“…The digestive tract of A. fulica consists of a large pharyngeal muscle, provided with a chitinous radula, esophagus, stomach, intestine and large intestine (rectum) (ZAITSEVA et al, 2009). The stomach is connected by ducts with liver occupying most of the visceral sac (ZAITSEVA et al, 2009), and possess an alveolar liver, which is the main organ of digestion and absorption of food. Activity of hydrolytic enzymes in the digestive juice of Helix spp.…”

“…There is correlation of AChE activity in the pedis plexus of M. abbreviatus with probable presence of cholinergic circuits in pedal ganglia, suggesting that structures of this nerve plexus are also involved in these circuits, promoting mobility (FACCIONI-HENSER, 1999) and ganglia in the brain of the same species, suggesting its involvement in neuropeptide metabolism, with role in the modulation of eating behavior such gastropod (ZANCAN et al, 1997). ZAITSEVA et al (2009) found similarities in the distribution of activity of cholinesterase (AChE) in the digestive tract of Littorina littorea (Linnaeus, 1758) (Neotaenioglossa, Littorinidae) and A. fulica. The nerve fibers of the granule cells of the digestive tract of L. littorea and A. fulica show cholinesterase activity (ChE), forming varicosities or terminations with high activity of this enzyme in these cells KUZNETSOVA, 2008).…”

The giant African snail Achatina fulica was introduced in Brazil and since then has become an important pest, because of its resistance to abiotic conditions, hermaphroditism, polyphagia, and absence of natural predators. This study aims to evaluate the control of A. fulica in lettuce, in Alagoas, Brazil. Bioassays for the determination of lethal dose and lethal time to adults of A. fulica and the egg mortality were performed in the laboratory by applying commercial synthetic products, commercial and non-commercial alcoholic botanical extracts on mollusk adults. Additionally, the protein concentration, lipase activity and enzyme acetylcholinesterase (AChE), and butyrylcholinesterase (BuChE), in the stomach, intestine, nervous ganglion and liver were determined. The alcoholic extract of Capsicum frutescens caused higher mortality of A. fulica, and the alcoholic extract of C. frutescens and Piper tuberculatum oil can prevent the hatching of A. fulica. The lipase activity was present and in greater quantities in tissues, stomach, intestine, liver and ganglia of A. fulica, before and after exposure of the alcoholic extract of C. frutescens. The enzymatic activity of BuChE was present in the ganglia and liver of A. fulica, prior to exposure of the alcoholic extract of C. frutescens. The enzymatic activity of AChE was present only in the ganglion and absent in liver of A. fulica, prior to exposure of the alcoholic extract of C. frutescens. The concentration of 10% of the alcoholic extract of C. frutescens caused 84% mortality of adult A. fulica in lettuce in field conditions.

“…As the apical poles of the majority of these cells contact the digestive cavity, they probably function as receptor cells. The wall of the digestive tract beneath the epithelium was shown to contain neurons forming microganglia and nerve plexuses (Zaitseva et al, 2009). The system of small peripheral ganglia found in the walls of the internal organs in nudibranchs was identified as the sympathetic nervous system (Bullock, Hor-ridge, 1965).…”

“…The system of small peripheral ganglia found in the walls of the internal organs in nudibranchs was identified as the sympathetic nervous system (Bullock, Hor-ridge, 1965). Many of the regulatory cells located in the wall of the gastropod digestive tract can be cholinergic or NO-ergic, as they show acetylcholine transferase activity or NADPHdiaphorase activity, respectively (Zaitseva, Kuznetsova, 2008;Zaitseva, Markosova, 2008;Zaitseva et al, 2009). In several species of gastropods, the intestinal wall contains intraepithelial FMRFamide-im cells (Punin, 2001, Zaitseva et al, 2004.…”

Whole mount preparations of juvenile Cadlina laevis aged 2-4 months after hatching were examined by immunocytochemistry and histochemistry in conjunction with confocal laser microscopy to study the architecture of the digestive system, its musculature and distribution in the digestive system of catecholamine-containing, 5-HT and FMRFamide-immunoreactive (im) nervous elements. The largest number of catecholaminecontaining and FMRFamide-im nervous elements was found in the wall of the pharynx, the stomach and the digestive gland. The 5-HT-im innervation was observed primarily in the pharyngeal region of the digestive system. Catecholamine-containing and FMRFamide-im receptor cells were revealed in the oral velum around the mouth. How to cite this article: Zaitseva O.V., Shumeev A.N. 2017.
