LIFE CYCLE

The life cycle completed in 25 days at 27 °C, but it takes longer time at lower or higher temperatures. When the egg hatch, the infected second stage juveniles may migrate from within galls to adjacent parts of the root and cause new infections in the same root, or they may emerge from root and infects other roots of the same plants or roots of the other plants. The greatest numbers of root-knot nematode are usually in the root zone from 5-25 cm below the surface. The schematic diagram of the root-knot nematode life cycle shows the clear life span of the nematode.
