Field surveys were conducted in three oil palm producing regions of Ghana to determine the frequency, population density and geographical distribution plant parasitic nematodes associated with palm. Palms ranging from 4 12 years surveyed during peak periods two successive cropping seasons 2019 2020. A total 64 soil root samples collected extracted identified them. 716 mixed populations 11 econo...

Although one of the ultimate goals of ecotoxicology is to predict the effects of chemical substances and compounds on whole communities and ecosystems, it is generally accepted by ecotoxicologists that single-species toxicity tests may provide an adequate first step toward the ecological risk assessment of pollutants in soil and water. Consequently, several toxicity tests (ASTM 1993) have been ...

We investigated the effects of three botanicals with nematicidal properties (anise-Pimpinella anisum, parsley-Petroselinum crispum, and rocket-Eruca sativa) on soil nematode community, in terms trophic structure genera composition. compared those fluopyram (synthetic nematicide) Nemagold (bionematicide). assessed role time, by sampling 15 45 days after treatments analyzing microbial phospholipi...

Background: Parasitic nematodes are very destructive to crops, ornamental plants and woody as well which cause most severe diseases in feed on the roots of these plants.
 Objective: Main aim this study is identify different species associated with Maple (Acer caesium) Poplar (populous nigra) trees at district Swabi, Khyber Pakhtunkhwa, Pakistan.
 Methodology: Some growing areas Distri...

in order to identify the plant parasitic nematodes of pulse fields in northern khorasan province, 41 soil and root samples were collected from rhizosphere of pisum sp., phaseoulus sp., lens sp. during 2011 and 2012. the nematodes were extracted by combined sieving and centrifugal-flotation method of jenkins (1969) and transferred to glycerin by using method of de grisse (1969). the permanent sl...

LEA (late embryogenesis abundant) proteins in both plants and animals are associated with tolerance to water stress resulting from desiccation and cold shock. However, although various functions of LEA proteins have been proposed, their precise role has not been defined. Recent bioinformatics studies suggest that LEA proteins might behave as molecular chaperones, and the current study was under...

Aβ (amyloid β-peptide) has a central role in AD (Alzheimer's disease) where neuronal toxicity is linked to its extracellular and intracellular accumulation as oligomeric species. Searching for molecules that attenuate Aβ aggregation could uncover novel therapies for AD, but most studies in mammalian cells have inferred aggregation indirectly by assessing levels of secreted Aβ peptide. In the pr...

The anterior sensory anatomy (not including amphids) of the nematode Aphelenchus avenae (Tylenchomorpha) has been three-dimensionally reconstructed from serial, transmission electron microscopy thin sections. Models, showing detailed morphology and spatial relationships of cuticular sensilla and internal sensory receptors, are the first computerized reconstruction of sensory structures of a Tyl...
