The ever-present nature and bioactivities of nematodes makes them ecologically important in agro-ecosystem. Preferential by the innate characteristics gifted to all living creatures by nature; they also have the ability to carry out all physical and physiological processes such as reproduction, feeding, excretion, response to stimuli as well as movement from place to place. Spatial and temporal distribution of nematodes in aquatic and terrestrial ecosystem has been well studied (Wu et al., 2008; Lawal and Atungwu, 2013 and Nzeako et al., 2014).
However, an intensely managed arable land have been alleged by (Ferris and Ferris, 1974 and Lawal and Atungwu, 2013) to sustain profusion of plant parasitic nematodes than do non–arable lands. As major player in the soil food chain (Wu et al., 2008), nematodes have been reported to contribute immensely to the rate of decomposition of plant litter and turnover of nutrients from soil organic matter (Wu et al., 2008 and Lawal and Atungwu, 2013) and many researchers have investigated into nematode communities in natural ecosystems and agro ecosystems including differences linked with land management practices (Liang et al., 2002 and Okada and Harada, 2007). Besides being a source of substrate on which other soil mesofuana feed (Atungwu et al., 2012), nematode population in agro-ecosystem can respond in a predictable way to ecosystem disturbance during land preparation and cultural practices involving incorporation of organic materials into the soil (Freckman and Ethema, 1993; Atungwu and Lawal, 2009 and Lawal and Atungwu, 2013). It is therefore necessary to scrutinize the impact of these organic products on the various species of nematodes inhabiting agro-ecosystem to which it is incorporated. This could harmonize the worldwide efforts on the campaign of environmental security with respect to soil protection and climate as nematode community on agricultural soils can be used as indicators of climate change (Bongers, 1990 and Lawal and Atungwu, 2013) This study intends to evaluate the species of nematodes that could be found in eggplant fields where organic agriculture is practiced.
