Abstract

Utami S, Triwidodo H, Pudjianto, Rauf A, Haneda NF. 2018. Population dynamics of Arthroschista hilaralis pest and its parasitoid diversity in various jabon (Anthocephalus cadamba) cropping patterns in South Sumatra, Indonesia. Biodiversitas 19: 239-245. Jabon (Anthocephalus cadamba), a native tree species in Indonesia exhibit natural distribution, spreading over an enormous area in this region. In South Sumatra, jabon has long been cultivated in both communities and industrial plantation forests.  Arthroschista hilaralis (Lepidoptera: Pyralidae) is the most damaging insect pest of jabon in South Sumatra. This study analyzed the population dynamics of A. hilaralis in jabon monoculture and two agroforestry systems, and assessed the diversity of the pest parasitoids and their parasitism level on A. hilaralis. Our results showed that planting systems, climatic factors, and the presence of parasitoids could significantly affect the population dynamics of A. hilaralis; its mean population density was highest in monocultures plantation during the rainy season compared with population densities in agroforestry systems. Three parasitoids species attacking A. hilaralis were found in these agroforestry systems, including Phanerotoma sp.,  Apanteles sp. and Brachymeria sp., while only one species (Apanteles sp.) was found in a monoculture. The rate of parasitization of  A. hilaralis within agroforestry systems was higher than in monocultures, and the level of larval parasitization by Apanteles sp. in the agroforestry system was higher in instar 1 than in other larval stages.

Abstract. Triwidodo H, Listihani. 2020. High impact of PGPR on biostatistic of Aphis craccivora (Hemiptera: Aphididae) on yardlong bean. Biodiversitas 21: 4016-4021. Plant growth-promoting rhizobacteria (PGPR) are root colonizing bacteria that live and develop near plant roots, which boost plant growth and act as antagonist agents. This research is aimed to asses the effect of PGPR on biostatistics of Aphis craccivora Koch on yardlong bean (Vigna unguiculata subsp. sesquipedalis). The research was conducted at WiSH Laboratory in Bogor, Indonesia, by tested PGPR  mixture of Rhizobium, Bacillus polymyxa, and Pseudomonas fluorescens. The research discovered that the application with seed treatment and watered of PGPR affects the biology of Aphis craccivora in terms of lengthening its stadia of second instar nymph, lengthening its life cycle, and declining its fecundity. The application of PGPR also affects the biostatistics of Aphis craccivora. PGPR applied plants have a gross reproduction rate (GRR), net reproduction rate (Ro) and intrinsic increase rate (r) of Aphis craccivora that are lower than control. PGPR could slower the doubled time (DT) of Aphis craccivora to become lengthier than control. PGPR could improve plant growth: it could increase the number and length of roots, number of root nodules, plant height, number of leaves, as well as length and density of trichome.

Abstract. Wiyono S, Istiaji B, Triwidodo H, Suryaningsih AS. 2020. Abundance of soil microbes, endophytic fungi and blast disease of paddy rice with three pest management practices. Biodiversitas 21: 4234-4239. Rice production in Indonesia faces a potential threat of pests and diseases. Biointensive Integrated Pest Management (Bio IPM) is a new approach based on natural and biological control, which effectively controls pests and diseases. However, the impact of this technology on soil microbes and endophytic fungi is almost unknown. The objective of the study was to investigate the effect of Bio IPM on abundance of soil microbes, endophytic fungi, and blast disease under field conditions. Three pest management types were tested i.e. conventional, reduced pesticides, and Bio IPM. Field experiment was set in four replications in randomized complete block design. Experiments were carried out in two seasons i.e. dry and wet season. Variables assessed during experiment were amount of soil bacteria, soil fungi, phosphate solubilizing bacteria, colonization of total leaf endophytes, colonization of Nigrospora sp., and blast disease severity. The results showed that the abundance of soil bacteria and phosphate solubilizing bacteria were significantly increased with Bio IPM whereas it was not found to be significant in soil fungi. Total endophytic fungi and Nigrospora sp. were found higher in Bio IPM especially in early growth stages. Bio IPM controlled neck blast more effectively than conventional and reduced pesticides, but it did not show any significant effect on leaf blast disease.

