✦ Synopsis

Effects of piperonyl butoxide and carbaryl synergism were studied on the metabolism of the snail Lymnaea ctcuminata. Snails were exposed to 40 yo and 80 yo of the 48 h LCs0 of carbaryl or carbaryl tpipeionyl butoxide mixture (1 : 5 ) . The amount of carbaryl present in the LCSo mixture was only 0.23 yo of the LCao of carbaryl alone. The treatments caused a dose-dependent decrease in glycogen and protein levels and acctylcholinesterase ( AChE) and alkaline phosphtLtase activity; simultaneously, there was an incrctise in levels of lactic acid, reducing sugars and amino acid and the activity of acid phosphat.ase. Significant differences in AChE and phosphatnse activity were also observed between the effects of equivalent concentrations of carbaryl and carbaryl-synergist.
