Solution(By Examveda Team)
Presence of coarse annules is the distinct feature of Criconematidae family.The family Criconematidae is a remarkable group of nematodes, containing roughly 600 nominal root-ectoparasitic species, of which many species are known to be significant agricultural pests.
Females of Criconemoides myunsugae are characterized by having a ventrally curved body, retrorse annuli with lateral fields marked by discontinuous breaks and anastomoses of transverse striae.
Nematode population can be clearly distinguished from Criconemoides morgensis by first annulus (disc-like vs not disc-like), spermatheca, smaller body length, smaller stylet length, and other measurements.
