Abstract

Stroberi merupakan tanaman yang memiliki bunga hemaprodit, dimana dalam satu bunga terdapat satu pasang organ reproduktif (jantan dan betina). Tingkat kematangan organ reproduktif tersebut berbeda, sehingga peryerbukan pada bunga stroberi membutuhkan bantuan salah satunya adalah peranan dari serangga penyerbuk. Lebah madu dari jenis Apis mellifera merupakan serangga paling penting sebagai penyerbuk pada tanaman. Lebah madu dapat mengangkut serbuk sari dalam jumlah banyak dan berpengaruh terhadap jumlah produksi stroberi. Efektivitas penyerbukan serangga penyerbuk dapat dilihat dari jumlah biji dan bobot buah yang dihasilkan. Aktivitas dan efektivitas Apis mellifera dalam melakukan penyerbukan juga dipengaruhi oleh faktor lingkungan diantaranya suhu, kelembaban, dan intensitas cahaya. Penelitian ini bertujuan untuk mengetahui hubungan antara faktor lingkungan dengan aktivitas penyerbukan Apis melifera dan efektivitas penyerbukan Apis mellifera pada tanaman stroberi dalam meningkatkan bobot buah di desa Serang, Purbalingga. Penelitian dilakukan di lahan pertanian Desa Serang, Kecamatan Karangreja, Kabupaten Purbalingga, Jawa Tengah. Metode penelitian menggunakan metode survai Variabel yang diamati dalam penelitian ini adalah waktu kunjungan lebah, lama kunjungan lebah, faktor lingkungan meliputi suhu, kelembaban, dan intensitas cahaya. Adapun parameter yang diamati adalah bobot buah stroberi yang dihasilkan. Data yang diperoleh dianalisis menggunakan uji Regresi-Korelasi. Hasil penelitian menunjukan bahwa bahwa intesitas cahaya mempunyai korelasi paling tinggi (r = 0,668) terhadap bobot buah dan aktivitas penyerbukan (r = 0,768), hal ini disebabkan karena cahaya merupakan salah satu faktor lingkungan yang penting untuk mencari makanan. Efektivitas penyerbukan Apis mellifera pada tanaman stoberi pada aktivitas kunjungan yang tinggi menurunkan bobot buah stroberi.

Abstract

Abstract Phthiraptera lice is the common ectoparasite that attacks domestic chickens. Parasitic lice infestation is not lethal, but it can seriously disrupt the growth of chickens. The purpose of this study was to determine the diversity of lice species infecting domestic chickens in five villages in Purwokerto and its surroundings and to determine the infestation intensity of each species of lice infecting the body parts of domestic chickens in five villages in Purwokerto and its surroundings. This research was conducted using survey method and random sampling techniques in five villages in Purwokerto and its surroundings, namely Kedungwuluh Village, Kedungwringin Village, Kutasari Village, Karangsalam Village, and Karanggintung Village. Lice were sampled from five female and male domestic chickens in each village. Lice sampling is carried out on the head, wings, thighs, chest and legs of the chickens. Lice samples were then observed and identified under a microscope in the Laboratory of Entomology and Parasitology, Faculty of Biology, Unsoed. Lice sample data found in chickens from each location and body part were analyzed for variance using software SPSS 16 and using the Shannon-Wiener diversity index. The identification results showed that there were three species of lice species (order Phthiraptera) which were found infesting domestic chickens (Gallus gallus domesticus) in five villages in Purwokerto and its surroundings, namely Menopon gallinae, Lipeurus caponis, and Menacanthus cornutus. The three species of lice were the member of two families (Menoponidae and Philopteridae). Species diversity based on the Shannon-Wiener diversity index shows location I (H´: 0.914), location II (H´: 0.693), location III (H´: 1.066), location IV (H´: 1.081), and location V (H ´: 0.878). Interpretation from all sites indicated that sites I, III, and V had low species diversity, while sites II and IV had moderate species diversity. The intensity of lice infestation on domestic chickens (Gallus gallus domesticus) was 16.82%. The intensity of each type of lice in domestic chickens (Gallus gallus domesticus) was M. cornutus (32%), M. gallinae (30,9%), and L. caponis (21,2%).

Abstract

Spiders are crucial in controlling insect pest population. The various cultivation managements such as fertilizer and pesticide application, weeding, pruning, harvesting, and cropping system affect their diversity. In the plantation, vegetation diversification has applied various practices, including monoculture, and intercropping, which influence the spider community. Thus, this study was intended to determine the spider abundance and diversity of the tea plantation, and the intercropping field (tea and strawberry) at Serang village, Karangreja Sub-District, District of Purbalingga. A survey and purposive sampling techniques were conducted, then the spiders were hand collected. Shannon-Wiener diversity (H’), Evenness (E), Simpson’s dominance (D), and Sorensen’s similarity (IS) indices were used to measure the spider diversity. The results revealed a total number of 575 individual spiders from 10 families, i.e., Araneae, Araneidae, Clubionidae, Linyphiidae, Lycosidae, Nephilidae, Oxyopidae, Salticidae, Tetragnathidae, Theridiidae, and Thomisidae. Araneidae was the most abundant in both fields. The total abundance of spiders in tea plantation (379 individuals), however, was greater than that in the intercropping field (196 individuals). Shannon-Wiener diversity reached H’= 1.873 in the plantation, and H’= 1.975 in the intercropping field.

