Pineapple (Ananas comosus L. Merr) is one of Indonesia’s important fruit commodities. Indonesia became the world’s fourth-largest pineapple producer in 2020. The monoculture cultivation system can lead to the continuous presence of pests and diseases in plantation areas. Mealybug wilt disease is caused by Pineapple mealybug wilt-associated virus (PMWaV) and its thought to be associated with phytomatodes. This study aims to determine the type of phytomatodes in pineapple plants with three health degrees: healthy plants, moderate symptoms, and severe symptoms. The soil and roots were sampled at 3, 5, 13, and 14 MAP (Month after Planting). Nematodes were extracted from the soil using the flotation-centrifugation method, while the root samples were extracted using the mist chamber method. Identification of nematode morphology was based on anterior (mouth and stylet shape), posterior (tail shape and reproductive organs), and the type of annulation or nematode cuticle surface. Seven genera of phytomatodes were identified from soil and root samples: Pratylenchus spp., Rotylenchulus spp., Meloidogyne spp., Helicotylenchus spp., Crinonemoides spp., Tylenchus spp., and Rotylenchus spp.. The dominant phytonematodes in the soil samples were Rotylenchulus spp. (66.67/100 ml of soil), while Pratylenchus spp. predominated in the roots (58.33/10 g of roots). Based on the three degrees of plant health, the phytonematodes that dominated the soil samples were Rotylenchulus spp. on the health degree of healthy and moderate symptoms, and Meloidogyne spp. dominate the sample at severe symptoms. Pratylenchus spp. dominated the root samples at healthy and severe symptoms, while Rotylenchulus spp. predominate in moderate symptomatic samples.

Diversity and population densities of plant-parasitic nematodes in commercial and smallholder pineapple production in Kenya

et al. 2021

Summary Plant-parasitic nematodes (PPN) cause significant yield reduction in commercial pineapple (Ananas comosus) worldwide. In Kenya, few nematode studies have been conducted, although the main commercial pineapple producer has sole dispensation to use Telone II (1,3-Dichloropropene) indicating the magnitude of the nematode problem. This study was conducted with the aim to investigate the population densities and diversity of nematodes in two commercial plantations with two contrasting management practices. We additionally assessed the influence of crop age and compared this with nearby smallholder pineapple production systems. Soil and root samples were collected from fields of different ages in each commercial plantation and from 29 smallholder fields. A total of 18 genera were associated with pineapple, with a relatively greater diversity found in smallholder than commercial farms. The most prevalent genus was Meloidogyne spp. (M. javanica) followed by Helicotylenchus spp., Tylenchus spp. and Aphelenchoides spp. PPN densities were higher in relatively older fields of 24 and 36 months than from fallow and 3-month-old fields. Regression analysis additionally demonstrated the rise of PPN densities with age of pineapple fields, especially Meloidogyne spp., while free-living nematode densities declined. This study provides an indication of the high level of PPN infection in pineapple in Kenya, which would constitute an important factor contributing to low yields. The study confirms an obvious need for pineapple producers to control PPN to improve crop yields.
