“…In land snails, processes such as gametogenesis and mating behavior may be influenced by temperature, humidity and photoperiod (Leahy, 1984;Azevedo et al, 1996;D'ávila et al, 2004;D'ávila and Bessa, 2005;Junqueira et al, 2008; al., 2009) because these factors can act as regulators of metabolic processes (South, 1992).…”

The objective of this study was to evaluate the variation of energy substrates in different seasons in Bulimulus tenuissimus. For this evaluation, substrates were collected from the digestive and albumen glands and foot tissues, which were processed to obtain the concentrations of glucose and galactose. There was seasonal variation in energy reserves in both the digestive gland and the foot of Bulimulus tenuissimus, with a tendency to accumulation from spring to winter. There was greater use of energetic reserves in the spring and summer, being the glycogen stored in the digestive gland the first source consumed. In addition, mobilization of reserves of glycogen in the muscle in summer was observed. The reduction of glycogen coincides with the reproductive cycle of the species, and the expenses generated for the processes of mating and gametogenesis was the cause of this reduction. The concentration of galactogen also varied according to the reproductive period. It was suggested that variations in temperature and photoperiod that occur during the year would act as regulatory mechanisms of energy metabolism of B. tenuissimus.

Terrestrial molluscs can become agricultural pests and transmit parasites, playing an important role in different biological communities. In the present study, we evaluated the diversity and abundance of this group in two horticultural areas in Rio de Janeiro (Manguinhos and Jacarepaguá neighborhoods), as well the presence of parasitic nematodes associated with these molluscs. We collected specimens in the austral spring and summer, with four sites being sampled within each study area, including malabar spinach, sweet potato, chicory greens, and cassava plantations, and one site in an adjacent, non-cultivated area. We collected a total of 522 live mollusc specimens and identified 16 species from 10 different families. The greatest abundance of molluscs was recorded in summer (363) and at Jacarepaguá (309). Overall, 174 (57%) of the 303 specimens analyzed parasitologically were positive for nematodes. Larvae of superfamily Metastrongyloidea, which includes nematodes that are a concern for public health and veterinary medicine, were found parasitizing the slug Sarasinula linguaeformis, in Manguinhos. Our results contribute to understanding of the diversity of terrestrial molluscs occurring in kitchen gardens in the city of Rio de Janeiro, and provide important insights for generating subsidies for health education actions and control of parasitic diseases transmitted by them.
