Mutala’liah, Indarti S, Putra NS. 2018. Abundance and diversity of plant parasitic nematodes associated with BP 308 and BP 42 clones of robusta coffee in Java, Indonesia. Biodiversitas 19: 67-70. Plant parasitic nematodes are an important limiting factor in the productivity of coffee plantations. Clone resistance and soil texture influence the severity of plant infestation by parasitic nematodes. The aim of this research was to determine the diversity of plant parasitic nematodes in two clone of Robusta coffee (BP 308 and BP 42) on soils with different contents of sand. The research was carried out in Malangsari Field (East Java), Getas Field (Central Java) and Candiroto Field (Central Java). Nematodes were extracted from soil samples by the decanting method using a whitehead tray, while roots sample by the funnel spray method with a ‘mistifier’. Differences in diversity of nematode genera between clone and location combinations were analyzed by ANOVA. The results showed that there were five genera associated with Robusta coffee, i.e. Pratylenchus, Helicotylenchus, Radopholus, Rotylenchulus, and Meloidogyne. With clone BP 308 at the Malangsari Field site where soil contained 31.3 % sand, Pratylenchus was the most abundant genus i.e. 6 nematodes/100 mL soil. On the same clone, BP 308, at the Getas Field site where soil contained 26.9 % sand, Meloidogyne was the most abundant i.e. 14.4 nematodes/10 g roots. With clone BP 42 at the Candiroto Field site with 25.5 % sand in the soil, Pratylenchus was highly abundant i.e. 60 nematodes/10 g roots.

Abstract. Tarno H, Marsudi EW, Widjayanti T, Setiawan Y. 2021. Short Communication: Nematodes associated with Robusta coffee plantations in Malang District, East Java, Indonesia. Biodiversitas 22: 3306-3312. Coffee (Coffea spp.) is an important commodity in Indonesia. Nematodes have different roles, such as plant parasites and non-parasites, and are commonly found in the soil of coffee plantations. This research determined the ecological role, diversity, and abundance of nematodes in three coffee plantations in Malang District, East Java. We used a Whitehead tray to extract and isolate nematodes from the soil and root samples. Nematodes were identified based on their morphological characteristics. Analysis of variance and diversity indices were used to identify the differences among three coffee plantations. We identified eight nematode genera in the Ngantang sub-district site. In the Jatikerto Agrotechnopark and University of Brawijaya Forest sites, six genera were identified. Criconemoides, Pratylenchus, Xiphinema, Helicotylenchus are plant-parasitic nematodes, and Mononchus, Dorylaimus, Rhabditis, and Aphanolaimus are non-plant parasitic nematodes. Non-plant parasitic nematodes were more abundant than plant-parasitic nematodes in all sites. Non-plant parasitic nematode, Dorylaimus was the dominant genus in this study (272 individuals), ca. 35% of the total nematodes collected. In this study, the differences between coffee plantations and soil pH influence nematode abundance. The nematode abundance increases when the soil pH is lower.

ABSTRACTCharacteristic of  Nematodes Community at PGS Golf Course Bandar Lampung. Golf course is a unique ecosystem where plant parasitic nematodes inhabit and become  important pest because they reduce the quality of the grass.  The pest problems on golf course can be indicated by its characteristics of nematode community.  Survey on nematodes community at PGS Golf Course Bandar Lampung was conducted from March to December 2004.  The objective was to study the characteristics of nematode community in the part of golf courses hole (green, collar, apron, and fairway).  Soil samples were taken from five holes each of it consists of green, collar, apron, and fairway, respectiveley.  Nematodes extraction was done in Laboratory of Arthropod Pest, Department of Plant Protection University of Lampung.   The result showed that at least 50 nematodes genera of 28 families inhabit PGS. The number of plant parasitic nematode genera was higher than the free-living one.  The characteristic of nematodes community on green and collar was different than on faiway. Nematode abundance and diversity on green and collar were higher than on fairway.  Based on abundance of nematode feeding group, maturity index of free-living nematodes (MI) and that of plant parasitic nematodes (PPI), green and collar part seemed to be more favorable to plant parasitic nematodes than free-living nematodes. The contrary happened for fairway.  Four most dominant genera of plant parasitic nematodes on PGS golf course were Helicotylenchus, Hoplolaimus, Criconemella, and Xiphinema.

