Pollinators provide key services to both natural and agricultural ecosystems. Agricultural productivity depends, in part, on pollinator populations from adjacent seminatural habitats. Here we analysed the diversity of pollinator insects and its effect to seed set of mustard (Brassica rapa) planted in agricultural ecosystem near the Gunung Halimun-Salak National Park, West Java. At least 19 species of insects pollinated the mustard, and three species, i.e. Apis cerana, Ceratina sp., and Apis dorsata showed a high abundance. The higher abundance and species richness of pollinators occurred at 08.30-10.30 am and the diversity was related to the number of flowering plants. Insect pollinations increased the number of pods, seeds per pod, seed weights per plant, and seed germination. Key words: diversity, pollinator insects, social bees, solitary bees, seed set, Brassica rapa

Seed of Jatropha curcas (Euphorbiaceae) is currently established as the source for biofuel Therefore, it is important to understand the diversity insects that pollinated J. curcas inflorescence yellow flowers. We also aimed to study the pollination effects on fruit set on J. curcas. Scan sampling method were carried out to explore the insect pollinators diversity from 07.00 up to 17.00 h in every 15 minutes. Visiting frequency of pollinators insects were observed by using focal sampling. Those information together with flowering periods, flower nectar volumes, and environmental factors were used as the basic data to determine the effectiveness of insect pollination both in covered and uncovered of seed set plants. Results showed that nine species of insect pollinators were from three order (Hymenoptera, Lepidotera, and Diptera) pollinated J. curcas. Four species of Hymenoptera i.e. Prenolepis, Apis dorsata, Xylocopa confusa, and Apis cerana showed the highest abundances. The highest abundance and species richness of pollinators occurred at 08.00-10.15 and 15.00-17.15 h. Bees of X. confusa, A. cerana, and A. dorsata of Apidae are effective as insect pollinators in J. curcas plantations, due to high visited frequencies. The insect pollinators also increased fruits and seeds set of J. curcas in the uncovered experiment plants. Thereby, enhancement the three pollinator insects as part of crop management have to be considered by farmers.

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.

Longhorn beetles (Coleoptera: Cerambycidae) have an important function in the ecosystem, i.e. bioindicators, saproxylic, pollinators, and as food of other organisms. Land cover changes due to land use can disrupt the natural balance of the ecosystem, which can result in a decrease of cerambycid diversity. Cerambycid species diversity was evaluated in four land types, i.e. jungle-rubber, rubber plantations, oil palm plantations, and felled jungle-rubber. Collections of cerambycid beetles were conducted by using artocarpus trap, made by freshly cut Artocarpus heterophyllus branches. Collections of beetles were made on day 4th, 7th, 10th, 13th, and 16th after the traps were set up. In the four land-use types in Jambi province, we collected 72 species including 34 morphospecies of cerambycids, consisting of 42 species from the jungle-rubber, 39 species from rubber plantations, 16 species from oil palm plantations, and 28 species from felled jungle-rubber. Cerambycid diversity was highest in jungle-rubber (H' = 3.23), followed by rubber plantation (H' = 2.67), felled jungle-rubber (H' = 2.38), and oil palm plantations (H' = 2.01). Highest similarities of cerambycid communities occurred in the rubber plantation–felled jungle-rubber (51.2), followed by jungle-rubber–rubber plantation (50.0), rubber plantations–oil palm plantations (43.5), oil palm plantation–felled jungle-rubber (42.4), jungle-rubber–oil palm plantations (35.3), and jungle-rubber–felled jungle rubber (34.8). The number of cerambycid species and individuals collected was highest on day 7th.

Diversity of butterfly depends on the availability of food plant and habitat quality. The aims of this study were to assess diversity and flower preference of butterflies in Mount Sago, West Sumatra, Indonesia. Observations were performed by scan sampling method in four types of habitats, i.e. secondary forests, pine forests, rubber forests, and agricultural areas. Our results showed that at least 184 species of butterflies and 56 species of nectar plants have been identified in Mount Sago. Nymphalid butterfly, Neptis hylas, was the most dominant species of butterflies. Two species, i.e. Trogonoptera brookiana and Troides amphrysus, were found as the protected butterflies. Diversity of butterfly in secondary forests was highest, whereas the lowest diversity was found in pine forest. Papilionid butterflies were found frequently feeding on tube blossoms, nymphalid butterflies on head blossoms, and lycaenid butterflies on flag blossom. Our results also showed that habitat change impacts composition and diversity of butterfly.

Worker bees actively forage to supply colony necessity i.e., pollens, nectar, and resin. Flight activities of the worker bees are influenced by food availability and environmental conditions. This study aimed to measure flight activities of Lepidotrigona terminata in terms of leaving and returning to the nest (including carrying of pollen and pollen type) and their relation to environmental conditions. The observation of flight activities of L. terminata were conducted from August to December 2016, at 07.00-17.00 for 1 minute with 1 hour interval. Pollen load and pollen types were analyzed by the acetolysis method. Flight activities of leaving and returning to the nest were lower at 07.00-08.00 (1 individual/min) and at 16.00-17.00 (2 individuals/min). However, the peak activities occurred at 10.00 until 13.00 (8 and 6 individuals/min for leaving and returning to the nest, respectively). Temperature and light intensity were positively correlated with flight activities of bees that carried nectar and resin, as well as leaving the nest without garbage. The returned workers averagely carried 32,696 pollen grains from four pollen types. Based on selection index values, this stingless bee species mostly preferred Araceae (ⱳi=1.522) plant family for pollen resources to others, Anacardiaceae, Aceraceae, and Acanthaceae (x2=39.32, p<0.01).

