Abstract
Pratylenchus thornei, the root-lesion nematode, is widely distributed in wheat (Triticum aestivum) growing areas of many countries and is of particular concern in sub-tropical environments (Thompson 2015). These nematodes penetrate roots to feed and reproduce in the root cortex leading to loss of root function, which affects nutrient and water uptake of nutrients and water causing nutrient deficiency and water stress (Thompson 2015).
In the original paper the population response of P. thornei in Queensland, Australia wheat to temperature is modelled using a linear and quadratic equations. The study aimed to investigate the effects of soil profile temperatures after different sowing dates on reproduction of the nematodes in susceptible and moderately resistant wheat cultivars in the subtropical grain region of eastern Australia. This document recreates the models for population densities of P. thornei as described in the original paper.
