Root-knot nematode completes its life cycle in:

✅Explanation:
Environmental factors like temperature and soil conditions influence the duration of the life cycle. However, 28-30 days is the standard range under ideal conditions.

🛑 Additional Information::
The life cycle of the RKNs is completed in 25–28 days at 27 °C temperature and divided into different stages (viz., eggs, juveniles, and adults) but this period is changed due to soil moisture (lesser extent), soil temperature (widely) and availability of a suitable host.
The successful completion of the life cycle, involving sequential molts from egg to adult, includes morphologically and functionally distinct stages. In optimal conditions, a single female can produce 200–500 eggs in a mucilaginous matrix.
