Individually plated L4 animals were shifted to the indicated temperature for 24 h at which time the adult was removed. Twenty-four to 36 h later the plates were scored for embryonic lethality. stDf4 is a small deficiency that has been shown to remove act-2 and -3, but not act-1(Wormbase). na, not available.
