Fig. 1. Production of predominant cuticular hydrocarbons in 4-day-old males as a function of the temporal induction of heat shock. Values are means of absolute amounts (ng) ± S.E.M. A single 1 h heat-shock pulse was induced between adult eclosion (AE) and 72 h AE. Four genotypes were used: (A) Cs; (B) hsp70-GAL4; Cs (hsp-Cs); (C) hsp70-GAL4 x UAS-lacZ (hsp-lacZ); (D) hsp70-GAL4 x UAS-tra (hsp-tra). For each genotype, data from non-heat-shocked flies (no HS) are shown on the right of each graph. For each data point, N=9-29 (except for hsp-Cs at 24 h; N=4). For abbreviations of hydrocarbons, see legend to Fig. 3.
