Abstract

Vertical distributions of scarabaeids dung beetles (Coleoptera: Scarabaeidae) were studied in a tropical mountaineous rainforest of Gede-Pangrango National Park using human dung traps. Samples were collected at four different altitudes of 500-1000m, 1001-1500, 1501-2000 and 2001-2500m of five different collection sites (Cibodas, Selabintana, Situ Gunung, Bodogol, and Gunung Putri). As many as 1052 individuals of 28 species of scarabaeid dung beetles that belonging to five genera were collected.Onthophagus was the most diverse group, which consists of 21 species (75% of collected species) and followed by Copris with 3 species (10.7%), Paragymnopleurus with 2 species (7.1%), Catharsius with 1 species (3.6%), and Phacosoma with 1 species (3.6%). The Shanon-Winner index of diversity and evenness gradually declined with the increase of altitudes. The different of environment conditions on each altitude might affect to the diversity, abundance, and distribution of dung beetles. The diversity of dung beetles at the interval of 1001-1500m and 1501-2000m were not so high but abundance and similarity were high. Diversity index, evenness, abundance, and species similarity of dung beetles at the interval of 2001-2500m was low because of unfavorable habitat. Although the diversity of dung beetles at the interval 500-1000m was the highest, however abundance and similarity index were relatively low. Analyze of diversity, abundance, evenness, and similarity indexes of dung beetles on each of the different altitudes and environment conditions were discussed in this paper.

Abstract

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.

Abstract

Study on diversity and abundance of Orthoptera (insect) was conducted at a tropical mountainous rainforest of Java, Mounts Kendeng and Botol, Gunung Halimun National Park, West Java, Indonesia, from January to March 2002. Total Orthoptera captured was 414 individuals,consist of 25 species and 9 families. Shannon Diversity Index and evenness were higher at Mount of Kendeng (2.44 and 0.81) rather than Mount Botol (1.80 and 0.66).Similarity Index of Jaccard and Sorenson of both localities were similar (0.40 and 0.32).Relative abundant of each family and species will be compared between the two locations also.

Abstract

Epilaehna sp. aff. emarginata had been considered as a specialist on Mikania micrantha (Compositae). However, recently its oceurrence on Leucas lavandulifolia (Labiatae) was reported. Preliminary field observations of some beetle populations showed that they had different on the host plant utilizations. However, the result was not sufficient to interpret the food preference of the beetles. These experiments weremade in order to clarify those previous observations.Experiments on adult food preference was investigated under uncontrolled room conditions.Four beetle populations (Bogor, Cibinong, Klaten and Malang) were subjected to choice tests offering Mikania micrantha (Compositae) and Leucas lavandulifolia. These experiments indicated that individual beetle has similar trend on food preference within each population. Bogor and Cibinong populations preferred to feed on both M. micrantha and L. lavandulifolia while. Klaten and Malang populations preferred exclusively on L. lavandulifolia. The populations showed different food preferences on the different geographical conditions of Java.

Abstract

Study on fluctuation of rainfall and insect community was conducted in a tropical forest, Gunung Halimun National Park. Ten years rainfall data was available to discuss their fluctuations. Rainfall was relatively non-seasonal with high number of almost entire monthly rainfalls.Although fluctuation of rainfall in GHNP did not show clear seasonal trend, however appearance of less rainfall showed from June to September. There were several slight fluctuations in the number of rainfalls from a month to another and some time showed major and minor peaks. Monthly dry months had never reached 0 mm. In ordinary years, only one-month drought occurred in July 1991 (90 mm) and December 2000 (8 mm). Strong drought occurred only during El Nino of 1994 and 1997, which have 3 to 4 dry months. Fluctuation of insect community was studied from March 2000 up to February 2001. Two insect collection methods were applied by setting up light traps and pitfall traps. Total individual of each order of insect counted monthly and to be compared one to another. Changing the number of monthly individual of each order was interpreted to the number of monthly rainfall in order to analyze the relation of changing of the number of rainfall and the individual of each order of the insect collected. Fluctuation of the number of monthly rainfall was synchronous to the number of insect community collected by light traps (night flying insect) but tend to opposite to the number of insect collected by pitfall traps (ground insect).

Abstract

Study of diversity and abundance of social bees (Apidae) in the pesticide-applied seasonal crops were carried out for nine species of crops in a lowland area, Dramaga, Bogor and on 17 species of crops ina highland area, Lembang, Bandung, both in the province of West Java. Two species of honey bees (Apis cerana and A. dorsata) and one species of stingless bee (Trigonalaeviceps) were recorded from the lowland crops,while only A. cerana was found in the highland crops. The most abundant bee species on both low and highland was the honey bee A. cerana. The number of A. cerananests and T. laevicepsnests in the surroundings of the study sites were relatively high. Colony members of both bee species were very active to collect nectar and pollen from flowers in non-pesticide-applied sites; however, the density of bees visiting flowers in pesticide-applied seasonal crops in both lowland and highland were relatively low.

(Leguminosae) has been observed at 10 flowering plants at Cibinong, Bogor. Observation were made at 6 a.m.-6 p.m. by means of collecting insects that visit the flowers of A. villosa for 30 minute with the interval time collection of 2 hours.There were found Hymenoptera (17 species), and followed by Lepidoptera (7 species) and Diptera (3 species).The community sturcture of the insect visitors at interval of 2 hours are varies, the number increased toward the mid day, and gradually declined in the evening. This fluctuation is probably due to the nectar content during the day.
