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).

(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.

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.

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.

Abstract

The herbivorous ladybird beetle Henosepilachna vigintioctopunctata depends primarily on solanaceous plants. The utilisation of a novel fabaceous host, centro (Centrosema molle), by this beetle has been reported from several regions in Southeastern Asia, but details of the distribution and feeding habits of H. vigintioctopunctata populations on centro are largely unknown. Our study aimed to gather basic information on the utilisation of centro by H. vigintioctopunctata in the Nusa Tenggara region of southeastern Indonesia. Field surveys indicated that H. vigintioctopunctata did not yet utilize centro in the wild in this region. However, in feeding-choice experiments in the laboratory, all beetle populations tested from this region had some potential to utilize centro, i.e., showed some feeding acceptance of this plant. Based on these results, we discuss the current status of the Nusa Tenggara H. vigintioctopunctata populations in using centro as a host.

Abstract

Host specificity has been a major factor in generating the tremendous diversity of phytophagous arthropods. Studies of adaptation to introduced or invasive plant species provide an opportunity to investigate incipient evolutionary changes in host specificity. We investigated the cryptic ability of the Asian tropical herbivorous ladybird beetle Henosepilachna diffinis to feed on the fabaceous weed "centro", Centrosema molle, which was introduced to Southeast Asia about 200 years ago. In laboratory choice tests using this plant and the normal host plant, Solanum torvum, adults preferred S. torvum to centro, but over half the beetles tested ate leaves of both plants. Furthermore, most first-instar larvae accepted centro during a rearing experiment, and a few of them grew to the third-instar stage, though none reached the final (fourth) instar. Henosepilachna diffinis likely acquired this incomplete acceptability of centro without any direct host-grazer interaction with centro, probably before this weed was introduced to Southeast Asia. Our results further suggest that another Henosepilachna species, H. vigintioctopunctata, might similarly have already acquired an incomplete ability to use centro when this beetle encountered it for the first time, and this triggered a subsequent host-range expansion from solanaceous plants to include centro in various parts of Southeast Asia.

Abstract

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.

Abstract

Thirteen species of macrochelid mites belonging to the genera Holostaspella, Macrocheles, Neopodocinum and Glyptholaspis were collected from a nest of honey bee Apis dorsata dorsata at Bogor Botanical Garden, Bogor, West Java, Indonesia. Of these, one species was described as new to science, two species were recorded from Indonesia for the first time, and all species were recorded from nest of Apis dorsata dorsata for the first time. Macrocheles nidus sp. nov. is similar to some species of scutatus subgroup, but it is discernible from the latter by the pilosity of dorsal setae.

Abstract

Divergent adaptation to different host plants may promote reproductive isolation between hostspecific populations in phytophagous insects, since strict preferences for different host plants act as an isolating barrier between populations on the different hosts. Moreover, a high dependence on the host plants may cause additional reproductive barriers, e.g., differences in micro-spatial distribution and phenology between host-specific populations when the host plants differ in these characters. However, few studies have specifically addressed these two types of host-plant-induced isolating barriers. Here we compared the microspatialdistribution and seasonal fluctuation of two host races of the  phytophagous ladybird beetle Henosepilachna diekei (Coleoptera: Coccinellidae: Epilachnine) in Bogor, West Java, one depending onMikania micrantha (Asteraceae) and the other on Leucas lavandulifolia (Lamiaceae). In the field, M. micrantha was far more abundant and common than L. lavandulifolia throughout the year. M. micrantha wasfound in relatively moist habitats with moderate sunlight, while L. lavandulifolia was found in dry, sunny, open habitats. Consequently, the beetles depending on M. micrantha were more common and abundant than those depending on L. lavandulifolia. Although the two host races could encounter one another where the two host plants occurred in close proximity, they infrequently did so because of strict host fidelity coupledwith differences in the abundance and habitat of the two host plants. On the other hand, we detected no evidence of host-related seasonal isolation between the two host races.Key words: host race, host shift, micro-spatial distribution, phenology, seasonal fluctuation
