The study aimed to assess the effects of mango and sampalok on the reproductive capability of golden apple snails. Three concentrations of the two plant extracts were prepared. Five pairs of male and female snails were exposed to these extracts for three days. The snails were observed for fifteen days after their exposure to the extracts. Possible changes in the subject's feeding behavior, death rate and reproductive capability were noted. The consumption of feeds was monitored daily and the number of incidental deaths per day was recorded. To determine if the extracts, indeed, had an effect on reproductive capability, the emergence of egg clusters, including the number of individual eggs, and the number of hatchlings were also recorded. The plant extract in which the group that gave the least and smallest egg clusters and the lowest number of hatchlings had been exposed to would be declared as the more effective agent of pest control between the two. Data gathered proved that both of the two plant extracts rendered negative effects on the golden apple snail's feeding behavior, mortality and reproductive capability. And sampalok, having rendered the most detrimental effect on the snail's mortality and the most damaging effect on its reproductive capability, was declared to be more effective.
