Figure 10.

The effects of VU573 (10 µM) on transepithelial electrolyte and fluid secretion in isolated Malpighian tubules of the yellow fever mosquito. Isolated Malpighian tubules were bathed in K⁺-rich Ringer solution as in Figs. 2B, 5 and 9A. Rates of fluid secretion were assessed in 5 periods (P) lasting 30 min each. A. Initial stimulation in P2 and P3 and late inhibition of fluid secretion in P5. B. Initial stimulation of KCl and water secretion. C) Late inhibition of KCl and water secretion. Data are from paired sister tubules. Asterisk indicates statistical significance. For more detail see Rouhier et al.⁵⁵
