...Michael P. Kinney; Nicholas D. Panting; Thomas M. Clark The effects of the serotonin-selective reuptake inhibitor paroxetine (2×10 −5 mol l −1 ) on behavior of the larval mosquito Aedes aegypti are described. Four discrete behavioral states dominate larval behavior: wriggling, two distinct types...

... processes linked to V-ATPase activation, but how this is accomplished is still unclear. Here we report that membrane-permeant derivatives of cAMP increase the bafilomycin-sensitive ATPase activity in Malpighian tubules of Aedes aegypti twofold and activate ATP-dependent transport processes. In parallel...
