From 23 samples trapped in various localities and subsequently reared in the laboratory, susceptibilities were measured against lindane, pyrethrin + PBO, trichlorfon, dichlorvos, and propoxur, the most used insecticides against cockroaches in our country. Detection of resistance was done with discriminating doses and the degree of resistance was measured with the doses-mortality method in deposit tests. In no case we found any resistance to propoxur but, for the first time, strains with a low resistance to dichlorvos. There was a distinct increase in the resistance to lindane, trichlorfon and pyrethrins + PBO during the lost years. A strain selected with pyrethrins in the laboratory showed marked group resistance to all tested pyrethroids (permethrin, cyfluthrin, cypermethrin, tetramethrin, deltamethrin, bioresmethrin, bioallethrin), but no cross resistance to the other insecticides.</p>","PeriodicalId":75492,"journal":{"name":"Angewandte Parasitologie","volume":"31 2","pages":"79-93"},"PeriodicalIF":0.0,"publicationDate":"1990-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12861737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
