Damage:

Meloidogyne moensi  causes inconspicuous galls or slight swellings on coffee roots.  (Fig. 2n). Nutrient absorption is compromised by the infected root system, leading to stunting and chlorosis of the host plant. Coffee roots infected by have relatively small galls (1 – 2 mm diam.), each gall containing several females with egg masses retained  inside the gall (Le et al., 2019).
