Survey of Susceptibility of Cockroaches To Pyrethroids Insecticides in sari Hospital in 1383
Abstract Background and purpose: The medical importance of cockroaches is much greater than what has generally been realized. They are known to carry pathogenic viruses and bacteria such as escherichia coli, Staphylococcus aureus and salmonella species including S.typhi and S.typhimurium. As a resul...

| description | Abstract Background and purpose: The medical importance of cockroaches is much greater than what has generally been realized. They are known to carry pathogenic viruses and bacteria such as escherichia coli, Staphylococcus aureus and salmonella species including S.typhi and S.typhimurium. As a result, their eradication is very important.Materials and Methods: One of the best and effective ways of controlling cockoaches is thought to be the chemical method, which is performed by insecticides. It should be stated that the chemical treatment must be combined with enviromental sanitation, otherwise, the results will not be satisfactory. This study was carried out by using four different insecticides like: Permethrin 0.92% Deltamethrin 0.98% and Supermithrin 0.92% to evaluate their susceptibility and resistance.In this study, the cockroaches were collected from Imam Khomeini and Boo Ali Hospitals in Sari and were tested by different cocentrations of above -mentioned insecticides. Susecptibility of cockroaches was performed according to the standards of World Health Organization (W.H.O).Results: In this study, all the strains of cockroaches were exposed to the concentration of the above-mentioned insecticides through surface contact method. Imam Khomeini strain showed the LT50 of 20/24, 19/30, 19/64 minutes and Boo Ali hospitals 19/87, 17/6, 18/66 minutes. For susceptible strain, 8/89, 8/8, 8/64 minutes were obtained to Permethrin, Deltamethrin and Sumithrin respectively. On the other hand, LT90 for Imam Khomeini strain were 42/91, 41/21, 37/38 minutes and Boo Ali hospitals 42/59, 40/88, 34/05 minutes. For susceptible strain, 17/58, 18/43, 17/28 minutes were obtained to Permethrin, Deltamethrin and Supermithrin respectively. In surface contact, the resistance ratio (RR) to pyrethroids insecticides (Permethrin, Deltamethrin and Supermithrin) of BoAli hospitals strain was 2/23, 2 and 2/15 respectively, while this ratio for Imam Khomeini strain was 2/2, 2/19 and 2/27.Conclusion: Direct use of permethrin, Deltamethrin and supermithrin has developed the resistance of German cockroaches significantly |
