AbstractEnvironmental concerns over conventional nematicides have led to increasing interest in the use of biological control agents to control plant-parasitic nematodes. The development of nematophagous fungi as biological control agents has revealed a need for further understanding of their infection processes. The egg-parasitic fungi, Pochonia chlamydosporia and Paecilomyces lilacinus, and the nematode trapping fungus, Arthrobotrys oligospora, have received the most attention. Through the application of biochemistry and molecular biology, aspects of their infection processes have been elucidated. This has involved the characterisation of enzymes that aid penetration of the eggshell or the nematode body wall and the identification of nematicidal toxins. This growing understanding of the biology of infection is opening new avenues in the improvement of fungi as biological control agents.

Three different plant extracts (Khaya ivorensis, Azadirachta indica and Daniella oleifera) and two Trichoderma species (T. harzianum and T. atroviride), singly and in combination, were assessed on nematode population changes and also in the control of plant parasitic nematodes on tomato under field condition during 2018 and 2019 planting seasons. During each trial, plant parasitic nematodes encountered in the field were Meloidogyne, Pratylenchus, Xiphinema and Helicotylenchus species. The experiment was a randomized complete block design with 4 x 3 factorial scheme and five replications. Factor A being plant extracts (Khaya ivorensis, Azadirachta indica, Daniella oleifera) and control, and factor B being bio-control agents (Trichoderma harzianum, T. atroviride) and control, resulting in 12 treatments. Significant reductions were observed on the population of the plant parasitic nematodes at all treatment levels with neem plant extract, in combination with either T. harzianum or T. atroviride resulted in the greatest significant decrease. Applications of different plant extracts and Trichoderma species, singly and in combination, enhanced the growth and yield of tomato infected with parasitic nematodes.

Plant Parasitic

Several structures associated with feeding by plant-parasitic nematodes have been described using two terms, feeding tubes and feeding plugs. However, both of these terms encompass multiple structures of independent evolution, some of which are functionally distinct. We have reviewed the literature on both structures and provide a new perspective on the function of intracellular feeding tubes to maintain the integrity and efficacy of the feeding site. We propose that they provide sufficient hydraulic resistance against the feeding site pressure to prevent it from collapsing during feeding. In addition, we propose that extracellular feeding tubes of migratory ectoparasites should be considered as the functional analogue of the stylet of all other plant-parasitic nematodes for withdrawal of host cell cytoplasm and, therefore, provide an example of convergent evolution. We also suggest that the main role of the feeding plug, irrespective of origin or composition, may be in adhesion.

Conventional tillage system practices for a long time can reduce soil qualities because of soil erosion, soil compaction and depleting of soil organic matter. Conservation tillage such as No-tillage system can be applied as an alternative technique to rehabilitate soil degradation problems.. This research is a part of a long term study of soil rehabilitation that was conducted from 2010 till now, in PT GMP, Central Lampung. Sampling of nematodes was done on April 2013 when the second ratoon RGM 00-838 variety of sugarcane was 9 months old. The aim of this research was to study the effect of tillage and mulching systems on the abundance of several dominant plant parasitic nematodes. Split plot experimental design was applied on this research. Tillage system as the main plots consisted of intensive tillage and no-tillage systems, while mulching system as the sub-plots consisted of no-mulch and mulching with 80 ton ha-1 of fresh bagasee. Nematodes were collected from 0-20 cm deep of soil and extracted by sieving and centrifugation with sugar solution methods at the Plant Pest and Disease Laboratory, University of Lampung. The results of this research showed that there were eleven plant parasitic and seven free-living nematode genera inhabited the PT GMP sugarcane plantation. The three plant parasitic nematode genera dominant were Hoplolaimus, Xiphinema, and Hemicriconemoides. No-tillage system effectively reduce the abundance of Xiphinema and , mulching with bagasse reduced the abundance of Hemicriconemoides. Meanwhile, mulching on No-tillage system more effective to reducing the abundance of Hoplolaimus compared to intensive tillage system. This results suggested that the No-tillage with bagasse mulching system was one of alternative techniques to control plant parasitic nematodes pest of sugarcane plantation. Keywords : Tillage, mulching, sugarcane, plant parasitic nematodes, abundance.
