Respon Adaptif Kumbang Lembing Pemakan D Aun Henospilachna Vigintioctopunctata (Fabricius) (Coleoptera: Coccinellidae: Epilachninae) Dan Tumbuhaninangnya Terhadap Musim Kemarau Didaerah Beriklim Tropis Kering Pasuruan Dan Malang - Jawatimur [Adaptive Res

Adaptive responses of an herbivorous ladybird beetle Henosepilachna vigintioctopunctata (Epilachninae) and the host plants to dry season were studied in Pasuruan and Malang, East Java. Nineteen species of host plants of the beetle have been recorded in Java, however only fiveteen species are found as preferred host plants of the beetles in Pasuruan and Malang. During the season beetles tend to prefer the plants of Datura metel, Brugmansia spp., Solanum melongena, S. torvum, S. pseudocapsicum, and 5. nigrum as their hosts and this might course strong damage to the plants.It is obvious that the beetles tend to move to the humid places to find more suitable food. It is also found that during the days of drought, the beetles feed on eggplant fruits by tunnelling into the flash of the fruits.Some of the beetles ovaries would not develop in the drought and a part of them might enter the diapause stage.Other responses of the beetles to drought will be discussed in the paper

SEASONAL MIGRATION AND COLONY BEHAVIOR OF THE TROPICAL HONEYBEE APIS DORSA TA F. (HYMENOPTERA: APIDAE)

A study on seasonal migration of the tropical honeybee, Apis dorsata wasconducted in the protected habitat of the Bogor Botanic Garden, West Jawa, Indonesia by monitoring the arrivals and departures of colonies of the honeybee. The colonies arrived in the garden during both the higher mean monthly rainfall and the lower number of rainy days per month and departed during the time of increasing the number of both total monthly rainfall and monthly rainy days. During their stay in the garden, the colonies occupied a certain location and host plant patches. Their duration of stay in the garden was variable. It was 77%, 9% and 4% of the colonies developed, stable and decreased their colony member, respectively. The colonies (23%) performed reproduction by reproducing new queens. Early arriving colonies stayed in very long periods and reproduced colony fission

Penyerbukan Pada Pinang Yaki (Areca Vestiaria) Di Kebun Raya Bogor

N. UTAMI & SIH KAHONO. 1988. Pollination on the pinang yaki (Areca vestiaria Giseke) in the Bogor Botanical Gardens. Berita Biologi 3(9): 470 -472.Morphology,flowering biology of the pinang yaki was observed at the Bogor Botanical Gardens.This plant i&imonocious and self pollinated. However,insect visitors appear to play an importantrole of fruit setting.It was showed that the number of fruits setting in isolated inflorescence were smaller than in unisolated inflorescence.During anthesis,the inflorescence were visited by ten species of insects,and Trigona iridipennis was suspected as the palm pollinator
