Background: Stingless bees is one group of eusocial insects living together in the hive. There are around 46 species of stingless bee in Indonesia with different morphological, morphometric and hive structure characteristics. This study aimed to describe the morphological, morphometric and beehives structure of Tetragonula laeviceps from Yogyakarta. Methods: Survey method is used by taking three sampling points of bamboo, house building and livestock crates in Bantul Regency. Sampling points determined by Purposive sampling method. An XSZ-107 BN binocular microscope analyzed samples of T. laeviceps with Optilab viewer and Image Raster software. Results: The results showed morphological characters of T. laeviceps are dominated shiny-black body, brownish-yellow antennas, klipeus on a head covered by fine silver hair, brownish-yellow mandible with two teeth, mesonotum in thorax covered by brownish to black hair, scutellum extended to propodeum, the ribbon of hair on the dorsal thorax is not very clear, and the hind tibia is rather hairy. Morphometric of T. laeviceps included body length between 3.44 - 3.76 mm, head width 1.55 - 1.70 mm, front wing length with tegula 3.76 - 4.37 mm, length of rear limbs tibia 1.37-1.57 mm, and the number of hamuli as many as 5. The beehive structure consisted of oval-shaped entrance formed funnel and varying internal hive in terms of the number of saplings, pollen cells, and honey cells. Conclusions: T. laeviceps have morphological, morphometric and hive structure characteristics that are different from other species and variated compared to similar species from other regions.
Orchidaceae merupakan kelompok tumbuhan berbunga yang memiliki struktur unik, serta bentuk bunga yang sangat beragam, hal ini dapat mempengaruhi jenis serangga pengunjung. Penelitian ini bertujuan untuk mengetahui jenis serangga yang berkunjung pada bunga anggrek baik di dalam maupun diluar green house, khususnya spesies bunga anggrek Vanda tricolor. Penelitian ini dilaksanakan pada bulan November 2019. Pengamatan jenis serangga pengunjung pada jenis bunga anggrek dilakukan dengan metode scan sampling. Serangga pengunjung bunga Vanda tricolor di luar green house yaitu genus Crematogaster (anggota Ordo Hymenoptera: Familia Formicida), Anoplolepis (Hymenoptera: Formicidae), Xylocopa (Hymenoptera: Formicidae), Vespa (Hymenoptera: Formicidae), Drosophila (Diptera: Drosophilidae), Stomorhina (Diptera: Calliphoridae), Lucilia (Diptera: Calliphoridae), Chrysomya (Diptera: Calliphoridae), Musca (Diptera: Muscidae), Camptomyia (Diptera: Cecidomyiidae), Orchestes (Coleoptera: Curculionidae), Carpophilus (Coleoptera: Nititulidae), Stagmomantis (Mantodea: Mantiae) dan Ligocoris (Hemiptera: Miridae). Dari ke dua belas genus yang ditemukan mengunjungi bunga anggrek di luar green house, diketahui bahwa kedua genus yaitu Aphaenogaster dan Anoplolepis juga ditemukan mengunjungi bunga Vanda tricolor yang berada di dalam green house.
Hymenoptera is one Order of insect which helpful for plant pollination, produces honey and wax, also can eliminate pests, one of which is in cowpea plants. This study aims to determine the diversity of Hymenoptera insects in cowpea (Vigna sinensis L.) agricultural area at Martapura District, Banjar Regency, South Kalimantan. Hymenoptera insect collection is carried out in the villages of Bincau, Labuan Tabu and Indra Sari with two kinds of methods, namely swep net during the day and light trap at night. The results showed that the cowpea agricultural area in Labuan Tabu village had the highest diversity value with a value of H '= 2.58, while the lowest value of H' was 2.28 in Indra Sari Village.
Lalat merupakan jenis serangga yang hidup dekat dengan lingkungan manusia. Jenis lalat yang berada di sekitar permukiman sangat banyak dan membawa berbagai jenis penyakit yang dapat membahayakan kesehatan masyarakat. Penelitian bertujuan untuk menentukan kelimpahan nisbi, frekuensi, dan dominansi jenis lalat di beberapa pasar tradisional di Kecamatan Martapura. Penelitian dilakukan di lima pasar tradisional yaitu Pasar Sejumput, Pasar Batuah, Pasar Sekumpul, Pasar Permata, dan Pasar Kuliner pada bulan April sampai Mei 2020. Koleksi lalat menggunakan sweep net dengan cara mengayunkannya di sekitar tempat sampah. Lalat yang telah dikoleksi kemudian diidentifikasi dengan menggunakan kunci identifikasi. Hasil penelitian menunjukkan bahwa terdapat empat spesies lalat dalam lokasi penelitian yaitu Musca domestica, M. conducens, Chrysomya megacephala dan C. rufifacies. Kelimpahan nisbi, frekuensi spesies dan dominansi spesies menunjukan bahwa tertangkapnya lalat M. domestica lebih tinggi dibandingkan spesies lainnya. Selanjutnya, Pasar Batuah merupakan lokasi penelitian dengan jumlah kelimpahan nisbi, frekuensi spesies, dan dominansi spesies lalat terbanyak jika dibandingkan lokasi Pasar Tradisional lainnya. Penelitian ini bermanfaat sebagai informasi awal dalam menentukan potensi lalat sebagai vektor penularan penyakit disuatu lingkungan. Kata kunci: kelimpahan nisbi, frekuensi, dominansi, jenis lalat, pasar tradisional
