TI - Molluscicldal activity and biochemical effects of certain monoterpenolds against land snails KW - Snails as carriers of disease KW - Snails KW - Control KW - monoterpenoids N1 - Includes reference N2 - The monoterpenoid compounds fenchone, fenchol and thymol were tested for their molluscicidal actiVity against two terrestrial snails Eobania vermiculata (Muiler) and Thaba pisana (Muiler). Fenchone exhibtted molluscicldal aelivity against both of tested snails T. pisana and E. vermiculata with Ld50. values of 527.93 and 552.38 ug/g body weight respectively. Fenchol was active against E. vermiculata with Ld50 664.22 ug/g body weight while thymol exhibtted molluscicidal aelion against T. pisana (LOso = 516.15 Ilg/g body weight). Sub-lethal doses of fenchone caused marked decrease in protein level of the two snail species. Aspartate transaminase (AST) and alanin transaminase (ALT) activities were stimulated by the most tested doses of fenchone.. Response of ALT toward fenchone treatments was more sensitive than AST. The two tested enzymes of E. vermiculata were more responsive than those of T.pisana to fencbone treatments UR - http://nile.enal.sci.eg/EALE/2007/AAR/1207/4/679.pdf ER -
