Life cycle of SCN. A, Cysts. B, pi-J2s (gray) hatch and migrate toward the root of soybean. CS and CR, i-J2 nematodes burrow into the root and migrate toward the pericycle (green). DS and DR, i-J2s select a cell (yellow) for feeding site establishment. ES, i-J2 nematodes have molted into J3. ER, i-J2 nematodes do not increase in size. FS, The J3s undergo a subsequent molt into J4 nematodes. Meanwhile, the female continues to grow circumferentially as it feeds. The male discontinues feeding at the end of its J3 stage. Male and female J4 nematodes become adults. The vermiform male (blue) burrows outside the root and subsequently copulates with the female. FR, The syncytium collapses and the nematodes do not grow. GS, After approximately 30 d, the female with eggs is clearly visible and emerging from the root. Figure adapted from Klink et al. (2009a).
