Indonesia with high mosquito species diversity faces the problem related to the presence of several important vector-borne diseases, including malaria, chikungunya, dengue fever, filariasis, and Japanese encephalitis. Updated key to the mosquitoes is needed to provide up to date information of the appropriate disease vectors in Indonesia. Currently, before the publication of the checklist of Indonesian mosquitoes by O’Connor &amp; Sopa (1981), there has been no recent information on the number of mosquito genera and subgenera in Indonesia. This article aims to deliver updates on mosquito taxonomic information and provide the identification key of the mosquito genera in Indonesia. So far, a total of 21 genera and 63 mosquito subgenera has been reported in this country. Overall there are three genera and 15 subgenera added from the 1981’s mosquito checklist, <em>Verrallina</em>, <em>Lutzia</em>, and <em>Kimia</em> are added in the list of new mosquito genera.</p> Sidiq Setyo Nugroho, Mujiyono Mujiyono Copyright (c) 2020 Jurnal Entomologi Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/595 Mon, 07 Jun 2021 00:00:00 +0000 Kondisi habitat dan keberadaan tropobion memengaruhi keanekaragaman dan kelimpahan semut di perkebunan kakao http://jurnal.pei-pusat.org/index.php/jei/article/view/649 <p>Habitat conditions around cocoa plantations which include canopy cover and lower vegetation (weeds) as well as the presence of mealybugs trophobiont (<em>Planococcus</em> sp.) can affect the diversity and abundance of ants. The objective of this research was to study the diversity and abundance of ants in cocoa plantations and to study the effect of habitat conditions and the presence of trophobiont (<em>Planococcu</em>s sp.) on species richness and ant abundance. The research was carried out in 12 locations spread across five districts in East Java. Ant samples were collected by tuna bait and direct collection. The results obtained 5,475 individuals and 8 species of ants. The most dominant ants and found in all areas were <em>Dolichoderus thoracicus</em> (Smith) and <em>Technomyrmex albipes </em>(Smith). Based on the regression analysis, there is a relationship between canopy cover and vegetation diversity with ant species, but not with abundance, meanwhile the presence of trophobiont shows a positive correlation with ant abundance. The habitat conditions for cocoa cultivation and the presence of trophobiont affect the diversity and abundance of ants in cocoa plantations.</p> Novita - Yuniasari, Nely - Yuliastanti, Toto - Himawan, Akhmad - Rizali Copyright (c) 2021 Jurnal Entomologi Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/649 Mon, 07 Jun 2021 00:00:00 +0000 Morfologi dan variasi morfometrik lebah tanpa sengat di Kepulauan Maluku, Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/617 <p>Stingless bees are widely distributed in tropical regions including Indonesia, and currently three species of stingless bee have been recorded in the Moluccas. The aims of this study were to explore the species and distribution of stingless bees in the five islands in the Moluccas (Seram, Ambon, Haruku, Saparua, and Nusalaut island) and compare the morphometric variations of stingless bees within and among islands. The samples of stingless bees were identified based on twelve morphological characters, resulting in two species of <em>Tetragonula fuscobalteata</em> (Cameron) and <em>T. sapiens</em>. (Cockerell). <em>T. fuscobalteata </em>found to be a new record in the Moluccas<em>, </em>and showed significantly lower morphometric parameters compared to those of <em>T. sapiens </em>(P &lt; 0.001). Based on non-metric multidimensional scaling (NMDS) analysis, the combination of twelve morphometric parameters between <em>T.