Abstract

The productivity of strawberry (Fragaria sp.) depends on the presence of pollinator insects that need nectar or pollen as their food. The diversity and the population size of pollinator insects can be increased by the companion planting of Borreria laevicaulis among the strawberry. This research aimed to determine the diversity of pollinator insects of strawberry plantation companion by B. laevicaulis and to determine the relationship between the diversity of pollinator insects with the strawberry fruit produced. This research was conducted in the strawberry plantation of Serang Village, of the District Karangreja, Purbalingga, from June to August 2012. The research was designed to determine the effect of companion planting of B. laevicaulis at the 0%, 5%, 10%, and 15% of the total individuals of strawberry. The results showed that the companion planting of B. laevicaulis in the strawberry field did not affect the species diversity of pollinator insects. But the B. laevicaulis companion planting affected the amount of strawberry yielded. The maximum yield was obtained by planting B. laevicaulis at the 10% of the strawberry individuals; it was increased by 76.12% of the control without companion planting.

Abstract

Butterflies can be classified based on their feed sources into a nectar-feeding and frugivorous butterfly. Frugiforus butterflies are very sensitive to environmental changes. Furthermore, they are easy to be observed by using a simple sampling method. The research on the diversity of frugivorous butterflies was carried out in the rehabilitation zone of the Ciremai Mountain National Park (TNGC) Region Cigugur, Kuningan. The purpose of this study was to obtain information about the diversity of frugivorous butterflies in the rehabilitation zone of TNGC Region Cigugur, Kuningan, as an indicator of land fragmentation and improve the management of TNGC in the use of natural resources, especially for research activities. Butterflies were sampled using a survey method with purposive sampling using bait traps with rotten bananas as bait. Research locations were in the frontier of the rehabilitation area, Cigugur, Kuningan, West Java, perpendicular to the forest frontier along 200 m, which is at a distance of 0-50 m, 50-100 m, 100-150 m, and 150-200 m. The results showed that the diversity of frugivorous butterfly was relatively high with the discovery of 11 types of butterflies from 1 family Nymphalidae.

Abstract

Bombus rufipes Lepeletier 1835 (Hymenoptera: Bombidae) is the only species of Bombidae found in Java. Recent information suggests that it occurs in Java on Mounts Salak 1200 m asl., Mt. Halimun, Mt. Pangrango Gede Complexes, Mt.Cermai, (West Java) Mt.Slamet , Mt. Merapi, Mt. Merbabu, Mt Telomoyo (Central Java) and Mt Argopuro (East Java) , at altitudes above 1,500 m asl. We sought to rediscover this species on Mount Slamet by surveying natural forests at altitudes of 1,500–2,500 m asl on the eastern slopes of Mount Slamet, from August to October 2020 and August to October 2021. Descriptive and morphometric data were obtained and analyzed. The survey revealed five colonies nesting on the ground at an average depth of ca. 70 cm; the colonies contained 18–24 individuals and 22–36 cells (brood, honey, and pollen cells). Based on morphometric measurements and the description of Frison (1930), the species was identified as Bombus rufipes Lepeletier 1835. Therefore, Bombus rufipes still occurs on Mount Slamet. These results provide basic information that should aid further research on this species.

Abstract

In agricultural landscape in northern slope of Mount Slamet, diversity of wild bee species as pollinator depend on forested habitats. This study aimed to assess the effects of distance from the forest edge on the diversity of wild bees on strawberry and tomato crops. This study was conducted from July 2014 to October 2014. The experimental fields contained tomato and strawberry with a total area of 4 ha (2 ha each) and divided into five plots based on distance from the forest edge (0, 50, 100, 150, and 200 m). Wild bee was catched with  kite netting  in 7.00 -9.00 in ten consecutive days. Wild bee diversity differed according to distance from the forest edge, the highest value was at 0 m for strawberry plots (H’ = 2.008, E = 0.72 and Chao1= 16) and for tomato plots, the highest diversity was at 50 m from the forest edge (H’ = 2.298, E = 0.95 and Chao1= 11) and the lowest was at 200 m in both plots. Wild bee species richness and abundance decreased with distance, resulting in the minimum diversity and abundance of wild bee at 200 m from forest edge in both crops. How to CiteWidhiono, I., Sudiana, E.

Abstract

Wild bee pollinators (Hymenoptera : Apiade) diversity and abundance were studied in three types of plantation forest on Mt. Slamet (Central Java Province, Indonesia). The aims of the research was to know the diversity and abundance of wild bee pollinators and to determine the possibility of plantation forest contribution on wild bees conservation. Sampling has been done at three stands: a pine forest (PF, with Pinus merkusii), an Agathis forest (AF, with Agathis damara) and a community forest (CF, with Albizia falctaria). Each habitat was divided into 5 line transect (100 x 5 m) and sweep nets were used to collect the wild bee samples. Sampling was done eah month from April to August 2015. The diversity of wild bees was high (12 species in 9 genera; members of the Apidae (7 species were dominant). The most abundant species across the forests were Apis cerana (343 individuals; 25.5% of total), Trigona laeviceps (195 individuals; 14.5%), and Megachille relativa (165 individuals; 12.3%). Measurements of species diversity (H’), species evenness (E), habitat similarity (Ss) and species richness indicated that the wild bee species diversity in the region was relatively high (H’ = 1.275) to (H’ = 1.730);(E= 0.870) to (E = 0.93). The result showed that the diversity of wild bees in three different plantation forest habitats on Mt. Slamet were similar and can be concluded that plantation forest types were important for pollinator conservation, and an appropriate future preservation strategy should include of the areas of all plantation forest types.
