accumulation of acaricide resistance mechanisms in rhipicephalus (boophilus) microplus (acari: ixodidae) populations from new caledonia island. | rhipicephalus (boophilus) microplus has been pesticide-controlled for several decades in the pacific island of new caledonia. since 1996, pesticide-control has been based on either deltamethrin (butox) or amitraz (taktic) in herds harbouring deltamethrin-resistant ticks. in this island, the first r. microplus deltamethrin- and amitraz-resistances were detected in 1992 and 2003, respectively. using lpt bioassays, we have undertaken to update data regarding the geographical distribution and the ph ... | 2007 | 17560723 |
in vitro and in vivo evaluation of deltamethrin and amitraz mixtures for the control of rhipicephalus (boophilus) microplus (acari: ixodidae) in new caledonia. | acaricide resistance is a major problem that hinders the control of the tropical cattle tick, rhipicephalus (boophilus) microplus (canestrini), in many parts of the world where cattle production continues to suffer severe economic losses to tick infestation. deltamethrin and amitraz have been used alone to control r. microplus in new caledonia for the past decade, and tick populations have developed resistance to both acaricides. a study was conducted to evaluate the effectiveness of deltamethri ... | 2008 | 18565679 |
swift sympatric adaptation of a species of cattle tick to a new deer host in new caledonia. | the occurrence and frequency of sympatric speciation in natural systems continue to be hotly debated issues in evolutionary biology. this might reflect the timescale over which evolution occurs resulting in there being few compelling observations of the phenomenon (lake fishes, phytophagous insects and island trees). despite predictions, few examples of sympatric speciation have been recorded in animal parasites, at least widely accepted as such. here we show that, in new caledonia, the monophas ... | 2010 | 20601171 |
a campaign to eradicate bovine babesiosis from new caledonia. | in december 2007, babesia bovis was introduced to new caledonia through the importation of cattle that had been vaccinated with a live tick fever (babesiosis and anaplasmosis) vaccine. although the tick rhipicephalus (boophilus) microplus is common in new caledonia, the territory had previously been free of tick-borne diseases of cattle. this paper describes the initial extent of the outbreak, the measures and rationale for disease control, and the progress to date of the eradication campaign. i ... | 2011 | 21771538 |
bartonellae in animals and vectors in new caledonia. | bartonellae are gram-negative facultative intracellular alpha-proteobacteria from the family bartonellaceae. the natural history of bartonellae consists of a reservoir/host, which is a vertebrate with chronic intravascular infection with sustained bacteremia, and a vector (usually an arthropod) that transfers the bacteria from the reservoir to a susceptible yet uninfected host. in order to reveal the sources and reservoirs of bartonella infection in animals and vectors in new caledonia, we colle ... | 2011 | 22018646 |
