Comparison of the effect of fuxim and mactomil poisons on Ripicephalus mite with the pocket larva test method

Ticks are one of the most important obligate and external blood-feeding parasites of terrestrial vertebrates. This terminus can harm its host by sucking blood and transmits many pathogenic organisms that cause animal and human diseases. To carry out this study, 434 ticks were collected from 2360 sheep and 123 cows from villages around Durood city. The samples were taken to the laboratory for testing. Because the purpose of the investigation was the cephalus tick, we grouped this tick into 4 groups including male and female groups with different weights. We prepared different dilutions of fuxim and cypermethrin with normal water and exposed each group to these toxins by flotation method. The effect of poison on the larvae of Rhipicephalus sanguineus mite was investigated by the method of preparing a filter bag .Rhipicephalus female tick showed more resistance to cypermethrin poison, therefore, excessive consumption of poisons should be prevented and on the other hand, poisons should be used in combination to prevent tick resistance
