“…Similar feeding behavior was found in Lauro de Freitas, in that A. fulica fed on species such as Hibiscus spp., Hemigraphis colorata (Blume), Cymbopogon citratus, Carica papaya, Mentha spp. The location of food by A. fulica is powered by its sense of smell, being mainly attracted to garden crops (Farkas and Shorey, 1976;Gallois and Daguzan, 1989) and Urtica dióica L., a species typically used as refuge needs (Grimes and Blyte, 1969). We also found A. fulica feeding on bull feces.…”

The goal of this study was to document the distribution and establishment A. fulica such as their feeding preference and behavior in situ. The study was carried out at the city of Lauro de Freitas, Bahia state, Brazil, between November 2001 and November 2002. We used catch per unit effort methods to determine abundance, distribution, habitat choice and food preferences. The abundance and distribution of A. fulica was most representative in urban area, mainly near to the coastline. Lots and house gardens were the most preferred sites during active hours. The results indicated that A. fulica started their activity at the end of the evening and stopped in mid-morning.

“…Chemoreception in snails is well developed (Rogers, 1971;Farkas & Shorey, 1976;Croll, 1983) but the respective roles of olfaction, taste and post-ingestive effects in feeding choice are not very clear, especially under natural conditions. At the end of our experiment, the C/A ratio of the sweet chemotype differed significantly from the bitter one, i.e.…”

Adult Helix aspersa snails were maintained individually for one week in plastic cages with 9 living Lupinus albus plants as their only food. Among these 9 plants, 3 chemotypes bitter, intermediate and sweet which differed in their alkaloid content were equally represented.Each day, the leaf surface grazed and the number of leaves attacked by the snails were recorded for each chemotype and each snail. A consumption/ attack (C/A) ratio was calculated by dividing the surface grazed (C) by the number of attacks (A). The number of attacks and the grazed area were positively correlated for each chemotype during the whole experiment, and the snails ate similar quantities of lupin each day. After 4 and 6 days of experiment, we noticed a rejection of the bitter chemotype in favor of the intermediate and sweet ones respectively. After the 6th day, the surface grazed per attack was significantly higher on the sweet chemotype than on the bitter plants. We hypothesize that rejection of the bitter chemotype might be related to (i) an alkaloids reaction threshold associated with an increase in the amount of alkaloids in the wounded plants and/or (ii) aversive ingestive conditioning.

“…The odour tracking abilities of gastropods also enable them to be agricultural pests; snails like the European garden snail Cantareus aspersus can find plant food through chemoreception (Farkas and Shorey 1976). The movements of the tentacles while tracking plant odours were characterised in Cantareus aspersus, showing the average angle between the tentacles was 115° (n = 5) (calculated from Lemaire and Chase 1998).…”

“…This is important because many gastropods are narrow-range taxa and may live in threatened habitats (Ponder and Colgan 2002). No previous studies on odour tracking with gastropods have dealt with endemic Australian fauna, but studies have been carried out on the European garden snail Cantareus aspersus (Müller, 1774) (Farkas and Shorey 1976;Lemaire and Chase 1998), which occurs natively in Europe and is present also in parts of the USA and Australia. In addition, the natural history of the Australian rainforest snails of New South Wales is not well understood (Kay et al 1998;Lemaire and Chase 1998;Puslednik 2002).…”

Some gastropods are able to find food sources by following airborne chemical plumes using both tropotaxis and anemotaxis. This study examined odour tracking to food odours with a species of terrestrial gastropod, Meridolum gulosum (Gould, 1864), a native to rainforests in coastal south-eastern New South Wales, Australia. It was demonstrated that M. gulosum moves towards food odours (fungus) in still air, and holds its tentacles at characteristic angles when moving towards an odour source. This snail can detect odours at least 12 cm away from the source in air.
