Abstract:
The effects of sublethal concentrations of methanol extract of sesbania sesban plant on survival rate, egg laying of Bulinus truncatus snails, hatchability of their eggs, infection rate with Schistosoma haematobium miracidia, cercarial production and certain physiological parameters of treated snails were studied. The sublethal concentrations of the tested plant extract (LC0, LC10 and LC25) caused considerable reduction in survival rates; egg production of B. runcates snails; hatchability of eggs as well as in the infectivity of Schistosoma haematobium miracidia to the snail. Also, the tested concentrations reduced the cercarial production per snail and the period of cercarial shedding. The glucose level in haemolymph of exposed snails was elevated while the glycogen, protein content and the activities of hexokinase (HK), pyruvatekinase (PK) and lactate dehydrogenase (LDH) showed a decrease in soft tissues when compared with the control group. It was concluded that the app lication of sublethal concentration of methanol extracts of Sesania sesban may be helpful in snail control as it interferes with the snails' biology and physiology.
