SRI PARYANTI WALUYO & DARJONO. 1986. Consumption and egg production of Kedu Fowl.Berita Bioiogi 3(4): 181 - 184. Four females and three males of Kedu Fowl has been subjected to an observation on egg production and consumption. The fowl was reared in individual cage for 68 days during the laying period.The observation revealed that the female consumed feed and water on an average of 94.645 gr and 254.45 ml a day respectively while the male was on an average of 105.96 gr and 294.91 ml a day.The manuvre production by the female fowl was recorded 85.81 gr per day. During the period of observation the average egg lay.ed by the female fowl was 34 eggs.In this period, the average weigt body gain on the female was 233.33 gr and on the male 41.66 gr respectively.In respect to the efficiency or raising Kedu fowl,feed and water in take.bodygain and egg production are considered important. These parameters are suggested to be applied as a basic selection of Kedu in a cage.

D.I. HARTOTO & RISTIYANTI M. MARWOTO.1986. Community structure and spatial distribution of Melanoides plicaria at Cibinua, Ujung Kulon. Berita Biologi 3(4): 155 - 158. The study was conducted during the dry and rainy seasons of the year 1983 and 1984, on upstream and downstream segment of Cibinua, Ujung Kulon National Park in order to reveal the pattern of distribution and corelation with its habitat structures.The gastropod community was dominated by M. plicaria and most the other species are found in only small number, which is in accordance with the published data of their genera distribution.Distribution of M.plicaria indicated a similar patchy pattern in all season and segment, but suspected due to different mechanisms.There is a clear individual packing phenomenon but do not distinctively shows an aggregation condition.Different corelation pattern between number of individuals per plot and weighted scores olphysical structure is found in all season and segment. Exclusive competition between the predo minant gastropod and the carnivorous and herbivorous fishes is briefly discussed.

A. KARTOHARDJONO. 19S6. Effect of resistance rice varieties to some biological charaters of Whitebacked planthopper (Sogatella furcifcra Horvarth) in the green house. Berita Biologi 3(4): 185 -188. The objective of this study was to find resistance varieties and to observe some biological characters of whitebacked pianthopper (wbph) i.e 1 heir preference, number of eggs laid, number of food consume, population development and their survival in the resistance varieties.The study was conducted in the green house, Bogor Res.lnst. for lood Crops in the dry season 1983.Results from this observation showed that the number of wbph to stay,to lay eggs, to consunv".to develop as well as to survive on susceptible varieties are greater than those on resistent varieties.On the susceptible plant the development will be poor on the contrat with their growth on the resistant plant.Therefore, this resistant plant is good to be used to control wbph in the field.

Three species of rats namely Rattus exulans, R. r. diardi and R. tiomanicus inhabiting the Bogor Botanical Garden were investigated with respect to their ectoand endoparasite fauna.All three species were infested with Laelaps nutalli, Echinolaelaps echidninus (Acarina); Hoplopleura pacifica and Polyplax reclinata (Anoplura); Xenopsylla cheopis (Siphoriaptera);Hydatigera taeniaefortnis and Viktorokara sp.(Helminth).Additional parasites were Poecilochinis sp., Polyplax spinulosa and Beaveria sp.,a new and yet to be described Troglotrematid Trematode found only R.tiomanicus.The rate of infestation is in part dependent on the age and sex of the host which is seemingly associated with the mobility and food searching capability of the host Time may play an additional role as well.

DIAH SULlSTIARINI. 1986, Leaf anatomy and the taxonomy status of Luisia latipetala. Berita Biologi 3(4) : 143 - 145.- In the recent publications, Luisia latipetala J. J. S. has always been considered as a synonym of L. zollingeri Reichenb. f. Based on an investigation of the leaf anatomy of 12 herbarium specimens (position, frequency and size of the stomata, guard cell and epidermis arrangement, sclereid distribution and cutin layer countour) it is concluded that the two species should be regarded as separate species.

An attempt was made to observe the egg development on 14 of A. carinata snails collected from a pond near the palace at the Bogor Botanical Gardens. It was found that after being incubated for 2-4 days, many of the snails laid 7 capsules, each capsule containing 3 to 27 eggs. The diameter of the capsule was between 4-7 mm, while the egg was about 0,3 mm. The embryos completed their development within 7 days and it was then followed by the egg batched in 1 to 2 days.

Avifauna di Kebun Raya Bogor diamati dan disensus selama tahun 1980 - 1981 dalam rangka penelitian tentang perubahan populasi burung di Bogor dan sekitarnya. Beberapa jenis burung yang umum terdapat di Kebun Raya sebelumnya, ternyata jumlahnya sudah sangat berkurang bahkan ada yang sudah hilang. Dilihat dari keanekaragaman jenis, avifauna di Kebun Raya menurun. Pengamatan ditemskan selama bulan April - Mei 1984 dcngan kesimpulan yang sama.