Abstract. Mulyana AN, Proyambodo S, Triwidodo H, Hendarjanti H, Sahari B. 2020. An assessment of the reproduction, predation, and nesting behavior of Sulawesi Masked-owl (Tyto rosenbergii) in oil palm plantation: A case study of West and Central Sulawesi, Indonesia. Biodiversitas 21: 5685-5689. The quality and quantity of yield in palm plantations are reduced due to inevitable factors such as pests, diseases, and weeds. Furthermore, owls (Tytonidae) play a role as potential predators to control rats, the major pest. Therefore, this study aims to observe the reproduction patterns, predation, and nesting behavior of Tyto rosenbergii. To achieve this, direct observation and the installation of a camera trap in the nest box was adopted. Furthermore, a predation test was carried out by feeding the owls with rats daily in a cage measuring 4m x 8m x 6m. The results showed that the number of eggs produced ranged from 2 to 6, with an average of 3.85. Also, the Percentage of hatching ranges between 0-100% with an average of 80.77%, and that of chicks that survive to the fully feathered is 51%. In addition, T. rosenbergii was able to prey on 1-4 rats per night, and its activity mostly occurs outside the cage than inside, except when they had a reproductive season.

Abstract. Puspasari LT, Buchori D, Ubaidillah R, Triwidodo H, Hidayat P. 2021. Diversity of insect galls associated with Eucalyptus alba & E. urophylla in altitudinal zones in Timor Island, Indonesia. Biodiversitas 22: 2667-2679. We investigated the galling insects associated with two species of Eucalyptus, namely E. alba Reinw. and E. urophylla S.T. Blake in different altitudinal zones in Timor Island, Indonesia. This is the first report for Indonesia of the diversity patterns and community structures of galling insects in these two species of eucalyptus and the type of galls they produce. Surveys and data collection were carried out between October 2017 and June 2018 at different altitudes of secondary forest in Timor Tengah Selatan district, Timor. We visited five altitudinal zones (± 829 m asl., ± 942 m asl. ± 1,621 m asl., ± 1992 m asl., and ± 2457 m asl.) and selected 25 eucalyptus plants of 3 to 5 m in height in each altitudinal zone from which to collect insect galls. The galls were observed on leaves, upper leaves (shoots), outer leaves, symptomatic twigs and stems. The galls were taken to the laboratory for rearing of the insects they contained. A total number of 12 gall types were found in E. alba and 15 in E. urophylla from which 28 insect morphospecies were identified belonging to 16 families and five orders. The order Hymenoptera was represented by ten families: Bethylidae, Torymidae, Eulophidae, Eupelmidae Eurytomidae, Pteromalidae, Encyrtidae, Mymaridae, Braconidae and Scelinonidae while the order Diptera was represented by three families: Fergusoninidae, Cecidomyiidae and Chaoboridae. Galling species diversity ranged from 1.71 to 2.38 on the Shannon-Wiener index and 0.75 to 0.87 on the Simpson index and showed that the galling-insect communities were species-rich and composed of galling formers and very few inquilines. In the study, communities are categorized and structured according to different types of galling insects, including those that induce galling, those that are parasitoid, and those that are inquiline. Within the category of gall-forming insects in the two species of eucalyptus, Eulophidae is found to be the dominant family. Our field data makes an important contribution to basic knowledge of insect galling patterns in eucalyptus forests and constitutes baseline data for the implementation of pest control.

Abstract. Russianzi W, Anwar R, Triwidodo H. 2021. Biostatistics of fall armyworm Spodoptera frugiperda in maize plants in Bogor, West Java, Indonesia. Biodiversitas 22: 3463-3469. Fall Armyworm (FAW) Spodoptera frugiperda (J.E. Smith) is an invasive species that has become important pest of maize in Indonesia since 2019. This research was aimed to study the biology and demographic statistics of FAW in maize at Bogor. Daily observations of 132 FAW individuals from egg to death were carried out as the basis for compiling biology and life table. The demographic statistics of FAW were calculated using the Jackknife approach from the basic life table data. ImagoFAW actives at night. Mating activity occurs between 06.00 pm – 04.00 am, while egg-laying activity occurs between 06.00 pm-10.00 pm. Most hatching occurs between 00.00 am - 02.00 am. FAW has 6 larvae instars and there is no difference in stage between larvae that develop into male and female, which is around 15 days. The male pupae stage was longer than the female pupae, 8.78 ± 0.12 days and 7.81 ± 0.15 days. Male and female imagoes have the same life cycle, which is about 10 days. The life cycle of FAW was 32.26 ± 0.41 days, with a preoviposition period of 2.56 ± 0.45 days. Fecundity of FAW reaches 1012.62 ± 99.12 eggs per female imago. The population of FAW in Bogor has an intrinsic growth rate of 0.154 ± 0.001 individuals/day, with gross reproduction rate of 0.154 ± 0.001 individuals per generation, and net reproduction rate of 104.781 ± 0.155 individuals per imago per generation and a generation time of 30.114 ± 0.002 days.

