In order to assess of tick resistance against domestic commercial acaricidal compounds ,a standard technique is the main requirement of a resistance test.It should be capable for application to any commercial formulated pesticide , the next requirement is simpilicity and high susceptibility of test and also the low cost of the test has been interested. In this study , the lack of FAO`s inpregnated filter paper pocket has been dissolved , whereby, the filter paper can be easily imperegnated with each concentration of commercial acaricides then instesd of having sandwich paper, it was modified in pocket shape.our modification might have some advantages in having the same suitability of resistance screening of each insecticde as reference material. Probit analysis of these results indicated that minimum lethal concentration to kill 50 % of tick larvae of Boophilus annulatus was 0.003 and expected concentration to give 99% mortality of the tick larvae was 0.01 which equal to 1:20 of the recommended dose of diazinon. It can be concluded that obtained base line data and reggration line are drown to fit this point that it revealed , the tick populations did not show any resistance status in this monitoring test.
