Larval development of ovineNeostrongylus linearisin four experimentally infected mollusc species

“…Cabaret (1981) infected Helix (C.) aspersa experimentally with larvae of Muellerius capillaris (Mueller, 1889) Cameron, 1927 and N. linearis and concluded that the species was not susceptible to these parasites. This does not agree with the results obtained by us and by Rojo-Vazquez & Cordero-Del-Campillo (1974) as regards the experimental susceptibility of this mollusc as an intermediate host of N. linearis.…”

“…On comparing the results obtained for C. nemoralis and Helix (C.) aspersa with those of Rojo-Vazquez & Cordero-Del-Campillo (1974), when they infected the same species of molluscs with doses of Ll of N. linearis similar to those we used, the percentage of Ll that penetrated the molluscs was higher in our experiments. However, the period of time needed for the observation of the different larval stages of N. linearis was longer in our study than in that carried out by Rojo-Vazquez & Cordero-Del-Campillo (1974). Miiller (1934) also indicated shorter periods of time than us for detecting the first L2 and L3 of N. linearis in C. nemoralis.…”

“…The number of days needed before the observation of the different larval stages in the molluscs was greater than that indicated by Muller (1934), Rojo-Vazquez & Cordero-Del-Campillo (1974) and Marcos-Martinez (1975). It was smaller than that mentioned by Urban (1980) and Manga-Gonzalez & Morrondo-Pelayo (1988), and similar to that recorded by Morrondo-Pelayo et al (1980, 1981, Morrondo-Pelayo & Manga-Gonzalez (1982), Reguera-Feo et al (1980) and Reguera-Feo (1983).…”

“…Moreover, due to the important role that such widespread and abundant mollusc species as Cepaea nemoralis (Linnaeus, 1758) and Helix (Cryptomphalus) aspersa Miiller, 1774 can play in verminous bronchopneumonia epidemiology, we decided to carry out a seriated methodical study of the larval development of N. linearis in the molluscs named. This study would allow us, on the one hand, to investigate thoroughly the aspects of C. nemoralis, already studied by Miiller (1934), and of both species studied by Rojo-Vazquez & Cordero-Del-Campillo (1974) and, on the other hand, to tackle aspects not studied by them. The results obtained should be of great use in understanding the bionomics of this parasite and in taking suitable steps to control the illness it produces.…”

“…Μέσα στο σώμα των μαλακίων, οι εισερχόμενες α΄ σταδίου προνύμφες μετατρέπονται σε β' σταδίου, χωρίς όμως να αποβάλλουν το επιδερματίδιο του α' σταδίου, εκδύονται δύο φορές και εξελίσσονται σε μολύνουσες γ' σταδίου σε 10-14 ημέρες (F. Muller, 1934). Σύμφωνα με τους Rojo-Vazquez et al (1974), Castanon -Ordonez et al (1984), Kassai et al (1988) Kassai (1964), Cabaret (1980), Boev (1984.…”
