Abstract

Root-lesion and root-knot nematodes are amongst the most important pathogens of coffee and can cause substantial yield losses and quality reductions. Environmental and health concerns concerning the use of chemical pesticides have increased the need for alternative management strategies against plant-parasitic nematodes. The aim of our study was to isolate and identify nematophagous fungi from nematode-infested coffee production areas and evaluate their potential as biocontrol agents. Our study was carried out in two stages: 1) fungi isolation and evaluation of their ability to affect eggs or vermiform developmental stages of root-lesion and root-knot nematodes; 2) identification of fungal isolates to species level. Eleven fungal isolates were able to affect either the nematode eggs or the vermiform developmental stages. The ability of these fungi to produce extracellular enzymes were also evaluated. This study highlights Indonesian nematode infected coffee rhizosphere soils as a rich source of nematophagous fungi, with eleven isolates showing promises to be used for integrated pest management strategies. Future work should assess field efficacy under local conditions while monitoring impacts on soil food webs and non-target organisms.

Oktriani R, Kurniasari I, Candrasari DS, Hidayati L, Handayaningsih AE, Probowati VC, Arianto B, Wardana DS, Pramuko NB, Utari A, Tantowijoyo W, Arguni E. 2020. Wolbachia infection prevalence as common insects’ endosymbiont in the rural area of Yogyakarta, Indonesia. Biodiversitas 21: 5608-5614. Control for mosquito-borne diseases such as dengue and chikungunya using vectors is urgently required. The World Mosquito Program, a multinational collaborative research program, is currently studying for the ability of Wolbachia-infected Aedes aegypti to control dengue. Community concerns on Wolbachia's natural existence in their surrounding living area. This study presents the field study of Wolbachia pipientis in insects commonly found in rural daily life. W. pipientis is an endosymbiotic bacterium commonly found in arthropods. Insects were collected from five villages in Sleman and Bantul District, Yogyakarta Province, Indonesia, from July to December 2012 and screened for Wolbachia infection using PCR. One hundred insects, including butterflies, moths, mosquitoes, flies, were collected. The results indicated that 44.9% of identified insect species were positive for Wolbachia pipientis, which support the existing data from other regions on the spread of Wolbachia infection in insects.

Abstract. Rovik A, Daniwijaya EW, Supriyati E, Rahayu A, Kumalawati DA, Saraswati U, Handayaningsih AE, Rachman MP, Oktriani R, Kurniasari I, Candrasari DS, Nurhayati I, Sholeh R, Arianto B, Tantowijoyo W, Ahmad RA, Utarini A, Arguni E. 2022. Wolbachia genetic similarity in different insect host species: Drosophila melanogaster and Yogyakarta’s (Indonesia) Aedes aegypti as a novel host. Biodiversitas 23: 2321-2328. Wolbachia naturally presents in a large number of insects and other arthropod species. The Wolbachia strain wMel from Drosophila melanogaster has been stably transinfected into Aedes aegypti where it stops the mosquito host from being infected with medically important arbovirus like dengue. Consequently, Ae. aegypti infected with wMel have been released in Indonesia as a public health intervention against dengue. This study genetically compared wMel from Yogya field-caught D. melanogaster and the wMel in stably transfected Ae. aegypti used for field releases in Yogyakarta, Indonesia. The genetic similarity between wMel Wolbachia was evaluated by sequencing of Wolbachia surface protein (wsp) gene and some polymorphic genomic regions of insertion sites (IS) and variable number tandem repeats (VNTR) loci. The sequence of the Wolbachia surface protein (wsp) gene was 100% identical between hosts. There is no insertion sequence among specimens. The insertion sequence IS-WD1310 was identical between wMel from both hosts and among other strains, as well as the IS-WD516/7. The VNTR-141 period was identical within wMel from both hosts and among other strains, the VNTR-105 as well. Wolbachia Yogya field-caught D. melanogaster and Wolbachia strain wMel present in Ae. aegypti used for bio-control of dengue were genetically identical. These findings provide beneficial understanding to answer the public attention on safety issues, especially on the genetic similarity between Wolbachia strain in the natural and transfected hosts of this novel technology for dengue control.

Abstract. Kurniasari I, Wibowo A, Subandiyah S, Pattison AB. 2024. Association of soil bacterial diversity and composition with Fusarium wilt disease of bananas in Yogyakarta Province, Indonesia. Biodiversitas 25: 2264-2275. Infection of banana plants with Fusarium oxysporum f. sp. cubense Tropical Race 4 (Foc-TR4) leads to a cascade of changes in the rhizosphere, resulting in changes to the soil physicochemical properties and bacterial community composition. This study aimed to determine the core taxa associated with different soil physicochemical properties and disease statuses and to identify the factors exerting the greatest influence on the soil bacterial community composition of bananas in Special Region of Yogyakarta Province, Indonesia. Rhizospheric soil from healthy and infected plants was collected from four banana locations, including Kulon Progo, Gunungkidul, Bantul, and Sleman districts, at 10-30 cm depth between May and September 2021. Laboratory analysis was conducted for soil physicochemical properties, and the abundance of Foc-TR4 was undertaken. Additionally, 16S rRNA gene-based metagenomics analysis was used to quantify bacterial diversity in all samples. Soil type significantly influenced the abundance and composition of the bacterial community more than disease status did. Contrarily, disease status groups influenced the complexity of bacterial network interaction more than soil type. Actinobacteriota, Proteobacteria, Chloroflexi, Acidobacteriota, and Bacteriodota are the major phyla associated with all soils. This study identified 60 bacterial genera as core members of the banana rhizosphere. These core bacterial genera include various plant growth-promoting bacteria involved in nitrogen fixation, phytohormone production, siderophore production, and biocontrol mechanisms for producing antifungal compounds. Our work provides a basis for future research on the soil bacterial composition associated with banana plants to enhance plant health against Fusarium wilt disease.
