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 ...19751221351

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 ...19846364800
geographic distribution of angiostrongylus cantonensis in wild rats (rattus rattus) and terrestrial snails in florida, usa.the parasitic nematode angiostrongylus cantonensis is a major cause of eosinophilic meningitis in humans, and has been documented in other incidental hosts such as birds, horses, dogs and non-human primates. it is endemic in hawaii, and there have been sporadic reports in the southern continental united states. this parasite uses rats as definitive hosts and snails as intermediate hosts. in this study, we collected potential definitive and intermediate hosts throughout florida to ascertain the g ...201728542310
wild-rodent-flea control in rural areas of an enzootic plague region in hawaii; a preliminary investigation of methods.preliminary field tests were carried out to develop methods for controlling fleas on wild rodents in the enzootic plague region of the island of hawaii. among several designs, a metal hood-type ddt bait-box was developed which was simple in design, low in cost, easy to transport to and maintain in the field, protected the insecticide from the elements, and attracted all species of field rats inhabiting a gulch in the hamakua district. these rats-rattus rattus (and its subspecies), r. norvegicus, ...195513260882
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 ...201120552335
