Lipoproteins of the egg perivitelline fluid ofPomacea canaliculata snails (Mollusca: Gastropoda)
The Journal of Experimental Zoology, 1996The lipid and protein composition of the perivitelline fluid of the eggs of Pomacea canaliculata was investigated. Two lipoproteins (PV 1 and PV 2) and one lipoprotein fraction (PV 3) were detected for the first time in gastropods. They represent 57.0, 7.5, and 35.5% of the egg total proteins, respectively. PV 1 is a glyco-carotene-protein complex with

Spontaneous and induced egg laying behavior of the pond snail,Lymnaea stagnalis
Journal of Comparative Physiology A, 1989InLymnaea egg laying is initiated by the discharge of the neurosecretory caudodorsal cells (CDCs), which release an ovulatory hormone (caudodorsal cell hormone; CDCH) and other peptides. Egg laying is a complex behavioral pattern composed of various postures and action patterns. This paper describes the egg laying behavior of intact and freely behaving

Effects of 2,2′-dichlorobiphenyl on egg laying in the pond snail Lymnaea stagnalis
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1992Abstract 1. Effects of 2,2'-DCB on reproduction of the pond snail Lymnaea stagnalis have been studied with special emphasis on the neuroendocrine caudo-dorsal cells (CDCs). 2. Treated snails showed increased latencies of egg-laying after the clean-water stimulus needed for induction of egg-laying but not after injections with CDC-hormone containing ...

[Study on the effect of bromoacetamide upon the development of snail eggs].
Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 1993This paper deals with the influence of bromoacetamide on the development of snail eggs, its effect on inducing diapause of snail eggs at different developmental stages (blastula, gastrula, trochophore and veliger) both at different concentrations of bromoacetamide at the same time and at same concentration at different times.

Inhibition of Egg Hatching of the Golden Apple Snail by Synthetic Molluscicides
2016Golden apple snail is an invasive freshwater snail species that originates from South America. This snail is considered a threat to paddy rice which has caused great attention all over the world. In Malaysia, synthetic molluscicides have been used to control the golden apple snail without much success. Hence, it is imperative to find a practical method

The biochemical defenses of Pomacea snail eggs are effective against mealworm beetles
Journal of Experimental BiologyABSTRACT Eggs of freshwater snails from the genus Pomacea (Caenogastropoda: Ampullariidae) are rarely predated because of their strong anti-predatory defenses present in the perivitelline fluid (PVF) that surrounds the embryos. There are clade-specific defenses: the Bridgesii clade expresses enterotoxic lectins, whereas the more ...

Degeneration of CDCs and egg laying in the pond snail Lymnaea stagnalis.
Acta biologica Hungarica, 1997In the pond snail Lymnaea stagnalis egg laying is induced by multiple peptides, which are released by the neuroendocrine caudo-dorsal cells (CDCs). Egg laying in Lymnaea starts at about 50 days and increases initially with age to decreases again at an age of about 250 days.
