“…Toda a superfície externa do corpo desses moluscos é provida de células neurossensoriais, que são muito abundantes ao longo das margens do pé e na região anterior do corpo, incluindo os tentáculos e as pregas orais (HYMAN 1967, CHEVALIER et al 2000.

“…Os moluscos terrestres são capazes de reconhecer compostos químicos voláteis e não-voláteis por dois mecanismos distintos: a percepção olfativa e gustativa, respectivamente (STEPHENSON 1979, IGLESIAS & CASTILLEJO 1999, CHEVALIER et al 2000. STEPHENSON (1979) obteve evidências comportamentais do papel dos tentáculos anteriores e posteriores na detecção de compostos químicos voláteis e não-voláteis, assim como da função gustativa da probóscide, lábios e lobos laterais da boca de moluscos da espécie Deroceras reticulatum (Müll.).…”

que favorecem a agregação incluem características do ambiente, tais como diferenças no microclima, heterogeneidade do habitat e distribuição em manchas de recursos; assim como fatores relacionados à reprodução e à sobrevivência dos moluscos, tais como a probabilidade de encontrar um parceiro sexual e o risco de dessecação (KLEEWEIN 1999, COOK 1992 Sub Subulinidae). ulinidae). ulinidae). ulinidae). ulinidae). The current study aimed to verify the existence of aggregative behavior in Subulina octona (Brugüière, 1789) and to obtain behavioral evidence of chemical mediation of this behavior. We used 150 adult animals allocated in 15 boxes with humus (10 animals per box). In each box we placed four identified plastic disks in an equidistant position. These disks worked as shelters for the animals. In experiment I, 10 animals were put in the middle of each box. After 24, 48, 96, 120, 144, and 168 hours we observed the number of formed aggregations, as well as the position of the aggregates (in each shelter), the number of individual per aggregation and the number of isolated individuals. In order to test the hypothesis of conditioning of disks by chemicals compounds, the experiment II was carried out. All the individuals were transferred to other boxes with humus, three new disks and the disk containing the larger aggregate after the 168 hours of the experiment I (denominated conditioned disk). We verified, after 24 and 48 hours, the number of individuals below the conditioned disk. In experiment I, aggregations were observed in every used box and in every time intervals. In all boxes, there was a significant increase in the number of individuals per aggregation and a reduction in the number of isolated individuals until the end of the experiment (ANOVA, p < 0.005). In experiment II, after 24 hours, six from 15 boxes presented aggregations under the conditioned disk, and after 48 hours, seven boxes presented aggregations under conditioned disk. These were the aggregations with a larger quantity of individuals, which suggests the conditioning of the used disks by some factor, possibly a chemical compound. KEY WORDS.

“…Secondary plant metabolites such as glycosides, terpenoids, flavonoids, alkaloids, saponins, phenols and others may prevent or inhibit feeding of herbivorous gastropods (kloos & MccullouGh 1982, webbe & laMbert 1983, Mølgaard 1986, stahl 1988, desbuquois & daguzan 1995, hanley et al 1995, clark et al 1997.

In recent years field bean crops (Vicia faba) have been frequently attacked by slugs. As there are no molluscicides registered for protection of field beans against slugs, alternative anti-slug measures are needed. One of them may be using specific cultivar properties of the plant. The aim of the study was to assess the susceptibility of different field bean cultivars to damage by slugs and to identify the effect of tannin content in plants on the extent of damage. The experiments were performed in the laboratory and in experimental plot conditions on seeds and plants at stages of 3-4 and 5-6 true leaves, which were exposed to Arion vulgaris (Moquin-Tandon) and A. rufus (Linnaeus). The extent of damage was analysed in four cultivars with low seed tannin content and five with high seed tannin content. The extent of damage to the seeds and plants varied depending on the cultivar and the slug species. The plants of the high-tannin Optimal cultivar were less susceptible to damage.

Do terrestrial gastropods use olfactory cues to locate and select food actively?

Having been investigated for over 40 years, some aspects of the biology of terrestrial gastropod's olfactory system have been challenging and highly contentious, while others still remain unresolved. For example, a number of terrestrial gastropod species can track the odor of food, while others have no strong preferences toward food odor; rather they find it by random encounter. Here, while assessing the most recent findings and comparing them with earlier studies, the aspects of the food selection based on olfactory cues are examined critically to highlight the speculations and controversies that have arisen. We analyzed and compared the potential role of airborne odors in the feeding behavior of several terrestrial gastropod species. The available results indicate that in the foraging of most of the terrestrial gastropod species odor cues contribute substantially to food finding and selection. The results also suggest, however, that what they will actually consume largely depends on where they live and the species of gastropod that they are. Due to the voluminous literature relevant to this object, this review is not intended to be exhaustive. Instead, I selected what I consider to be the most important or critical in studies regarding the role of the olfaction in feeding of terrestrial gastropods.
