Abstract: A cultura da mandioca (Manihot esculenta) tem importância socioeconômica no Brasil, no entanto há ainda uma escassez de informações sobre a associação de nematoides fitoparasitas, bem como ao comportamento de cultivares de mandioca ao parasitismo desses agentes. O objetivo do presente trabalho foi relatar a distribuição geográfica e novas ocorrências das principais espécies de nematoides encontradas associadas à mandioca em diferentes municípios dos estados do Acre, Amapá, Pará e Rondônia.

“…A modification of Cobb's method was used to extract the nematodes from soil and root (Ravichandra, 2014). Nematodes were killed by heat at 65°C for 4 min and then fixed with 2% formalin (Rosa et al, 2014). Key morphometric measurements for the genus (Table 1) were taken according to Robinson et al (1997), Van den Berg et al (2015), and Palomares-Rius et al (2018).…”

Family farming plays an important role in the Brazil's food supply, contributing about 87% of the national cassava production (Food and Agriculture Organization of the United Nations [FAO], 2016).…”
