• The resumption of motility of the motionless 4th-stage larvae of Paratylenchus aciculus, collected after storing in host-free soil for 60 days, was induced by immersion for about 7 hr in either distilled water or root exudate of host plants. However, the root exudate induced the 4th-stage larvae to become lethargic prior to the final molt more rapidly than did distilled water so that there was a higher rate of adult emergence in root exudate than in distilled water. The log activity value of the mulberry root exudate used was 4.04. The time necessary for receipt of the stimulating substance was at least 24 hr. Lethargic larvae in the final molt were no longer able to survive under adverse conditions. The ecological role of the 4th-stage larva in the survival of this species is discussed.
