Study Of Sensitivity Levels In Six Species Of Iranian Scorpions Against Chemical Pesticides

In this study the sensitivity level of scorpions, H.lepturus, M.eupeus, A.crassicauda, O.doria, S maurus and B.sulcyito insecticides (Lindane, Malathion, Propoxur, Diazinon, Cypermethrin and Chlorpyrifos) were studied. For determining sensitivity level in scorpions to pesticides, the same method of sensitivity of cockroaches to insecticides were used. The results showed that Lindance (Vetabl Powder 25%) in ranges of 0.1-0.16 mg/cm2 (25-40 pglcm2 poison technique ), Chlopyrifos (Emulsion 40%) in amount of 0.02-0.033 p li/cm2 (8-13:2 p g/cm2 poison technique), Diazinon (Emulsion 60%) 0.02-0.026 p li/cm2 (12-15.6 p g/cm2 poison technique), Cypermethrin (Emulsion 10%) 0.087-0.113 pli/cm2 (8.7-11.3 pg/cm2 poison technique), propoxur (Emulsion 20%) and Malathion (Emolsion 57%) in amounts 0.075 pli/cm2 (15 pg/cm2 poison technique) and 0.13-0.173 pli/cm2 (74-98.61 pg/cm2 technique poison) after five minutes in touch with poisonous area created 100% mortality rates in above scorpions.except in S. maurus species within 24-48 HS.
