Abstract: In order to systematic study the response of different sizes of Pomacea canaliculata to dry and wet environment in agricultural control, both overwintering experiment and paddy-upland rotation experiment were conducted. The results showed that the survival rate of small, middle and large Pomacea canaliculata were 91.33%, 83.00% and 72.67% without water, respectively. They were higher than that within water, which were 60.00%, 46.00% and 38.67%, respectively. The mortality of large Pomacea canaliculata were highest no matter within or without water. In paddy-upland experiment, the control effects of previous crop on small-middle ones were 63.4% (soybean),68.4% (maize) and 57.4% (pepper), respectively, which were higher than those of adults.

Key words: Pomacea canaliculata, overwintering, paddy-upland rotation, agricultural control
