The gold apple snail (GAS) Pomacea canaliculata is a freshwater mollusk that has a fast rapid reproduction, and growth; due to these characteristics, the species has become a serious threat to rice producing countries. However, although a wide variety of agrochemicals are used for its control in rice agroecosystems, this species has found suitable environmental conditions for development. Here, two populations of P. canaliculata (one in a rice field, RF and the other in a reference site, RS) exposed to the insecticide MAGIC® (IMC), based on the pyrethroid bifenthrin (3%) and the neonicotinoid imidacloprid (10%), used for the control of bugs. Acetylcholinesterase (AChE), carboxylesterase (CbE) and glutathione-S-transferase (GST) activities were measured in the intestine and hepatopancreas of treated snails at 7 and 30 days after IMC application. In addition, shell morphology of treated snails was measured. The results indicated an inhibition at seven days of CbE and GST activities in the intestine of IMC treated snails respect to controls (p
