About 50% of the nematode population survived after a 5-month period of drought in the absence of a host.
The percentage of surviving nematodes was greater under a dry soil regime than under a dry-wet regime.
Most of the surviving inactive anhydrobiotic S. rugosus were adults; they resumed activity after 24 h of soil wetting.
Optimum temperature for recovery from anhydrobiosis after soil wetting was 25C. (Hashemi et al., 2020)

Damage:

Patches of weak and yellow wheat seedlings in fields in Iran where wheat was planted after maize. Maize is a susceptible host (Hashemi and Karegar, 2018).
