| mirex residues in wildlife and soils, hawaiian pineapple-growing areas--1972-74. | a monitoring program was conducted in the pineapple-growing areas of hawaii from 1972 to 1974 to survey mirex residues in sediments, soils, and aquatic and terrestrial wildlife. residues in pineapple field soils ranged from 3 to 18 ppb 9 months after mirex had been applied. no residues were found in the sediments. only 8 fish of 110 aquatic animals sampled contained mirex; these levels were low and ranged from 3 to 7 ppb. mirex residues in birds ranged from undetectable to 10 ppm; residues in ro ... | 1975 | 1221351 |
| efficacy of rodenticide baits for the control of three invasive rodent species in hawaii. | we tested the efficacy and palatability of nine commercial rodenticide bait formulations on polynesian rats (rattus exulans), roof rats (r. rattus), and house mice (mus musculus). efficacy varied by rodenticide tested and rodent species. generally, rodenticides were more effective against mice than for either of the rat species, and mice tended to consume more rodenticide bait than the laboratory chow alternative food. efficacy was generally highest for the second-generation anticoagulants teste ... | 2011 | 20552335 |
| results of a preliminary serological survey of small mammal populations for plague on the island of hawaii. | since 1910 the district of hamakua, island of hawaii, has been considered an endemic plague area. to obtain indirect evidence of plague infection in rodents and in the mongoose, serological surveys of the small mammal populations were undertaken. the passive microhaemagglutination test demonstrated the presence of positive reactors (titres of 1:16 and higher) in the sera of 2641 rodents and 385 mongooses tested. positive percentages were: rattus exulans, 1.5%; r. norvegicus, 1.9%; r. rattus, 0.6 ... | 1965 | 5295405 |
| evidence for the extinction of plague in hawaii. | plague (infection by yersinia pestis) was present in hawaii for the period 1899-1957 and caused at least 370 fatalities. the first infections came from immigrant commensal rats, probably rattus rattus and rattus norvegicus, on ships from the orient. both species were already established in hawaii and became the widespread local carriers of plague, supplemented by rattus exulans which had colonized the islands in ancient polynesian times. the flea xenopsylla vexabilis arrived with r. exulans, and ... | 1984 | 6364800 |