</em> <em>fuscobalteata</em> and <em>T. sapiens </em>were significantly different. Almost all morphometric parameters of <em>T. fuscobalteata</em> showed highly varied among islands, except the width of gena of this stingless bees. <em>T. fuscobalteata</em> from Ambon, Haruku, Saparua, and Nusalaut were mostly clustered based on NMDS analysis, while those from Seram show high variations. This study found <em>T. sapiens </em>in three different islands, Seram, Ambon, and Haruku. Width of thorax, mesonotum, and propodeum length of <em>T. sapiens </em>were significantly different among these three islands (P &lt; 0.001). This study has contributed to the new distribution data of <em>T. fuscobalteata</em> and <em>T. sapiens </em>in the Moluccas and showed variation of morphometric parameters of the two stingless bee species among islands in the Moluccas.</p> Yofian Anaktototy, Windra Priawandiputra, Tiara Sayusti, Jacobus SA Lamerkabel, Rika Raffiudin Copyright (c) 2021 Jurnal Entomologi Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/617 Mon, 07 Jun 2021 00:00:00 +0000 Keanekaragaman dan kelimpahan kumbang cerambycid (Coleoptera: Cerambycidae) di Cagar Alam Pangandaran, Jawa Barat http://jurnal.pei-pusat.org/index.php/jei/article/view/628 <p>The community structure of cerambycid beetles in an area is closely related to the heterogeneity of woody plants. Pangandaran Nature Reserve is forest located in the peninsula and has unique fauna and flora communities. The study aims to analyze the diversity and abundance of cerambycid beetles in the Pangandaran Nature Reserve. To attract the cerambycid beetles, we used branches of jackfruit (<em>Artocarpus heterophyllus</em>) and fig (<em>Ficus septica</em>) as traps. Traps were tied in a tree or log about 1.5 m from the ground in the Nature Recreation Park and the Nature Reserve, each area with 2 locations. Collection of beetles were carried out by beating method. A total of 574 individuals cerambycid beetles were found, belonging to 1 subfamily, 8 tribes, 12 genera, and 20 species. The highest species diversity of beetles was found in Nature Recreation Park-1 (H’ = 2.09, E = 0.74), followed by Nature Reserve-2 (H’ = 1.75, E = 0.68), Nature Recreation Park-2 (H’ = 1.70, E = 0.71), and Nature Reserve-1 (H’ = 1.52, E = 0.69). Four species of beetles found in high abundance were <em>Sybra binotata</em> Gahan (229 individuals), <em>Nyctimenius javanus</em> (74 individuals), <em>Atimura bacillina</em> Pascoe (67 individuals), and <em>Acalolepta rusticatrix </em>(Fabricius) (45 individuals). The number of individual beetles collected in <em>Artocarpus </em>(342 individuals) was higher than <em>Ficus</em> traps (232 individuals). This study identified seven endemic beetles of Java, i.e., <em>Myagrus javanicus </em>Breuning, <em>Cacia curta </em>Breuning, <em>Sybra obliquefasciata </em>Breuning, <em>Sybra fuscotriangularis </em>Breuning, <em>Pterolophia triangularis </em>Breuning, <em>N.</em> <em>javanus</em>, and <em>Exocentrus artocarpi </em>Fisher.</p> Septiani Dewi Ariska, Tri Atmowidi, Woro Anggraitoningsih Noerdjito Copyright (c) 2021 Jurnal Entomologi Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/628 Mon, 07 Jun 2021 00:00:00 +0000 Statistik demografi kumbang predator Stethorus punctillum Weise (Coleoptera: Coccinellidae) pada Tetranychus kanzawai Kishida (Acari: Tetranychidae) http://jurnal.pei-pusat.org/index.php/jei/article/view/583 <p><em>Tetranychus kanzawai</em> is a species of mite that can cause agricultural crop losses of about 60–90%. One way to control pests that are environmental friendly is to use the predatory beetle <em>Stethorus</em> <em>punctillum</em>. This study aims to determine the demographic statistics, preferences, and functional response of <em>S.</em> <em>punctillum</em> on <em>T. kanzawai</em>. Observation of the <em>S. punctillum</em> biological using 100 eggs, observations were made of the number of individuals living until adult females produce offspring. Preferences of <em>S.</em> <em>punctillum</em> using 50 eggs and 50 nymphs and <em>T. kanzawai</em> adults, observations were made on the number of <em>T. kanzawai</em> preyed by instar larvae I, II, III, IV, and <em>S.</em> <em>punctillum</em> adults. Functional response is done by giving <em>S.