“…Thus, it can be predicted that the inhibitory effect of M. rosenbergii will be limited for populations of larger-sized adults. This result is partly attributable to the small size of M. rosenbergii used in the experiment and partly because the shells of subadult or adult P. canaliculata are relatively hard, making it difficult for many predators to break them [21,44,45]. Therefore, when using cultured M. rosenbergii for controlling P. canaliculata invasion, additional measures like manual removal of adult snails may be needed to improve the control effect.…”

“…Biological control, which utilizes inter-species interactions, offers advantages such as durability, high efficiency, environmental friendliness, and relatively low costs [20], making this an innovative approach for Pomacea management [21,22]. One such method is to control the abundance of vegetation that species of Pomacea prefer, which has been proven effective [23].…”

“…Nevertheless, the life cycle of P. canaliculate consists of three stages: eggs, juveniles, and adults, with a total lifespan of 2-5 years [27]; with high egg-production rates, one female snail can reproduce up to 300,000 juveniles annually, and the juveniles can reach sexual maturity within 3-4 months, leading to overlapping generations [28]. Most existing biological control research on these snails has focused on the clearance and control of adults while neglecting their extremely strong reproductive ability, which results in rapid population recovery [21,22,24,25,29]. Therefore, the entire life cycle of P. canaliculate juveniles needs to be considered part of the control effort, but there are few reports on the biological control of juvenile snails.…”

The invasive golden apple snail Pomacea canaliculata has a strong reproductive capacity and has rapidly spread in Asian countries. Current control methods include physical, chemical, and biological approaches, but there has been limited research on the control of P. canaliculata in its different life stages. This study assessed the effectiveness of using giant river prawns Macrobrachium rosenbergii in controlling juveniles of P. canaliculata through a controlled indoor experiment. The density, size, and dispersal range of recently hatched juvenile snails were significantly lower among those kept with prawns than those kept without prawns, indicating a control effect of M. rosenbergii at least on P. canaliculata juveniles. Furthermore, the study speculates on the potential application of M. rosenbergii in the context of a rice–prawn symbiotic system of ecological farming to control invasive P. canaliculata. In terms of effectiveness and safety, its application might lead to a win-win situation for both rice-farm profits and the ecological benefits of invasive species control.

“…This management approach has a detrimental influence on farmers' health and the environment, in addition to the high expenses of purchasing chemical molluscicides. Other green approaches such as using duck and fish as bio-control agents in controlling the population of GAS as one of their food sources have been reported (Abdullah & Reyhan 2017;Azmi et al 2022;Teo & Hamsein 2017). However, this practice is less effective and impractical.…”

Golden Apple Snails (GAS, Pomacea canaliculata) is known in Malaysia as one of the world's worst invasive pest species, wreaking havoc on paddy fields by lowering rice yield dramatically. Farmers now employ chemical molluscicides to eliminate GAS, but these are expensive and have serious health and environmental consequences. Biological control agent using entomopathogenic fungus is preferred over chemical molluscicides to control GAS because it is non-toxic, environmentally friendly and cost-effective. This study is aimed to investigate the molluscicidal activity of an entomopathogenic fungus, Metarhizium anisopliae towards GAS adults and eggs. M. anisopliae conidia were subsequently produced into four concentrations (3×10 4 , 3×10 5 , 3×10 6 , and 3×10 7 conidia/mL) and tested against adults and eggs GAS. The median lethal time (LT 50 ) for the concentration of 3×10 7 took 5 and 3 days to kill 50% of GAS adults and inhibited 50% of eggs from hatching, respectively. Physiological analysis was also conducted on both GAS adults and eggs. The skin of infected individuals became white and opaque, while internal organs such as the pulmonary sac, digestive tract, and hepatopancreas were visibly destroyed. The colour of GAS eggs turned pale after M. anisopliae infestation and resulted in non-viable eggs. This research shows that M. anisopliae is an effective biological control agent for GAS and has the potential to be used as a targeted bio-molluscicide for GAS management.

“…In order to achieve sustainable management of apple snails, biocontrol has been regarded as a substitute for synthetic molluscicides (Azmi et al, 2022). As one of the most severe invasive animals expanding rapidly, a substantial amount of research knowledge and data have been accumulated worldwide.…”

Invasive species pose a threat to global ecosystems and biodiversity, with the apple snail standing out as one kind of the worst invasive species due to its exclusive expansion. In order to draw a conceptual framework of its invasion pattern from an overview, we endeavor to conduct a bibliometric analysis and systematic review to explore the existing knowledge on research history and subjective categorization ofPomacea canaliculataandP. maculata, and to uncover emerging trends of distribution and possible neglected impact on food webs. The research history reveals that the first international research publication was documented in 1958. However, a substantial increase in international publications occurred only after 2000. The adoption and effective implementation of a universally agreed upon management strategy may greatly enhance the progress of research on apple snail invasion. Notably, co-word analysis revealed that the content of each thematic cluster has a shift from basic biology to the monitoring of occurrences and environmental adaptation. Currently, the global distribution of apple snails has expanded to 39 countries primarily as a result of anthropogenic translocation. All infested countries, with the exception of Israel and Singapore, are major paddy rice producers. The northernmost distribution limit is Tyumen in Russia, while the southernmost limit is the Buenos Aires Province in Argentina. Biological control has emerged as a prominent technology for the prevention of apple snail infestations, leading to the identification of 98 non-target enemy species as potential control agents. A taxonomic diversity analysis revealed that these species encompassed a wide range of phylogenetic classifications, including 6 Phyla, 12 Classes, 33 Orders, 55 Families, and 82 Genera. This observation suggests that there is a substantial pool of animals from diverse phylogenetic levels that can prey upon apple snails. Given the high population density and extensive distribution of apple snails, there is a pressing need for further research to explore their potential ecological ramifications. The current understanding of the upward ecological impacts of apple snails remains inadequate. These findings provide valuable insights for future research endeavors and contribute to the effective management of invasive apple snail populations.
