Hasil percobaan menunjukkan bahwa rayap pada umumnya mampu menembus cendawan penyekat, tetapi hanya rayap yang berhasil menembus penyekat dengan ketebalan 2 cm atau kurang dapat menyerang kayu umpan. Presentase kematian rayap pada umumnya tinggi pada perlakuan dengan ketebalan penyekat 4 dan 5 cm. Strain cendawan yang berasal dari Pakem (Yogyakarta) tampak paling menjanjikan, sementara peringkat di bawahnya secara berurutan adalah dari Jombang (Jawa Timur), Universitas Gadjah Mada (UGM) 1 (Yogyakarta), Bogor (Jawa Barat), Semarang (Jawa Tengah) dan UGM 2 (Yogyakarta). Ketebalan cendawan penyekat 4 sampai dengan 5 cm pada umumnya dapat menyebabkan kematian rayap yang tinggi, anatara 80 sampai dengan 100%.

The community of subterranean termite in any site is influenced by the soil condition. In three places studied six species of termites were found namely Macrotermes gilvus (Hagen), Microtermes insperatus Kemner, M. incertoides Holmgren, Odontotermes grandiceps Holmgren, Capritermes buitenzorgi Holmgren and Coptotermes havilandi Holmgren.In the yard of National Oceanological Institute Jakarta C. havilandi was responsible for the damage of the building. In the yard of Forest Product Research and Development Centre in Bogar four species of termite were observed, while at Cibodas Botanical Garden only one species was found namely C. buitenzorgi. The latter termite did not seem to cause to the building.

The result of a study on the effect of soil moisture content and temperature on subterranean termite distribution is presented in this paper.The study shows that soil moisture content and temperature has significant effect on subterranean termite distribution. Four subterronean termites namely Microtermes incertoides, M. insperatus, Macrotermes gilvus and Coptotermes curvignathus were identified at the first location (soil moisture content = 21. 71 %, soil temperature = 25. 7oc). Whereas at the second location (soil moisture content = 8.36%, soil temperature = 27.5°C) two species only were identified namely M. incertoides and M. insperatus.

ABSTRACTFamily Annonaceae known by its potential as source of botanical insectiside. Annona glabra L. (Annonaceae) has not been widely studied. This research aimed to find out the effectiveness of A. glabra seed extract against yellow butterfly (Eurema sp. larvae. The experiment was conducted at laboratory level. Seed extract was given by oral (feeding) and direct contact (spraying). GCMS analysis showed that the main active compounds of A. glabra seed extract were 9-octadecenoic acid (oleic acid) and 13-docosenoic acid or erucic acid. It exposed effective leading mortality against Eurema sp. larvae. Lethal concentration LC value of oral and spraying treatments were 8.37 50 mg/ml and 3.92 mg/ml respectively.Keywords: Annona glabra, botanical insecticide, Eurema sp. and mortalityABSTRAKFamily Annonaceae sudah diketahui memiliki potensi sebagai pestisida nabati. Nona sebrang (Annona glabra L.) adalah salah satu jenis dari famili Annonaceae yang belum banyak dipelajari. Penelitian ini bertujuan untuk menguji efektivitas ekstrak biji nona sebrang terhadap mortalitas larva kupu-kupu kuning (Eurema sp.). Penelitian dilakukan pada tingkat laboratorium. Ekstrak biji nona sebrang diberikan dengan cara oral (pemberian pakan) dan kontak langsung (penyemprotan) ke serangga uji. Hasil analisis GCMS menunjukkan bahwa senyawa aktif utama penyusun ekstrak biji nona sebrang adalah 9-octadecenoic acid (asam oleat) dan 13-docosenoic acid atau erucic acid. Senyawa tersebut terbukti efektif mematikan ulat larva Eurema sp. Nilai konsentrasi lethal (LC ) untuk 50 perlakuan penyemprotan pakan dan penyemprotan langsung ke larva masing-masing adalah 8,37 mg/ml dan 3,92 mg/ml.Kata kunci: Annona glabra; Eurema sp; insektisida nabati dan mortalitas

Survey on wood-destroying organisms attacking people's houses was carried out at Padalarang (Bandung district), Cibadak (Sukabumi districtj, and Pacet (Cianjur district). Data collection were done by interviewing and filling-out questionaire forms. Result of the investigation indicated that local timber and bamboo are used largely for house components. Wood destroying organisms found attacking the components are rotting fungi, subterranean termites, dry-wood termites, and powder post-beetles.