Abstract. Ananda S, Triwidodo H, Anwar R, Sartiami D. 2024. Rapid assessment of a thrips outbreak on shallots in Brebes and Tegal, Central Java Province, Indonesia. Biodiversitas 25: 5024-5030. One of the high-economic-value crops extensively cultivated by farmers in Indonesia is shallots. The cultivation of shallots often faces problems from plant pests and diseases, which can decrease productivity. One of the pests infesting shallots is thrips. In September 2023, a thrips outbreak was reported in shallot fields in Brebes and Tegal Districts, Central Java Province, Indonesia, causing significant losses for farmers, with severe infestations leading to crop failure. Typically, the beet armyworm Spodoptera exigua (Lepidoptera: Noctuidae) is the primary pest causing significant losses in shallot commodities in Brebes and Tegal. Prior to 2023, thrips were considered secondary pests and rarely caused severe damage. This research aims to investigate the history of thrips infestations based on interviews with 40 farmers, determine the pest population level using pest counts, and identify thrips to species. The research findings indicate that while farmers' knowledge about thrips still needs to improve, there is a significant potential for enhanced thrips management. The farmers’ knowledge, perspective, and actions significantly affect the thrips population in the fields. Farmers in Tegal exhibited more thorough knowledge of thrips management than those in Brebes, where thrips populations were higher. Climatic factors, such as increased temperatures and decreased rainfall, contributed to the rise in the thrips population. Farmers' adaptation strategies to cope with thrips outbreaks include increasing the frequency and dosage of pesticide spraying, early harvesting, and abandoning infested fields, which results in crop failure. The thrips species causing shallot damage in Brebes and Tegal was Thrips tabaci (Thysanoptera: Thripidae).

Abstract

Desa Sempu, Kecamatan Ngancar, Kabupaten Kediri adalah salah satu desa yang mayoritas penduduknya bergantung pada sektor pertanian sebagai sumber penghidupan utama. Program pengabdian masyarakat ini bertujuan meningkatkan pengetahuan petani, membentuk sikap dan perilaku yang mendukung penerapan pengendalian hama terpadu serta memanfaatkan platform Digitani sebagai sarana informasi dan panduan teknis. Metode pelaksanaan menggunakan pendekatan ceramah, diskusi interaktif, dan tanya jawab secara luring maupun daring. Kegiatan pengabdian dilaksanakan pada tanggal 18 Juni–9 Agustus 2025 melibatkan 45 peserta yang terdiri dari masyarakat dan kelompok tani Desa Sempu. Hasil diskusi menunjukkan masalah utama yang dihadapi, yaitu serangan penyakit dan hama pada komoditas unggulan, yakni nanas, cabai, dan tomat. Selain itu, penggunaan pestisida tanpa panduan teknis, ketiadaan rotasi bahan aktif, serta ketidakakuratan identifikasi organisme pengganggu tanaman. Melalui program penyuluhan pengabdian ini, petani memperoleh pengetahuan tentang identifikasi hama dan penyakit, penggunaan pestisida yang tepat, pemanfaatan agens hayati, dan teknologi digital untuk konsultasi pertanian. Output yang diperoleh, yaitu adanya peningkatan minimal 50% pengetahuan, kemandirian petani, dan produktivitas pertanian masyarakat di Desa Sempu yang mendukung ketahanan pangan lokal. Hal tersebut dapat dilihat dari terbentuknya kebiasaan baru untuk rotasi bahan aktif, melakukan konsultasi berbasis Digitani, dan berkurangnya aplikasi pestisida kombinasi yang berisiko.
