Which type of nematode can survive extended periods without hatching?

The soybean cyst nematode is known for its ability to survive extended periods without hatching, which primarily occurs in the form of resistant cysts. These cysts can remain dormant in the soil for several years, allowing the nematode to withstand unfavorable environmental conditions. This resilience enables the soybean cyst nematode to wait for more favorable conditions for hatching and subsequent infestation, which may include the presence of host plants such as soybeans.

Root-knot nematodes, corn needle nematodes, and Lepto nematodes do not possess the same dormant survival strategy as the soybean cyst nematode. While they have their own life cycles and methods of coping with environmental stress, none have the significant capacity for prolonged dormancy in the form of cysts that characterize the soybean cyst nematode. Understanding this unique survival strategy is crucial for effective pest management in field crops, particularly in soybean production.