This paper deals with a descriptive account on the infestation of wood destroying organisms on PERUMNAS and KPR-BTN houses on the alluvial and regosol soil types, Data were collected through interviews and questionaires.Results of the investigation reveal that the untreated red meranti wood group was severely attacked by termites and fungi after 7 years old. Mean while, the treated wood was also attacked by fungi after 14 years old. Untreated kamper wood was attacked by fungi after 5 years old. whereas the untreated. keruing wood was attacked by termites and fungi after 11 years old.

This paper deals with a study on the infestation intensity of subterranean termites on three soil types in clear felled rubber plantation areas in West Java. The soil types predominating the areas are Red Podzolic, Brown Latosol and Dark Grey Grumusol. The results reveal that four species of termite Microtermes insperatus Kemner, M. incertoides Holmgren, Macrotennes gilvus (Hagen) and Capritermes buitenzorgi Holmgren are found in these areas pie termites were mostly found on the Dark Grey Grumusol soil, and the least number of termite was found at the Red Podzolic soil.The results also reveal that the soil type gave significant effect to the infestation intensity of subterranean termite, but it did not give any effect to the community of the termite.

The study was carried out at Cikampek on three different soil types namely Red Latosol, Redish Brown Latosol and Lateritie Association; Complex of Yellowish Red Podzolic, Yellow Podzolic and Regosol; Complex of Grumusol, Regosol and Mediteran.Odontotermes grandiceps Holmgren, Microtermes insperatus Kemner and Macrotermes gilvus (Hagen) seems to be common species in the above locations. The highest density was found on Complex of Yellowish Red Podzolic, Yellow Podzolic and Regosol (123 termites per test block), while the lowest one was found on Complex of Grumusol, Regosol and Mediteran (14 termites per test block). Termite attack intensity during the first, second, third and fourth period of observation in the three soil types were different.

Jamur patogen serangga Metarhizium anisopliae diketahui bersifat patogen terhadap banyak serangga termasuk rayap. Penularan terjadi melalui penyebaran spora. Efektivitas penularan oleh kasta rayap pekerja Coptotermes curvignathus yang telah terinfeksi spora jamur dari 6 isolat yang dikumpulkan dari berbagai lokasi di Jawa dievaluasi. Beberapa kelompok rayap yang terdiri dari campuran rayap pekerja yang terinfeksi spora dan yang sehat dimasukkan dalam botol kultur berisi media pasir steril yang lembab, diinkubasi dalam ruang gelap dan lembab pada suhu kamar selama 14 hari. Hasil penelitian menunjukkan bahwa persentase mortalitas rayap cenderung meningkat setelah inkubasi dibandingkan dengan sebelum inkubasi. Isolat dari Balai Penelitian Bioteknologi Perkebunan Bogor (BGR), Fakultas Pertanian Universitas Gajah Mada Yogyakarta (UGM)p dan Balai Proteksi Tanaman Perkebunan Semarang (SMG) menunjukkan efektivitas penularan yang tinggi, menyebabkan mortalitas rayap lebih dari 80% pada perlakuan rayap terinfeksi dengan konsentrasi 50%. Isolat dari Bogor tampaknya paling efektif untuk ditularkan oleh rayap pekerja ke dalam koloninya.

This paper is dealing with the influence of drying methods to feeding activity and survival of Cryptotermes cynoce- phalus drywood termite. The result shows that drying methods have an effect on feeding activity and survival of C. cynocephalus. Besides the drying methods, wood species has also an effect on such both factor. The oven method is more advantageorus than desicator method which is more selective and more practice.
