| Abstract |
The toxicity and biochemical effects of methomyl and diazinon insecticides were studied as bait or contact against the different ages of land snails Eobania vermiculata and Monacha obstructa [one month, Six months, adult (9-12) and old adult(over 24 month)]. Results showed that methomyl was more toxic for Eobania vermiculata than Monacha obstructa when used as bait in the all-different ages. Also, Eobania vermiculata was more susceptible than Monacha obstructa to methomyl as contact for the most ages. Regarding diazinon compound, Monacha obstructa was more susceptible to diazinon as bait than Eobania vermiculata at one, three and six month age but vice versa occurred for the old aged animals (over 24 month) and the toxic effect was equal for both species at the adult age. Concerning the contact method, diazinon was more toxic to Eobania vermiculata than Monacha obstructa at the three-month and old ages. It was clear from the results that the young age (one-month) was the most susceptible to both pesticides. Therefore, these results will help in the choice of proper time for pesticide application. Regarding the repellent effect, methomyl was more repellency for Eobania vermiculata than Monacha obstructa while vice versa occurred with diazinon. The effect of both compounds on the biochemical parameters (AchE, LDH, AST, total protein, total lipid) was determined. Results showed a decrease in the AchE activity as a site of action for the both chemicals. However, the results of the other biochemical parameters their activities or the contents were fluctuated according to their age and physiological situation of the test animals. Generally, it could be concluded that the response and susceptibility of snails to pesticides differed according to different parameters i.e. chemical structure of pesticide, method of application, snail species, age of snail and periods after treatment.
