Abstract

Maccrocheles mendAriUs are the abundant mite species found in poultry litter in Bogor Municipality. However, their potential as predators ofhouseflies eggs and larvae are yet not known. An effort to study their life cycle has been done in the laboratory with an hou/iy observation.The eggs and larvae could not be found whereas the pmtonymphal stAge Were 18.67 hours oh Average And deutonymphal Were 29.04hours.The average size of protonymphAl'stage were 33.97 X 24.53 /Urn And deutonymphal were 38.44 x 32.15 jum. All of these progeny were not known whether from the fertilized or unfertilized femAles.

Abstract

RAZALI YUSUF.1987.The influence of Phytophthora colocasiae on distribution of Colocasia esculenta varieties in Jawa island. Suppl.Berita Biologi 3 : 17 - 19.Field observation on varieties of Colocasia esculenta var.esculenta and C.esculenta var.antiquorum showed that the distribution of these two botanical varieties has distinct pattern. The population of C.esculenta var.esculenta are more prevalent in the lowland, whereas the population of C.esculenta var.antiquorum are confined to higher elevations.Differences in their succeptibility to the attack of the fungus Phytophthora colocasiae'it one important factor which determines the natural distribution of these two botanical varieties.

Abstract

Effect of Rhizobium inoculation on the growth of Glycine max L. Wilis variety was endicated based on green house experiment.The aim of the experiment was to asses the potency of the Rhizobium strain to inccrease the growth of Glycine max L.Strains of : 1 WG, 1 WS, 1 P, 16 GH, 1 LS, 1 BK, 1 KT, 1 BR, and 11 WY were used in this research. Controls treatment were uninoculated with Rhizobium strain -1 and without urea fertilizer (K1) and uninoculated and with urea fertilizer equal 100 kg ha (K2). The research design was Completely Randomized Design with three replications for each treatment.Experiment plants were harvested after 50 days.Parameters of investigation were the dry weight of canopy, roots, nodules root, total plants, number of nodules, and ?Symbiotic Capacity?.Results of this studies showed all of the Rhizobium inoculants able to form nodule. Strain 1 KT (isolate of soil from Kalampangan, Palangkaraya,Central Kalimantan) has given the best results on the growth of Glycine max L.

Abstract

Di Indonesia ada ±150 jenis tikus (Kadarsan& Boeadl 1975),namun baru beberapa jenis yang sudah diteliti kandungan cacing parasitnya (Kadarsan 1968, Brown et al. 1975, Carney & Stafford 1979).Padahal tikus dapat berperanan sebagai penyebar penyakit yang disebabkan cacing; kasus penyakit radang selaput otak yang diduga disebabkan cacing Angiostrongylus cantonensis dilaporkan pada pasien rumah sakit Kisaran, Sumatera Utara (Carney et al 1974) dan epidemi skistosomiasis pernah melanda penduduk Lindu, Sulawesi Tengah (Clarke et al. 1974).Mengingat pentingnya peranan tikus sebagai penyebar penyakit cacing pada manusia,dan karena kekayaan fauna cacing di Indonesia belum banyak diketahui maka suatu penelitian dilaksanakan di Dacrah Aliran Sungai Sekampung,Lampung.

Abstract

Proper stocking density on larval rearing of barred loach (Nemacheilus fasciatus Valenciennes, 1846) is very important in terms of obtaining the best growth and survival rate. This study was aimed to observe the growth and survival rate of barred loach subjected to different larval stocking density. Fish larvae were obtained by artificial spawning from in aquarium. Larvae were stocked on aquariums (50 × 40 × 30 cm) with three stocking density treatments (5, 10, and 15 individuals/L) and three replications. The experimental fish larvae were fed by Artemia and commercial feed (crude protein content: 30%) and feeding frequency twice per day (ad libitum). The length and weight were reassured every 10 days during 70 days of rearing period. Temperature, pH, and dissolved oxygen were measured at each treatment. Data obtained from measurements were analysed to assess the length gain, weight gain, specific growth rate (SGR), biomass gain, and survival rate. The results showed length gain of 3.35 ± 0.01, 2.94 ± 0.10, and 2.82 ± 0.15 cm and weight gain of 0.573 ± 0.023, 0.436 ± 0.018, and 0.417 ± 0.043 g in larval stocking density of 5, 10 and 15 individuals/L, respectively. Specific growth rates and biomass growth were of 6.22 ± 0.41, 5.93 ± 0.21, and 5.68 ± 0.41 %/day and 94.04 ± 5.39, 146.80 ± 3.81, and 167.24 ± 17.48 g in larval stocking density of 5, 10 and 15 individuals/L, respectively. Meanwhile, the survival rates obtained in this study were 89.13 ± 7.25, 93.13 ± 5.13, and 76.50 ± 3.54 % in larval stocking density of 5, 10 and 15 individuals/L, respectively. Increased stocking density has a negative impact on the growth and survival rate of barred loach.

Abstract

Tintomophatogemcfungus is isolated from an infected pupae ofH. thrax -L (Hesperiidae: Lepidoptera).The fungus 3 is cultured and determined as Beauveria sp.Conidia suspension of the fungi (7.6x10 conidia/ml) use as inoculant and reinoculated to five of difference larval stages.The larvae were cultured in the laboratory.The infected larvae become weak and finally died at ten days after inoculation.It is highly indication that the fungi may be potentially applicable as biocontrol agent for the insect.The fungus attack the E. thrax since the beginning of the larvae stage.

Abstract

M. AMIR & ANITA H. ATMOWIDJOJO.1985. Insect decomposers of organic materials in the kitchen gardens in Teluknaga, Citeureup and Pacet.Berita Biologi 3 (2) : 66 - 69. Studies on insect decomposers of home gardens at Teluknaga, Citeureup and Pacet were carried out to obtain information on their distribution and species diversity on plant and animal litters.The result indicated that the species composition of the insect decomposer at the three places (kecamatan) were not significantly different. It seemed that the insects were not affected by the different ground cover vegetation. Among the insect decomposers, termites were the most important. These insects were found to occupy different types of litters. The other insect decomposers, e.g. Gryllotafpa sp., Copris sp. and a species of Nitidulidae, were found in plant and animal litteis.

Abstract

Sumatra has rich diversity of orchids. The local communities in Sumatra have been used orchids as a ornamental plant, food, and medicine. Research on utilitation of orchids as medicinal plants by ethnic Batak of North Sumatra was conducted using ethnobotanical methods. The objectives of the research was to know species of orchids that were used as medicinal plants by Batak ethnic in North Sumatra. Respond-ents consisted of traditional medicine plants traders in the traditional markets and traditional healers. We found as many as seven species of 6 genera of orchids have been used as traditional medicine. Those orchids used as medicine for fever, aphrodisiac, maintain stamina, respira-tory disorders, and gastrointestinal disorders.

Abstract

NANDA UTAMI. 1986, Natural hybrid between A. pinnata and A. Obtusifolia in Bogor Botanical Garden.Berita Biologi 3(6): 297 - 300.The morphology and leaf anatomy of three collections of Arenga of incertain identity and grown in Bogor Botanical Garden are investigated and i compared with other species. The investigation showed that the characters of these collections oscillate between A pinnata and A. obtusifolia. Consequen tly it is suggested that the plants probably represent a natural hybrid of these two species.
