Sign In Question: In general, Meloidogyne incognita completes its life cycle within…
✅Explanation:
Meloidogyne incognita, commonly known as the southern root-knot nematode, has a relatively short life cycle. Under favorable environmental conditions (e.g., warm temperatures and adequate moisture), it can complete its life cycle from egg to egg-laying adult in about 25-30 days.
Egg: Eggs are laid in a gelatinous matrix by the female nematode.
Juvenile (J1, J2): The first two juvenile stages occur within the egg. The second-stage juvenile (J2) is the infective stage and hatches from the egg.
Juvenile (J3, J4): The J2 penetrates the plant root and molts into the J3 and J4 stages within the root.
Adult: The final molt leads to the adult stage. Females become sedentary and swollen, while males remain vermiform (worm-like) and can leave the root.
Egg Production: Females produce eggs, completing the life cycle.