Plant-parasitic nematodes (PPNs) contribute to yield losses in pineapple production. Limited studies have been conducted on plant-parasitic nematodes on pineapple despite reports of PPNs infecting it. A survey was conducted in Obio-Akpor and Ikwerre Local Government Areas (LGAs) of Rivers State to determine the occurrence, abundance and diversity of PPNs associated with pineapple. A total of 60 composite samples were collected from the two LGAs. Nematodes were extracted from soil and root samples using the modified Baermann technique and identified using standard procedures. Data were processed using relative frequency of occurrence (RFOC), relative importance values (RIVs), diversity indices, nematode population was calculated and analysis of variance. The most occurring plant-parasitic nematodes were Pratylenchus, Helicotylenchus, Meloidogyne, Scutellonema and Tylenchulus. In Obio Akpor LGA, Helicotylenchus with RFOC 33.3% was the most occurring nematode pests, while Pratylenchus was the most important plant-parasitic nematode (RIV 33.8%). In Ikwerre LGA, both Helicotylenchus and Pratylenchus have the same occurrence (RFOC 33.3%) with Pratylenchus being the most important nematode pest. Pratylenchus species with RIV of 52.4% were the most important PPNs associated with pineapple in both Obio-Akpor and Ikwerre LGAs. Dominance and Shannon- Weiner indices among the PPNs are 0.58 and 0.86, respectively. In Ikwerre and Obio-Akpor LGAs, Aluu (1530) and Rumuekini (630) pineapple farms have the highest population of PPNs, respectively. Ikwerre LGA (2,150) pineapple farms had more PPNs than Obio-Akpor LGA (660). Nematode pests are associated with pineapple in the two LGAs and could be contributing to yield losses.

Summary Little information is available for nematode pests associated with watermelon in sub-Saharan Africa (SSA). This study recorded the abundance and prevalence of plant-parasitic nematodes from 25 localities across south-west Nigeria during 2016/2017. Of the 11 nematode species identified, those belonging to Meloidogyne spp. were predominant according to Prominence Values, followed by Helicotylenchus dihystera, Pratylenchus zeae and Scutellonema bradys. Morphological and molecular analyses revealed the identity of four species of root-knot nematodes: Meloidogyne enterolobii, M. incognita, M. javanica and M. arenaria (in descending order of abundance and occurrence). Meloidogyne arenaria is reported for the first time from south-west Nigeria, while S. bradys and Xiphinema nigeriense are first reports for watermelon. Significant associations were observed between the frequency of occurrence of the predominant nematode species and soil properties as well as rainfall. Results provide baseline information on the nematode pest occurrence on watermelon in Nigeria and in a wider context for SSA.

Parasitism is an important limiting factor responsible to cause damage to agricultural production. Plant parasitic root knot nematodes attack several economic crops in Pakistan. Plant- parasitic nematodes considerably add huge losses to economies in the top tomatoes crop producing countries throughout the world, instead of controlling the main pathogenic nematode species as usual; one of the innovative strategies to control plant-parasitic nematodes would be to manage diversity in communities in order to lead them to be less pathogenic. The plants and their materials are one of the potential remedies for nematodes management. Turmeric (Curcuma longa) along with its several biological applications may serve as a biopesticide against Meloidogyne incognita, a nematode species. A bioassay guided isolation of various fractions of turmeric was subjected to nematicidal activity in comparison with Azadirachta indica against Meloidogyne incognita larvae at the concentration of 0.25, 0.5, and 1% for 48 hours. Alongside, Larvae and eggs of nematodes were inoculated around the tomato seedlings in experiments with turmeric in a growth chamber. The control contains water instead of turmeric. Root gall severity and final nematode population were suppressed significantly. It was observed that the use of turmeric is very important for selected plant parasitic nematodes management.

Plant-parasitic nematodes represent a substantial constraint on global food security by reducing the yield potential of all major crops. The soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) is widely distributed across important soybean production areas of the U.S., being the major soybean yield-limiting factor, especially in the Midwestern U.S. Double cropped (DC) soybean is commonly planted following winter wheat. We previously reported double-cropping soybean fields with reduced SCN counts compared to fallow at both R1 growth stage (beginning of flowering) (−31.8%) and after soybean harvest (−32.7%). To test if higher counts of beneficial and SCN antagonistic microorganisms could be correlated with the suppression of SCN in fields previously planted with wheat, three field locations with noted SCN suppression were selected for a metagenomics study. Ten subplots were selected (5 wheat and 5 fallow pre-soybean) from each location. A total of 90 soil samples were selected: 3 fields ×2 treatments × 3 timepoints × 5 replications. Three DNA markers targeted distinct microbial groups: bacteria (16S V4-V5), fungi (ITS2), and Fusarium (tef1). Amplicons were sequenced using an Illumina MiSeq platform (300 bp paired-end). Sequencing datasets were processed in R using the DADA2 pipeline. Fungal populations were affected by location in all sampling periods and differed significantly between DC and fallow plots at soybean planting and after harvest (P < 0.001). Several enriched fungal and bacterial taxa in wheat plots, including Mortierella, Exophiala, Conocybe, Rhizobacter spp., and others, were previously reported to parasitize SCN and other plant-parasitic nematodes, suggesting a potential role of beneficial microbes in suppression of SCN in soybean fields double-cropped with wheat.
