Abstract

This study aimed to investigate the effect of the water suspension of Anagallis arvensis or Calendula micrantha plants, as well as Bayluscide and copper sulphate on the haemocytes of Biomphalaria alexandrina snails at ultrastructural level at three sublethal concentrations of LC0, LC10, and LC25. Examinations were performed after 2 and 4 weeks of exposure. The total number of the haemocytes granulocytes, hyalinocytes and amoebocytes was found to be significantly reduced (P
