Abstract

Tomato (Solanum lycopersicum L.) is a hermaphrodite plant and capable of auto pollination. However it still need pollinators to maximize pollination success. This research was aimed to determine the diversity, foraging activity of pollinator bees and its effectiveness on seeds and fruits formation of tomato. Scan sampling method was used to determine the diversity of pollinators and focal sampling method was used to observe visiting behavior of the bees. We conducted two experiments i.e., screen caged plants and open plants to compare the effect of the bee pollinators on fruits and seeds set formation. Results showed that eleven species of bees were found, i.e., Megachile conjuncta Smith, Megachile fulfifrons Smith, Megachile unbripennis Smith, Xylocopa confusa Latreille, Xylocopa latipes Drury, Xylocopa caerulea Fabricius, Ceratina cognata Latreille, Nomia quadridentata Bingham, Amegilla cyrtandrae Lieftinck, Amegilla burneensis Friese, and Apis cerana Fabricius. Three species of bees were dominant, i.e., X. confusa, A. cyrtandrae, and C. cognata. Bee, X. confusa visited more flowers per minute, followed by A. cyrtandrae and C. cognata. The longest species visiting in plants were C. cognata, followed by X. confusa and A. cyrtandrae. Bee pollinators increase 8.92% of fruiting, 43% of fruit size, 189% of number of seeds per fruit, and 355% of weight of seeds of tomato plants.

Abstract

Cucumber is a monoceous plant and require pollinators for pollination process. Diversity and foraging activity of pollinators affect the effectiveness of pollination, which can improve the yields. The aim of this research were to study the diversity, foraging behavior, and effectiveness of insect pollinators on cucumber plants. Scan sampling was used as on of the methodology for observing pollinator diversity, while foraging behavior was observed using focal sampling. Pollination effectiveness were measured based on the number of fruit set of opened and caged plants. Fifteen species were found as pollinator of cucumber, i.e., Xylocopa confusa Pérez, Xylocopa latipes (Drury), Xylocopa caerulea Fabricius, Ceratina bryanti Cockerell, Amegilla burnensis Lieftinck, Nomia quadridentata Bingham, Nomia sp., Megachile unbripennis Smith, Megachile aff. disjuncta Fabricius, Megachile conjuncta Smith, Campsomeris javana Lepeletier, Syrphus sp., Parasyrphus sp., Eurema hecabe Linnaeus, and Vanessa cardui Linnaeus. The longest visit on cucumber flower pattern was by Syrphus sp. (50.71 seconds/flower), while the shortest visit was by X. confusa (4.78 seconds/flower). Pollination by insects increase 100% production as measured by healthy fruit per plant. Pollination also increase 77.61% of seeds number per fruit and 28.57% of seed weight.

SIH KAHONO, L.E. PUDJIASTUTI &. M. AMIR. 1987. Insect visitors on Acacia villosa Willd. Suppl. Berita Biologi. 3 : 70 - 71 Insect visitors on Acacia villosa Willd. (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.

Abstract

Agricultural land use is an artificial ecosystem. Insect pollinators are important keys to success of the agroecosystem. Converting natural landscapes to agricultural land, such as oil palm and rubber plantations, affects the insects. The research aims to study diversity and abundance of insect pollinators in three different agricultural land uses, i.e. oil palm plantation, rubber plantation, and jungle-rubber. Scan sampling method was used to explore the diversity of insect pollinators. Observations of the insects were conducted from 08.00 to 10.00 AM and 02.00 to 04.00 PM in sunny days. There were 497 individuals of insect pollinators collected, which belong to 43 species in three orders (Hymenoptera, Diptera, and Lepidoptera). Number of species and individual of insect pollinators found in rubber plantations (31 species, 212 individuals) and oil palm plantation (23 species, 188 individuals) were higher than that in jungle rubber (7 species, 97 individuals). Insect pollinators in oil palm plantations were dominated by giant honey bee (Apis dorsata) and stingless bee (Trigona sp. [=aff. T. planifrons]), whereas in rubber plantation, they were dominated by small carpenter bees (Ceratina lieftincki and Ceratina simillima), and in jungle-rubbers were dominated by hoverfly (Syrphid sp.) and Apis andreniformis. Higher foraging activities of insect pollinators occured in the morning.

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.
