abstract
Pomacea canaliculata and Pomacea maculata attack rice growing areas with significant yield losses. Their success rate is mainly due to their high reproductive potential. This study aimed to investigate the reproductive potential of both Pomacea spp. using a digital infrared CCTV video camera system to ensure data accuracy by recording uninterrupted behavioral activities. Results of the study confirmed efficiency of digital infrared CCTV camera system used in recording and acquiring behavioral data with further potential for wide scale usage in future studies. Moreover, mating and oviposition in both species mostly occurred during night hours. Pomacea maculata showed higher mating frequency, oviposition duration and eggs per clutch, whereas egg diameter was higher in P. canaliculata. No difference was observed in other mating and oviposition parameters. Accordingly, higher reproductive potential of P. maculata as compared P. canaliculata could be one of the reasons for its large scale distribution in Peninsular Malaysia.
