Fig. 2. 3 H-palmitic acid incorporation by the posterior midgut in the days following feeding. Adult females were fed with non-radioactive blood. On different days after feeding, the posterior midguts of adult females were dissected and 3 H-palmitic acid was added at the luminal side and incubated in the culture medium. One hour later, the midgut was dissected and homogenised and the radioactivity of the extracted lipids was determined by scintillation counting. The vertical bars represent the standard error for three determinations. Asterisk means the statistical analyses p < 0.01. cpm: counts per minute.
