Sub-districts Kie and Fatumnasi are two sub-districts in mainland West Timor that cultivate local potatoes from Soe. This germplasm needs to be preserved and developed to diversify non-rice alternative food. One of the main obstacles in cultivating potatoes is the presence of pests, but so far there have been no reports of pests on local potato plants from Soe from the two sub-districts, so this research needs to be done. This study aimed at an inventory of important pests on local potato plants from Soe as a database for early detection to prevent the occurrence of explosive pests. This research was conducted on potato plantations in Fatuulan Village, Ayofanu Village, Nunleu Village, and Nenas Village. The method used is a purpose survey at a specified sample point. A sampling of insect pests is done by direct observation and insect nets. The pests found were put in a killing bottle or 70% alcohol, collected, and identified. Observation variables include the type of pest, symptoms of pest attack, and morphological characteristics of the stadia found. The data obtained were analyzed descriptively. The results showed that five species of pests damaged local potatoes from Soe. The five pests were Spodoptera litura, Henosepilachna vigintioctomaculata, Liriomyza sp, Phthorimaea operculella, and Nezara viridula. The identification results showed that in Kie District there were three pest species, namely S. litura, H. vigintioctomaculata, and Liriomyza sp. Meanwhile, in Fatumnasi District, there were four types of pests, namely H. vigintioctomaculata, Liriomyza sp, P. operculella, and N. viridula

“…RKN infestation in potato soil in Sumatera and Java far exceeded this threshold, but the nematode effect on potato yield reduction was not obvious (Hadisoeganda, 2006b). As much as 114 J2/100 g soil or 2-675 cysts/100 g soil of PCN were reported (Hadisoeganda, 2006b;Lisnawita et al, 2012;Nugrahana et al, 2017;Syafi'i et al, 2018). At 100 J2/100 g soil, PCN can cause 11% potato yield loss in Western Europe (Hadisoeganda, 2006a).…”

The plant-parasitic nematode (PPN) is often not recognized as important limiting crop production in Indonesia. This is largely caused by non-specific and non-dramatic above-ground plant disease symptoms, their microscopic nature, and partly caused by inadequate demonstration of the economic importance of this hidden pathogen. However, change in agricultural practices to meet the ever-increasing food demand along with global climate change may increase the risk of PPNs on crop productivity in the future. This paper reviews PPN inventory in Indonesia during the last three decades. Thirty-three genera of PPNs were found to associate with 25 host plants. Some genera were present at the densities that are considered as damaging levels in other countries. Results among surveys are difficult to compare because of differences in crop cultivar surveyed, cultivation practices, sampling unit and method, and nematode extraction techniques. Lack of field supporting data did not permit a valid assessment of nematode risk on a particular crop. The first record of several quarantined species has been reported, but not all of them have been validated molecularly. Challenges and opportunities to improve the future field survey are presented in this paper.

“…The presence of PPNs on potato plants in Indonesia has been documented in some prior studies; these studies indicated that major potato-growing regions across the country, including Wonosobo, Batu City, and several locations in West Java, were all likely to be infected by nematodes (Aprilyani et al 2015;Syafii et al 2018). However, in Indonesia, the diversity of PPNs that infect potato plants and their diversity at various altitudes still needs further study.…”

Abstract. Prada AP, Pratiwi GNC, Wagiyana. 2022. Diversity of plant-parasitic nematodes in potato fields at different altitudes in Probolinggo District, East Java, Indonesia. Cell Biol Dev 6: 61-67. Plant parasitic nematodes (PPNs) are microorganisms sensitive to environmental conditions. Therefore, plant parasitic nematode diversity in a field may affect the decision of effective management tactics. This study aimed to assess the diversity of plant parasitic nematodes in potato fields at three different altitudes. The study was carried out in Probolinggo District, East Java, Indonesia. The sampling area was divided into three groups based on altitude variations, namely 1,008 m asl., 1,413 m asl., and 1,875 m asl. Soil samples were collected randomly in a zigzag pattern. Samples were collected from 20 points across each field at a depth of 20-30 cm below the soil surface. Each sub-sample included up to 500 g of soil. The white head tray method extracted nematodes from 500 g of soil from each subsample. After characterizing the extracted nematodes, the absolute density and dominance values were determined. The results revealed variations in the three areas with different altitudes. The total number of plant-parasitic nematodes (PPN) discovered on the field at an altitude of 1,008 m asl. was 57.00 ± 16.43. Furthermore, at an altitude of 1,413 m asl., the total number of PPNs discovered is 41.67 ± 10.98. The total number of nematodes on the field at an altitude of 1,875 m asl. was 50.50 ± 12.60. The findings of this study also indicated that Meloidogyne sp. was the genus with the highest population on the field, at an altitude of 1,008 m asl. On the other hand, Pratylenchus sp. is the most abundant nematode in the field between 1,413 and 1,875 m asl. An identical situation also occurred with the nematode dominance values in the three fields studied.
