“…However, Latin American countries are faced with a considerable challenge because the genus Pomacea is endemic to the region and several species that are superficially similar to P. canaliculata are freely cultivated or traded (e.g. “tote” – Pomacea flagellata (Say) in Mexico, Iriarte‐Rodríguez & Mendoza‐Carranza, ; “churo” – P. maculata in Peru, Alcántara Bocanegra et al ., ). Furthermore, both Colombia and Peru include parts of the natural distribution range of P. maculata (Hayes et al ., , ), but are separated from rice‐growing centres by the Andes Mountains.…”

This review relates the ecology and physiology of apple snails (Ampullariidae) to their impact on rice-production systems. Two species in particular, Pomacea canaliculata and Pomacea maculata, have been introduced to several rice-growing regions. Flooded rice systems represent a high-quality habitat for these apple snails because of similarities in the environmental conditions (water temperature, salinity, pH, water flow velocity) necessary for both rice production and for snail survival and development. Furthermore, amphibious respiration, a capacity to aestivate during dry periods, as well as cold acclimation and tolerance (particularly in P. canaliculata), increases the resilience of apple snails to rice farming practices, including agrochemical applications, intermittent drainage and crop rotations -under a wide range of climatic conditions. Risks to regional rice production depend on four principal factors: these are (a) regional climate, (b) regional rice-production systems, (c) prevailing production practices, and (4) the presence/absence of invasive, non-native apple snails. Based on these criteria, lowland irrigated rice in tropical and subtropical regions that is wet-direct seeded is most vulnerable to damage from both native and non-native apple snails (albeit with greater losses from non-native snails because of normally higher densities). Adequate quarantine regulations, particularly in vulnerable tropical regions that are adjacent to centres of recent outbreaks (e.g. India and Bangladesh adjacent to Myanmar, Peru and Colombia adjacent to Ecuador) and attention to the preparedness of farming systems could reduce potential impacts as these highly invasive snails continue to spread. The urgent development of labour-saving crop-establishment methods that reduce dependencies on chemical molluscicides is necessary to achieve sustainable rice production in regions at risk from non-native apple snails.

This study investigated the behaviour of Pomacea bridgesii, describing the daily activity, substrate selection and the influence of the flood regime in the Amazon, the species’ native habitat. The present study described the daily activity and substrate selection, and evaluated the activity adaptations of the gastropods in a simulated flood-pulse regime. Gastropods were collected in Amazonas, Brazil, in June 2013. Assessments of the daily behaviour, substrate selection, and flood-pulse simulation were made in experimental water tanks. The snails were observed hourly for 48h, and their behaviour recorded on an ethogram. The snails were more active during the night, when up to 80% of them moved about. In general, during both day and night, the gastropods used the pebble substrate most often. Comparing the day periods, a significant proportion of the individuals that were using the pebbles moved to other substrates (t=5; d.f.=2; P=0.03). The interaction of the behaviour of P. bridgesii with the simulated flood-pulse regime showed a statistical difference between the dry period and the period of maximum water level. The water regime of the Amazon floodplain directly influenced the activity of P. bridgesii, with responses including self-burying and activity interruption, with the operculum closed to minimise water loss.

This study investigated the predation of eggs of the apple snail Pomacea dolioides in Itacoatiara, Amazonas, Brazil. Predation was compared between rural and urban areas, period of day, shaded and unshaded clutches. In addition, we evaluated clutch height and the behaviour of predators. Between April 2017 and July 2018, 962 egg clutches were observed at different times of the day: 492 in rural areas with predation of 68 egg clutches and 470 in urban areas with predation of only 9 egg clutches. Significant differences were recorded for predation rate and differences were recorded for egg clutch height in the areas. In the rural areas, the most frequent predators during the day were ants Solenopsis invicta, Crematogaster cf. carinata and the most abundant were S. invicta, Wasmannia aff. iheringi and C. cf. carinata. During the night, S. invicta was the most frequent and abundant predator. In urban areas, the frequency of predation and abundance of S. invicta were higher during the day and night than those of other predators. Populations of P. dolioides in rural areas are more affected by egg predation, mostly by S. invicta and C. cf. carinata, and predatory behaviour depended on the species of the predator.
