Our study aim was to analyse the impact of root infection by root-knot nematode (Meloidogyne incognita) on the performance of aboveground chewing herbivores (beet armyworm Spodoptera exigua). We evaluated several performance indicators including larval weight gain, developmental time, mortality, pupal weight, pupation time and sex-ratio using the pupa. The tomato plants were infested with the root-knot nematode for 5, 15 and 30 days before infesting the leaves with Spodoptera exigua caterpillars. The caterpillars were allowed to feed on the tomato plants until they reached the pupa stage or died. During this time, we measured each of the above-mentioned performance indicators at two day intervals. Our results show that root-knot nematodes enhance the performance of above-ground caterpillars depending on the nematodes' root infection cycle stage.