Apis cerana has a wide distribution in Asia, including Sundaland, and is currently found in Wallacea, while the sister species, A. nigrocincta, is native in Sulawesi. The wide geographic distribution and the island isolation led to form morphological differences in the bees. The morph and wing venations are known to have a high genetic inheritance. Therefore, this research aimed to (1) analyze the landmark variation of wing venations of A. cerana from Sundaland and Wallacea, and A. nigrocincta from Sulawesi, (2) determine the relationship between these two bee species. The research was conducted by digitizing 550 wing venations based on nineteen landmarks. Our study on intraspecies showed that A. cerana Sumatra revealed a high variation in bending energy. Overall, the deformation grid of A. cerana from Sundaland has higher displacement than those from Wallacea, meaning higher variations of the Sundaland A. cerana. We found geometric morphometric markers of landmarks 16 and 17 in intraspecies and interspecies bees. Thus, these landmarks known as a cubital index can be used for species identification. The differentiation of interspecies has been shown in the PCA. Apis nigrocincta was separated from the single group of the centroid A. cerana and was supported by the Neighbor-Joining tree.

Kale (Brassica oleraceae) has small and compound floral-type and usually visited by bees, including Trigona laeviceps (Apidae: Melliponini) as pollinator which can increase fruit and seed production of many species of agricultural crops. Aims of the research were to study foraging activity and the role of T. laeviceps in seed production of kale. Three treatments were used i.e., caged crop with one colonies of T. laeviceps, open crop with one colonies of T. laeviceps and caged crop without bee. Foraging activities of T. laeviceps were observed during the flowering by using a focal sampling method and visual method. Measuring the amount of pollen was done by using glycerol and alcohol (70%) with a ratio 4:1 and pollen viability was observed in Brewbaker and Kwack solutions. Result showed that flower handling time of T. laeviceps was highest during 09.00-10.00 (36.3 seconds/flower) with foraging rate was 8.26 flowers per 5 minutes. Flower handling time was lowest during 15.00-16.00 (10.6 seconds/flower) with foraging rate was 28.6 flowers per 5 minutes. Pollen load of T. laeviceps in the caged crop (8125 grain) was higher than in open crop (3000 grain). Viability of the pollen in the caged crop (80.8%) was higher than that of open crop (31.4%). Pollination by T. laeviceps increased 141% number of pods per plant, 48% number of seeds per pod, 204% of seed weight per plant, and 177% of seed germination. Keywords: foraging activity, pollination, fruit set, pollen viability

Karakteristik zona intertidal Pantai Pancur Taman Nasional Alas Purwo berupa paparan karang mati, bebatuan, area lamun, dan area makroalga. Kondisi habitat yang heterogen ini menarik untuk diteliti, terutama dalam rangka memahami preferensi habitat populasi spesies Ophiuroidea yang ada, dengan posisi pantai yang menghadap laut lepas Samudera Hindia yang dikenal bergelombang tinggi dan berarus deras. Untuk menentukan relung yang dipilih tiap populasi Ophiuroidea, dilakukan metode road sampling dengan cara ‘tracking’ tipe-tipe habitat dengan GPS sehingga bisa dipetakan dalam peta tematik. Di atas peta ini, kemudian di gambarkan posisi (dengan GPS) tiap individu Ophiuroidea yang ditemukan. Penggambaran peta sebaran tersebut menggunakan program ArcGIS 9.3. Persebaran Ophiuroidea di wilayah Pantai Pancur tidak merata dan cenderung mengelompok pada wilayah yang terdapat substrat batu berpasir, area alga, dan area lamun. Ophiocoma scolopendrina merupakan spesies yang dominan ditemukan di Pantai Pancur dan menempati area yang paling luas dibandingkan spesies yang lain. Macrophiothrix longipeda adalah spesies yang menempati area paling sempit. Berdasarkan hasil overlay peta persebaran alga dan lamun di Pantai Pancur, Ophiuroidea menempati wilayah bersama pada substrat batu berpasir dengan area lamun dan alga Area. O. brevipes, O. annulosa, dan M. longipeda ditemukan tidak bersinggungan saat penelitian. Ini menunjukkan salah satu strategi berbagi ruang.Kata Kunci: Ophiuroidea, Pantai Pancur, Taman Nasional Alas PurwoABSTRACTCharacteristics of Intertidal zone Pancur Coastal Alas Purwo National Park has dead coral, bed rock, seagrass, and seaweed. This heterogeneous habitat condition is interesting to study, especially in order to understand the habitat preferences of the existing Ophiuroidea species population, with the position of the beach facing the sea off the Indian Ocean which is known to be high wave and swift flow. For determine the niche chosen by each Ophiuroidea population, the road sampling method is carried out by means of 'tracking' habitat types with GPS so that they can be mapped on thematic maps. On this map, then describe the position (with GPS) of each Ophiuroidea individual found. The depiction of the distribution map uses the ArcGIS 9.3 program. The distribution of Ophiuroidea in the Pancur Beach area is uneven and tends to cluster in areas with sandy stone substrates, algae areas, and seagrass areas. Ophiocoma scolopendrina is the dominant species found on Pancur Beach and occupies the most extensive area compared to other species. Macrophiothrix longipeda is a species that occupies the narrowest area. Based on the results of overlaying maps of algae and seagrass distribution in Pancur Beach, Ophiuroidea occupied a shared area on sandy rock substrate with seagrass areas and seaweed Area Ophiocoma brevipes, Ophiomastix annulosa, and M. longipeda found not intersecting during the study. This shows one of the space sharing strategies. Keywords: Ophiuroidea, Pancur Coast, Alas Purwo National Park
