The results obtained are compared with data previously obtained for difenacoum, another member of the same series of 4-hydroxycoumarin anticoagulants.<\/jats:p><jats:p>With warfarin-resistant and non-resistant common rats, complete kills were obtained using a concentration of 0\u00b70005% for 2 days, or 0\u00b7001 % for 1 day: a 1-day test at 0\u00b70005% killed 6 out of 10 and 17 out of 20 of the two types respectively. At 0\u00b7005% complete kills of resistant ship rats were obtained after 2 days exposure and of resistant house mice after 1 day, but at 0\u00b7002% for 2 days there was some survival. Non-resistant ship rats and house mice were all killed after 2 days feeding on 0\u00b7002% bait.<\/jats:p><jats:p>In 2-day palatability tests, <jats:italic>R. norvegicus<\/jats:italic> showed no significant aversion to the poison at 0\u00b7002% and 100% mortality was obtained. The poison was significantly unpalatable to <jats:italic>R. rattus<\/jats:italic> at 0\u00b7005% and to <jats:italic>M. musculus<\/jats:italic> at 0\u00b7005% and 0\u00b7002 %, although with the last species these concentrations gave complete kills.<\/jats:p><jats:p>It is concluded that WBA 8119 has greater activity than other known anticoagulants against the three commensal species examined. The laboratory results suggest that concentrations between 0\u00b70005% and 0\u00b7002% would be suitable for field use against common rats, and between 0\u00b7002% and 0\u00b7005% for ship rats and house mice.<\/jats:p>","DOI":"10.1017\/s0022172400055807","type":"journal-article","created":{"date-parts":[[2009,5,15]],"date-time":"2009-05-15T09:53:04Z","timestamp":1242381184000},"page":"419-426","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":65,"title":["Laboratory evaluation of WBA 8119 as a rodenticide for use against warfarin-resistant and non-resistant rats and mice"],"prefix":"10.1017","volume":"77","author":[{"given":"R.","family":"Redfern","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
