Ecological Interaction in the Proliferation of Phytoparasitic Nematodes in Coffee var. Typica

Phytoparasitic nematodes are a common problem in coffee production worldwide. In Peru, the proliferation of phytoparasitic Coffea arabica L. var. Typica has negative impacts on and huge economic losses. The objective this study was to determine ecological interactions that influence C. Quillabamba, Cusco, Peru. density soil root evaluated using modified Baermann channel method. Identification genera species carried out different samples, based descriptions taxonomic keys. Physical chemical parameters were evaluated. Principal component analysis (PCA) correlation network employed distribute nematodes. variables texture, organic matter, pH, altitude, temperature humidity used. During sampling, several plant-parasitic identified addition various categories Meloidogyne exigua, Pratylenchus coffeae, Allotrichodorus longispiculis Helicotylenchus longicaudatus among specific identified. genus with highest incidence spp. 77.3% 96% roots, reaching an average 340 100 g 368 1 roots. PCA results show 63.7% variability data is retained first two components. shows sampled areas differentiated grouped characteristics, while overlap representation analysis, thus making it difficult select them. Pearson’s showed between altitude nematode (−0.22), suggesting conditions at higher altitudes may be more unfavorable for growth. addition, positive found pH matter (0.93, p < 0.001) density. factors plant roots multiple complex, their understanding essential success production. finding current useful development sustainable strategies managing