</em> <em>punctillum</em> prey as many as 30, 40, 50, 60, 70, 80 eggs <em>T. kanzawai</em>, observations made on the remaining number of eggs. <em>S. punctillum</em> eggs last for 7.01 ± 0.72 days. First instar larvae lasted for 4.84 ± 0.51 days, second instar 3.16 ± 0.52 days, third instar 3.00 ± 0.27 days, and IV instar 2.48 ± 0.50 days. Females lay eggs 64.47 ± 2.37 eggs. Gross reproduction rate (GRR) of <em>S. punctillum</em> 64.29 individuals/generation, net reproduction rate (Ro) of 17.18 individuals/female/generation, intrinsic accretion rate (r) of 0.27 individuals/female/day, average the generation period (T) is 62.41 days, and the double time (DT) is 2.51 days. The data shows that <em>S. punctillum</em> has a preference for <em>T. kanzawai</em> egg stages and type III functional response curves with Th 7.68 minutes and a 0.22 eggs/minute.</p> Sugeng Santoso, Nirma Septia Ramlan Anjas, Ali Nurmansyah Copyright (c) 2021 Jurnal Entomologi Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/583 Mon, 07 Jun 2021 00:00:00 +0000 Hubungan antara struktur lanskap dan keanekaragaman Hymenoptera parasitoid: Sebuah model interaksi pada pertanaman kacang panjang http://jurnal.pei-pusat.org/index.php/jei/article/view/557 <p>Landscape structure and composition are an important part of a landscape’s character which can affect the presence of predators and parasitoids, and influence the effectiveness of biological control. This study aims to examine the relationship between landscape features and the diversity of Hymenoptera parasitoids using long bean plants as a model. Sampling was conducted in a 50 m x 25 m plots. In each plot, 4 transects, each 50 m in length, were used to sample insects. Insects were collected using yellow pan traps, malaise traps, and direct hand collections. Overall, a total of 4.792 individuals of Hymenoptera parasitoids were collected, which consisted of 28 families and 256 species. Results showed that landscape characteristics influence the diversity, abundance, and evenness index. Diversity index and evenness are higher in landscape that is dominated by agricultural class area. The abundance of Hymenoptera parasitoid was higher in the landscape that is characterized by tree class areas compared to the agricultural class area.</p> Tazkiyatul Syahidah, Lilik Budi Prasetyo, Pudjianto, Damayanti Buchori Copyright (c) 2021 Jurnal Entomologi Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/557 Mon, 07 Jun 2021 00:00:00 +0000 MtCOI DNA sequences from Sycanus aurantiacus (Hemiptera: Heteroptera: Reduviidae) provide evidence of a possible new harpactorine species from Bali, Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/574 <p><em>Sycanus aurantiacus </em>Ishikawa &amp; Okajima, found in Bali, was first described in 2007 as a new harpactorine species based on morphological and biological characteristics; however, its genome has not yet been sequenced. In this study, we examine the mitochondrial cytochrome oxidase subunit I (MtCOI) nucleotide sequence of <em>S. aurantiacus </em>in order to determine whether it represents a new harpactorine species. A sample from Pancasari, Bali, Indonesia was collected at the same location <em>S. aurantiacus </em>was first discovered in 2007<em>. </em>The selected mtCOI gene (650 bp) was successfully amplified using mtCOI primer pairs LCO1490 and HCO2198, and the resulting MtCOI sequence of the <em>S. aurantiacus</em> sample was compared with those from other hapactorine species recorded in GenBank. This comparison revealed low genetic similarity between <em>S. aurantiacus</em> and most other harpactorine species worldwide, except for the Genus <em>Sycanus </em>(JQ888697) from USA whose mtCOI shares approximately 91% similarity with the Pancasari sample. Phylogenetic analysis indicated a close genetic relationship between <em>Sycanus </em>from Bali and the Genus <em>Sycanus </em>(JQ888697) from the USA. The mtCOI sequence of <em>S. aurantiacus</em> had not been recorded previously, and our comparison with existing Sycanus sequences provides support to the understanding that <em>S. aurantiacus</em> is indeed its own species.</p> I Putu Sudiarta, Dewa Gede Wiryangga Selangga, Gusti Ngurah Alit Susanta Wirya, Ketut Ayu Yuliadhi, I Wayan Susila, Ketut Sumiartha Copyright (c) 2021 Jurnal Entomologi Indonesia http://jurnal.pei-pusat.org/index.php/jei/article/view/574 Mon, 07 Jun 2021 00:00:00 +0000
